The following security controls should be applied to the application (check the NIST Security Controls Database for details, description and guidance for each control:

• AC-7 - UNSUCCESSFUL LOGON ATTEMPTS
• AC-8 - SYSTEM USE NOTIFICATION
• AU-3 - CONTENT OF AUDIT RECORDS
• AU-8 - TIME STAMPS
• IA-2(1) IDENTIFICATION AND AUTHENTICATION (ORGANIZATIONAL USERS) | NETWORK ACCESS TO PRIVILEGED ACCOUNTS (Note this is an enhancement of an existing low-impact security control)
• Select one additional low-impact security control and implement it. This can be an enhancement or a required low-impact security control. Selecting a control that provides documentation as opposed to code changes is also acceptable and encouraged.
