01Introduction
Attackers don't think in CVE lists. They chain a public bucket to an over-permissive role to a database. Exposure management is the shift from counting individual flaws to understanding the paths they form.
02What is Exposure management?
Exposure management is the practice of continuously identifying, evaluating and reducing every way an attacker could reach valuable assets. That includes software vulnerabilities, cloud misconfigurations, excessive identity permissions, leaked credentials and exposed services, viewed together through attack path analysis.
Vulnerability management asks 'what is broken?'. Exposure management asks 'what can an attacker do with what is broken?'. CTEM is the most common framework for running it.
03How Exposure management works
Exposure management builds a model of how an attacker would move.
- 1.
Map the surface
Combine external assets, cloud resources, identities, code and dependencies into one inventory.
- 2.
Model paths
Connect weaknesses that can be chained: an entry point, a pivot, a privilege gain, a target.
- 3.
Find choke points
Identify the few fixes that break the most paths to critical data.
- 4.
Validate and fix
Confirm the paths are real and close them at the choke point.
04Threats and risks
The exposures that hurt are usually combinations.
Toxic combinations
Individually medium findings that combine into a critical path.
Identity sprawl
Unused roles, long-lived keys and wildcard permissions widen every path. See zero trust.
Leaked secrets
A credential in git history can skip every other control. See secrets detection.
Unknown assets
Forgotten subdomains and test environments are entry points no one monitors.
05How Parameter helps
Parameter maps and proves attack paths across your application, cloud and code.
Cloud attack paths
Cloud Security reasons about how IAM, network and data settings chain together, and ranks by attacker reach.
Application paths
The pentesting agents chain auth, authorization and logic flaws the way an attacker would.
Supply chain and secrets
Supply Chain and secrets detection close the entry points that bypass the perimeter.
