IoT, or the Internet of Things, is a technological field that makes it possible for users to connect devices and systems and exchange data over the internet. Through DZone's IoT resources, you'll learn about smart devices, sensors, networks, edge computing, and many other technologies — including those that are now part of the average person's daily life.
With growing concern regarding data privacy and data safety today, Internet of Things (IoT) manufacturers have to up their game if they want to maintain consumer trust. This is the shared goal of the latest cybersecurity standard from the European Telecommunications Standards Institute (ETSI). Known as ETSI EN 303 645, the standard for consumer devices seeks to ensure data safety and achieve widespread manufacturer compliance. So, let’s dive deeper into this standard as more devices enter the home and workplace. The ETSI Standard and Its Protections It counts a long name but heralds an important era of device protection. ETSI EN 303 645 is a standard and method by which a certifying authority can evaluate IoT device security. Developed as an internationally applicable standard, ETSI offers manufacturers a baseline for security rather than a comprehensive set of precise guidelines. The standard may also lay the groundwork for various future IoT cybersecurity certifications in different regions around the world. For example, look at what’s happening in the European Union. Last September, the European Commission introduced a proposed Cyber Resilience Act, intended to protect consumers and businesses from products with inadequate security features. If passed, the legislation — a world-first on connected devices — will bring mandatory cybersecurity requirements for products with digital elements throughout their whole lifecycle. The prohibition of default and weak passwords, guaranteed support of software updates and mandatory testing for security vulnerabilities are just some of the proposals. Interestingly, these same rules are included in the ETSI standard. IoT Needs a Cybersecurity Standard Shockingly, a single home filled with smart devices could experience as many as 12,000 cyber attacks in a single week. While most of those cyber attacks will fail, the sheer number means some inevitably get through. The ETSI standard strives to keep those attacks out with basic security measures, many of which should already be common sense, but unfortunately aren’t always in place today. For example, one of the basic requirements of the ETSI standard is no universal default passwords. In other words, your fitness tracker shouldn’t have the same default password as every other fitness tracker of that brand on the market. Your smart security camera shouldn’t have a default password that anyone who owns a similar camera could exploit. It seems like that would be common sense for IoT manufacturers, but there have been plenty of breaches that occurred simply because individuals didn’t know to change the default passwords on their devices. Another basic requirement of ETSI is allowing individuals to delete their own data. In other words, the user has control over the data a company stores about them. Again, this is pretty standard stuff in the privacy world, particularly in light of regulations like Europe’s General Data Protection Regulation (GDPR) and California’s Consumer Privacy Act (CCPA). However, this is not yet a universal requirement for IoT devices. Considering how much health- and fitness-related data many of these devices collect, consumer data privacy needs to be more of a priority. Several more rules in ETSI have to do with the software installed on such devices and how the provider manages security for the software. For example, there needs to be a system for reporting vulnerabilities. The provider needs to keep the software up to date and ensure software integrity. We would naturally expect these kinds of security measures for nearly any software we use, so the standard is basically just a minimum for data protection in IoT. Importantly, the ETSI standard covers pretty much everything that could be considered a smart device, including wearables, smart TVs and cameras, smart home assistants, smart appliances, and more. The standard also applies to connected gateways, hubs, and base stations. In other words, it covers the centralized access point for all of the various devices. Why Device Creators Should Implement the Standard Today Just how important is the security standard? Many companies are losing customers today due to a lack of consumer trust. There are so many stories of big companies like Google and Amazon failing to adequately protect user data, and IoT in particular has been in the crosshairs multiple times due to privacy concerns. An IoT manufacturer that doesn’t want to lose business, face fines and lawsuits, and damage the company's reputation should consider implementing the ETSI standard as a matter of course. After all, these days a given home might have as many as 16 connected devices, each an entry point into the home network. A company might have one laptop per employee but two, three, or more other smart devices per employee. And again, each smart device is a point of entry for malicious hackers. Without a comprehensive cybersecurity standard like ETSI EN 303 645, people who own unprotected IoT devices need to worry about identity theft, ransomware attacks, data loss and much more. How to Test and Certify Based on ETSI Certification is fairly basic and occurs in five steps: Manufacturers have to understand the 33 requirements and 35 recommendations of the ETSI standard and design devices accordingly. Manufacturers also have to buy an IoT platform that has been built with the ETSI standard in mind, since the standard will fundamentally influence the way the devices are produced and how they operate within the platform. Next, any IoT manufacturer trying to meet the ETSI standard has to fill out documents that provide information for device evaluation. The first document is the Implementation Conformance Statement, which shows which requirements and recommendations the IoT device does or doesn’t meet. The second is the Implementation eXtra Information for Testing, which provides design details for testing. A testing provider will next evaluate and test the product based on the two documents and give a report. The testing provider will provide a seal or other indication that the product is ETSI EN 303 645-compliant. With new regulations on the horizon, device manufacturers and developers should see it as best practice to get up to speed with this standard. Better cybersecurity is not only important for consumer protection but brand reputation. Moreover, this standard can provide a basis for stricter device security certifications and measures in the future. Prepare today for tomorrow.
