What is a Cyber Security Audit Checklist?
A Cyber Security Audit Checklist is a tool for assessing the security posture of an organisation’s IT systems, networks, and data. Its purpose is to evaluate how well a business is protected against cyber threats and ensure that it adheres to security best practices, compliance standards, and regulatory requirements.
A thorough cyber security audit involves reviewing your company’s infrastructure, policies, and procedures to pinpoint vulnerabilities, assess cyber security risks, and identify weaknesses. This process helps organisations understand their current cyber security status, make informed decisions for improvements, and reduce the likelihood of cyber incidents like data breaches, hacking, or ransomware.
What are the Types of Cyber Security Audits
1. Compliance Audit
A compliance audit evaluates whether an organisation adheres to regulatory requirements, industry standards, and internal policies. It focuses on ensuring that systems, processes, and data handling practices align with specific frameworks, such as:
- The Privacy Act 1988 (Australia)
- ISO/IEC 27001
- General Data Protection Regulation (GDPR)
2. Vulnerability Assessment
A vulnerability assessment identifies weaknesses in your IT systems that attackers could exploit. This audit involves scanning your network, applications, and devices to uncover misconfigurations, outdated software, and other security gaps.
Cybercriminals constantly look for vulnerabilities to exploit. A vulnerability assessment allows businesses to proactively address these gaps, reducing the likelihood of breaches or ransomware attacks.
3. Penetration Testing
Penetration testing (or ethical hacking) simulates real-world cyberattacks to evaluate the strength of your security defences. Unlike a vulnerability assessment, penetration testing involves actively exploiting identified weaknesses to assess their impact.
This type of audit provides valuable insights into how well your systems can withstand an attack, enabling you to strengthen defences before an actual breach occurs.
Cyberattacks can happen at any time. Contact us today for a thorough cybersecurity audit and peace of mind, knowing your business is secure against evolving threats.
4. Risk Assessment Audit
A risk assessment audit identifies potential threats to your organisation’s IT systems and evaluates the likelihood and impact of those risks. This audit goes beyond technical vulnerabilities to consider operational, strategic, and compliance risks. Understanding risks allows businesses to prioritise effective security controls to protect and allocate resources effectively. It’s an essential step in developing a robust risk management strategy.
Key components:
- Identifying critical assets and their associated risks
- Assessing the probability and potential impact of threats
- Recommending controls to mitigate identified risks
- Creating a risk management plan to address current and future challenges

Cyber Security Audit Checklist for the Protection of Your Business
1. Review Your Security Policies
A strong cyber security policy is the backbone of an effective defence strategy. It outlines how data is handled, accessed, and secured within the organisation. During the review, ensure that policies are clear, up-to-date, and enforceable. They should address password management, acceptable use of IT resources, data classification, and procedures for handling the event of a security breach. Policies should also comply with relevant Australian laws, such as the Privacy Act 1988, ensuring legal and regulatory alignment.
2. Evaluate Network Security
Network security is critical as it serves as the first line of defence against external threats. Review your firewalls to confirm they are properly configured and actively blocking malicious traffic. Check for intrusion detection and prevention systems (IDS/IPS) to identify and halt unusual activity. Regularly patch and update network hardware and software to protect your business against known vulnerabilities. Also, remote access solutions like virtual private networks (VPNs) should be evaluated to ensure secure connections for remote employees.
3. Describe Access Controls
Access control mechanisms protect sensitive information by limiting who can access systems and resources. Evaluate your access controls to ensure employees only have the permissions needed for their roles. Implement multi-factor authentication (MFA) for accessing critical systems to add an extra security layer. Conduct periodic reviews of user access rights and immediately revoke access for employees who leave the company or change roles.
4. Test Data Encryption
Encryption ensures that sensitive data remains protected even if intercepted. During your audit, review encryption protocols for both data at rest (stored data) and data in transit (data transferred between systems). Ensure your encryption methods align with industry standards and comply with Australian regulations. Regularly test encryption systems to identify vulnerabilities and ensure sensitive customer and business data remains secure.

