October is Cyber Security Awareness Month, a timely reminder for all Australians to prioritise online safety. For small and medium-sized businesses (SMBs), the spotlight on cybersecurity has never been more crucial. 

Cyber threats are becoming increasingly sophisticated and widespread, affecting businesses of all sizes. SMBs, however, often face distinct challenges in this area. They may lack the cybersecurity maturity of larger organisations, with fewer technical defences. Despite this, the impact of a data breach or cyber-attack can be just as severe. Such incidents can disrupt operations, damage customer trust, and result in financial penalties under regulations like the Australian Privacy Act. 

Given these realities, it’s essential for small and medium businesses to take proactive steps to bolster their cybersecurity defences.  

Practical cybersecurity measures for SMBs  

Here are some practical, cost-effective measures that can make a real difference: 

1. Educate and train your employees 

Human error remains one of the biggest cybersecurity risks for businesses. Many cyberattacks, such as phishing scams, exploit employees’ lack of awareness or vigilance. By investing in cybersecurity training, businesses can significantly reduce this risk. 

Start by educating your employees on how to identify common threats, such as suspicious emails or fake websites. Ensure they understand the importance of using strong, unique passwords and two-factor authentication (2FA) to protect sensitive accounts.  

The Australian Cyber Security Centre (ACSC) offers free training resources you can use to educate your team members on the basics. 

2. Implement Multi-Factor Authentication (MFA) 

One of the simplest and most effective ways to protect sensitive systems is by using Multi-Factor Authentication (MFA). With MFA, users must provide two or more verification methods before accessing an account, making it much harder for hackers to gain access. 

According to the ACSC, businesses that use MFA reduce their risk of compromise by over 80%. Implement MFA on all critical systems, such as email accounts, financial software, and customer databases. 

3. Regular software updates 

Outdated software is a common entry point for cybercriminals. Many attacks exploit known vulnerabilities in software that has not been updated. Ensure all your systems, applications, and devices are regularly updated and patched to the latest versions. 

For businesses with limited IT, enabling automatic updates can help mitigate the risk of missed updates. Additionally, regularly review any third-party applications you use to ensure they are still secure and necessary. 

4. Back up your data regularly 

Data breaches and ransomware attacks can be catastrophic for SMBs. A strong data backup plan can ensure that even if you are attacked, your business can recover with minimal disruption. In 2023, the ACSC reported that ransomware attacks increased by 15% in Australia. 

Make sure to back up critical data regularly, and store backups in a separate location from your primary systems. Test these backups periodically to confirm they work as expected. 

5. Develop a Cybersecurity Incident Response Plan 

Even with the best defences in place, no business is entirely immune to cyberattacks. Preparing for the worst is crucial. Developing a cybersecurity incident response plan can help your business respond quickly and effectively to any incidents. 

This plan should include clear steps for identifying, containing, and mitigating an attack, as well as guidelines for reporting incidents to the ACSC and affected customers if necessary. Having a well-practiced plan in place can limit the impact of a cyber incident on your business. 

6. Use strong, unique passwords  

Weak or reused passwords are a major risk factor for SMBs. Cybercriminals often use automated tools to crack simple passwords or leverage previously leaked credentials from one service to access another. 

Encourage your team to use long, complex passwords, and consider implementing a password manager. A password manager can generate and store unique passwords for all business accounts, reducing the likelihood of compromise.

Cybersecurity is no longer an option but a necessity for Australian small and medium businesses. As cybercriminals continue to evolve their tactics, SMBs must stay vigilant and proactive in protecting their digital assets. This Cyber Security Awareness Month, take the time to assess your current practices and implement these simple but effective steps to safeguard your business. 

By doing so, you’ll not only protect your business but contribute to a safer online environment for all Australians.