While a lot of my inspiration for blog posts come from talking with New Relic users, it's hard to share them as examples because their so specific and often confidential. So I find myself struggling more to find a generic "for instance" that's easy to understand and accessible to all everyone. Which should explain why I use my home environment as the sample use case so often. Even if you don't have exactly the same gear or setup I do, it's likely you have something analogous. On top of that, if you don't have the specific element I'm discussing, many times I believe it's something you ought to consider. That brings us to my example today: Pi-Hole. Pi-Hole acts as a first-level DNS server for your network. But what it REALLY does is make your network faster and safer by blocking requests to malicious, unsavory, or just plain obnoxious sites. If you’re using Pi-Hole, it’ll be most noticeable in the ways advertisements on a webpage load. BEFORE: pop-overs and hyperbolic ads AFTER: No pop-overs, spam ads blocked But under the hood, it’s even more significant. BEFORE: 45 seconds to load AFTER: 6 seconds to load Look in the lower-right corner of each of those images. Load time without Pi-Hole was over 45 seconds. With it, the load time was 6 seconds. You may there are many pages like this, but the truth is web pages link to these sites all the time. Here's the statistics from my house on a typical day. How Does the Pi-Hole API Work? If you have Pi-Hole running, you get to the API by going to http://<your pi-hole url>/admin/api.php?summaryRaw. The result will look something like this: {”domains_being_blocked”:115897,”dns_queries_today”:284514,”ads_blocked_today”:17865,”ads_percentage_today”:6.279129,”unique_domains”:14761,”queries_forwarded”:216109,”queries_cached”:50540,”clients_ever_seen”:38,”unique_clients”:22,”dns_queries_all_types”:284514,”reply_NODATA”:20262,”reply_NXDOMAIN”:19114,”reply_CNAME”:16364,”reply_IP”:87029,”privacy_level”:0,”status”:”enabled,””gravity_last_updated”:{”file_exists”:true,”absolute”:1567323672,”relative”:{”days”:”3,””hours”:”09,””minutes”:”53”}} Let's format the JSON data so it looks a little prettier: The point is, once we have access to all that JSON-y goodness, it's almost trivial (using the Flex integration, which I discussed in this series) to collect and send into New Relic, to provide further insight into how your network is performing. At that point, you can start to include the information in graphs like this: Assuming you have the New Relic infrastructure agent installed on on any system on the network that can access your pihole (and once again, if you need help getting that set up, check out my earlier blog post here) you have relatively few steps to get up and running. First, the YAML file would look like this (you can also find it on the New Relic Flex GitHub repo in the examples folder). integrations: - name: nri-flex config: name: pihole_simple apis: - name: pihole_simple url: http://pi.hole/admin/api.php?summaryRaw&auth= #<your API Key Here> headers: accept: application/json remove_keys: - timestamp Next, the NRQL you'd need to set up two different charts are as follows: For the "Query Volume" chart: From pihole_simpleSample SELECT average(dns_queries_all_replies), average(dns_queries_today), average(queries_forwarded), average(queries_cached), average(dns_queries_all_types) TIMESERIES For the "Blocking Activity" chart: From pihole_simpleSample SELECT average(ads_blocked_today), average(domains_being_blocked) TIMESERIES This is, of course, only the start of the insights you can gain from your Pi-Hole server (and by extension, ANY device or service that has an API with endpoints that provide data). If you find additional use cases, feel free to reach out to me in the comments below, on social media, or when you see me at a conference or meet-up.
