2. Use Multi-Factor Authentication:
• Require additional verification methods for accessing sensitive data
3. Update and Patch Systems Regularly:
• Install security updates and patches to fix vulnerabilities
4. Implement Firewall and Intrusion Detection Systems:
• Monitor network traffic and block unauthorized access attempts
5. Secure Wireless Networks:
• Use strong encryption protocols like WPA2
• Disable guest networks and change default settings
6. Restrict Access Control:
• Only grant necessary permissions to users based on their roles
• Implement least privilege principle
7. Regularly Backup Data:
• Store backups in secure locations to prevent data loss due to cyber attacks
8. Employee Training and Awareness:
• Educate employees on phishing scams and social engineering tactics
