description: Monitor domains for unusual credential logons. Limit credential overlap across systems to prevent the damage of credential compromise. Ensure that local administrator accounts have complex, unique passwords. Do not allow a user to be a local administrator for multiple systems. Limit domain admin account permissions to domain controllers and limited servers. Delegate other admin functions to separate accounts. (Citation: ADSecurity AD Kerberos Attacks)

For containing the impact of a previously generated golden ticket, reset the built-in KRBTGT account password twice, which will invalidate any existing golden tickets that have been created with the KRBTGT hash and other Kerberos tickets derived from it. (Citation: CERT-EU Golden Ticket Protection)

Attempt to identify and block unknown or malicious software that could be used to obtain Kerberos tickets and use them to authenticate by using whitelisting (Citation: Beechey 2010) tools, like AppLocker, (Citation: Windows Commands JPCERT) (Citation: NSA MS AppLocker) or Software Restriction Policies (Citation: Corio 2008) where appropriate.