This article is about how Apache Doris helps you import data and conduct Change Data Capture (CDC) from upstream databases like MySQL to Doris based on Flink streaming. But first of all, you might ask: What is Apache Doris and why would I bother to do so? Well, Apache Doris is an open-source real-time analytical data warehouse that supports both high-concurrency point queries and high-throughput complex analysis. It provides sub-second analytic query capabilities and comes in handy in multi-dimensional analysis, dashboarding, and other real-time data services. Overview How to perform end-to-end data synchronization within seconds How to ensure real-time data visibility How to smoothen the writing of massive small files How to ensure end-to-end Exactly-Once processing Real-Timeliness Stream Write The Flink-Doris Connector in Doris used to follow a "Cache and Batch Write" method for data ingestion. However, that requires a wise choice of batch size and batch write interval; otherwise things could go wrong. For example, if the batch size is too large, OOM errors could occur. On the other hand, frequent writes could lead to too many data versions generated. To avoid such troubles, Doris implements a Stream Write method, which works as follows: A Flink task, once started, asynchronously initiates a Stream Load HTTP request. The data is transmitted to Doris via the chunked transfer encoding mechanism of HTTP. The HTTP request ends at Checkpoint, which means the Stream Load task is completed. Meanwhile, the next Stream Load request will be asynchronously initiated. Repeat the above steps. Transaction Processing Quick Aggregation of Data Versions Highly concurrent writing of small files can generate too many data versions in Doris and slow down data queries. Thus, Doris has enhanced its data compaction capability in order to quickly aggregate data. Firstly, Doris introduced Quick Compaction. Specifically speaking, data compaction will be triggered once data versions increase. Meanwhile, by scanning the metadata of tablets, Doris can identify those tablets with too many data versions and conduct compaction correspondingly. Secondly, for the writing of small files, which happens in high concurrency and frequency, Doris implements Cumulative Compaction. It isolates these compaction tasks from the heavyweight Base Compaction from a scheduling perspective to avoid mutual influence between them. Last but not least, Doris adopts a tiered data aggregation method, which ensures that each aggregation only involves files of similar sizes. This greatly reduces the total number of aggregation tasks and the CPU usage of the system. Exactly-Once The Exactly-Once semantics means that the data will be processed once and only once. It prevents the data from getting reprocessed or lost even if the machine or application fails. Flink implements a 2PC protocol to realize the Exactly-Once semantics of Sink operators. Based on this, the Flink-Doris Connector in Doris implements Stream Load 2PC to deliver Exactly-Once processing. The details are as follows: A Flink task will initiate a Stream Load PreCommit request once it is started. Then, a transaction will be opened, and data will be continuously sent to Doris via the chunked mechanism of HTTP. The HTTP request ends at Checkpoint and the Stream Load is completed. The transaction status will be set to Pre-Committed. At this time, the data has been written to BE and become invisible to users. The Checkpoint initiates a request and changes the transaction status to Committed. After this, the data will become visible to users. In the case of Flink application failures, if the previous transaction is in Pre-Committed status, the Checkpoint will initiate a rollback request and change the transaction status to Aborted. Performance of Doris in High-Concurrency Scenarios Scenario Description Import data from Kafka using Flink. After ETL, use the Flink-Doris Connector for real-time data ingestion into Doris. Requirements The upstream data is written into Doris at a high frequency of 100,000 per second. To achieve real-time data visibility, the upstream and downstream data needs to be synchronized within around 5s. Flink Configurations Concurrency: 20 Checkpoint Interval: 5s Here's how Doris does it: Compaction Real-TimelinessAs the result shows, Doris manages to aggregate data quickly and keep the number of data versions in tablets below 50. Meanwhile, the Compaction Score remains stable. CPU UsageAfter optimizing the compaction strategy of small files, Doris reduces CPU usage by 25%. Query LatencyBy reducing the CPU usage and the number of data versions, Doris arranges the data more orderly and thus enables much lower query latency. Performance of Doris in Low-Latency Scenarios (High-Level Stress Test) Description Single-BE, single-tablet Stream Load stress test on the client side Data real-timeliness <1s Here are the Compaction Scores before and after optimization: Suggestions for Using Doris Low-Latency ScenariosAs for scenarios requiring real-time data visibility (such as data synchronization within seconds), the files in each ingestion are usually small in size. Thus, it is recommended to reduce cumulative_size_based_promotion_min_size_mbytefrom the default value of 64 to 8 (measured in MB). This can greatly improve the compaction performance. High-Concurrency ScenariosFor highly concurrent writing scenarios, it is recommended to reduce the frequency of Stream Load by increasing the Checkpoint interval to 5–10s. This not only increases the throughput of Flink tasks, but also reduces the generation of small files and thus avoids extra pressure on compaction. In addition, for scenarios with less strict requirements for real-timeliness (such as data synchronization within minutes), it is recommended to increase the Checkpoint interval to 5–10 minutes. In this way, the Flink-Doris Connector can still ensure data integrity via the 2PC+Checkpoint mechanism. ConclusionApache Doris realizes data real-timeliness by its Stream Write method, transaction processing capability, and aggregation of data versions. These techniques help it reduce memory and CPU usage, which enables lower latency. In addition, for data integrity and consistency, Doris implements Stream Load 2PC to guarantee that all data is processed exactly once. This is how Doris facilitates quick and safe data ingestion.
