I am an IT auditor and I am trying to determine how can I verify the most current security patches for a sample of devices. Here is what the 4 devices have from the "show version" command:
C3750 Boot Loader (C3750-HBOOT-M) Version 12.2(25r)SEC, RELEASE SOFTWARE (fc4)
Cisco IOS Software, CGESM Software (CGESM-LANBASE-M), Version 12.2(25)SED, RELEASE SOFTWARE (fc1)
Cisco IOS Software, C1100 Software (C1100-K9W7-M), Version 12.3(8)JEA, RELEASE
Cisco Internetwork Operating System Software
IOS (tm) C1700 Software (C1710-K9O3SY-M), Version 12.3(2)T, RELEASE SOFTWARE (fc1)
Two of these are routers (the 12.3 versions) and the other are switches (12.2).
How can I tell if these devices have the latest patches applied for those versions? I know 12.4 is available so none of these are current on version, but I need to make sure they have all available security patches.
Any advice would be great for someone who is not a network expert. Thanks.
