Security Convergence
Security convergence refers to the convergence of two historically distinct security functions – physical security and information security – within enterprises; both are integral parts of a coherent risk management program. Security convergence is motivated by the recognition that corporate assets are increasingly information-based. In the past, physical assets demanded the bulk of protection efforts, whereas information assets are demanding increasing attention. Although generally used in relation to cyber-physical convergence, security convergence can also refer to the convergence of security with related risk and resilience disciplines, including business continuity planning and emergency management. Security convergence is often referred to as 'converged security'. Definitions According to the United States Cybersecurity and Infrastructure Security Agency, security convergence is the "formal collaboration between previously disjointed security functions."

Physical Security
Physical security describes security measures that are designed to deny unauthorized access to facilities, equipment and resources and to protect personnel and property from damage or harm (such as espionage, theft, or terrorist attacks). Physical security involves the use of multiple layers of interdependent systems that can include CCTV surveillance, security guards, protective barriers, locks, access control, perimeter intrusion detection, deterrent systems, fire protection, and other systems designed to protect persons and property. Overview Physical security systems for protected facilities are generally intended to: * deter potential intruders (e.g. warning signs, security lighting and perimeter markings); * detect intrusions and monitor/record intruders (e.g. intruder alarms and CCTV systems); and * trigger appropriate incident responses (e.g. by security guards and police). It is up to security designers, architects and analysts to balance security controls against ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Security
" \n\n\nsecurity.txt is a proposed standard for websites' security information that is meant to allow security researchers to easily report security vulnerabilities. The standard prescribes a text file called \"security.txt\" in the well known location, similar in syntax to robots.txt but intended to be machine- and human-readable, for those wishing to contact a website's owner about security issues. security.txt files have been adopted by Google, GitHub, LinkedIn, and Facebook.\n History \n\nThe Internet Draft was first submitted by Edwin Foudil in September 2017. At that time it covered four directives, \"Contact\", \"Encryption\", \"Disclosure\" and \"Acknowledgement\". Foudil expected to add further directives based on feedback. In addition, web security expert Scott Helme said he had seen positive feedback from the security community while use among the top 1 million websites was \"as low as expected right now\".\n\nIn 2019, the Cybersecurity and Infrastructure Security Agenc ...

System Of Systems
System of systems is a collection of task-oriented or dedicated systems that pool their resources and capabilities together to create a new, more complex system which offers more functionality and performance than simply the sum of the constituent systems. Currently, systems of systems is a critical research discipline for which frames of reference, thought processes, quantitative analysis, tools, and design methods are incomplete. The methodology for defining, abstracting, modeling, and analyzing system of systems problems is typically referred to as system of systems engineering. Overview Commonly proposed descriptions—not necessarily definitions—of systems of systems, are outlined below in order of their appearance in the literature: # Linking systems into joint system of systems allows for the interoperability and synergism of Command, Control, Computers, Communications and Information (C4I) and Intelligence, Surveillance and Reconnaissance (ISR) Systems: ''description i ...

Jay Wright Forrester
Jay Wright Forrester (July 14, 1918 – November 16, 2016) was a pioneering American computer engineer and systems scientist. He is credited with being one of the inventors of magnetic core memory, the predominant form of random-access computer memory during the most explosive years of digital computer development (between 1955 and 1975). It was part of a family of related technologies which bridged the gap between vacuum tubes and semiconductors by exploiting the magnetic properties of materials to perform switching and amplification. He is also believed to have created the first animation in the history of computer graphics, a "jumping ball" on an oscilloscope. Later, he was a professor at the MIT Sloan School of Management, where he introduced the Forrester effect describing fluctuations in supply chains, and is credited as the founder of system dynamics, which deals with the simulation of interactions between objects in dynamic systems and is most often applied to r ...
