Top 10 cybersecurity threats for SMBs

Cybersecurity is a very real concern for SMBs, with cyber threats becoming increasingly sophisticated and frequent. While large enterprises often dominate the headlines when it comes to cyber-attacks, SMBs are equally at risk, often lacking the robust defences that bigger corporations have in place.

Here, we dive deep into the top ten cybersecurity threats facing SMBs today, providing insights into how you can protect your business. For additional strategies on cybersecurity, you can also explore our 10 Cyber security best practices for small businesses.

1. Phishing attacks

Phishing attacks remain one of the most common and damaging cybersecurity threats for SMBs. These attacks typically involve malicious emails that appear to be from trusted sources, tricking employees into revealing sensitive information or downloading malware. According to the Cyber Security Breaches Survey 2023, 83% of UK businesses experienced phishing attacks last year.

To combat phishing, it's crucial to educate employees about recognising suspicious emails and implementing robust email security solutions. Regular training and simulated phishing exercises can significantly reduce the risk. For a deeper understanding of how external threats can affect your business and the importance of cyber vigilance, refer to our article on the Top 10 cybersecurity threats for SMBs.

2. Ransomware

Ransomware is a type of malware that encrypts a victim’s data, demanding payment in exchange for the decryption key. SMBs are often targeted because they are perceived as having weaker security measures. In 2023, the average ransom demand from SMBs was £64,000, according to a report by Sophos.

To mitigate ransomware risks, regularly back up your data and ensure backups are stored offline or in a secure cloud environment. Implementing advanced endpoint protection and keeping all software up-to-date are also vital steps. If you're exploring cost-effective ways to safeguard your business, consider the tools and techniques discussed in Top 5 sustainable software tools for lean startups, as some sustainable practices also enhance security.

3. Insider threats

Insider threats involve malicious or negligent actions by employees or other internal stakeholders. These threats can be particularly damaging because insiders often have access to sensitive information and systems. According to Verizon’s Data Breach Investigations Report 2023, 22% of data breaches involved insiders.

Mitigating insider threats requires a combination of robust access controls, regular audits, and fostering a culture of security awareness. Tools that monitor user activity and detect unusual behaviour can also be valuable. To tackle insider risks effectively, the involvement of a fractional CTO can be beneficial.

4. Malware

Malware, which includes viruses, worms, and spyware, can infiltrate SMB systems through various vectors, such as email attachments, malicious websites, or compromised software. Malware can steal data, disrupt operations, or provide hackers with backdoor access to your systems.

Comprehensive cybersecurity measures, including antivirus software, firewalls, and intrusion detection systems, are essential for defending against malware. Regularly updating all software and educating employees about safe browsing practices can further reduce risks. A strategic approach to software development can also include implementing eco-friendly coding practices, which can often be more secure. Learn more in our article on 10 Eco-friendly coding practices for SMBs to reduce costs.

5. Weak passwords

Weak or easily guessable passwords remain a significant security vulnerability for SMBs. Cybercriminals use techniques like brute force attacks to crack passwords and gain unauthorised access to systems. The 2023 Verizon report noted that 81% of hacking-related breaches involved weak or stolen passwords.

Implementing strong password policies, requiring multi-factor authentication (MFA), and using password management tools can greatly enhance password security. Encourage employees to create complex passwords and change them regularly. Additionally, exploring advanced engineering techniques can help in securing your systems. Refer to 10 Advanced engineering techniques to optimise your MVP for more insights.

6. Distributed Denial of Service (DDoS) attacks

DDoS attacks aim to overwhelm a network, server, or website with a flood of traffic, rendering it unavailable to users. These attacks can disrupt business operations and lead to significant financial losses. In 2023, UK SMBs reported a 34% increase in DDoS attacks compared to the previous year, according to the UK Government's Cyber Security Breaches Survey.

To defend against DDoS attacks, invest in DDoS protection services and ensure your network infrastructure is resilient. Having a comprehensive incident response plan can also help mitigate the impact of an attack and restore normal operations more quickly. For tailored cybersecurity services, partnering with a specialised provider like the Best software agency UK can be invaluable.

7. Social engineering

Social engineering involves manipulating individuals into divulging confidential information. This can include tactics such as pretexting, baiting, and tailgating. Cybercriminals exploit human psychology rather than technical vulnerabilities, making these attacks particularly challenging to counter.

Education and training are the most effective defences against social engineering. Regularly update employees on the latest tactics used by cybercriminals and conduct simulations to reinforce training. Encouraging a culture of scepticism and verification can help prevent these attacks.

8. Cloud security threats

As more SMBs move their operations to the cloud, they face new security challenges. Misconfigured cloud settings, inadequate access controls, and vulnerabilities in cloud applications can expose sensitive data to cybercriminals. According to a 2023 report by Check Point, 27% of UK businesses experienced cloud-related security incidents.

To secure your cloud environment, ensure proper configuration and regularly review access controls. Use encryption for data at rest and in transit, and choose reputable cloud service providers that offer robust security measures. Implementing continuous monitoring can also help detect and respond to threats promptly. Cloud security can be complex, so seeking expert assistance can be beneficial.

9. Mobile device vulnerabilities

With the rise of remote work and bring-your-own-device (BYOD) policies, mobile device security has become a critical concern for SMBs. Mobile devices can be vulnerable to malware, phishing, and other cyber threats. A 2023 survey by Bitdefender found that 35% of UK SMBs experienced security incidents involving mobile devices.

Implementing mobile device management (MDM) solutions can help secure mobile devices by enforcing security policies, managing apps, and protecting data. Educate employees about the risks of using personal devices for work and encourage the use of secure connections and VPNs.

10. IoT security threats

The proliferation of Internet of Things (IoT) devices in business environments has introduced new security risks. IoT devices often lack robust security features, making them easy targets for cyber-attacks. Gartner's 2023 report highlighted that 25% of cyber-attacks in the UK involved IoT devices.

Securing IoT devices requires a multi-layered approach. Ensure that all devices are configured securely, regularly updated, and monitored for unusual activity. Segmenting IoT devices from your main network can also help contain potential breaches. Integrating security practices with software development is key.
