15 Best Practices for Small Business Cybersecurity

Are you concerned about the rising threat of cyberattacks on your small business? Cybersecurity has become a critical focus for businesses of all sizes, but small businesses often face unique challenges in protecting their systems and data.

Small businesses are frequent targets for cybercriminals due to often having fewer resources dedicated to cybersecurity. A single breach can lead to financial losses, operational disruptions, and a loss of trust from your customers.

In this blog, we will explore 15 best practices for small business cybersecurity and share actionable steps to improve your business’s digital security.

What Are the 15 Best Practices for Small Business Cybersecurity?

Securing your small business from cyber threats requires a proactive approach. By implementing these 15 best practices, you can protect your sensitive data, maintain customer trust, and ensure smooth operations even in the face of potential attacks.

Here we explore the 15 best practices for small business cybersecurity:

1. Train Your Employees

Your employees are your first line of defence. Educate them about recognising phishing attempts, creating secure passwords, and the importance of handling sensitive information carefully. Regular training sessions can significantly reduce human error, a leading cause of cyber breaches.
Encourage employees to report suspicious activity immediately to prevent potential attacks. Use fake phishing exercises to test their awareness regularly. Also, ensure they understand the importance of not clicking on unknown links or attachments in emails.

2. Carry Out Risk Assessment

Identify vulnerabilities in your systems by performing regular risk assessments. This allows you to address weak spots and prioritise security measures to reduce potential threats effectively.
Map out your business's digital and physical assets to understand where risks lie. Conduct penetration testing to copy attacks and assess your defences. Document the findings and create a plan to address the identified vulnerabilities promptly.

3. Install Antivirus Software

Install reputable antivirus software to detect and reduce malware before it can harm your systems. Ensure it is configured to update and run scans automatically for optimal protection.
Choose antivirus software with additional features like anti-phishing and ransomware protection. Educate your team on recognising when antivirus alerts require immediate action. Periodically review the software's performance to ensure it meets your business needs.

4. Keep Software Updated

Outdated software is an easy target for hackers. Regularly update your operating systems, applications, and plugins to patch vulnerabilities and protect against the latest threats.

Enable automatic updates wherever possible to ensure critical patches are applied. Monitor third-party applications connected to your systems for update notifications. Keep a record of updates to ensure all devices are running the latest versions.

5. Back Up Your Files Regularly

Data loss can be harmful for small businesses. Schedule automatic backups to secure locations such as the cloud or external hard drives to ensure critical files are never lost.

Perform routine checks to verify that backups are complete and accessible. Use encryption to secure backup files from unauthorised access. Diversify storage locations to include both on-site and off-site backups for added security.

6. Encrypt Key Information

Encryption ensures that even if your data is intercepted, it remains unreadable. Protect sensitive information like customer details, financial records, and internal communications with encryption protocols.
Implement end-to-end encryption for communications like emails and file sharing. Use encrypted storage solutions for highly sensitive data. Regularly update encryption keys to stay ahead of advancing cyber threats.

7. Limit Access to Sensitive Data

Restrict access to confidential information to only those employees who need it for their roles. Implement role-based access controls to minimise the risk of internal breaches.
Monitor user activity logs to identify unauthorised attempts to access restricted data. Conduct periodic reviews to ensure access permissions are up to date. Remove access immediately when an employee changes roles or leaves the organisation.

8. Secure Your Wi-Fi Network

A vulnerable Wi-Fi network can be an entry point for attackers. Use strong passwords, enable encryption, and hide your network's SSID to reduce exposure to cyber threats.
Set up a separate network for guests to keep your business systems secure. Regularly change your Wi-Fi password, especially after employee turnover. Use enterprise-grade encryption protocols for better protection.

9. Ensure a Strong Password Policy

Weak passwords are a common vulnerability. Encourage employees to use complex, unique passwords and change them regularly. Avoid easily guessable passwords like '123456' or 'password.'

Implement multi-factor authentication (MFA) to add an extra layer of security to accounts. Provide guidelines for creating passwords with a mix of letters, numbers, and symbols. Educate employees on the risks of reusing passwords across different platforms.

10. Use Password Managers

Password managers can help your team generate and securely store strong passwords. They also simplify the process of managing multiple passwords for different accounts.
Choose a reputable password manager with enterprise-level security features. Train employees on how to use the manager effectively and securely. Regularly review password strength reports to address any weak or compromised passwords.

11. Use a Firewall

Firewalls act as a barrier between your internal network and potential threats from the internet. Install firewalls on all devices to monitor and control incoming and outgoing traffic.
Configure your firewall settings to block unauthorised access and alert you to suspicious activity. Use both hardware and software firewalls for comprehensive protection. Regularly update your firewall software to keep up with the latest threats.

12. Use a Virtual Private Network (VPN)

A VPN encrypts your internet connection, ensuring data security when accessing public or unsecured networks. This is particularly important for remote employees or when travelling.
Choose a VPN service with a no-logs policy to improve privacy. Encourage employees to use the VPN whenever they connect to the company network remotely. Regularly test the VPN's speed and reliability to ensure uninterrupted productivity.

13. Guard Against Physical Theft

Protect physical devices like laptops, tablets, and phones with locks, alarm systems, and secure storage areas. Physical theft can lead to significant data breaches.

Label equipment to make it identifiable and less attractive to thieves. Enable device tracking and remote wipe capabilities to secure data in case of theft. Limit the use of portable devices to reduce exposure to physical loss.

14. Don’t Overlook Mobile Devices

Mobile devices are often overlooked in cybersecurity plans. Implement security measures like encryption, password protection, and remote wipe capabilities for all business-related mobile devices.
Encourage employees to update their devices regularly to patch vulnerabilities. Use mobile device management (MDM) software to enforce security policies. Train employees to avoid using public charging stations that may pose risks like juice jacking.

15. Ensure Third Parties Who Deal with You Are Also Secure

Third-party companies and collaborators can pose security risks. Assess their cybersecurity practices and establish clear guidelines for data sharing to reduce vulnerabilities in your supply chain.

Create agreements requiring external parties to follow your cybersecurity standards. Regularly review their compliance with these standards. Limit the amount of sensitive data shared with external collaborators to minimise potential exposure.

Conclusion

Protecting your small business from cyber threats is crucial in today’s digital world. By following these 15 best practices, ranging from employee training and risk assessments to installing firewalls and ensuring third-party security, you can significantly improve your business’s cybersecurity posture. Implementing these strategies will not only secure your data but also ensure smooth operations and maintain customer trust.
