A network security policy (NSP) is a generic document that outlines rules for computer network access, determines how policies are enforced and lays out some of the basic architecture of the company security/ network security environment. [1] The document itself is usually several pages long and written by a committee.
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 ...
When the session expires, a re-authentication process is required for the PaC to regain network access. EP (Enforcement Point) It works as a filter of the packets which source is an authenticated PaC. Basically, an EP is a network node which drops packets according to some parameters provided as results of the authentication processes.
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.
Security requirements are applicable to the information sent over the network. The discipline dealing with security over a network is called Network security. [11] The X.800 Recommendation: [1] provides a general description of security services and related mechanisms, which may be provided by the Reference Model; and; defines the positions ...
Temporal Key Integrity Protocol (TKIP / t iː ˈ k ɪ p /) is a security protocol used in the IEEE 802.11 wireless networking standard. TKIP was designed by the IEEE 802.11i task group and the Wi-Fi Alliance as an interim solution to replace WEP without requiring the replacement of legacy hardware.
Kerberos (/ ˈ k ɜːr b ər ɒ s /) is a computer-network authentication protocol that works on the basis of tickets to allow nodes communicating over a non-secure network to prove their identity to one another in a secure manner.
Systems that use passwords for authentication must have some way to check any password entered to gain access. If the valid passwords are simply stored in a system file or database, an attacker who gains sufficient access to the system will obtain all user passwords, giving the attacker access to all accounts on the attacked system and possibly other systems where users employ the same or ...
