1: What is Cybersecurity?
Cybersecurity is the practice of protecting computer systems, networks, software, and data from digital attacks. These attacks can come from hackers who want to:
-
Steal money or sensitive information.
-
Spy on governments or businesses.
-
Cause chaos by shutting down systems.
Cybersecurity includes:
-
Network Security: Protecting networks from unauthorized access.
-
Application Security: Securing apps against bugs and vulnerabilities.
-
Information Security: Keeping sensitive data safe.
-
Cloud Security: Protecting data stored online.
-
Mobile Security: Safeguarding smartphones and portable devices.
Simply put, cybersecurity = digital protection.
2: What is Ethical Hacking?
Ethical hacking is the authorized practice of hacking systems to find weaknesses before criminals do.
-
A hacker breaks into systems illegally.
-
An ethical hacker (also called a white-hat hacker) is hired to test security and protect the system.
For example:
-
A bank may hire an ethical hacker to test if their mobile app can be hacked.
-
A government can hire ethical hackers to strengthen their defense against cyberterrorism.
So, ethical hacking is like a fire drill for cybersecurity — it helps organizations prepare for real threats.
Types of Hackers (White, Black, and Grey Hat)
-
White Hat Hackers: Ethical hackers who protect systems.
-
Black Hat Hackers: Criminal hackers who exploit weaknesses for gain.
-
Grey Hat Hackers: Hackers who break rules but without harmful intent (sometimes they expose flaws without permission).
Ethical hacking focuses only on the white-hat category.
