CISC-ND-001140 - The Cisco switch must be configured to encrypt SNMP messages using a FIPS 140-2 approved algorithm.

Information

Without the strong encryption that is provided by the SNMP Version 3 User-based Security Model (USM), an unauthorized user can gain access to network management information that can be used to create a network outage.

Solution

Configure the Cisco switch to encrypt SNMP messages using a FIPS 140-2 approved algorithm as shown in the example below:

SW4(config)#snmp-server group V3GROUP v3 priv read V3READ write V3WRITE
SW4(config)#snmp-server user V3USER V3GROUP v3 auth sha xxxxxx priv aes 256 xxxxxx
