Definition:
Hacking is the act of unauthorized access to or control over a computer system, network, or digital data, usually with the intent to steal, alter, or destroy information, disrupt services, or gain illegal advantage.
Hacking can be done by individuals (hackers), groups, or even state-sponsored entities. While some hacking is ethical and legal (e.g., cybersecurity testing), most forms of hacking are illegal and punishable by law.

|---|---|
| Black Hat Hackers | Malicious hackers who break into systems to steal data, harm networks, or cause disruption. |
| White Hat Hackers | Ethical hackers who use their skills to find and fix vulnerabilities with permission. |
| Grey Hat Hackers | Hackers who may violate laws or ethical standards, but without malicious intent. |
| Script Kiddies | Inexperienced hackers who use pre-written code to launch attacks without deep knowledge. |

Preventive Measures Against Hacking:
- Strong Passwords and 2FA (Two-Factor Authentication)
- Updated Antivirus and Firewalls
- Regular Software Updates and Patches
- Avoid Clicking on Suspicious Links or Attachments
- Cybersecurity Awareness and Training
- Network Monitoring and Encryption
- Ethical Hacking & Penetration Testing
Ethical Hacking:
Also called penetration testing, it involves testing a system’s security with permission to:
- Identify vulnerabilities
- Improve cyber defense
- Prevent real hacking attempts
Ethical hackers are often certified (e.g., CEH – Certified Ethical Hacker).
