Secure by default. Security by default, in software, means that the default configuration settings are the most secure settings possible, which are not necessarily the most user-friendly settings. In many cases, security and user-friendliness are evaluated based on both risk analysis and usability tests. This leads to the discussion of what the ...
v. t. e. In IEEE 802 LAN/MAN standards, the medium access control ( MAC ), also called media access control, is the layer that controls the hardware responsible for interaction with the wired (electrical or optical) or wireless transmission medium. The MAC sublayer and the logical link control (LLC) sublayer together make up the data link layer.
Security testing. Security testing is a process intended to detect flaws in the security mechanisms of an information system and as such help enable it to protect data and maintain functionality as intended. [1] Due to the logical limitations of security testing, passing the security testing process is not an indication that no flaws exist or ...
Access control matrix. In computer science, an access control matrix or access matrix is an abstract, formal security model of protection state in computer systems, that characterizes the rights of each subject with respect to every object in the system. It was first introduced by Butler W. Lampson in 1971. [1]
Application firewall. An application firewall is a form of firewall that controls input/output or system calls of an application or service. It operates by monitoring and blocking communications based on a configured policy, generally with predefined rule sets to choose from. The two primary categories of application firewalls are network-based ...
Context-based access control. Context-based access control ( CBAC) is a feature of firewall software, which intelligently filters TCP and UDP packets based on application layer protocol session information. It can be used for intranets, extranets and internets. [1]
Data-centric security. Data-centric security is an approach to security that emphasizes the dependability of the data itself rather than the security of networks, servers, or applications. Data-centric security is evolving rapidly as enterprises increasingly rely on digital information to run their business and big data projects become mainstream.
Network security consists of the policies, processes and practices adopted to prevent, detect and monitor unauthorized access, misuse, modification, or denial of a computer network and network-accessible resources. [1] Network security involves the authorization of access to data in a network, which is controlled by the network administrator.