As more companies combine Internet of Things (IoT) devices and edge computing capabilities, people are becoming increasingly curious about how they could use artificial intelligence (AI) to optimize those applications. Here are some thought-provoking possibilities. Improving IoT Sensor Inference Accuracy With Machine Learning Technology researchers are still in the early stages of investigating how to improve the performance of edge-deployed IoT sensors with machine learning. Some early applications include using sensors for image-classification tasks or those involving natural language processing. However, one example shows how people are making progress. Researchers at IMDEA Networks recognized that using IoT sensors for specific deep-learning tasks may mean the sensors cannot guarantee specific quality-of-service requirements, such as latency and inference accuracy. However, the people working on this project developed a machine learning algorithm called AMR² to help with this challenge. AMR² utilizes an edge computing infrastructure to make IoT sensor inferences more accurate while enabling faster responses and real-time analyses. Experiments suggested the algorithm improved inference accuracy by up to 40% compared to the results of basic scheduling tasks that did not use the algorithm. They found an efficient scheduling algorithm such as this one is essential for helping IoT sensors work properly when deployed at the edge. A project researcher pointed out that the AMR² algorithm could impact an execution delay if a developer used it for a service similar to Google Photos, which classifies images by the elements they include. A developer could deploy the algorithm to ensure the user does not notice such delays when using the app. Reducing Energy Usage of Connected Devices With AI at the Edge A 2023 study of chief financial officers at tech companies determined 80% expect revenue increases in the coming year. However, that’s arguably most likely to happen if employees understand customers’ needs and provide products or services accordingly. The manufacturers of many IoT devices intend for people to wear those products almost constantly. Some wearables detect if lone workers fall or become distressed or if people in physically demanding roles are becoming too tired and need to rest. In such cases, users must feel confident that their IoT devices will work reliably through their workdays and beyond. That’s one of the reasons why researchers explored how using AI at the edge could improve the energy efficiency of IoT devices deployed to study the effects of a sedentary lifestyle on health and how correct posture could improve outcomes. Any IoT device that captures data about how people live must collect data continuously, requiring few or no instances where information gathering stops because the device runs out of battery. In this case, subjects wore wireless devices powered by coin-cell batteries. Each of these gadgets had inertia sensors to collect accurate data about how much people moved throughout the day. However, the main problem was the batteries only lasted a few hours due to the large volume of data transmitted. For example, research showed a nine-channel motion sensor that reads 50 samples every second produces more than 100 MB of data daily. However, researchers recognized machine learning could enable the algorithms only to transfer critical data from edge-deployed IoT devices to smartphones or other devices that assist people in analyzing the information. They proceeded to use a pre-trained recurrent neural network and found the algorithm achieved real-time performance, improving the IoT devices’ functionality. Creating Opportunities for On-Device AI Training Edge computing advancements have opened opportunities to use smart devices in more places. For example, people have suggested deploying smart street lights that turn on and off in response to real-time traffic levels. Tech researchers and enthusiasts are also interested in the increased opportunities associated with AI training that happens directly on edge-deployed IoT devices. This approach could increase those products’ capabilities while reducing energy consumption and improving privacy. An MIT team studied the feasibility of training AI algorithms on intelligent edge devices. They tried several optimization techniques and came up with one that only required 157 KB of memory to train a machine-learning algorithm on a microcontroller. Other lightweight training methods typically require between 300-600 MB of memory, making this innovation a significant improvement. The researchers explained that any data generated for training stays on the device, reducing privacy concerns. They also suggested use cases where the training happens throughout normal use, such as if algorithms learn by what a person types on a smart keyboard. This approach had some undoubtedly impressive results. In one case, the team trained the algorithm for only 10 minutes, which was enough to allow it to detect people in images. This example shows optimization can go in both directions. Although the first two examples here focused on improving how IoT devices worked, this approach enhanced the AI training process. However, suppose developers train algorithms on IoT devices that will eventually use them to perform better. That’s a case where the approach mutually benefits AI algorithms and IoT-edge devices. How Will You Use AI to Improve How IoT-Edge Devices Work? These examples show some of the things researchers focused on when exploring how artificial intelligence could improve the functionality of IoT devices deployed at the edge. Let them provide valuable insights and inspiration about how you might get similar results. It’s almost always best to start with a clearly defined problem you want to solve. Then, start exploring how technology and innovative approaches could help meet that goal.
