Simple Network Management Protocol
Cisco Security Appliances allow limited Simple Network Management Protocol (SNMP)
support. Because SNMP was designed as a network management protocol and not a security
protocol, it can be used to exploit a device. For this reason, Cisco Security Appliances allow
only read-only access to remote connections. This enables the manager to remotely connect
to the device and monitor SNMP traps but does not allow the manager to change any SNMP
settings.
