RHEL 10 must automatically lock an account when three unsuccessful login attempts occur during a 15-minute time period.
GROUP ID: V-281196
RULE ID: SV-281196r1166540
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.
