- Guide pen testing – Subject material consultants could manually carry out sure assaults in opposition to identified applied sciences and methods.
- The exploitation of vulnerabilities – If a vulnerability is discovered, the scope of the vulnerability might be assessed. How far-reaching is the vulnerability? What’s criticality?
- Evaluation and report – Pen testers will normally ship an evaluation of the pen check outcomes, rating the criticality of any vulnerabilities discovered. As soon as these are analyzed, a report is normally part of the deliverables from the pen check.
