Regularly test backups to ensure they can be restored.
8. Use a Password Manager
Password managers generate and securely store strong passwords.
Benefits include:
- Better password security
- Unique credentials for every account
- Easier account management
- Reduced password fatigue
Protect your password manager with a strong master password and MFA.
9. Limit Access to Sensitive Information
Apply the principle of least privilege, meaning users should only have access to the information and systems necessary for their roles.
Organizations should:
- Assign role-based permissions
- Review access regularly
- Remove unused accounts
- Disable access when employees leave
Limiting access reduces the impact of compromised accounts.
10. Secure Mobile Devices
Mobile devices often contain sensitive personal and business information.
Protect them by:
- Using PINs or biometric authentication
- Encrypting storage
- Installing apps only from official stores
- Reviewing app permissions
- Enabling remote locate and wipe features
Keep mobile operating systems and apps updated.
11. Be Careful with Public Wi-Fi
Public Wi-Fi networks can expose users to cyber risks.
When using public Wi-Fi:
- Avoid online banking
