Sealed with an XSS: Popular vulnerabilities probed

You don't have to be an infosec genius to protect yourself

If we have internet-facing web servers (and other types of server, for that matter) we care about how vulnerable they are to attack. There are loads of services out there that you can use to probe your public-facing systems, and they'll tell you loads of useful stuff about why they might be vulnerable. But of course they're only useful if you understand what on Earth the probe service is telling you."