Let’s build an IoT application with weather sensors deployed around the globe. The sensors will collect data and we store the data along with the IDs of the sensors. We’ll run multiple database instances, and the sensors will write to the geographically closest database. All databases will regularly exchange data, so all the databases will eventually have data from all the sensors. We need each sensor to have a globally unique ID. How can we achieve it? For example, we could run a service assigning sensor IDs as a part of the sensor installation procedure. It would mean additional architectural complexity, but it's doable. Sensor IDs are immutable, so each sensor needs to talk to the ID service only once - right after the installation. That’s not too bad. What if we need to store a unique ID for each data reading? Hitting the centralized ID service whenever we need to store data is not an option. That would stress the ID service too much, and when the ID service is unavailable, no sensor could write any data. What are the possible solutions? In the simplest case, each sensor could talk to the remote ID service and reserve a block of IDs it could then assign locally without further coordination. When it exhausts the block, it asks the ID service for a new one. This strategy would reduce the load on the ID service, and sensors could function even when the ID service is temporarily unavailable. We could also generate local reading IDs and prefix them with our unique immutable sensor ID. We could also be smart and use fancy ID algorithms like FlakeIDs. The strategies mentioned aim to minimize the need for coordination while ensuring that the IDs are unique globally. The goal is to generate unique IDs without any coordination at all. This is what we call coordination-free unique IDs. UUID Enters the Scene Flip a coin 128 times and write down 1 for each head and 0 for each tail. This gives you a sequence of 128 1s and 0s, or 128 bits of randomness. That’s a space large enough that the probability of generating the same sequence twice is so extremely low that you can rule it out for practical purposes. How is that related to UUIDs? If you have ever seen a UUID then you know they look similar to this: 420cd09a-4d56-4749-acc2-40b2e8aa8c42. This format is just a textual representation of 128 bits. How does it work? The UUID string has 36 characters in total. If we remove the 4 dashes, which are there just to make it a bit more human-readable, we are left with 32 hexadecimal digits: 0-F. Each digit represents 4 bits and 32 * 4 bits = 128 bits. So UUIDs are 128-bit values. We often represent them as strings, but that's just a convenience. UUID has been explicitly designed to be unique and generated without coordination. When you have a good random generator, 128 random bits are enough to practically guarantee uniqueness. At the same time, 128 bits are not too much, so UUIDs do not occupy too much space when stored. UUID Versions There are multiple versions of UUIDs. Versions 1-5 are defined in RFC 4122 and they are the most widely used. Versions 6 - 8 are currently in draft status and might be approved in the future. Let's take a brief look at the different versions. Version 1 Version 1 is generated by using a MAC address and time as inputs. The MAC address is used to ensure uniqueness across multiple machines. The time ensures uniqueness across multiple processes on the same machine. Using the MAC means that generated UUIDs can be tracked to a specific machine. This can be useful occasionally, but it might not be desirable in other cases, as a MAC address can be considered private information. Interestingly enough, the time portion is not based on the usual Unix epoch, but it uses a count of 100-nanosecond intervals since 00:000:00.00 on the 15th of October 1582. What is special about October 1582? It's the Gregorian calendar reform. See version 7 for a UUID with a standard Unix epoch. Version 2 Version 2 is similar to version 1 but adds a local domain ID to the UUID. It's not widely used. Versions 3 and 5 These versions use a hash function to generate the UUID. The hash function is seeded with a namespace UUID and a name. The namespace UUID is used to ensure uniqueness across multiple namespaces. The name is used to ensure uniqueness within a namespace. Version 3 uses MD5 as a hash function, while version 5 uses SHA-1. SHA-1 generates 160 bits, so the digest is truncated to 128 bits. Version 4 Version 4 UUID is probably the most popular one. It relies solely on a random generator to generate UUIDs, similar to the coin flip example above. This means that the quality of the random generator is critical. Version 