DING DING DING!
Whom will prevail! Two of my favorite tools at hand, one is for offence and one is for defence however we can argue that both are for defence if you analyse it from another point of vue.
With what looks like one of the coolest logos:
The ZAP Attack Proxy is a free tool from OWASP that can act as a proxy intercepting traffic for analysis and also performs scans. Not to mention it can integrate with a large number of other tools.
From their site:
The OWASP Zed Attack Proxy (ZAP) is one of the world’s most popular free security tools and is actively maintained by hundreds of international volunteers*. It can help you automatically find security vulnerabilities in your web applications while you are developing and testing your applications. Its also a great tool for experienced pentesters to use for manual security testing.
Let’s get into the action. I have two sites on IIS , one is being secured by ModSecurity and the other isn’t. Let’s see the variances.
Port 80 is secured and 2016 has just seen a run.
When firing the execution on hte port 80 rendition we get a 403 which is what we want. Not long ago a consultant came in and advised us to use this tool , which I also advise! However I said what do you do if we have an IDS that knows this signature and stops the traffic instantly? She had not seen such a thing before usually seeing the tooling continue on with the scan. Now using this tool as aproxy to intercept is a different ball game.
Take away, how many different scanners have you tested against your site? Do you stop them instantly? Do you have forensics telling you someone at x IP address is constantly scanning?
Food for thought!
