Title

Okta must enforce the limit of three consecutive invalid login attempts by a user during a 15-minute time period. (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. Satisfies: SRG-APP-000065, SRG-APP-000345

Check Content

If Okta Services rely on external directory services for user sourcing, this check is not applicable, and the connected directory services must perform this function. From the Admin Console: 1. Go to Security >> Authenticators. 2. Click the "Actions" button next to "Password" and select "Edit". 3. For each Password Policy, verify the "Lock Out" section has the following values: - "Lock out after 3 unsuccessful attempts" is checked. - The value is set to "3". If Okta Services are not configured to automatically lock user accounts after three consecutive invalid login attempts, this is a finding.
