Regular network security audits are an important part of keeping your business's IT systems safe and running smoothly. Simply put, these audits are thorough checks of your network's security setup to find weaknesses before cybercriminals do. For an Australian small or mid-sized business, this means identifying risks like outdated software, misconfigured devices, or weak access controls that could lead to data breaches or system downtime.
Why this matters for Australian SMBs
Cyber threats are constantly evolving, and small businesses often face similar risks as larger companies but with fewer resources to respond. A security gap in your network could result in lost customer data, interrupted operations, or damage to your reputation. For example, if your network is compromised, you might experience costly downtime while systems are restored, or worse, face regulatory scrutiny if customer information is exposed. Regular audits help minimise these risks by ensuring your defences are up to date and effective.
A practical example
Consider a typical Australian business with 50 employees using cloud services, local servers, and Wi-Fi networks. Without regular security reviews, they might unknowingly have outdated firewall rules or default passwords still active on some devices. A managed IT provider conducting a network security audit would identify these issues, recommend immediate fixes, and implement ongoing monitoring. This proactive approach helps prevent incidents that could disrupt business and erode customer trust.
What to check and ask
- Ask your IT provider: How often do you perform network security audits? What standards or frameworks do you follow (e.g., Australian Cyber Security Centre guidelines)?
- Review your current setup: Check if software and firmware on all network devices are up to date and patched regularly.
- Access controls: Verify that user access is limited to what's necessary, and that strong password policies or multi-factor authentication are in place.
- Backup verification: Ensure backups are running correctly, stored securely, and tested for recovery.
- Incident response: Confirm your provider has a clear plan for responding to security incidents discovered during audits.
- Audit frequency: Aim for at least annual audits, or more frequently if your business handles sensitive data or faces higher risk.
Next steps
Regular network security audits are a practical way to protect your business from avoidable risks. If you don't have a current audit schedule, speak with a trusted managed IT provider or IT advisor who understands the needs of Australian small and mid-sized businesses. They can help tailor an audit and ongoing security strategy that fits your budget and operational requirements.
