Introduction to Cyber Security — Protect Yourself Online

• What is Cyber Security?
  
  

  

  
  

  Cyber Security is the practice of protecting computers, networks, and data from unauthorized access, attacks, or damage. In today’s world, almost everything is connected to the internet: banking, studying, business, and even social media. This makes security very important because hackers are always looking for weaknesses to exploit.

  Why is Cyber Security Important?

  Many people think cyber attacks happen only to big companies—but that’s not true. Anyone can be a target.
  Hackers can:

  • Steal your Facebook or email account

  • Take your banking information

  • Encrypt your files (Ransomware) and ask for money

  • Spy on your device without you knowing

  So learning how to protect yourself is necessary for everyone.

  Common Cyber Threats

  Here are the most common attacks on the internet:

  Threat Type	Description	Example
  Phishing	Fake messages that trick you into giving personal info	Fake email from “Facebook” asking password
  Malware	Harmful software installed on your device	Apps from unknown websites
  Ransomware	Hacker locks your data and asks for money	"Your files are encrypted, pay to unlock"
  DDoS Attack	Overloading a website to make it stop working	Website becomes slow/unavailable

  How to Protect Yourself

  Follow these basic but powerful steps:

  1. Use Strong and Unique Passwords
     Don’t use: 123456, password, or your birthday. Use long passwords with numbers and symbols.

  2. Enable Two-Factor Authentication (2FA)
     This adds a second layer of security to your accounts (ex: SMS code).

  3. Do Not Download Files from Unknown Sources
     Only install apps from Google Play or official websites.

  4. Keep Your Software Updated
     Updates fix security problems.

  5. Avoid Clicking Unknown Links
     Many hacking attacks start with one click!
