Network security are security controls, 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 ...
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.
Network access control (NAC) is an approach to computer security that attempts to unify endpoint security technology (such as antivirus, host intrusion prevention, and vulnerability assessment), user or system authentication and network security enforcement.
An air gapped network (right) with no connection to a nearby internet-connected network (left) An air gap, air wall, air gapping [1] or disconnected network is a network security measure employed on one or more computers to ensure that a secure computer network is physically isolated from unsecured networks, such as the public Internet or an unsecured local area network. [2]
No single qualification exists to become a security engineer. However, an undergraduate and/or graduate degree, often in computer science, computer engineering, or physical protection focused degrees such as Security Science, in combination with practical work experience (systems, network engineering, software development, physical protection system modelling etc.) most qualifies an individual ...
In computer security, an access-control list (ACL) is a list of permissions [a] associated with a system resource (object or facility). An ACL specifies which users or system processes are granted access to resources, as well as what operations are allowed on given resources. [ 1 ]
For example, it would take a tremendous amount of effort to "kerberize" an existing distributed application. Toward the goal of "secure network programming for the masses", the inventors of SNP conceived secure sockets as a high-level abstraction suitable for securing Internet applications. In 1993, they designed and built a prototype of SNP.
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 can lead to unauthorized information disclosure, theft or damage to hardware, software, or data ...
