Glossary

Framework

A structured collection of tools and conventions for organizing security work.

Vulnerability

A weakness in software, configuration, or process that could be misused.

Risk

The combination of how likely a weakness is to be exploited and its potential impact.

CVE

Common Vulnerabilities and Exposures — a public catalog identifier for a known weakness.

Snapshot

A saved VM state you can restore to undo changes instantly.

Scope

The explicitly authorized set of systems and actions for an assessment.

Knowledge checks

  • I can explain what Metasploit is and why defenders study it.
  • I can describe the four risk levels and what changes between them.
  • I can name the common ports for SSH, DNS, HTTP, and HTTPS.
  • I can set up an isolated virtual lab with a safe training target.
