Use Interface Management Profiles to Restrict Access
An Interface Management profile protects the firewall from unauthorized access by defining the protocols, services, and IP addresses that a firewall interface permits for management traffic. For example, you might want to prevent users from accessing the firewall web interface over the ethernet1/1 interface but allow that interface to receive SNMP queries from your network monitoring system. In this case, you would enable SNMP and disable HTTP/HTTPS in an Interface Management profile and assign the profile to ethernet1/1.
You can assign an Interface Management profile to Layer 3 Ethernet interfaces (including subinterfaces) and to logical interfaces (aggregate group, VLAN, loopback, and tunnel interfaces). If you do not assign an Interface Management profile to an interface, it denies access for all IP addresses, protocols, and services by default.
The management (MGT) interface does not require an Interface Management profile. You restrict protocols, services, and IP addresses for the MGT interface when you Perform Initial Configuration of the firewall. In case the MGT interface goes down, allowing management access over another interface enables you to continue managing the firewall.
When enabling access to a firewall interface using an Interface Management profile, do not enable management access (HTTP, HTTPS, SSH, or Telnet) from the internet or from other untrusted zones inside your enterprise security boundary, and never enable HTTP or Telnet access because those protocols transmit in cleartext. Follow the Best Practices for Securing Administrative Access to ensure that you are properly securing management access to your firewall.
