Description

Session tickets are used only to authenticate new connections with servers. Ongoing operations are not interrupted if the session ticket used to authenticate the connection expires during the connection. Satisfies: SRG-OS-000112-GPOS-00057, SRG-OS-000113-GPOS-00058

Check Text (C-205703r1051072_chk)

This applies to domain controllers. It is NA for other systems. Verify the following is configured in the Default Domain Policy: Open "Group Policy Management". Navigate to "Group Policy Objects" in the Domain being reviewed (Forest >> Domains >> Domain). Right-click on the "Default Domain Policy". Select "Edit". Navigate to Computer Configuration >> Policies >> Windows Settings >> Security Settings >> Account Policies >> Kerberos Policy. If the value for "Maximum lifetime for service ticket" is "0" or greater than "600" minutes, this is a finding.

Fix Text (F-5968r355028_fix)

Configure the policy value in the Default Domain Policy for Computer Configuration >> Policies >> Windows Settings >> Security Settings >> Account Policies >> Kerberos Policy >> "Maximum lifetime for service ticket" to a maximum of "600" minutes, but not "0", which equates to "Ticket doesn't expire".
