Internet of Things (IoT) Security Technologies

Spread the love

Whether because of government regulation or good old-fashioned self-interest, we can expect increased investment in IoT security technologies.

Here is a list of the six technologies for IoT security

IoT network security

Protecting and securing the network connecting IoT devices to back-end systems on the internet. IoT network security is a bit more challenging than traditional network security because there is a wider range of communication protocols, standards, and device capabilities, all of which pose significant issues and increased complexity. Key capabilities include traditional endpoint security features such as antivirus and antimalware as well as other features such as firewalls and intrusion prevention and detection systems. Sample vendors: Bayshore Networks, Cisco, Darktrace, and Scenario.

IoT authentication

Providing the ability for users to authenticate an IoT device, including managing multiple users of a single device (such as a connected car), ranging from simple static password/pins to more robust authentication mechanisms such as two-factor authentication, digital certificates, and biometrics. Unlike most enterprise networks where the authentication processes involve a human being entering a credential, many IoT authentication scenarios are machine-to-machine based without any human intervention. Sample vendors: Baimos Technologies, Covisint, Device Authority, Entrust Datacard, and Gemalto.

IoT encryption

Encrypting data at rest and in transit between IoT edge devices and back-end systems using standard cryptographic algorithms, helping maintain data integrity and preventing data sniffing by hackers. The wide range of IoT devices and hardware profiles limits the ability to have standard encryption processes and protocols. Moreover, all IoT encryption must be accompanied by equivalent full encryption key lifecycle management processes, since poor key management will reduce overall security. Sample vendors: Cisco, Entrust Datacard, Gemalto, HPE, Lynx Software Technologies, and Symantec.


Providing complete X.509 digital certificate and cryptographic key and life-cycle capabilities, including public/private key generation, distribution, management, and revocation. The hardware specs for some IoT devices may limit or prevent their ability to utilize PKI. Digital certificates can be securely loaded onto IoT devices at the time of manufacture and then activated/enabled by third-party PKI software suites; the certificates could also be installed post-manufacture. Sample vendors: DigiCert, Entrust Datacard, Gemalto, HPE, Symantec, and WISeKey.

IoT security analytics

Collecting, aggregating, monitoring, and normalizing data from IoT devices and providing actionable reporting and alerting on specific activities or when activities fall outside established policies. These solutions are starting to add sophisticated machine learning, artificial intelligence, and big data techniques to provide more predictive modeling and anomaly detection (and reduce the number of false positives), but these capabilities are still emerging. IoT security analytics will increasingly be required to detect IoT-specific attacks and intrusions that are not identified by traditional network security solutions such as firewalls. Sample vendors: Cisco, Indegy, Kaspersky Lab, SAP, and Senrio.

IoT API security

Providing the ability to authenticate and authorize data movement between IoT devices, back-end systems, and applications using documented REST-based APIs. API security will be essential for protecting the integrity of data transiting between edge devices and back-end systems to ensure that only authorized devices, developers, and apps are communicating with APIs as well as detecting potential threats and attacks against specific APIs. Sample vendors: Akana, Apigee/Google, Axway, CA Technologies, Mashery/TIBCO, MuleSoft, and WS02.
