Tips to Ensure Communication Security for IoT
If companies don't get IoT security rights, hackers could control critical personal, business, or national data, which could be disastrous.
FREMONT, CA: According to Statista research, 75 billion devices get expected to be connected to the internet globally by 2025. However, if such devices aren't secure, they can pose just as much risk as they do opportunity, and entire national infrastructures could be jeopardized, with disastrous consequences.
There are numerous reports of IoT security failures, including video doorbells that stream unencrypted data. These smart plugs allow remote execution of arbitrary code, smart home devices that store unencrypted home Wi-Fi network passwords, industrial control systems that would enable attackers to control machinery remotely, and so on.
Ways to ensure communication security for IoT
Blind faith gets replaced with verification and strong cryptographic guarantees in the zero-trust method. Even if the underlying infrastructure is compromised, the goal is to maintain security, integrity, and privacy. The network has no special status under zero trust and gets treated as the public internet.
Third parties must not determine any data provided across the network, which is a basic need of communications systems, whether they are for personal or industrial applications. From the time it is generated to the time it is transmitted, encrypting all data. Well-vetted and standardized cryptographic primitives with unique key material should be helpful for end-to-end encryption.
Providing these protections by solid cryptographic mechanisms, such as hash-based message authentication, should be employed to maintain data integrity.In addition to maintaining confidentiality, it's essential that an attacker can't tamper with or fabricate messages. Such attempts can be detectable by the network. Furthermore, a recorded message should not be able to be correctly verified by replaying it.
Third parties should not be allowed to determine the identification associated with over-the-air communications or the ability to know whether messages are sent from one device or numerous devices to safeguard privacy.There should be no discernible relationship between messages and devices, preventing what is known as metadata assaults. While vital cryptographic concepts for encryption and data integrity are widely helpful, many systems still convey unencrypted identifying data.
With the ability to join billions of devices, the Internet of Things (IoT) must be scalable to assure not only its long-term success but also its security. Low-cost or low-power gadgets do not excuse inadequate security or privacy. The Internet of Things industry must accommodate exponential growth while providing low-power and low-cost deployment.However, developing forward security measures to distribute upgrades and improvements and address the inevitable security vulnerabilities may arise for devices already in use.
