What exact processes and records are required for vulnerability management in an ISO 27001 audit?

Split the scope in two: infrastructure and codebase. On the infrastructure side, run an open-source vulnerability scanner against your server IP ranges once a month and export the report. On the code side, add a dependency check step into your CI/CD pipeline so builds fail if a known critical vulnerability exists. Those pipeline logs are pure gold to an auditor.

When we prepped for our audit last year, we kept our remediation targets realistic: 7 days for criticals, 30 days for highs, 90 days for mediums. During the initial review, the auditor caught 4 unresolved high-severity vulnerabilities, but seeing signed 'risk acceptance forms' with solid business justifications, they passed us without issuing any non-conformities.

Ensure your audit binder includes these four items: 1) Approved Vulnerability Policy and SLA matrix, 2) Dated scan summary reports covering the last three months, 3) Issue tracker logs demonstrating resolved vulnerabilities, 4) Signed Risk Acceptance Forms for any items left unpatched due to technical or operational constraints.

whatever you do never tell the auditor "we never have vulnerabilities," theyll get suspicious immediately and dig way deeper then like the best approach is always to show a transparent tracker proving that vulnerabilities do pop up, you rank them by severity, and you patch them.

edit: typed from phone, sorry for typos.

do ISO auditors actually accept reports from free open-source scanning tools as official evidence or do they insist on licensed reports from supr expensive enterprise cybersecurity software?

The auditor doesn't care about the tool's brand name, they care about the methodology. Run a scan on all your external IPs with a free tool right away, dump the findings into a spreadsheet assign them to the responsible developers and date-stamp the ones that get resolved. Show a two-month cycle of this and you'll easily pass the audit.

Consultants usually try to intimidate you into buying expensive scanning tools. In reality the standard doesn't demand perfection, it just asks for a defined control mechanism. Even a simple custom automation script and regular ticketing logs will pass the audit as long as they fit into a reasonable framework.

I'll try it.

Let's separate the concepts, they're getting mixed up. If 2FA is on a stolen password alone is useless.

I'm also curious if anyone does it differently.

Correct in theory, but it doesn't work that way in practice. The answer varies greatly by industry; there is no one-size-fits-all rule.

Good luck with that.

it's rare to find an explanation this clear.

I agree, and I'd like to emphasize that. If you get three different answers on a topic, the question was asked wrong.

Good luck with that.

There's a trap here, let me mention it. Start with a small trial; don't commit to everything at once.

I'm also curious if anyone does it differently.

There are three things to check when doing this. Mistakes made on the vulnerability management side are usually reversible but expensive.

Forgotten test environments are more often the entry point than live systems.

I'd say don't rush. People defend habits, not processes. Resistance comes from there.

This is my opinion, I'm not claiming it's absolute truth.

saved.

I was thinking the same thing. When making a decision, first look at what data you have on hand.

Everything goes well for the first three months; problems arise in the fourth. If I were you, I'd go this route.

Noted, thanks.
