From the very beginning security of operational technology has relied almost entirely on the standalone nature of OT installations, security by obscurity. At least since 2005 OT systems have become linked to IT systems with the corporate goal of widening an organization's ability to monitor and adjust its OT systems, which has introduced ...
Control system security, or automation and control system (ACS) cybersecurity, is the prevention of (intentional or unintentional) interference with the proper operation of industrial automation and control systems. These control systems manage essential services including electricity, petroleum production, water, transportation, manufacturing ...
IEC 62443 is a series of standards that address security for operational technology in automation and control systems. The series is divided into different sections and describes both technical and process-related aspects of automation and control systems security.
In cryptography, an oblivious transfer (OT) protocol is a type of protocol in which a sender transfers one of potentially many pieces of information to a receiver, but remains oblivious as to what piece (if any) has been transferred. The first form of oblivious transfer was introduced in 1981 by Michael O. Rabin. [1]
System security always a concern for any technology, and it is more crucial for SIoT as not only security of oneself need to be considered but also the mutual trust mechanism between collaborative IoT devices from time to time, from place to place. [169] Another critical challenge for SIoT is the accuracy and reliability of the sensors.
Security as a service : These security services often include authentication, anti-virus, anti-malware/spyware, intrusion detection, penetration testing and security event management, among others. In practice many products in this area will have a mix of these functions, so there will often be some overlap – and many commercial vendors also ...

Multiple Independent Levels of Security/Safety (MILS) is a high-assurance security architecture based on the concepts of separation [1] and controlled information flow. It is implemented by separation mechanisms that support both untrusted and trustworthy components; ensuring that the total security solution is non-bypassable, evaluatable, always invoked, and tamperproof.
