Hello Steve IMHO, your phrase "For example, the next IIS vulnerability hits. I'd like to have a quick answer to the question, ..." is not compatible with " Periodic - weekly/monthly <--------- me". Perhaps you have to consider Nessus (www.nessus.org) for this task, activating only the needed plugins each time (i.e. new IIS vulnerability -> Windows and Web attack plugins only). Nessus is smart enough to NOT test unusable scripts (i.e. it won't launch a web attack plugin if there's no webserver on the target host). You'll also benefit from excellent reports. Nessus needs a Linux/UNIX box, but you'll need only 1 box for the Nessus server, you can even use a Windows client to use it. It could be that somebody else has a better answer. I'm ready to learn. OTOH, you can consider using some kind of NIDS (for example Snort, from www.snort.org), so new attacks can be detected/stopped by the NIDS, of course you've to worry for having the latest and greatest Snort signatures on place, but then you'll have extra time to do the detailed Nessus scans. Snort is available for Linux/UNIX/Windows. Both tools are free and readily available, and have several updates/week (sometimes).

Here are my definitions: Frequency --------- Continuous - near real-time Periodic - weekly/monthly <--------- me One time - duh Scale ----- Small - a few hosts or maybe a /24 network or two Medium - many networks, up to /16 types <----------- me Large - global Internet or many /8 types Testing Activity ** ------------------- Footprinting Scanning <----------- me Enumeration Penetration ** Taken from Hacking Exposed by the Foundstone guys I have a global network of many /16 through /26 networks. I'd like to develop an inventory of, primarily, machine/OS/Services. I'd prefer to have this relatively up-to-date, but not manually performed. Ultimately, I'd like to have a resource that could help me identify vulnerable devices given the discovery of a new vulnerability rather than having to scan the entire network each time. For example, the next IIS vulnerability hits. I'd like to have a quick answer to the question, "what devices are vulnerable". It doesn't matter if the answer is the result of "list all Windows OS devices with port 80 or 443 open". What are the best practices in this area? I have a cobbled-together solution using nmap that I'm ready to test, but if there is a better low-cost solution I am interested. I've seen ndiff (nmap diff), but I'm not sure that it would be easy to modify that to suit my requirements. How are you dealing with this situation? Thanks!
