		ISAKMP is distinct from key exchange protocols in order to cleanly separate the details of security association management (and key management) from the details of key exchange.
		ISAKMP exchanges provide these assorted networking communities the ability to present peers with the security functionality that the user supports in an authenticated and protected manner for agreement upon a common set of security attributes, i.e.
		ISAKMP requires that the cookie be unique for each SA establishment to help prevent replay attacks, therefore, the date and time MUST be added to the information hashed.

		Standards Track [Page 12] RFC 2408 ISAKMP November 1998 It should be noted that in the exchanges shown in section 4, the anticlogging mechanism should be used in conjuction with a garbage- state collection mechanism; an attacker can still flood a server using packets with bogus IP addresses and cause state to be created.

		IPSEC ISAKMP Transform Identifiers ================================== The IPSEC ISAKMP Transform Identifier is an 8-bit value which identifies a key exchange protocol to be used for the negotiation.
		Requests for assignments of new ISAKMP transform identifiers must be accompanied by an RFC which describes the requested key exchange protocol.
		ISAKMP Domain of Interpretation (DOI) ===================================== The Domain of Interpretation is a 32-bit value which identifies the context in which the Security Association payload is to be evaluated.

	USENIX ;login: - harmful (Site not responding. Last check: 2007-10-25)
		The Internet Security Association and Key Management Protocol (ISAKMP) [RFC-2408] framework was originally developed by the United States National Security Agency (NSA) with an ASN.1 syntax from the initial Fortezza (used in the nefarious Clipper chip).
		ISAKMP replaces the time-variant secret of Photuris with a date and time stamp [RFC-2408, page 20].
		In particular, an adversary can send a large number of ISAKMP proposals, collect the responses in a "cookie jar," then send a large number of key-exchange messages all at once with apparently valid cookie values.

	Setting up a VPN
		ISAKMP manages the exchange of cryptographic keys that you would normally have to manually manage with ipsecadm(8).
		ISAKMP negotiates SAs for IPsec and determines what encryption algorithm to use, how long the keys should be kept and so on.
		This can be modified to let ISAKMP know that only data signed with certain digital certificates, certificates that have been signed by a certain CA, or are using a certain encryption transform are allowed to use IPsec.

	PRESS RELEASE Codenomicon Releases Comprehensive Test Solution for ISAKMP/IKE (Site not responding. Last check: 2007-10-25)
		ISAKMP (Internet Security Association and Key Management Protocol) is a protocol for the exchange of keys and security parameters in electronic communications.
		ISAKMP is designed to provide a framework that is independent of key generation techniques, encryption algorithms and authentication mechanisms.
		IKE (Internet Key Exchange) is an implementation of ISAKMP used for IPSec key management.

		The purpose of this draft is not to replace or enhance the existing authentication mechanisms described in [IKE], but rather to allow them to be extended using legacy authentication mechanisms.
		Readers are advised to be familiar with both [IKE] and [ISAKMP] as well as [IKECFG] since this document is an extension to that document.
		Since XAUTH extends the phase 1 authentication provided by [IKE], it is an important design goal that a legacy user authentication scheme in IPsec be able to use the strengths of current and future authentication and key generation schemes.

	US-CERT Vulnerability Note VU#873334
		ISAKMP (RFC 2408) defines a framework for authentication, key management, and the negotiation of Security Associations (SAs).
		As a result, a specially crafted ISAKMP packet could overflow a static memory buffer, writing arbitrary data on the stack.
		An attacker who is able to send a UDP packet to the ISAKMP service (500/udp) could execute arbitrary code with the privileges of the VPN process, typically root or SYSTEM.

	Step 3: Configuring the ISAKMP Policy
		is 1, IKE provides PFS for the IPSec SA keys and the identities of the ISAKMP negotiating parties (and identities of any parties for which the ISAKAMP parties are acting as proxies).
		When PFS is configured, the IKE daemon creates a new ISAKMP SA for each IPSec SA negotiation and performs a Diffie-Hellman exchange for each IPSec SA negotiation.
		You do not have to go to the ISAKMP policy tab if you have already defined the ISAKMP policy in “Step 3: Configuring the ISAKMP Policy”.

	Setting up a VPN
		ISAKMP (or IKE) is the key exchange mechanism for the VPN.
		In this scenario, the isakmpd.policy file states that anybody who sends data using Encapsulate Security Payload(ESP), and has authenticated with the passphrase mekmitasdigoat (or whatever passphrase you determine), is allowed to use the IPSec stack.
		We can modify this file to let ISAKMP know that we only want to allow data signed with certain digital certificates or using a certain encryption transform.
