Description
The IPsec security association (SA) and its corresponding key will expire either after the number of seconds or amount of traffic volume has exceeded the configured limit. A new SA is negotiated before the lifetime threshold of the existing SA is reached to ensure that a new SA is ready for use when the old one expires. The longer the lifetime of the IPsec SA, the longer the lifetime of the session key used to protect IP traffic. The SA is less secure with a longer lifetime because an attacker has a greater opportunity to collect traffic encrypted by the same key and subject it to cryptanalysis. However, a shorter lifetime causes IPsec peers to renegotiate Phase 2, more often resulting in the expenditure of additional resources. Specify the lifetime (in seconds) of an Internet Key Exchange (IKE) SA. When the SA expires, it is replaced by a new SA, the Security Parameter Index (SPI), or terminated if the peer cannot be contacted for renegotiation.

Who does this work

13 NICE work roles and 9 EC-Council certifications.

This is an inference across published mappings, not a single claim by anyone. This check maps to a control, which maps to a Cybersecurity Framework outcome, which NIST assigns to the work roles below. EC-Council separately maps its certifications to those same roles.

A certification prepares someone for a role. It is not evidence that a holder is qualified, and neither NIST nor EC-Council has stated that any certification here addresses this check.

Work-role assignments published by NIST (NICE Framework Components 2.2.0 and the CSF 2.0 OLIR crosswalk). Certification mappings published by EC-Council.

Check Text (C-239963r1015263_chk)

Verify the VPN gateway renegotiates the security association after eight hours or less as shown in the example below. crypto map IPSEC_MAP 10 match address SITE1_SITE2 crypto map IPSEC_MAP 10 set peer x.x.x.x … … … crypto map IPSEC_MAP 10 set security-association lifetime seconds 3600 If the VPN Gateway does not renegotiate the security association after eight hours or less, this is a finding.

Fix Text (F-43155r666294_fix)

Configure the VPN gateway to renegotiate the security association after eight hours or less as shown in the example below. ASA1(config)# crypto map IPSEC_MAP 10 set security-association lifetime seconds 28800 ASA1(config)# end
