10 Cyber security best practices for small businesses

In the ever-evolving world of technology, cybersecurity has become a top priority for businesses of all sizes. However, small businesses often find themselves particularly vulnerable to cyber threats due to limited resources and expertise. According to the UK Government’s Cyber Security Breaches Survey 2023, 39% of small businesses identified a cyber attack in the past year. Implementing robust cybersecurity measures is not just a technical necessity but a strategic imperative. Here are ten best practices to bolster your small business’s cybersecurity.

1. Implement strong password policies

Passwords are the first line of defence against cyber threats. Yet, many small businesses still use weak or easily guessable passwords. According to Verizon’s 2023 Data Breach Investigations Report, 81% of hacking-related breaches leveraged either stolen or weak passwords.

To enhance security, implement a strong password policy that requires employees to use complex passwords, combining upper and lower case letters, numbers, and special characters. Encourage the use of password managers like LastPass or 1Password, which can generate and store complex passwords securely. Additionally, enforce regular password changes and avoid password reuse across different accounts.

2. Enable two-factor authentication (2FA)

Two-factor authentication (2FA) adds an extra layer of security by requiring a second form of verification in addition to a password. This could be a text message code, an authentication app, or biometric verification like a fingerprint.

Enabling 2FA can significantly reduce the risk of unauthorised access. According to Microsoft, 99.9% of account compromise attacks can be blocked by using multi-factor authentication. Implement 2FA across all critical systems and services, including email, cloud storage, and financial accounts, to enhance your security posture.

3. Regularly update software and systems

Keeping your software and systems up to date is crucial for protecting against vulnerabilities that cybercriminals can exploit. According to the Ponemon Institute’s 2023 State of Cybersecurity report, 60% of data breaches involved unpatched vulnerabilities.

Ensure that all operating systems, applications, and firmware are regularly updated with the latest security patches. Enable automatic updates wherever possible to minimise the risk of missing critical patches. Additionally, maintain an inventory of all software and hardware assets to track updates and ensure nothing is overlooked.

4. Educate employees about cybersecurity

Your employees are often the weakest link in your cybersecurity chain. Cybercriminals frequently use social engineering tactics, such as phishing, to trick employees into revealing sensitive information. According to a report by PhishMe, 91% of cyber attacks begin with a phishing email.

Invest in regular cybersecurity training for your employees to raise awareness about common threats and best practices. Training should cover recognising phishing emails, safe internet browsing habits, and the importance of reporting suspicious activities. Foster a culture of security awareness, making it clear that cybersecurity is everyone’s responsibility. For more on this topic, explore 10 Problems a Fractional CTO Can Solve for SMBs.

5. Use antivirus and anti-malware software

Antivirus and anti-malware software are essential tools for detecting and preventing malicious attacks on your systems. According to AV-Test, over 560,000 new pieces of malware are detected every day, underscoring the need for robust protection.

Choose reputable antivirus software and ensure it is installed on all devices, including desktops, laptops, and mobile devices. Regularly update the software to protect against the latest threats. Additionally, consider using endpoint protection solutions that provide comprehensive security for all endpoints connected to your network.

6. Secure your network

A secure network is fundamental to protecting your business data. Implement strong security measures such as firewalls, virtual private networks (VPNs), and secure Wi-Fi networks. According to a report by Cybersecurity Ventures, the global cost of cybercrime is expected to reach $10.5 trillion annually by 2025, making network security more critical than ever.

Configure your firewall to block unauthorised access and monitor incoming and outgoing traffic for suspicious activity. Use a VPN to encrypt data transmitted over public or unsecured networks, especially when employees are working remotely. Ensure your Wi-Fi networks are secured with strong passwords and WPA3 encryption, and consider setting up a separate guest network to isolate business data from external devices.

7. Backup data regularly

Regular data backups are essential for mitigating the impact of a cyber attack, such as ransomware. According to the University of Maryland, a cyber attack occurs every 39 seconds, highlighting the importance of having a reliable backup strategy.

Implement a robust backup plan that includes regular, automated backups of all critical data. Store backups in multiple locations, including offsite and cloud-based storage, to ensure data redundancy. Test your backup and recovery processes periodically to verify that data can be restored quickly and accurately in the event of an incident.

8. Implement access controls

Controlling who has access to your systems and data is crucial for reducing the risk of insider threats and unauthorised access. According to the 2023 Verizon Data Breach Investigations Report, 30% of data breaches involved internal actors.

Implement the principle of least privilege (PoLP), which means giving employees the minimum level of access necessary to perform their job functions. Use role-based access controls (RBAC) to manage permissions and regularly review access rights to ensure they are appropriate. Additionally, implement logging and monitoring to track user activities and detect any suspicious behaviour. Enhance your security measures by exploring our Security Monitoring Services.

9. Develop an incident response plan

Despite your best efforts, cyber incidents can still occur. Having an incident response plan in place ensures that your business can respond quickly and effectively to minimise damage. According to IBM’s 2023 Cost of a Data Breach Report, the average cost of a data breach is $4.45 million, but having an incident response plan can reduce this cost by up to $1.23 million.

Your incident response plan should outline the steps to take in the event of a cyber incident, including identifying and containing the threat, notifying affected parties, and recovering data and systems. Assign roles and responsibilities to team members and conduct regular drills to ensure everyone is familiar with the plan. Keep the plan updated to address emerging threats and changes in your business operations. To strengthen your incident response strategy, consider our Cybersecurity Services.

10. Monitor and audit systems

Continuous monitoring and auditing of your systems are essential for detecting and responding to potential security threats. According to a report by the SANS Institute, 40% of organisations detected security incidents through continuous monitoring.

Implement security information and event management (SIEM) solutions to collect and analyse security data in real-time. Regularly audit your systems and processes to identify vulnerabilities and ensure compliance with security policies and regulations. Monitoring and auditing help maintain a proactive security posture, allowing you to address issues before they escalate into major incidents.
