The system enforces confidentiality or integrity policy as a result of a:

  • Client request for confidentiality or integrity
  • QOP policy assigned to the user, IP address, profile, or host group for the session

When only a client request for confidentiality is in effect, the system uses the DEFAULT QOP.

If a session is subject to multiple QOP security policies, the system determines the session security policy and QOP according to the following hierarchy, where the higher number and letter always takes precedence:

  1. No applicable policy
    This is the only policy condition that allows a logon from a pre-14.10 client.
  2. Clear text
    This policy condition occurs only when the has-policy Option applies to a session, but no other client request or policy for confidentiality or integrity applies.
  3. Integrity
    1. Default QOP
    2. Low QOP
    3. Medium QOP
    4. High QOP
  4. Confidentiality
    1. Default QOP
    2. Low QOP
    3. Medium QOP
    4. High QOP
