🛡️ What is Ethical Hacking?

Ethical hacking, also known as penetration testing or white-hat hacking, involves the authorized practice of bypassing system security to identify potential data breaches and threats in a network. The primary goal is to improve system security by fixing vulnerabilities found during testing.​

🔑 Key Aspects of Ethical Hacking:

• Authorization: Ethical hackers obtain proper approval before conducting any tests.
• Scope Definition: Clearly defining the boundaries of the testing environment.
• Reporting: Documenting findings and providing recommendations.
• Remediation: Assisting in fixing identified vulnerabilities.​Wikipédia, a enciclopédia livreKali LinuxInforma TechTarget