6 Version 6 is similar to Version 1 but has a different ordering of bytes. It encodes the time from the most significant to the least significant. This allows sorting UUIDs correctly by time when you sort just bytes representing the UUIDs. Version 7 Version 7 uses a 48-bit timestamp and random data. Unlike versions 1, 2, or 6, it uses a standard Unix epoch in milliseconds. It also uses a random generator instead of a MAC address. Version 8 Version 8 is meant to be used for experimental and private use. Security Considerations UUIDs are designed to be unique, but they are not designed to be secret. What's the difference? If you generate a UUID then you can assume it's different from any other UUID generated before or after, but you should not treat them as a password or a secret session identifier. This is what RFC 4122 says about this: Do not assume that UUIDs are hard to guess; they should not be used as security capabilities (identifiers whose mere possession grants access), for example. A predictable random number source will exacerbate the situation. UUID in QuestDB UUIDs are popular synthetic IDs because they can be generated without any coordination and do not use too much space. QuestDB users often store UUIDs, but until recently, QuestDB did not have first-class support. Most users stored UUIDs in a string column. It makes sense because as we have seen above UUIDs have a canonical textual representation. Storing UUIDs in a string column is possible, but it's inefficient. Let's do some math: We already know each UUID has 128 bits, that's 16 bytes. The canonical textual representation of UUID has 36 characters. QuestDB uses UTF-16 encoding for strings, so each ASCII character uses 2 bytes. There is also a fixed cost of 4 bytes per string stored. So it takes 36 * 2 + 4 = 76 bytes to store a single UUID which contains just 16 bytes of information! It's not just wasting disk space. QuestDB must read these bytes when evaluating a SQL predicate, joining tables, or calculating an aggregation. Thus storing UUIDs as strings also makes your queries slower! That's why QuestDB 6.7 implemented UUID as a first-class data type. This allows user applications to declare a column as UUID and then each UUID stored will use only 16 bytes. Thanks to this, SQL queries will be faster. Demo time The demo creates tables occupying just under 100 GB of disk space. Make sure you have enough disk space available. You might also need to increase the query timeout via the query.timeout.sec property. See Configuration for more details. Alternatively, you can change the long_sequence() function to create a smaller number of rows. Let’s create a table with a single string column and populate it with 1 billion random UUIDs. The column is defined as the string type, so the UUIDs will be stored as strings. SQL CREATE TABLE tab_s (s string); INSERT INTO tab_s SELECT rnd_uuid4() FROM long_sequence(1000000000); Let’s try to query it: SQL SELECT * FROM tab_s WHERE s = 'ab632aba-be36-43e5-a4a0-4895e9cd3f0d'; It’s taking around 2.2s. It’s not terrible given it’s a full-table scan over one billion strings, but we can do better! How much better? Let’s see. Create a new table with a UUID column: SQL CREATE TABLE tab_u (u uuid); Populate it with UUID values from the first table: SQL INSERT INTO tab_u SELECT * FROM tab_s; The newly created table has the same values as the first table, but the column is defined as UUID instead of string, so it eliminates the waste we discussed above. Let’s see how the predicate performs now: SQL SELECT * FROM tab_u WHERE u = 'ab632aba-be36-43e5-a4a0-4895e9cd3f0d'; This query takes around 380ms on my test box. That’s almost 6x better than the original 2.2 seconds! Speed is the key to any real-time analysis so this is certainly important. Let’s check disk space. The du command shows the space used by each table. First, the table with strings: Shell $ du -h 79G ./default 79G . The table with UUID: Shell $ du -h 15G ./default 15G . Declaring the column as UUID saved 64GB of disk space! Using UUID optimizes query performance and is cost-effective. Last but not least, predicates on UUID values will become even faster in future QuestDB versions as we are looking at how to vectorize them by using the SIMD instructions! Conclusion We use UUIDs to generate globally unique IDs without any coordination. They are 128 bits long so they do not use too much space. This makes them suitable for distributed applications, IoT, cryptocurrencies, or decentralized finance. When your application stores UUIDs, tell your database it’s a UUID, do not store them in a string column. You will save disk space and CPU cycles.
