Differentiated Security

	Differentiated Security Differentiated security is a form of computer security that deploys a range of different security policies and mechanisms according to the identity and context of a user or transaction. This makes it much more difficult to scale or replicate attacks, since each cluster/individual has a different security profile and there should be no common weaknesses. One way of achieving this is by subdividing the population into small differentiated clusters. At the extreme, each individual belongs to a different class.

picture info	Computer Security Computer security, cybersecurity (cyber security), or information technology security (IT security) is the protection of computer systems and networks from attack by malicious actors that may result in unauthorized information disclosure, theft of, or damage to hardware, software, or data, as well as from the disruption or misdirection of the services they provide. The field has become of significance due to the expanded reliance on computer systems, the Internet, and wireless network standards such as Bluetooth and Wi-Fi, and due to the growth of smart devices, including smartphones, televisions, and the various devices that constitute the Internet of things (IoT). Cybersecurity is one of the most significant challenges of the contemporary world, due to both the complexity of information systems and the societies they support. Security is of especially high importance for systems that govern large-scale systems with far-reaching physical effects, such as power distribution, ...

	Policies And Mechanisms The separation of mechanism and policy is a design principle in computer science. It states that mechanisms (those parts of a system implementation that control the authorization of operations and the allocation of resources) should not dictate (or overly restrict) the policies according to which decisions are made about which operations to authorize, and which resources to allocate. While most commonly discussed in the context of security mechanisms (authentication and authorization), separation of mechanism and policy is applicable to a range of resource allocation problems (e.g. CPU scheduling, memory allocation, quality of service) as well as the design of software abstractions. Per Brinch Hansen introduced the concept of separation of policy and mechanism in operating systems in the RC 4000 multiprogramming system. Artsy and Livny, in a 1987 paper, discussed an approach for an operating system design having an "extreme separation of mechanism and policy". In a 2000 article, ...

	Differentiated Service (design Pattern) {{for, the network traffic classification system, Differentiated services Differentiated service is a design pattern for business services and software, in which the service varies automatically according to the identity of the consumer and/or the context in which the service is used. Sometimes known as smart service or context-aware service. Concept Differentiated service is extensively covered in a few narrow technical areas, such as telecoms networks and internet (see Differentiated services). It is also mentioned in some marketing sources, with reference to customer segmentation. But the general principle of service differentiation extends far beyond these domains, and it is one of the mechanisms for implementing flexibility in a service-oriented architecture (SOA). Various dimensions of the service can be differentiated, including: Information quality. For example, an information service providing stock prices may offer real-time prices to selected users, and 15-minute-delay ...

	Separation Of Protection And Security In computer sciences, the separation of protection and security is a design choice. Wulf et al. identified protection as a mechanism and security as a policy,Wulf 74 pp.337-345 therefore making the protection-security distinction a particular case of the separation of mechanism and policy principle. Many frameworks consider both as security controls of varying types. For example, protection mechanisms would be considered technical controls, while a policy would be considered an administrative control. Overview The adoption of this distinction in a computer architecture usually means that protection is provided as a fault tolerance mechanism by hardware/firmware and kernel, whereas the operating system and applications implement their security policies. In this design, security policies rely therefore on the protection mechanisms and on additional cryptography techniques. The major hardware approachSwift 2005 p.26 for security or protection is the use of hierarchical protection ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu]
