Description
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.

ℹ️ Check
Review Sentry configuration to verify that it enforces the limit of three consecutive invalid logon attempts. 1. Log in to Sentry System Manager portal. 2. Go to the "Security" tab. 3. Go to "Password Policy". 4. Look for "Number of Failed Attempts" and determine if the value is set to 3. If it is not, this is a finding. 5. Verify the Auto-Lock Time value is set to 900 seconds or more. If the Auto-Lock Time is not set to 900 seconds or more, this is a finding.
