1. Keep software up to date: Keeping all the software on your devices up to date is paramount to avoiding a cyber security breach. 

2. Use secure passwords: Secure passwords are essential for preventing unauthorized access to your network. Ensure that your passwords are strong, do not use the same password for more than one account, and change them regularly.

3. Implement two-factor authentication: Two-factor authentication requires two pieces of evidence to access a system, such as one in the form of something a user knows, such as a password, and one in the form of something a user has, such as a smartphone.

4. Protect mobile devices: Many cyber security breaches originate from unauthorized access to mobile devices. Make sure to use a secure lock screen, enable remote wipe, and use caution when accessing public Wi-Fi networks.

5. Use a firewall: A firewall can help protect your network by monitoring incoming and outgoing traffic and blocking malicious activity.

6. Use encryption: Encryption is the process of transforming plain text into a code that cannot be accessed without the right key. This is especially important for protecting sensitive data.

7. Educate your employees: Employees should be regularly educated on the latest cyber security threats and best practices. Make sure they know the risks of opening malicious emails and links, and the importance of strong passwords.
