Re: Experience with Qualys Guard (cross posted on web400 as well)

Do you have access to the logs (access.log/php.log/error.log)? That would tell you where the requests are coming from (which can be spoofed) and what they are requesting, then you could use that as backup to ask them why it is doing what it is doing, or it might show you that the requests aren't coming from where you think they are.

Folks:


I got a call yesterday from a customer that is having trouble with a Qualys
Guard scan. Apparently it scans systems for vulnerabilities but when it
comes to a port that has a PHP server on it (in this case Zend Server), it
starts sending over 1000 transactions a second at it, so it becomes a DOS
attack. Qualys firmly denies doing a DOS but I can't understand why the
burst of transactions. Any thoughts?
