T1087 Account Discovery Discovery
Adversaries may attempt to get a listing of valid accounts, usernames, or email addresses on a system or within a compromised environment.

Why these techniques?

Information disclosure of user login timestamps directly enables account discovery (T1087) via unauthorized enumeration of account activity metadata.

Mitigating Controls (NIST 800-53 r5) AI

AC-3 Access Enforcement good match
prevent

Enforces access control policies so that login timestamps cannot be retrieved or sorted by unauthorized actors via explore/users.

AC-4 Information Flow Enforcement good match
prevent

Controls information flows to block exposure of sensitive user activity data (lastlogintime) through application features.

AC-6 Least Privilege partial match
prevent

Restricts privileges so that only users with an explicit need can obtain or query other users' login timestamps.

PR.AA-05 mostly match
prevents

Enforcing least-privilege access permissions directly prevents unauthorized actors from reaching sensitive system information.

PR.IR-01 mostly match
prevents

Protecting environments from unauthorized logical access stops exposure of internal system details to outsiders.

PR.PS-06 partial match
prevents

Secure-development practices reduce the chance of code paths that leak sensitive system information.
