A packet layer security standard consisting of Authentication Header (AH) and Encapsulating Security Payload (ESP) elements, defined in RFC 2402 and RFC 2406 respectively. Useful for Virtual Private Networks.
(a) the IETF working society which is specifying a security architecture (RFC 2401) and protocols in order to provide services of security for Internet Protocol traffic. (b) a collective name for that architecture and set of protocols, specifying security protocols (AH and ESP, the Authentication Header and Encapsulating Security Payload), Security associations, PKI key management, and Algorithms for authentication and encryption. Besides SSL encryption and also 128-bit encryption and SSL digital certificates or 128-bit certificates, the set of security services include access control service, connectionless data integrity, data origin authentication for secure authentication or secure SSL authentication, protection against replays, data confidentiality service and limited traffic flow confidentiality.
A collection of Internet standards for protecting IP packets with encryption and authentication.
A set of industry-standard, cryptography-based protection services and protocols. IPSec protects all protocols in the TCP/IP protocol suite and Internet communications using L2TP. See also Layer Two Tunneling Protocol (L2TP).
Providing security for transmission of sensitive information over unprotected networks
A set of standards to deal with general attributes and policy regarding computer network security, encryption, authentication, keys and key exchange.
IPsec (Internet Protocol Security) is a set of protocols developed by the Internet Engineering Task Force IETF) to support secure exchange of packets at the IPv6 layer.
A protocol that authenticates data entering and encrypts data leaving an IPsec enabled computer and is transparent to the user who does not have to purposely invoke cryptographic protections. It consists of two related parts—one which manages authentication and key exchange, the other which handles the bulk encryption process—and is custom built for each operating system.
Internet Protocol Security (IPSec) refers to a series of Internet Engineering Task Force (IETF) guidelines developed for the protection of Internet Protocol (IP) communications.
