The recent announcement that the US Federal government has re-introduced an act to improve IoT cybersecurity has focused everyone’s attention on the issue. Although IoT is a prime victim of cyberattacks, many IoT device manufacturers emphasize connectivity and functionality over security in their products.

Things are, however, beginning to shift. The re-emergence of Mirai, a malware that attacks smart devices, uses ARC processors to run and turns them into a network of bots that can be controlled remotely. This has highlighted the importance of protecting the IoT devices and current concerns about how easily the Triton malware entered IoT devices.

As a result, there have been many efforts to safeguard IoT networks. Some argue that combining AI with Blockchain technology could fix the problem. However, blockchain suffers from scaling challenges, making it an ineffective option for securing large IoT networks.

SSL certificates are now the most popular security solution among IoT companies. According to experts, SSL certificates are the best security solutions that you can find for IoT networks, and it has been around for several years. SSL certificates must be purchased from a reputable SSL provider that provides the highest level of protection.

Some Common Threats Faced by IoT Network


Botnets are groups of internet-connected devices used to steal data, corrupt networks, and send spam messages/emails. They are a type of malware that enables hackers to access an IoT device and its connection to enter a company’s network, making them one of the most dangerous threats to businesses.

They are especially noticeable in appliances that were not built to be secure from the start. These gadgets are always changing and evolving. It is vital to keep an eye on their changes and threat behaviours to avert attacks.


AI-Based Attacks

While artificial intelligence (AI) attacks have been quite common in the past 15 years, their vulnerabilities to IoT networks are becoming more prevalent. To execute their attacks, hackers are now creating AI-powered programs that are quicker, easier to scale, and more effective than humans.

This is a significant threat to the IoT ecosystem. While the techniques and features of traditional IoT risks posed by cyber attackers appear to be the same, the scale, automation, and personalization of AI-based attacks will make them harder to combat.

Weak Passcodes

While complex passcodes can provide safety for most IoT devices, one weak passcode is more than enough to access your company’s network. Hackers can attack your entire corporate network because of the inconsistent handling of passcodes across the office.

A password-oriented attack becomes more likely to occur if one person fails to follow advanced password management practices. It is critical to maintaining proper password hygiene to guarantee that your company adheres to best industry practices in terms of security.

SSL Certificates and IoT Devices

For ensuring authenticity, security, and website integrity, SSL certificates are frequently used. Also, as you know, SSL certificates help secure IoT networks. That is why IoT device certificates are in great demand these days. There are several kinds of SSL certificates, but they all work the same way.

Asymmetric encryption is used by the SSL protocol to safeguard data and information shared between two IoT devices. In the most common scenario, a website will deliver an SSL certificate to the user’s browser, and a trustworthy supplier will have signed it.

Given a big key size, the mathematics of the protocol makes these SSL certificates tough to falsify, giving users confidence that the site they are connected to is authentic. SSL certificates can be utilized for a variety of purposes.

Big corporations frequently use them to verify clients or grant certain workers safe access to databases or files. They are also utilized to secure emails. This method can also be used to ensure that IoT devices are authentic. In three ways, this increases IoT device security. Let us look.

  • A globally trusted SSL certificate can be issued to an IoT device, allowing clients to access it the same way they would with a secure website. Since this SSL certificate is likewise globally trusted, users will not be prompted by a security warning or be required to add a self-signed certificate exemption to their device.
  • An IoT device may require a client certificate from the user’s smartphone for conducting specific functions. This is typical in ‘smart locks,’ which require an SSL certificate from the user’s smartphone to open the door.
  • Finally, regardless of the type of SSL certification used, the connection between two IoT devices is secured only after these certificates are transferred. When there is a cyberattack, this prevents sensitive information, including passwords, from being captured and read.

What Are IoT SSL Certificates and What Do They Mean?

The number of smart devices is increasing each day, and it is more critical than ever to have a trustworthy data security solution. An API connects every IoT device to the system. It is a method of transferring data between multiple platforms that makes it easier.

Even though smart devices are synced with web applications, this is essential for application based IoT devices and sensors. SSL certificates for IoT devices enable encrypted data transmission. If a cyber-criminal tries to hack it, all he gets is garbled code. Hackers cannot see the encrypted data since it is concealed.

You will need a more robust security solution when you already have a large data stream to manage from multiple IoT devices. As per the IDC report, there will be around 57 million IoT devices by 2025, with IoT platforms accounting for more than 75 % of them. Furthermore, by 2025, the utilization of smart devices will have increased to 73.1 zettabytes.

Managing Big Data and ensuring that no data breaches or hacking occur throughout the data transfer is essential. Such safety can be ensured with better encryption. You will need SSL certificates with a high-quality encryption method to protect your data.

How Does an IoT SSL Certificate Work?

IoT SSL Certificates encrypt data and change it into gibberish so that no cyber-criminal can decipher it. It sets up encryption between the IoT device and the app. Furthermore, an SSL Certificate encrypts the data to avoid interception throughout the transfer. As a result, the information will not be readable even if captured.

Data access authentication is another crucial feature. SSL Certificates provide an extra layer of security by allowing users to validate their identities. Most IoT devices use a LAN. Hackers can easily break into such networks. Network assaults expose Wi-Fi connection vulnerabilities, resulting in data packet theft. The encryption-decryption technique used by IoT SSL Certificate verifies user devices for accessing data.

All data packets are encrypted using a public key, which can only be decoded using the same safety key given to the user. Safety keys, like private or public keys, are used based on the encryption type provided by an SSL certificate. Asymmetric encryption and symmetric encryption are the two types of encryptions.

The security keys will be different in asymmetric encryption for encryption and decryption. However, in symmetric encryption, the encryption and decryption security keys will be the same.

This type of coding is possible with SSL certificates thanks to cryptographic algorithms, and that is why you must choose the safest SSL certificate for your IoT network. Several SSL certificates are suited for IoT devices, such as wildcard SSL certificates, single domain, and multi-domain SSL certificates, which are highly recommended.

SSL Certificate Ensures Data Integrity

For ensuring high data integrity, businesses require safe and secure systems. An SSL Certificate allows every employee to authenticate data access, ensuring higher data integrity while safeguarding your system. Using multi-factor authentication in conjunction with SSL is another technique to improve data security. The employee’s device receives the private key needed for the decryption of data.

SSL Certificate Ensures Data Encryption

SSL protects data during transmission by encrypting data packets. As a result, with their services embedded in IoT devices, they can encrypt data packets before sending them to and from the devices, securing the data transported to and from the devices. Even if the data is taken, it will never be decrypted.

SSL Certificate Ensures Data Authentication

SSL also verifies the identity of the devices that communicate with one another. Furthermore, because IoT devices frequently communicate with one another, they lack the security necessary for proper device authentication.

As a result, fraudsters may take advantage of it by impersonating the device and obtaining your personal information. The IoT SSL certificate fixes the problem by adding a trustworthy, unbeatable component to each device.

Some Additional Benefits of IoT SSL Certificates

SSL certificates are a great method to keep your data safe and allow IoT devices to be authenticated with confidence. However, these are only a few benefits that using IoT SSL certificates can provide.

IoT SSL Certificates offer numerous benefits, provide unique identification, and boost data integrity through encryption. Let us look at them.

  • IoT SSL certificates provide greater scalability and flexibility because they can be deployed on any device, regardless of its type. Furthermore, no passwords, tokens, or security tools are required.
  • Every certificate can be revoked and substituted, giving you full control over your IoT device. A certificate management system makes it easy to install and control the certificate.
  • It is quite cost-effective, particularly if you transfer a large amount of data.
