A Pen Tester (Penetration Tester) is a cybersecurity professional who simulates attacks on systems to identify security vulnerabilities.
Key Features:
- Simulated Attacks: Performs controlled hacking attempts on applications, networks, or systems.
- Tool Utilisation: Uses tools like Metasploit, Nmap and Burp Suite for vulnerability assessment.
- Detailed Reporting: Analyses findings and provides recommendations to improve security defences.
Benefits:
- Identifies weaknesses before real attackers exploit them.
- Improves an organisation’s overall security posture.
- Validates the effectiveness of existing security controls.
Challenges:
- Keeping up with evolving hacking techniques and tools.
- Balancing realistic attack simulation with avoiding system disruption.
Example:
A pen tester may exploit misconfigured firewalls or weak passwords to demonstrate potential access points for attackers.
