Penetration Testing (Pen Testing) is a cybersecurity practice where authorized security experts simulate real-world cyberattacks on a system, network, or application to identify vulnerabilities before malicious hackers can exploit them.
In cybersecurity and ethical hacking, penetration testing helps organizations evaluate the strength of their security defenses. It involves scanning, exploiting, and analyzing weaknesses in software, networks, or infrastructure in a controlled and legal environment.
For example:
- A security team tests a banking website to find vulnerabilities in login systems.
- An ethical hacker simulates attacks on a company’s network to check firewall strength.
- A mobile app is tested for data leakage and insecure APIs.
- An organization checks whether employee passwords can be easily compromised.
Common technologies and concepts related to penetration testing include:
- Ethical Hacking
- Vulnerability Assessment
- Network Security
- Exploits & Exploitation
- Security Auditing
- OWASP Top 10
- Kali Linux
- Firewalls
- Encryption & Authentication
