October is Cybersecurity Awareness Month, a perfect time to focus on protecting your small business from cyber threats. Small businesses are often targeted by cybercriminals because they typically have fewer resources dedicated to cybersecurity. To help you safeguard your business, Middlefield Bank has compiled 10 essential tips to enhance your cybersecurity posture.

1. Educate Your Employees

Your employees are your first line of defense. Conduct regular training sessions to help them recognize phishing attempts, understand the importance of strong passwords, and follow best practices for data security.

• TIP: Schedule quarterly cybersecurity workshops and use real-life phishing examples to train employees on identifying suspicious emails.

2. Use Strong Passwords and a Password Manager

Encourage the use of complex passwords that combine letters, numbers, and symbols. A password manager can help employees generate and store unique passwords securely.

• TIP: Implement a policy requiring passwords to be at least 12 characters long and change them every 90 days.

3. Enable Multi-Factor Authentication (MFA)

MFA adds an extra layer of security by requiring a second form of verification, such as a text message or authentication app, in addition to a password.

• TIP: Use MFA for all critical systems, including email, financial accounts, and any platform that stores sensitive customer data.

4. Keep Software Updated

Regularly update all software, including operating systems, antivirus programs, and applications. Updates often include patches for security vulnerabilities.

• TIP: Set up automatic updates for all software and schedule regular checks to ensure all systems are up to date.

5. Backup Your Data

Regularly back up your data to an offsite location or cloud service. This ensures you can recover your information in case of a ransomware attack or other data loss incidents.

• TIP: Use a 3-2-1 backup strategy: three copies of your data, on two different media, with one copy offsite.

6. Secure Your Wi-Fi Networks 

Ensure your business Wi-Fi networks are encrypted and hidden. Use strong passwords and consider setting up a separate network for guests.

• TIP: Change your Wi-Fi passwords regularly and use WPA3 encryption for the highest level of security.

7. Implement Firewalls and Antivirus Software 

Firewalls and antivirus software provide essential protection against malware and other cyber threats. Ensure these tools are installed and regularly updated.

• TIP: Conduct monthly scans and reviews of firewall and antivirus logs to detect any unusual activity.

8. Limit Access to Sensitive Information 

Only grant access to sensitive data to employees who need it for their job. Implement role-based access controls and regularly review permissions.

• TIP: Use the principle of least privilege (PoLP) to ensure employees only have access to the information necessary for their roles.

9. Develop a Cybersecurity Policy 

Create a comprehensive cybersecurity policy that outlines your security protocols and procedures. Ensure all employees are familiar with the policy and understand their responsibilities.

• TIP: Review and update your cybersecurity policy annually and after any significant changes to your IT infrastructure.

10. Monitor and Respond to Threats 

Regularly monitor your systems for unusual activity and have a response plan in place for potential security incidents. Quick detection and response can minimize the impact of a cyber attack.

• TIP: Use a Security Information and Event Management (SIEM) system to centralize and analyze security alerts from across your network.
