Kerberos tickets have a limited lifetime so the time an attacker has to implement an attack is limited. This policy controls how long TGTs can be renewed. With Kerberos, the user's initial authentication to the domain controller results in a TGT which is then used to request Service Tickets to resources. Upon startup, each computer gets a TGT before requesting a service ticket to the domain controller and any other computers it needs to access.

The account and password are created when a domain is created and the password is typically not changed. If the krbtgt account is compromised, attackers can create valid Kerberos Ticket Granting Tickets (TGT). The password must be changed twice to effectively remove the password history.Changing once, waiting for replication to complete and the amount of time equal to or greater than the maximum Kerberos ticket lifetime, and changing again reduces the risk of issues. </VulnDiscussion><FalsePositives></FalsePositives><FalseNegatives></FalseNegatives><Documentable>false</Documentable><Mitigations></Mitigations><SeverityOverrideGuidance></SeverityOverrideGuidance><PotentialImpacts></PotentialImpacts><ThirdPartyTools></ThirdPartyTools><MitigationControl></MitigationControl><Responsibility></Responsibility><IAControls></IAControls></description><reference><dc:title>DPMS Target Windows Server 2012-2012 R2 Domain Controller</dc:title><dc:publisher>DISA</dc:publisher><dc:type>DPMS Target</dc:type><dc:subject>Windows Server 2012-2012 R2 Domain Controller</dc:subject><dc:identifier>4217</dc:identifier></reference><ident system="http://cyber.mil/legacy">SV-101879</ident><ident system="http://cyber.mil/legacy">V-91777</ident><ident system="http://cyber.mil/cci">CCI-000366</ident><fixtext fixref="F-27774r794808_fix">Reset the password for the krbtgt account a least every 180 days. The password must be changed twice to effectively remove the password history. Changing once, waiting for replication to complete and changing again reduces the risk of issues. Changing twice in rapid succession forces clients to re-authenticate (including application services) but is desired if a compromise is suspected. PowerShell scripts are available to accomplish this such as at the following link: https://gallery.technet.microsoft.com/Reset-the-krbtgt-account-581a9e51 Open "Active Directory Users and Computers" (available from various menus or run "dsa.msc"). Select "Advanced Features" in the "View" menu if not previously selected. Select the "Users" node. Right click on the krbtgt account and select "Reset password". Enter a password that meets password complexity requirements. Clear the "User must change password at next logon" check box.

That is, if a user starts a process and then logs out, there is a potential that the next user who logs in to the system could access the previous users process.
