1.264 RHEL-10-600415

Information

RHEL 10 must automatically lock the root account until the root account is released by an administrator when three unsuccessful login attempts occur during a 15-minute time period.

GROUP ID: V-281195RULE ID: SV-281195r1166537

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