Configuration security, in plain language

Notes on the frameworks, attack paths, and real CVEs behind network and system config audits — from the team building ConfGoOne.

Oct 23, 2026·Audit practice

Your scanner report isn't the truth. The configuration is.

Reports from different tools overlap, contradict each other and miss things. Checking every finding against the device's own configuration turns them into one short, defensible list.

The Cisco IOS XE Web UI backdoor: what CVE-2023-20198 actually teaches us

One misconfigured feature, one unauthenticated privilege-escalation bug, and tens of thousands of routers with a planted admin account. Here's what a config audit would have — and wouldn't have — caught.

Why configuration drift is the blind spot in most security audits

A device can pass its audit on Monday and be wide open by Friday, with nobody touching the audit report in between. Point-in-time scans can't see that. Here's what can.

What is attack path analysis (and why a findings list isn't enough)

A list of 40 findings sorted by severity tells you what's wrong. It doesn't tell you which three of them, chained together, get an attacker to domain admin. That's a different question.

CIS Controls vs. NIST 800-53 vs. PCI-DSS: how they actually differ
