Central Log Server SRG:
SRG-APP-000345-AU-000400
(in versions v2 r2 through v1 r3)
Title
The Central Log Server must automatically lock the account until the locked account is released by an administrator when three unsuccessful login attempts in 15 minutes are exceeded. (Cat II impact)
Discussion
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.
Check Content
Examine the configuration. Verify that the Central Log Server is configured to lock out the account until released by an administrator when 3 consecutive invalid attempts during a 15 minute period is exceeded. If the Central Log Server is not configured to lock out the account until released by an administrator when 3 consecutive invalid attempts in 15 minutes is exceeded, this is a finding.
Fix Text
Configure the Central Log Server to lock out the account until released by an administrator when 3 consecutive invalid attempts during a 15 minute period is exceeded.
