  • Example: Subscribe to CERT-In alerts via their official website.

6. Keep Software and Systems Updated

  • Install updates to fix vulnerabilities.
  • Example: Use `sudo apt update && sudo apt upgrade` on Ubuntu.

7. Install Firewalls and Antivirus Software

  • Protect yourself against malware and cyberattacks.
  • Example: Configure `ufw` (Uncomplicated Firewall) on Linux.

8. Use Safer Payment Methods Online

  • Prefer credit cards or trusted platforms.
  • Example: Use `gpg` to encrypt sensitive payment information.

9. Recognize and Avoid Phishing Attempts

  • Verify sender identities before responding.
