Securing IoT devices and applications is not just about protecting the data stored on the device. It also includes security solutions for the firmware and software used on the device. For example, a newer technology called Trusted Platform Module (TPM) offers an additional layer of security by allowing the user to configure encryption and mTLS, as well as DNS filtering for privacy and authentication.
mTLS
One of the latest trend in security is mTLS. It is a cryptographically secure method of authentication that can be used to prevent various kinds of attacks.
This type of authentication is ideal for IoT devices, also for mobile phones and laptops. It prevents attackers from reading the memory of these devices, and helps prevent spoofing attacks.
mTLS is also useful for Zero Trust networks. Since most of these devices don’t use logins, mTLS is a good way to ensure a secure connection.
There are several mTLS providers. These providers have their own PKI to provide you with a more secure communication experience. However, it’s difficult to get this right.
Unlike other encryption methods, mTLS is not a foolproof means of preventing brute force attacks. In fact, there are many potential vulnerabilities. For example, it is easy to compromise a credential.
If you want to implement mTLS, you’ll need a “root” TLS certificate. This can be obtained from a trusted certificate authority. Usually, organizations implement mTLS by establishing their own certificate authority. Using a CA to verify your server’s identity is also a good idea.
MTLS can also protect against on-path attacks. An on-path attacker is one who intercepts a communication between a client and server. When mTLS is used, the attacker cannot certify with the client or the server.
Considering the popularity of mTLS, it’s no wonder that some organizations are considering adopting it. Whether you’re running a small enterprise or a large corporation, it’s important to secure your network and your data. By using mTLS, you can reduce the risk of hacking and prevent credential stuffing.
As more and more devices join the network, it becomes increasingly important to secure your information and your infrastructure. Keeping your data and your clients’ data safe is a top priority.
Encryption
Using encryption is a great way to ensure the security of your IoT device. When data is encrypted, it cannot be viewed by unauthorized users. Whether it’s sending data over the Internet, or storing it on a server, encryption is essential. Keeping your data protected helps build trust with your users.
The risk of a data breach in your IoT system can grow with the increasing number of connected devices. With all the personal information being collected and stored, it’s important to protect your data. Aside from encrypting it, there are other measures that you can take.
For example, you can create a unique identity for your IoT device. This can be done with a digital certificate. You can also use asymmetric cryptography to generate public and private key pairs. These keys are then stored in the Hardware Security Module (HSM) to ensure that they are protected.
You can also add a layer of security by installing a Trusted Platform Module (TPM) chip. These chips provide hardware-based encryption and crypto-processing. They also offer strong protection against private keys.
Using a layered cybersecurity architecture can help improve the overall security of your IoT system. It focuses on data integrity, access methods, and reliable identification.
Data points should be protected from the moment they’re created. Encryption and privacy regulations are also important to ensure that you’re not sharing sensitive information.
While many IoT devices have weak credentials, it’s not impossible to improve your security. One option is to implement a PKI program. PKI programs allow organizations to define the cryptographic system they want to use. Another option is to use pre-embedded cryptographic keys. Pre-embedded keys make IoT devices more trustworthy.
DNS filtering
A properly configured DNS system is essential to defending your network against threats. It is the connection point between your users’ browsers and the Internet. Without it, phishing websites can take hold of your credentials.
In addition, DNS filtering can protect your company network from data breaches. It is an effective tool that prevents hackers from stealing your company’s data and other important information. Moreover, it helps in preventing spyware, ransomware, and other malicious links from accessing your network.
IoT devices are increasingly a target of cyber attackers. These devices usually have limited resources and therefore are susceptible to attacks. Some devices are even prone to infections by malware.
The best defense against a DDoS attack is to install DNS filtering technology. This will allow you to effectively screen all IoT devices on your network. Furthermore, it can also help you identify data exfiltration activity.
Besides detecting malware, DNS filtering can also prevent phishing attacks. Cyber attackers will often create fake phishing websites to lure victims into clicking on a link.
However, not all phishing sites are created equal. For instance, some malicious websites offer inappropriate viewing or ads. So, it is important to understand what you’re getting into.
Additionally, it’s essential to ensure that your network is secure in the face of a growing number of connected devices. To do that, you’ll need to implement an intelligent DNS recursive infrastructure.
Using an automated solution can streamline your breach response and help your employees do their jobs. On top of that, it can help you gather crucial security metrics and make well-informed decisions.
Although it may seem like a complex task, DNS filtering is actually relatively simple to implement. Most solutions provide easy, network-wide setup in minutes. Moreover, they are fairly inexpensive.
Retrofitting legacy devices with smart sensors
The Internet of Things is changing the way companies operate. In the industrial setting, IoT-enabled sensors allow equipment to gather information about temperature, vibration, performance, and more. This data can be used to enhance product quality, detect anomalies, and even prevent problems. It also helps companies improve efficiency and reduce costs.
Getting started with IoT is often easy, thanks to intelligent gateways. They help you connect your legacy assets to the cloud. These can also help you identify and resolve issues with other factory units. You may have to upgrade your equipment for enhanced functionality, but the cost is a lot less than it used to be.
For many years, manufacturers have relied on serial-based interfaces to connect their machines. However, they are no longer the most popular. Instead, they are starting to use smart, low-cost IoT sensors.
These low-cost sensors can be quickly deployed on the plant floor. They can read analog gauges, perform predictive maintenance, and generate meaningful data. Companies can then sell the generated data to third party developers.
Industrial IoT is a new technology that uses powerful computing hardware to connect machinery to the Internet. This can automate processes in ways that were impossible a decade ago. A manufacturer can save on energy costs, improve machine health, and gain insights into the quality of its products.
One of the main advantages of digital retrofitting is that it can help companies improve the uptime of their machines. In the past, it has been necessary to conduct expensive upgrades to keep legacy manufacturing systems up to date. Today, there are retrofit kits that can be installed on old machines and connected through wireless networks or wired networks.
Trusted platform module (TPM) technology
Trusted Platform Module (TPM) technology is a security feature in billions of devices. It enables the creation of cryptographic keys and other important device security functions. But TPMs can be a bit confusing. If you’re not familiar with the term, you might be surprised to learn that there are several versions of the module, each with their own unique advantages and disadvantages.
The first version of the trusted platform module, known as TPM 1.1b, offered basic keygen and encryption capabilities. In addition to that, TPM 1.1b also included device health attestation, as well as dictionary attack protection.
The next version, called TPM 2.0, made improvements to both of the above features. Specifically, TPM 2.0 added algorithm interchangeability, as well as support for biometrics.
While the most important TPM feature is undoubtedly the creation of a secure cryptographic key, there are plenty of other features. These include a digital signature, which is a good indication that the device is operating correctly.
Another TPM feature is the ability to generate random numbers. This is important to device security, because it can help prevent unauthorized users from accessing sensitive information.
A TPM can also be used to secure a variety of other features, such as secure storage and boot. This is especially useful for devices that have a large IoT footprint. For example, many cloud security applications rely on TPMs to ensure that they don’t get hacked.
Despite the advantages of the TPM, however, it’s not without its weaknesses. It’s important to use it in conjunction with other security procedures, such as antivirus software. Also, if a hacker gets access to an early boot code, the device is vulnerable.