Though the Internet of Things (IoT) has redefined our lives and brought a lot of benefits, it has a large attack surface area and is not safe until it is secure. IoT devices are an easy target for cybercriminals and hackers if not properly secured. You may have serious problems with financial and confidential data being invaded, stolen, or encrypted. It is difficult to spot and discuss risks for organizations, let alone build a comprehensive methodology for dealing with them, without practical knowledge of what IoT security is and testing it. Realizing the security threats and how to avoid them is the first step, as Internet of Things solutions require significantly more testing than before. Integrated security is frequently lacking when it comes to introducing new features and products to the market. What Is IoT Security Testing? IoT security testing is the practice of evaluating cloud-connected devices and networks to reveal security flaws and prevent devices from being hacked and compromised by a third party. The biggest IoT security risks and challenges can be addressed through a focused approach with the most critical IoT vulnerabilities. Most Critical IoT Security Vulnerabilities There are typical issues in security analysis faced by organizations that are missed even by experienced companies. Adequate testing Internet of Things (IoT) security in networks and devices is required, as any hack into the system can bring a business to a standstill, leading to a loss in revenue and customer loyalty. The top ten common vulnerabilities are as follows: 1. Weak Easy-to-Guess Passwords Absurdly simple and short passwords that put personal data at risk are among the primary IoT security risks and vulnerabilities for most cloud-connected devices and their owners. Hackers can co-opt multiple devices with a single guessable password, jeopardizing the entire network. 2. Insecure Ecosystem Interfaces Insufficient encryption and verification of the user’s identity or access rights in the ecosystem architecture, which is software, hardware, network, and interfaces outside of the device, enable the devices and associated components to get infected by malware. Any element in the broad network of connected technologies is a potential source of risk. 3. Insecure Network Services The services running on the device should be given special attention, particularly those that are open to the Internet and have a high risk of illegal remote control. Do not keep ports open, update protocols, and ban any unusual traffic. 4. Outdated Components Outdated software elements or frameworks make a device unprotected from cyberattacks. They enable third parties to interfere with the performance of the gadgets, operating them remotely or expanding the attack surface for the organization. 5. Insecure Data Transfer/Storage The more devices are connected to the network, the higher the level of data storage/exchange should be. A lack of secure encoding in sensitive data, whether it is at rest or transferred, can be a failure for the whole system. 6. Bad Device Management Bad device management happens because of a poor perception of and visibility into the network. Organizations have a bunch of different devices that they do not even know about, which are easy entry points for attackers. IoT developers are simply unprepared in terms of proper planning, implementation, and management tools. 7. Poor Secure Update Mechanism The ability to securely update the software, which is the core of any IoT device, reduces the chances of it being compromised. The gadget becomes vulnerable every time cybercriminals discover a weak point in security. Similarly, if it is not fixed with regular updates, or if there are no regular notifications of security-related changes, it can become compromised over time. 8. Inadequate Privacy Protection Personal information is gathered and stored in larger amounts on IoT devices than on smartphones. In case of improper access, there is always a threat of your information being exposed. It is a major privacy concern because most Internet of Things technologies are somehow related to monitoring and controlling gadgets at home, which can have serious consequences later. 9. Poor Physical Hardening Physical hardening is one of the major aspects of high security IoT devices since they are a cloud computing technology that operates without human intervention. Many of them are intended to be installed in public spaces (instead of private homes). As a result, they are created in a basic manner, with no additional level of physical security. 10. Insecure Default Settings Some IoT devices come with default settings that cannot be modified, or there is a lack of alternatives for operators when it comes to security adjustments. The initial configuration should be modifiable. Default settings that are invariant across multiple devices are insecure. Once guessed, they are used to hack into other devices. How To Protect IoT Systems and Devices Easy-to-use gadgets with little regard for data privacy make IoT security on smart devices tricky.

