Network Security Audit

This audit evaluates your network infrastructure firewalls, routers, switches, and segmentation.

Focus Areas: Firewall rules, intrusion detection/prevention systems (IDPS), and network segmentation.
Action Tip: Schedule quarterly reviews of firewall configurations and test IDPS effectiveness using simulated attacks.

Application Security Audit

With software powering most business operations, this audit checks for vulnerabilities in web and mobile apps.

Focus Areas: Source code reviews, vulnerability scans, and patch management.
Action Tip: Use automated tools like OWASP ZAP or Burp Suite to scan for common flaws like SQL injection and XSS.

Cloud Security Audit

As cloud adoption grows, so does the need to secure cloud environments.

Focus Areas: Access controls, data encryption, vendor compliance, and misconfiguration risks.
Action Tip: Implement role-based access controls (RBAC) and regularly audit cloud storage permissions.

Compliance Audit

These audits ensure adherence to standards like ISO 27001, GDPR, or Australia’s Essential Eight.

Focus Areas: Policy documentation, incident response plans, and regulatory alignment.
Action Tip: Maintain a compliance calendar to track audit deadlines and regulation updates.

Operational Security Audit

This audit reviews day-to-day security practices and employee behaviour.

Focus Areas: Password hygiene, device usage, and access provisioning.
Action Tip: Conduct regular phishing simulations and enforce multi-factor authentication (MFA) across all accounts.

Penetration Testing (Ethical Hacking)

Simulated attacks reveal real-world vulnerabilities before malicious actors do.

Focus Areas: External and internal attack vectors, social engineering, and privilege escalation.
Action Tip: Hire certified ethical hackers annually and prioritise remediation based on risk severity.

Configuration Audit

Misconfigured systems are low-hanging fruit for attackers.

Focus Areas: Server settings, endpoint security, and patch levels.
Action Tip: Use tools like CIS-CAT or Microsoft Security Compliance Toolkit to benchmark configurations against best practices.

Build an Integrated Audit Framework to maximise impact

Audit Frequency: Tailor to your risk profile, high-risk sectors may need monthly checks.
Documentation: Keep detailed records for accountability and future audits.
Continuous Improvement: Treat audits as iterative, not one-off events.

As we wrap up 2025 and prepare for the challenges and opportunities of the new year, now is the time to embed cybersecurity audits into your strategic roadmap. Think of them not as one-off tasks, but as continuous safeguards that evolve with your business.

By investing in a layered audit framework today, you’ll enter 2026 with greater confidence, resilience, and readiness to face whatever the digital world throws your way.
