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. SFR ID: FMT_SMF.1(2)b. / IA-7-a Satisfies: SRG-APP-000065

Check Content

To verify the Jamf Pro EMM enforces a limit of three consecutive invalid logon attempts by a user, do the following:

1. Log in to the Jamf Pro EMM console.
2. Open "Settings".
3. Select "Jamf Pro User Accounts & Groups".
4. Select "Password Policy" in the upper right corner.
5. Verify that under "Account Lockout" the number of failed attempts before lockout is set to "3" or less.

If the Jamf Pro EMM does not limit the number of consecutive invalid logon attempts by a user to "3" or less, this is a finding.
