Security Management
Cisco MGM security uses the mechanisms of Cisco EMF, which authenticates users based on names and
passwords. When using the Cisco WebViewer or CLI management interfaces, the Cisco MGX 8260
Media Gateway also authenticates users based on Cisco MGX 8260 user accounts. Both systems support
security profiles that define access rights for typical users, from administrators to guests.
Messages between Cisco MGM and network elements is secured using SNMP community strings. You
configure unique community strings known by all network elements to limit and control access.
Cisco MGM Architecture
Cisco MGM extends the functionality of Cisco EMF to include management of Cisco MGX 8260 Media
Gateways (see Figure 1-1).
