From smart thermostats and grocery store checkouts to public utility infrastructures and industrial manufacturing lines, the Internet of Things (IoT) is all around us—and growing larger every day. But with this rapid growth comes a number of operational challenges: IoT devices collect a large amount of data, and are often distributed across harsh, ever-changing environments. When running IoT infrastructures at high scale, monitoring device fleets that consist of multiple hardware models, processing architectures, networking configurations, and operating systems becomes an increasingly complex task.
Today, we’re excited to announce a preview release of a Datadog Agent designed for IoT devices and embedded applications. The IoT Agent is a lightweight version of the standard Datadog Agent that takes up fewer resources while still providing full visibility into your devices by automatically collecting over 100 health metrics and application logs. Using the IoT Agent, you can monitor all of your IoT devices within a single, unified platform, helping you optimize performance, rapidly resolve issues, and improve customer satisfaction.
To meet the demands of diverse industries and use cases, the Datadog IoT Agent can be installed on the most popular IoT operating systems and hardware architectures (including x86 and Armv7/v8 processors) with a single command. Once you’ve installed the Agent, you can analyze the metrics it collects, set up alerts, and use your findings to address any issues discovered. And by adding tags to your devices and metrics based on categories like location and device version, you can easily sort your fleet to view and compare the performances of the devices you want to focus on.
When managing an IoT device fleet, it’s imperative that operators can easily monitor the information that is most relevant to their use case. With Datadog, you can create custom dashboards that display essential metrics—such as network throughput, disk usage, and more—across your entire device fleet so that you can see at a glance the state of your IoT infrastructure. For instance, in a retail setting, you might want to monitor all of the points of service in a large department store: with a few clicks, you can track those devices from a single dashboard. Then, you can use tags to filter your graphs and drill down to specific groups or even individual devices.
You can also define and collect custom metrics, letting you visualize and alert on the key data that is most important to your IoT fleet. For example, when monitoring retail points of service, you can collect metrics on transaction time, number of failed transactions, and more.
Like the standard Datadog Agent, the IoT Agent collects logs from all of your devices so that you can dive deep into a faulty device’s performance as soon as a problem is caught. Datadog’s Log Explorer provides a centralized view from which to troubleshoot device performance. You can easily filter and analyze all of your logs in real time, so that finding the logs that you need to fix your issue is a seamless process.

Everything around us has become smart, like smart infrastructures, smart cities, autonomous vehicles, to name a few. The innovation of smart devices makes it possible to achieve these heights in science and technology. But, data is vulnerable, there is a risk of attack by cybercriminals. To get started, let’s know about IoT devices.
The Internet Of Things(IoT) is a system that interrelates computer devices like sensors, software, and actuators, digital machines, etc. They are linked together with particular objects that work through the internet and transfer data over devices without humans interference.
Famous examples are Amazon Alexa, Apple SIRI, Interconnected baby monitors, video doorbells, and smart thermostats.
When technologies grow and evolve, risks are also on the high stakes. Ransomware attacks are on the continuous increase; securing data has become the top priority.
When you think your smart home won’t fudge a thing against cybercriminals, you should also know that they are vulnerable. When cybercriminals access our smart voice speakers like Amazon Alexa or Apple Siri, it becomes easy for them to steal your data.
Cybersecurity report 2020 says popular hacking forums expose 770 million email addresses and 21 million unique passwords, 620 million accounts have been compromised from 16 hacked websites.
The attacks are likely to increase every year. To help you secure your data of IoT devices, here are some best tips you can implement.
Your router has the default name of make and model. When we stick with the manufacturer name, attackers can quickly identify our make and model. So give the router name different from your addresses, without giving away personal information.
If your devices are connected to the internet, these connections are vulnerable to cyber attacks when your devices don’t have the proper security. Almost every web interface is equipped with multiple devices, so it’s hard to track the device. But, it’s crucial to stay aware of them.
When we use the default usernames and passwords, it is attackable. Because the cybercriminals possibly know the default passwords come with IoT devices. So use strong passwords to access our IoT devices.
Use strong or unique passwords that are easily assumed, such as ‘123456’ or ‘password1234’ to protect your accounts. Give strong and complex passwords formed by combinations of alphabets, numeric, and not easily bypassed symbols.
Also, change passwords for multiple accounts and change them regularly to avoid attacks. We can also set several attempts to wrong passwords to set locking the account to safeguard from the hackers.
Are you try to keep an eye on your IoT devices through your mobile devices in different locations. I recommend you not to use the public WI-FI network to access them. Because they are easily accessible through for everyone, you are still in a hurry to access, use VPN that gives them protection against cyber-attacks, giving them privacy and security features, for example, using Express VPN.
There are software and firewalls like intrusion detection system/intrusion prevention system in the market. This will be useful to screen and analyze the wire traffic of a network. You can identify the security weakness by the firewall scanners within the network structure. Use these firewalls to get rid of unwanted security issues and vulnerabilities.
Every smart device comes with the insecure default settings, and sometimes we are not able to change these default settings configurations. These conditions need to be assessed and need to reconfigure the default settings.
Nowadays, every smart app offers authentication to secure the accounts. There are many types of authentication methods like single-factor authentication, two-step authentication, and multi-factor authentication. Use any one of these to send a one time password (OTP) to verify the user who logs in the smart device to keep our accounts from falling into the wrong hands.
Every smart device manufacturer releases updates to fix bugs in their software. These security patches help us to improve our protection of the device. Also, update the software on the smartphone, which we are used to monitoring the IoT devices to avoid vulnerabilities.
When we connect the smart home to the smartphone and control them via smartphone, you need to keep them safe. If you miss the phone almost, every personal information is at risk to the cybercriminals. But sometimes it happens by accident, makes sure that you can clear all the data remotely.
However, securing smart devices is essential in the world of data. There are still cybercriminals bypassing the securities. So make sure to do the safety measures to avoid our accounts falling out into the wrong hands. I hope these steps will help you all to secure your IoT devices.
