What Exactly is Ethical Hacking?

Ethical hacking, often referred to as penetration testing or white-hat hacking, is the authorized practice of bypassing system security to identify potential data breaches and threats in a network or system. The organization that owns the system allows the hacker to attempt to exploit vulnerabilities. The hacker then provides a detailed report on their findings and suggests ways to fix the security issues. Think of it as a simulated cyberattack designed to identify exploitable weaknesses before malicious actors can. This isn't about brute-forcing your way into systems without permission. It's a disciplined approach that requires a deep understanding of network protocols, operating systems, programming languages, and various exploitation techniques. An ethical hacker operates within a strict legal and ethical framework, ensuring that their actions are always sanctioned and that the knowledge gained is used for remediation and strengthening defenses.
