Cisco Newbie - know nothing
One of our subsidiary companies has a Cisco 2821 connected to both data and voice providers links. This device is uspported by a thrid party. Recently the device was compromised and a large phone bill was run up with the calls being made from the Cisco 2821. The local maintainer made changes to the 2821 as a result of the compromise (I have details of the cisco config logs before and after the change). My question is - is there ahjyway to interrogate the cisco config to ascertain what secuirty fixes have been applied and when ?
Many thanks for any help you can offer ?