5. Follow Backup Procedures
A reliable data backup strategy is crucial for the continuity of business operations in the event of cyber incidents, including ransomware attacks. Develop a clear backup plan that specifies how often critical data is backed up—ideally daily or more frequently. Store backups in multiple locations, including offsite and cloud storage, to ensure accessibility and security. Regularly test your backup restoration process to ensure data can be recovered quickly in case of emergencies, reducing downtime and financial impact.
6. Conduct Regular Security Training
Your employees can often be the weakest link in your cyber security defences. Regular cyber security training is essential to help them identify phishing attacks, create strong passwords, and handle sensitive data securely. Implement simulations to assess their ability to detect threats and foster a culture of proactive cyber security awareness across the organisation.
7. Implement and Maintain Firewalls
Firewalls act as digital barriers, preventing unauthorised access to your network. During your audit, confirm that firewalls are properly configured and up-to-date. Use advanced settings to block suspicious traffic while allowing legitimate business communication. Regular maintenance ensures your firewalls remain effective in the face of evolving threats.
8. Monitor Network Traffic
Monitoring network traffic is essential for detecting anomalies that may indicate cyber threats. Use network monitoring tools to identify and address unusual patterns or unauthorised access attempts. Segment networks to minimise the impact of breaches and isolate critical systems.
9. Develop an Incident Response Plan
An incident response plan prepares your organisation for potential cyberattacks. Clearly define roles and responsibilities for handling breaches, containment, and recovery. Test the plan regularly with simulated scenarios to ensure it works effectively and is updated to reflect new threats.
10. Conduct Penetration Testing
Penetration testing simulates cyber attacks to uncover vulnerabilities in your systems. Conduct both internal and external tests to evaluate how well your defences hold up against different attack methods. Use the findings to prioritise and address weaknesses, improving your organisation’s security posture.
11. Perform Audits Periodically
Cyber threats evolve rapidly, so cyber security audits should be a recurring task. Conduct full-scale audits at least annually and perform mini-audits whenever there are major changes in IT systems or after a security incident. Periodic audits ensure that your cyber security measures remain effective, enabling businesses to adapt to new threats and maintain a strong security posture.
How often should you conduct a cyber security audit?
Cyber Security audits should typically occur at least once a year. However, businesses in high-risk sectors like finance or healthcare may need more frequent assessments, such as quarterly reviews. Additionally, audits should follow significant changes in IT infrastructure or after experiencing a cyber incident.
12. Review Third-Party Vendor Security
Third-party vendors often have access to sensitive data or systems, making their security practices a critical concern. Assess their compliance with industry standards, such as ISO 27001 or Australian privacy laws. Review contracts to ensure they include clauses on data protection and incident reporting. Regularly request security certifications, audit reports, or questionnaires to verify their cyber security measures. Establish a vendor risk management program to monitor and address third-party vulnerabilities continuously.
13. Implement a Mobile Device Management Policy
With the rise of mobile and remote work, securing devices like smartphones, tablets, and laptops is crucial. Implement a Mobile Device Management (MDM) policy to enforce security protocols, such as password requirements, device encryption, and remote wipe capabilities for lost or stolen devices. Ensure that only authorised devices connect to company networks and that employees update operating systems and applications regularly to reduce vulnerabilities.

14. Develop a Business Continuity and Disaster Recovery Plan
A Business Continuity and Disaster Recovery (BCDR) plan ensures operations can resume quickly after a cyber incident. Outline strategies for data restoration, system recovery, and operational continuity. Identify critical systems and prioritise their recovery to minimise downtime. Include alternative communication methods and designate roles for crisis management. Regularly test the plan with simulated scenarios to confirm its effectiveness and make adjustments based on evolving risks.
15. Deploy Email Security Measures
Email remains a primary attack vector for phishing and malware. Strengthen email security by implementing spam filters, advanced threat protection, and Domain-based Message Authentication, Reporting, and Conformance (DMARC) protocols. Educate employees on recognising suspicious emails and avoiding harmful links or attachments. Regularly review email logs to detect unauthorised access or suspicious activities. These measures significantly reduce the risk of email-based attacks compromising your systems.
How Long Does a Cyber Security Audit Take?
The duration of a cybersecurity audit depends on the size and complexity of your IT environment. For small to medium-sized businesses, it typically takes 2–5 days. Larger organisations with more intricate systems may require several weeks. The timeline also varies based on the scope of the audit, such as whether it includes compliance checks, vulnerability assessments, or penetration testing.