Web 3.0 is indeed the future version of the present-day Internet which will be purely based on public blockchains. Public blockchains refer to a record-keeping system known for carrying out crypto transactions. Unlike its predecessors, the key feature of Web 3.0 is its decentralized mechanism, translating to users using the Internet via services governed by major tech players, individuals, and users. The users will also get the privilege of controlling various parts of the Internet. Web 3.0 doesn't necessarily demand any form of "permissions," meaning that the governing bodies have no role to play in deciding the Internet service accessibility, nor is any "trust" required. Hence no intermediatory body is not necessary to carry out virtual transactions amongst different involved parties. Since these online agencies are involved in most of the data collection part, Web 3.0 will protect user privacy in a better manner. Decentralized Finance, or DeFi, is an integral component of Web 3.0 and has gained significant traction recently. It involves executing real-world financial transactions over blockchain technology without any assistance from banks or the government. Also, larger enterprises across different industries are now investing in Web 3.0, and this hasn't been easy to consider that their engagement won't be driving results in some centralized authority form. What Is Web 3.0? Web 3.0, also called the Semantic Web or read-write-execute, is the web era starting from 2010 that mentions the future of the web. Technologies like Artificial Intelligence and Machine Learning allow user systems to analyze data the same way as humans, which assists in the smart generation and distribution of important content per the user's needs. There are a lot of differences between Web 2.0 and Web 3.0. with decentralization present at the core of both web versions. Web 3.0 developers do not always create and deploy applications running over a single server, or the data remains stored in just one database (hosted on and managed by a cloud service provider). Rather, applications based on Web 3.0 are developed on blockchains, decentralized networks of multiple servers, or a hybrid of these two (blockchain and servers). These programs are also called Decentralized Apps or DApps. In the Web 3.0 ecosystem, network participants or developers are recognized and awarded for delivering the best services toward creating a stable and secure decentralized network. Benefits of Web 3.0 Over Predecessors Since in Web 3.0, there are no intermediaries involved, there is no longer control over the user data. This also eliminates the possibilities of government/corporate restrictions and damages from denial-of-service or DoS attacks. Compared to the previous web versions, searching for accurately-refined results over search engines has proved challenging. However, search engines have significantly transformed their strengths to discover semantically relevant results based on users' search intent and information. This has made web browsing a more convenient option than before, allowing users to get the specific piece of information they need easily. Customer service has also been important for driving positive user experience on websites and web applications. Leading successful web-driven organizations to find it difficult to upscale their customer operations due to high expenditures. Users can get a better experience while engaging with support teams using AI-driven chatbots that can 'talk' to multiple customers simultaneously, backed by the emergence of Web 3.0 with the use of artificial intelligence and machine learning technologies. Significant Characteristics of Web 3.0 The transition to Web 3.0 is taking place at a very slow pace and might get unnoticed by the general web audience. Web 3.0 applications have a strong resemblance in terms of look and feel with Web 2.0 applications; however, their back end differs fundamentally. The future of Web 3.0 is headed towards universal applications that can be easily read and used by multiple devices and software types, making the end user's commercial activities better with seamless experiences. Decentralization of data and establishment of transparent and secure environments are going to emerge with the advent of next-gen technologies like distributed ledgers and blockchain, which will dissolve Web 2.0's centralized surveillance and bombarded advertisements. In a decentralized web-like Web 3.0, individual users get complete control of their data, where a decentralized infrastructure and application platforms are displacing the centralized tech-based organizations. The following are some major properties of Web 3.0 in order to determine the associated complexities and intricacies linked with this emerging web version. Semantic Web The concept of the Semantic Web is a very critical element of Web 3.0, which was coined by the legend Tim Berners-Lee for describing a web of data that machines can analyze. In layman's language, the syntax of two phrases can differ, by their semantics remain similar, and semantics is more centered around the emotion depicted through facts. A couple of cornerstones are linked with Web 3.0: semantic web and artificial intelligence. The semantic web will help computer systems understand what data means, while AI will assist in creating real-world use cases that can enhance data use. The primary concept is to create a knowledge loop across the Internet that will support understanding the words and then generating, sharing, and connecting content via search and analytics tools. Web 3.0 will boost data communications owing to the semantic metadata. As a result, the user experience gets elevated to higher levels of connectivity, benefiting from the real data that can be easily accessed. Artificial Intelligence Owing to artificial intelligence technology, websites can now filter out and provide the best facts. In the present web era of Web 2.0, enterprises have started soliciting customer feedback for an enhanced understanding of the product or service quality. One of the major contributors to this present-day web is peer reviews. However, these human recommendations and thoughts can get opinionated or biased towards a particular service. Various AI models are now being trained to differentiate between good and bad data and offer suggestions backed with relevant and accurate information. Ubiquitous The ubiquitous characteristic of Web 3.0 is seen as the concept of existing or being present simultaneously; however, this feature is already present in Web 2.0 as well. For instance, on social media platforms where users share their photos and online with everyone online. This makes the sharer the intellectual property owner of the media he has shared. Once it is shared online, the photo becomes available everywhere, making it ubiquitous. With the increased number of mobile devices and Internet penetration across these devices, Web 3.0 remains accessible from anywhere, anytime. Unlike the previous web versions, the Internet won't be restricted to desktops or smartphones. With everything around us getting interconnected in a digital ecosystem called the Internet of Things, Web 3.0 is seen as the web of everything and everywhere. 3D Graphics Web 3.0 will impact the future of the Internet, as there'll be a transition from a two-dimensional web to a more realistic three-dimensional digital world. Services and websites of Web 3.0, like eCommerce, online games, and the real estate markets, are some sectors that will be extensively using three-dimensional designing.
