Understanding Ethical Hacking
Ethical hacking (or penetration testing) is the legal practice of bypassing system security to identify vulnerabilities that could be exploited by malicious actors.
Key difference: Ethical hackers have explicit permission to test systems and must report all findings to the organization.
Types of Ethical Hackers
- White Hat: Certified professionals working legally
- Grey Hat: Hack without malicious intent but without authorization
- Black Hat: Malicious hackers (what ethical hackers defend against)
The Ethical Hacking Process
- Reconnaissance: Gathering information about the target
- Scanning: Identifying open ports and services
- Gaining Access: Exploiting vulnerabilities
- Maintaining Access: Testing persistence mechanisms
- Covering Tracks: Removing evidence of testing
- Reporting: Documenting findings for remediation

Legal Considerations
Important Warning
Never attempt to hack systems without explicit written permission. Unauthorized access is illegal under laws like:
- Computer Fraud and Abuse Act (CFAA) – USA
- Computer Misuse Act – UK
- General Data Protection Regulation (GDPR) – EU
Always establish a written testing agreement that defines scope and rules of engagement.
