### Base/Appliance Settings

Device > Firewall Settings > Administration

For maximum security, it is recommended to make the following changes:

1. Set the firewall name.
2. For PCI/Better Security: Change super user administration account from admin.
3. Set password to force change every 90 days.
4. Bar repeated password changes for 4 changes.
5. Enforce password complexity: Require alphabetic, numeric, and symbolic characters.
6. Apply the above password constraints for all user categories.
7. Enable administrator/user lockout.
8. Failed Login attempts per minute before lockout: 7.
9. Make “Certificate Common Name” the same as the firewall name.
10. Disable “Allow management via HTTP.”
11. Change HTTPS management port from 443 to other (i.e., 9090)
12. Enable “Enhanced Audit Logging”

### Time

Set the following time options:

1. Set time automatically using NTP and set the correct time zone for the location of the firewall.
2. Do not configure additional NTP Servers unless needed for internal synchronization as this will cause a higher load on Core 0.
