The problem with relying *only* on automated tools is that you may be
missing some attack vectors that an automated tools may not exploit (such as
the PCI example that Matt brought up). I think the best way to do these
tests is a happy medium of using the automated tools to take care of the
obvious stuff like web server vulnerabilities, combined with manual methods
like manually looking at the responses from the server, and using manual
tools like netcat, etc. The approaches should be complementary, and I can't
think of any reason to only rely on one or the other.

PCI DSS assessment is a very good example for all sorts of applications as all they do is try to enforce good practice.

On a PCI setup we did, we only ran nmap and nessus for the sake of including such tests but everything else was done manually.

Especially when testing a web application, no automated test will know better where there might be an injection possible than you do yourself. Run them, add the results but in the end only thoughrough manual tests will find real vulnerabilities.

Get a third party into it too, if possible. Someone who has no knowledge of the code behind the application but is very imaginative when coming up with attack scenarios.

Dear matt,

Can you give few points as to why we should not automate the assessments or testing? Don't you think the automation helps you in so many ways, one of the best I could think of is "it will be faster compared to manual"??

Regards,
Dharmendra T.

Please, please, please, please, please dont automate this kind of testing and then based upon the results give the customer a pass if nothing found.

I never ever advise automated application assessments to anyone. I personally from the outset at the most automate the spidering of the site and then manually audit it.

Improper session management can really only be assessed manually by looking at the cookie or any session data passed as part of the URL.

There are a number of issues that automated tools will never discover.

Sorry to beat home this fact but at the most automated tools should be run at the end of the test to verify your results.

I know personally of a PCI ASV that i competed against during some work and they used automated scanning, they passed the merchant and i found SQL injection (XP_CMDSHELL level), XSS, CSRF, weak session management, data passed in the clear to name a few.

More than likely this email is going to cause an argument, but please do not automate testing from the outset. Use it to verify your results.

Thanks

Matt.
