Top 10 cybersecurity mistakes small businesses make (and how to avoid them)

Cybersecurity is no longer a concern limited to large enterprises. According to the UK Government’s 2023 Cyber Security Breaches Survey, 39% of small businesses reported cyberattacks in the past year, with many resulting in data loss or operational disruption. Small businesses are increasingly targeted due to weaker defences. This article highlights the top 10 mistakes businesses make and practical steps to avoid them.

1. Neglecting cybersecurity awareness training

Lack of training leaves employees vulnerable to phishing, ransomware, and other attacks. A startling 88% of data breaches are caused by human error. Many employees unknowingly compromise security by clicking on malicious links or sharing sensitive information.

Solution: Invest in regular employee training programmes. Managed cybersecurity services like DarkShield’s solutions can provide ongoing training and support to keep your team informed.

2. Using weak or reused passwords

Weak passwords are easy targets for hackers using brute-force attacks. The 2023 Verizon Data Breach Investigations Report revealed that 61% of breaches involved stolen or weak credentials.

Solution: Enforce strong password policies and enable multi-factor authentication (MFA). Use password managers to create and store unique passwords for all accounts.

3. Skipping vulnerability assessments

Failing to identify and patch vulnerabilities exposes businesses to unnecessary risks. Cybercriminals often exploit unpatched systems to gain access.

Solution: Conduct regular vulnerability assessments to uncover weaknesses and address them proactively.

4. Ignoring phishing threats

Phishing attacks trick employees into revealing credentials or downloading malware. These attacks accounted for 43% of reported cyber incidents in the UK last year.

Solution: Implement robust email filtering systems and conduct simulated phishing tests to educate employees about recognising fraudulent emails.

5. Failing to back up critical data

Many businesses fail to back up their data effectively, leaving them vulnerable to ransomware and data loss. Only 70% of UK businesses regularly back up their data.

Solution: Automate daily backups and store copies in secure off-site locations or the cloud. Test backups periodically to ensure they are recoverable.

6. Skipping penetration testing

Many small businesses assume they are not at risk and skip penetration testing, which helps identify weaknesses before cybercriminals do.

Solution: Conduct regular penetration tests to evaluate your defences and identify potential vulnerabilities.

7. Lacking an incident response plan

A delayed response to a cyberattack can significantly increase damage. Unfortunately, 75% of small businesses lack an incident response strategy.

Solution: Create a comprehensive response plan detailing steps to contain, mitigate, and recover from cyberattacks. Consider incident response services for expert guidance.

8. Ignoring cybersecurity compliance

Failure to comply with regulations like GDPR can result in hefty fines and reputational damage. Small businesses often overlook compliance, assuming it’s irrelevant to them.

Solution: Stay updated with cybersecurity regulations by reviewing resources like our guide on UK cybersecurity laws.

9. Relying solely on antivirus software

While antivirus software provides basic protection, it is not sufficient to combat modern threats. Cybercriminals use sophisticated techniques that require layered defences.

Solution: Enhance security with firewalls, intrusion detection systems, and continuous monitoring through managed cybersecurity services.

10. Underestimating insider threats

Insider threats, whether malicious or accidental, can be just as damaging as external attacks. Studies show that 34% of cyber incidents involve insider actions.

Solution: Implement strict access controls, monitor employee activities, and use advanced tools to detect suspicious behaviour.
