Cyber–physical system. Cyber-Physical Systems (CPS) are control systems that integrate computation and physical processes, with embedded computers and networks monitoring and controlling physical systems in real-time. [ 1 ] In cyber-physical systems, physical and software components are deeply intertwined, able to operate on different spatial ...
An example of a physical security measure: a metal lock on the back of a personal computer to prevent hardware tampering. Computer security (also cybersecurity, digital security, or information technology (IT) security) is the protection of computer software, systems and networks from threats that may result in unauthorized information disclosure, theft of (or damage to) hardware, software, or ...

Physical security – protecting property and people from damage or harm (such as from theft, espionage, or terrorist attacks). It includes security measures designed to deny unauthorized access to facilities, (such as a computer room), equipment (such as your computer), and resources (like the data storage devices, and data, in your computer).
Physical information security is the intersection or common ground between physical security and information security.It primarily concerns the protection of tangible information-related assets such as computer systems and storage media against physical, real-world threats such as unauthorized physical access, theft, fire and flood.
Firewall (computing) In computing, a firewall is a network security system that monitors and controls incoming and outgoing network traffic based on predetermined security rules. [1][2] A firewall typically establishes a barrier between a trusted network and an untrusted network, such as the Internet. [3]
