About this interactive
The Vulnerability Management lesson runs identify, analyze, report, remediate and verify. This activity practises the first step: where vulnerabilities come from. The lesson names five sources.
The vendor reports it. Software makers find flaws in their own products and announce them, usually with a patch: an advisory, a security notice, an update banner.
A vulnerability scan finds it. Scanning software checks your systems against known weaknesses and reports what it found, often with a risk level.
A feed or forum publishes it. Third parties track vulnerabilities: the CVE list of common vulnerabilities and exposures, threat intelligence feeds, mailing lists and admin forums. The difference from the first source is who is speaking: a feed is someone other than the maker.
A penetration test proves it. Testers you hire, or an internal team, actively try to break in and report what worked.
A disclosure program brings it in. You invite outsiders to look for flaws and report them, often for a reward such as a gift card or a bug bounty. The difference from a penetration test is that nobody was hired: the researcher found it on their own and reported it through your program.
However a vulnerability was found, the lesson ends the process by checking the fix the same way.
