  • Verification Points
  • 	If the ISAKMP message length and the value in
    	the Payload Length field of the ISAKMP Header are not the same, then
    	the ISAKMP message MUST be rejected.  The receiving entity (initiator
    	or responder) MUST do the following:
    1. The event, UNEQUAL PAYLOAD LENGTHS, MAY be logged in the appropriate system audit file.
    2. An Informational Exchange with a Notification payload containing the UNEQUAL-PAYLOAD-LENGTHS message type MAY be sent to the transmitting entity. This action is dictated by a system security policy.

  • Configuration
    •        
    • ISAKMP Header Format(HOST-2:Initiator)
    • Length field = 0 (invalid value)
    • Initiator and Responder IKE parameter
    • At least, following parameter must be included in proposal.

=end html =head1 TEST PROCEDURE =begin html
  This test check is following.

IDENTITY PROTECTION EXCHANGE
# Initiator(TN) Direction Responder(NUT) (1) HDR; SA ========> <-----Length field(ISAKMP header) : 0(invalid)
(2-A) X <======== HDR; KE; NONCE <-----Must not transmit or (2-B) <======== HDR; N/D Judgement (Check *1)
1. Send the first message from TN In the first message (1), the initiator generates a proposal it considers adequate to protect traffic for the given situation. The Security Association, Proposal, and Transform payloads are included in the Security Association payload (for notation purposes).
2. Receive the second message from NUT In the second message (2-B), the responder indicates either an ISAKMP Notify Payload or an ISAKMP delete Payload.
=end html =head1 JUDGEMENT The first message must not be accepted. And the second message must not be returned (* or UNEQUAL-PAYLOAD-LENGTHS message is returned). *option : if you want to check the retruned Notify message. =head1 TERMINATION Clean up SAD and SPD =head1 REFERENCE =begin html
  RFC2408
  5.1 General Message Processing

Every ISAKMP message has basic processing applied to insure protocol reliability, and to minimize threats, such as denial of service and replay attacks. All processing SHOULD include packet length checks to insure the packet received is at least as long as the length given in the ISAKMP Header. If the ISAKMP message length and the value in the Payload Length field of the ISAKMP Header are not the same, then the ISAKMP message MUST be rejected. The receiving entity (initiator or responder) MUST do the following:
1. The event, UNEQUAL PAYLOAD LENGTHS, MAY be logged in the appropriate system audit file.
2. An Informational Exchange with a Notification payload containing the UNEQUAL-PAYLOAD-LENGTHS message type MAY be sent to the transmitting entity. This action is dictated by a system security policy.
