01Introduction
Attackers rarely start with an exploit. They start with information: an org chart on a social network, a stack trace in an error page, an internal hostname in a public repository. Operational security is about not handing that over.
02What is OPSEC?
Operational security (OPSEC) is a risk management process, originally military, for identifying critical information, analyzing how adversaries could collect it, and applying measures to deny them that information.
In a company it covers what employees share, what systems reveal about themselves (verbose errors, exposed metadata, leaked secrets) and how operational processes such as access management and change control are run. It is distinct from SecOps, which is the team function.
03How OPSEC works
OPSEC is traditionally a five-step cycle.
- 1.
Identify critical information
Customer data, credentials, architecture details, roadmap.
- 2.
Analyze threats
Who wants it and what they are capable of. See threat intelligence.
- 3.
Analyze vulnerabilities
How that information could leak through people, processes or systems.
- 4.
Assess risk and apply countermeasures
Prioritize and fix, for example by removing verbose errors, rotating secrets and training staff.
04Threats and risks
Most leaks are unintentional.
Information disclosure
Stack traces, debug endpoints and version banners that map your stack for an attacker.
Credential exposure
Secrets in code, logs and tickets.
Social engineering
Public information used to craft convincing phishing.
Exposed infrastructure
Internal services reachable from the internet. See attack surface management.
05How Parameter helps
Parameter finds what your systems give away.
Information leaks in the app
The pentesting agents flag verbose errors, exposed debug routes and metadata leaks.
Secrets in history
Secrets detection scans every commit and branch.
Exposed assets
External attack surface management maps what's reachable from outside.
