Extracted from the Wikipedia article Internet Security Association and Key Management Protocol.
Overview
ISAKMP defines the procedures for authenticating a communicating peer, creation and management of Security Associations, key generation techniques and threat mitigation (e.g. denial of service and replay attacks). As a framework, ISAKMP typically utilizes IKE for key exchange, although other methods have been implemented such as Kerberized Internet Negotiation of Keys. A Preliminary SA is formed using this protocol; later a fresh keying is done.
