SNMP cisco Community String (deprecated)
High Nessus Network Monitor Plugin ID 1405
SynopsisThe remote host is configured with default or easily-guessed credentials.
DescriptionThe remote host is running an SNMPv2 server that uses a well-known community string - cisco
SolutionThis signature was obtained through direct sniffing of the network, so if possible, migrating systems to SNMP v3 would be more secure. For non-local attacks though, your community string is easily guessed and should be changed to something more random.
