Why Australian Businesses Must Prioritise Cybersecurity
Australia is increasingly targeted by cybercriminals. The Australian Cyber Security Centre (ACSC) reports that cybercrime costs Australian businesses billions annually, with small and medium businesses often the most vulnerable targets.
This guide covers essential cybersecurity best practices every Australian business should implement to protect their data, customers, and reputation.
The Essential Eight Framework
The ACSC’s Essential Eight is the baseline cybersecurity framework recommended for Australian organisations. While originally designed for government agencies, these strategies are valuable for any business:
1. Application Control
Only allow approved applications to run on your systems. This prevents malware and unauthorised software from executing.
2. Patch Applications
Keep all software updated with the latest security patches. Unpatched software is one of the most common entry points for attackers.
3. Configure Microsoft Office Macro Settings
Disable or restrict macros in Office documents – they’re a common way malware is delivered.
4. User Application Hardening
Configure web browsers and other applications to block malicious content like Flash, ads, and Java.
5. Restrict Administrative Privileges
Limit admin access to only those who need it. Most users should work with standard accounts.
6. Patch Operating Systems
Keep Windows, macOS, and other operating systems updated with security patches.
7. Multi-Factor Authentication (MFA)
Require MFA for all remote access and privileged accounts. This single control stops the majority of account compromise attacks.
8. Regular Backups
Maintain regular, tested backups stored separately from your main network. This is your last line of defence against ransomware.
Additional Security Best Practices
Email Security
Email is the primary attack vector for most businesses. Implement:
- Spam and phishing filters
- Email authentication (SPF, DKIM, DMARC)
- Link and attachment scanning
- User awareness training
Security Awareness Training
Your employees are your first line of defence – and potentially your biggest vulnerability. Regular training helps staff:
- Recognise phishing emails
- Handle sensitive data properly
- Report suspicious activity
- Follow security policies
Network Security
- Use business-grade firewalls
- Segment your network to limit breach impact
- Secure Wi-Fi with strong encryption
- Monitor network traffic for anomalies
Endpoint Protection
- Deploy enterprise antivirus/anti-malware
- Enable device encryption
- Implement mobile device management (MDM)
- Monitor endpoints for threats
Incident Response Planning
Despite best efforts, breaches can happen. Having an incident response plan means you can:
- Detect incidents quickly
- Contain the damage
- Recover operations faster
- Meet notification obligations
Australian Privacy Obligations
The Privacy Act 1988 and Notifiable Data Breaches (NDB) scheme require Australian businesses to:
- Protect personal information with reasonable security
- Notify affected individuals and the OAIC of eligible data breaches
- Have a privacy policy explaining data handling practices
