Top 25 Cybersecurity Tips for Small Businesses

Running a small business is a real achievement, but it also comes with responsibilities, and one of the most important things you can do to keep your business running smoothly is keeping your data and systems secure.

Cybersecurity can seem daunting, but it doesn't have to be. We share 25 practical tips to help you protect your small business from cyber threats. Think of it as a checklist to strengthen your defences and give you peace of mind.

Building a Strong Foundation

Let's start with some fundamental principles that form the bedrock of good cyber security.

1. Strong and Unique Passwords

This might seem obvious, but it's surprising how many people still use weak or easily guessed passwords. Use a mix of upper and lowercase letters, numbers, and symbols. Don't use the same password for multiple accounts. A password manager can help you generate and store strong, unique passwords. Check out the National Cyber Security Centre (NCSC) guidance for more tips.

2. Multi-Factor Authentication (MFA)

MFA adds an extra layer of security. Even if someone manages to guess your password, they'll need a second form of verification, like a code sent to your phone, to access your account. Enable MFA wherever possible.

3. Keep Software Updated

Regular software updates patch security vulnerabilities that cybercriminals can exploit. Make sure your operating systems, applications, and antivirus software are always up to date. Enable automatic updates where possible.

4. Install Antivirus and Anti-Malware Software

Antivirus and anti-malware software scans your systems for malicious code and helps to prevent infections. Choose a reputable provider and keep your software up to date.

5. Regular Backups

Backups are your safety net. If your systems are compromised, you can restore your data from a recent backup. Follow the 3-2-1 rule: three copies of your data, on two different storage types, with one copy stored offsite (e.g., in the cloud).

Protecting Your Network

Your network is the gateway to your business's data, so it's essential to keep it secure.

6. Secure Your Wi-Fi Network

Use a strong password for your Wi-Fi network and consider setting up a separate guest network for visitors. This helps to protect your business data from unauthorised access.

7. Firewall Protection

A firewall acts as a barrier between your network and the outside world, blocking unauthorised access. Make sure your firewall is properly configured and enabled.

8. Virtual Private Network (VPN)

A VPN creates a secure connection for remote access to your network. This is particularly important if employees are working from home or accessing sensitive data from public Wi-Fi networks.

9. Monitor Network Activity

Keep an eye on your network activity for any suspicious behaviour. There are tools available that can help you monitor network traffic and identify potential threats.

10. Segment Your Network

Segmenting your network means dividing it into smaller, isolated sections. This can help to limit the impact of a cyber attack, as it prevents the attacker from accessing your entire network.

Email and Communication Security

Email is a common vector for cyber attacks, so it's important to be cautious.

11. Be Wary of Phishing Emails

Phishing emails try to trick you into revealing sensitive information, like passwords or bank details. Be suspicious of emails from unknown senders and never click on links or open attachments in emails that you weren't expecting.

12. Don't Click Suspicious Links

Avoid clicking on links in emails, text messages, or social media posts that look suspicious. It's always better to type the website address directly into your browser.

13. Secure Email Accounts

Use strong passwords for your email accounts and enable MFA where possible. Consider using a separate email account for business and personal use.

14. Encrypt Sensitive Emails

If you're sending sensitive information via email, encrypt it to protect it from unauthorised access.

15. Be Careful with Attachments

Be cautious about opening attachments from unknown senders. Malicious code can be hidden in attachments.

Protecting Your Data

Your data is one of your most valuable assets, so it's vital to protect it.

16. Data Encryption

Encrypting your data makes it unreadable to anyone who doesn't have the decryption key. This is an important step in protecting sensitive information.

17. Access Control

Limit access to sensitive data to only those employees who need it. Use strong passwords and access controls to restrict unauthorised access.

18. Secure Data Storage

Store your data in a secure location, whether it's on your local network or in the cloud. Make sure your storage systems are protected by strong passwords and access controls.

19. Data Disposal

When you dispose of old computers or storage devices, make sure you wipe the data completely. Simply deleting files is not enough.

20. Comply with Data Protection Regulations

Make sure you're aware of and comply with relevant data protection regulations, such as the General Data Protection Regulation (GDPR).

Staff Training and Awareness

Your employees are your first line of defence against cyber attacks.

21. Cyber Security Awareness Training

Provide regular cyber security awareness training to your employees. Teach them about phishing, password security, and other common threats.

22. Clear Cyber Security Policies

Develop clear cyber security policies and procedures and make sure your employees are aware of them.

23. Incident Response Plan

Have an incident response plan in place in case of a cyber attack. This will help you to respond quickly and effectively.

24. Regular Security Audits

Conduct regular security audits to identify any weaknesses in your systems and procedures.

25. Stay Informed

Stay up to date with the latest cyber security threats and best practices. Follow cyber security blogs and newsletters, and attend webinars or conferences. The NCSC website is a great resource for staying informed.
