KasperskyOS is a secure-by-design operating system designed for network devices, industrial control systems and the Internet of Things. The operating system is not made for your average home PC; instead, it is meant to protect industrial systems and embedded devices from cyber attacks by preventing any third-party or malicious code from executing. The OS also has independent security engine that lets users enforce the policy that suits their security objectives. The new OS has been designed to allow programs to execute only documented operations under its strict security policy. Only what is defined by the policy can be executed.
