  "account": "Active Directory's Protected Users group enforces strict security measures on its members to defend against credential theft. This group prevents cached credentials, blocks legacy NTLM and Kerberos encryption, and restricts credential delegation. Adding an account to this group is a complex decision, as it impacts both security and compatibility. Administrators cannot work around the limitations once an account is in the group, and services that require NTLM, legacy encryption, or cached credentials may fail.\n\nBefore implementing the group, a pilot should be conducted to identify any dependencies that could cause an outage. The group should be scoped to highly privileged interactive accounts whose credentials would be valuable to an attacker. Domain controller-side restrictions depend on the domain functional level, so the environment must be verified rather than copying policies from other forests.\n\nThe Protected Users group is not a substitute for designing service accounts with specific authentication protocols. If an account requires NTLM or an unsupported encryption type, addressing that dependency is a separate project. The group is not intended to make incompatible applications compatible. Before enforcing the group, audit authentication events to identify potential failures, collect relevant logs, and run a small pilot covering one platform and account type. A successful console logon does not guarantee that service tickets or management tools will work.\n\nIf an account must be removed from the group, a tested break-glass account should be preserved outside routine automation, and its credentials must be protected. The group should be reviewed regularly, and accounts that are no longer privileged or active should be removed. The security value of this group comes from keeping the set small and current. Finally, verify the supported platform boundary, as accounts are protected only where the operating system and domain configuration support the controls.",
