CISC-ND-000940 - The Cisco switch must be configured to audit the execution of privileged functions.

Information

Misuse of privileged functions, either intentionally or unintentionally by authorized users, or by unauthorized external entities that have compromised information system accounts, is a serious and ongoing concern and can have significant adverse impacts on organizations. Auditing the use of privileged functions is one way to detect such misuse and identify the risk from insider threats and the advanced persistent threat.

Solution

Configure the Cisco switch to log all configuration changes as shown in the following example:

Step 1: Configure the AAA servers as shown in the example below:

SW1(config)# radius-server host 10.1.48.10
SW1(config)# radius-server host 10.1.48.12

Step 2: Configure an AAA server group as shown in the example below:

SW1(config)# aaa group server radius RADIUS_SERVERS
SW1(config-radius)# server 10.1.48.10
SW1(config-radius)# server 10.1.48.12
SW1(config-radius)# exit

Step 3: Enable AAA accounting as shown in the example below:

SW1(config)# aaa accounting default group RADIUS_SERVERS
SW1(config)# end
