1.266 RHEL-10-600425

Information

RHEL 10 must maintain an account lock until the locked account is released by an administrator.

GROUP ID: V-281197RULE ID: SV-281197r1166543

By limiting the number of failed login attempts, the risk of unauthorized system access via user password guessing, otherwise known as brute-forcing, is reduced. Limits are imposed by locking the account.
