Asociación de seguridad (SA)

Relación establecida entre dos entidades que les permite proteger la información que intercambian.

(en) security association

A relationship established between two or more entities to enable them to protect data they exchange. [CNSSI_4009:2010]

(en) security association

1. (I) A relationship established between two or more entities to enable them to protect data they exchange. (See: association, ISAKMP, SAD. Compare: session.)

2. (I) /IPsec/ A simplex (uni-directional) logical connection created for security purposes and implemented with either AH or ESP (but not both). The security services offered by a security association depend on the protocol (AH or ESP), the IPsec mode (transport or tunnel), the endpoints, and the election of optional services within the protocol. A security association is identified by a triple consisting of (a) a destination IP address, (b) a protocol (AH or ESP) identifier, and (c) a Security Parameter Index.

3. (O) "A set of policy and cryptographic keys that provide security services to network traffic that matches that policy". [R3740] (See: cryptographic association, group security association.)

4. (O) "The totality of communications and security mechanisms and functions (e.g., communications protocols, security protocols, security mechanisms and functions) that securely binds together two security contexts in different end systems or relay systems supporting the same information domain." [DoD6]

[RFC4949:2007]

(en) Security association (SA)

In Internet Protocol Security (IPSec), settings that establish policy and encryption keys used to protect communications between two end points in a Virtual Private Network (VPN). Security associations are negotiated between two computers during the first phase of establishing an Internet Key Exchange (IKE) connection.
