Data center security is the set of policies, precautions and practices adopted at a data center to avoid unauthorized access and manipulation of its resources. [1] The data center houses the enterprise applications and data, hence why providing a proper security system is critical. Denial of service (DoS), theft of confidential information ...
Access-control list. 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] Each entry in a typical ACL specifies a ...
Extensible Authentication Protocol ( EAP) is an authentication framework frequently used in network and internet connections. It is defined in RFC 3748, which made RFC 2284 obsolete, and is updated by RFC 5247 . EAP is an authentication framework for providing the transport and usage of material and parameters generated by EAP methods.
Access control. A sailor checks an identification card (ID) before allowing a vehicle to enter a military installation. In physical security and information security, access control ( AC) is the selective restriction of access to a place or other resource, while access management describes the process. The act of accessing may mean consuming ...
TACACS and XTACACS both allow a remote access server to communicate with an authentication server in order to determine if the user has access to the network. TACACS Plus ( TACACS+ ) is a protocol developed by Cisco and released as an open standard beginning in 1993.
Products in this category are Cisco's range of routers, switches, wireless systems, security systems, WAN acceleration hardware, energy and building management systems and media aware network equipment.

Description. Network access control is a computer networking solution that uses a set of protocols to define and implement a policy that describes how to secure access to network nodes by devices when they initially attempt to access the network. [ 3] NAC might integrate the automatic remediation process (fixing non-compliant nodes before ...
In computer systems security, role-based access control ( RBAC) [ 1][ 2] or role-based security[ 3] is an approach to restricting system access to authorized users, and to implementing mandatory access control (MAC) or discretionary access control (DAC). Role-based access control is a policy-neutral access control mechanism defined around roles ...
