Firewalls are like the security guards of a network—they monitor and control incoming and outgoing traffic based on predefined security rules. Their main job is to protect your network from unauthorized access, cyberattacks, and data breaches. 

Ransomware is a type of malicious software that locks or encrypts your files, making them inaccessible, and then demands payment (a ransom) to unlock them.
It’s like a digital kidnapper holding your data hostage.

How it works:

  1. You unknowingly download or trigger the ransomware (often via phishing emails, infected websites, or malicious downloads).

  2. It quickly encrypts your files or locks your device.

  3. A ransom note appears, demanding payment — often in cryptocurrency — with threats of permanent data loss.

Prevention Tips

  1. Regular Backups – Keep copies of your important files on an offline or cloud backup.

  2. Be Cautious with Emails – Don’t click suspicious links or open unexpected attachments.

  3. Use Strong Security Software – Keep antivirus, anti-malware, and firewalls active and updated.

  4. Update Your System – Install software and OS updates to patch known vulnerabilities.

  5. Enable Multi-Factor Authentication – Prevent attackers from gaining account access even if they steal your credentials.

  6. Limit User Privileges – Avoid using accounts with admin rights for everyday work.

  7. Educate Yourself & Your Team – Awareness is one of the strongest defenses.
