Re: AppScan and IDS evasion

You could slow down the testing. Don't launch a full bore scan, pick one or two tests at a time. If you're looking for XSS or SQL injection, only use those tests. AppScan and any other web scanner is REALLY noisy.

If you can grab another IP from your provider I'd attack it that way.

Cheers!

Hello,

I've launched AppScan against a web application and I'm being
blocked/banned (since I have a dynamic IP I can reboot my router and
get another IP, which is shortly banned again, as long as the attack
persists). Since AppScan doesn't have any kind of IDS evasion (AFAIK),
what could I do?

Of course, I can perform a manual audit (which I was going to do
anyway, automatic scanners are only the first phase) but do you have
other ideas to bypass the locking mechanism? Perhaps I could put in
place some kind of proxy applying IDS-evasion techniques, so I could
configure AppScan to use that proxy, and this last one would be in
charge of manipulate/rewrite the requests to bypass IDS. Does such a
proxy exist?

It would be nice if you could point to some good and practical
anti-IDS paper, doc and tools.

Thank you.

PS: I don't know which kind of IDS is in use (perhaps it's not a
full-IDS but some anomaly detection as the one included in Checkpoint
FW-1 but I don't have that information).

Cheers,
