AMLS-NM-000120 - The Arista Multilayer Switch must automatically audit account creation.

Information

Upon gaining access to a network device, an attacker will often first attempt to create a persistent method of reestablishing access. One way to accomplish this is to create a new account. Notification of account creation helps to mitigate this risk. Auditing account creation provides the necessary reconciliation that account management procedures are being followed. Without this audit trail, personnel without the proper authorization may gain access to critical network nodes.

Solution

Enable logging on the switch with sufficient detail to fulfill the specifications set forth in the VulDiscussion.

To configure logging to a remote syslog server at the informational level, enter:

switch#config
switch(config)#logging host [ip address]
switch(config)#logging trap informational

Then configure the following AAA:

aaa accounting commands all default start-stop logging [group radius]
