In an era when online dangers lurk around every virtual corner, protecting your organisation’s assets has become an existential necessity. Cybersecurity audits are like health check-ups for your IT infrastructure, ensuring it’s robust, resilient, and ready to fend off cyber threats.

Cybersecurity breaches are not just a possibility but a looming inevitability, with studies showing that Global cybercrime costs are expected to reach $10.5 trillion annually by 2025. This underscores the critical importance of cybersecurity audits in safeguarding your organisation’s digital infrastructure.

However, simply admitting the importance of cybersecurity audits is insufficient; firms must take a proactive approach to strengthen their defences against an ever-changing spectrum of cyber attacks. Organisations may remain ahead of the curve and reduce their vulnerability to cyber-attacks by adopting cybersecurity audits as a proactive rather than reactive measure. In this post, we’ll look at the many benefits of cybersecurity audits and why they’re so important in today’s company world.

What is a Cybersecurity audit?

A cybersecurity audit is a comprehensive assessment of an organisation’s information systems, policies, processes, and controls to detect vulnerabilities, assess risks, and assure adherence to regulatory standards and industry best practices.

Unlike traditional financial audits, which focus on monetary assets, cybersecurity audits delve into the realm of digital assets, encompassing a wide array of technological components and processes.

Cybersecurity audits examine everything from network setups to access restrictions, software vulnerabilities, and employee training programs in order to reinforce the organisation’s digital fortress against external attacks and internal weaknesses.

What are the three main phases of a cybersecurity audit?

A cybersecurity audit typically consists of three main phases:

Planning: The planning step lays the groundwork for an effective cybersecurity audit. It entails defining the audit’s objectives and scope, collecting necessary documents, and conducting a risk assessment to detect potential vulnerabilities. Resources, such as manpower and tools, are allocated to ensure a complete and effective audit.

Execution: During the execution phase, auditors thoroughly examine the organisation’s information systems and security measures. This includes gathering information from system logs, analysing security configurations, and conducting access control assessments. Tests such as penetration testing and vulnerability scanning are performed, and the results are meticulously documented. Interviews and observations provide further information about the practical implementation of security policies.

Reporting: The reporting step includes gathering and presenting the audit findings to stakeholders. A complete report summarises vulnerabilities, dangers, and non-compliance, as well as actionable mitigation recommendations. The findings are communicated to management and the IT/security teams, ensuring that they understand the risks and essential measures. Follow-up activities may be planned to ensure that suggestions are implemented and that compliance continues.

How often should you conduct a cybersecurity audit?

The frequency of a cybersecurity audit is determined by a variety of factors, including the organisation’s size and composition, regulatory obligations, and the dynamic threat landscape. In general, a full cybersecurity audit should be conducted at least once a year.

However, for organisations in high-risk industries or those that handle sensitive information, more frequent audits—such as semi-annually or quarterly—may be required.

Audits should also be undertaken anytime substantial changes occur in the IT infrastructure, such as following an information security incident or the implementation of new regulatory requirements, to ensure continued alignment with best practices and compliance standards.

Types of Security Audits

Security audits are typically divided into two types: internal and external audits. Each type has distinct advantages and applications, and recognising the differences between them can assist businesses in selecting the best method for their requirements.

Internal Audits

Internal audits are performed by the organisation’s internal audit team or dedicated security personnel to determine the effectiveness of internal controls, policies, and procedures. They are essential to ensure that the organisation follows its defined standards and practices. By carefully reviewing these internal systems, internal audits assist in identifying gaps and areas for development, promoting a continual cycle of evaluation and refinement that increases the overall security posture.


  • In-depth Knowledge: Internal auditors have extensive knowledge of the organisation’s operations and culture, allowing them to provide deep insights into specific procedures and areas of focus.
  • Continuous Improvement: Regular security audits help maintain a continuous cycle of evaluation and improvement, ensuring that security measures evolve with emerging threats.
  • Cost-Effective: Conducting security audits may be more cost-effective than hiring external auditors, particularly for routine assessments.
  • Early Detection: Internal audits can help detect issues before they become significant problems, allowing for prompt remediation.

External audits

Independent third-party businesses or external auditors carry out external audits to give an objective and unbiased assessment of an organisation’s security posture. These audits are critical for ensuring alignment with regulatory or contractual requirements because they provide a new, objective viewpoint on the effectiveness of the organisation’s security controls. By employing the experience and objectivity of external auditors, organisations can gain valuable insights into their security strengths and weaknesses, boost their trust with stakeholders, and assure compliance with industry standards and regulatory responsibilities.


  • Unbiased Assessment: External auditors bring an impartial viewpoint, free from internal biases and conflicts of interest, providing a clear and objective assessment.
  • Enhanced Credibility: An external security audit can help to enhance credibility with stakeholders, including customers, partners, investors, and regulators, by demonstrating a commitment to high-security standards.
  • Compliance Assurance: External audits are often required to ensure compliance with laws, regulations, and industry standards, such as GDPR, HIPAA, and PCI DSS. This helps avoid legal penalties and maintain regulatory compliance.
  • Broad Expertise: External auditors often have a broad range of experience across different industries and sectors, providing valuable insights and best practices that can be applied to improve the organisation’s security posture.
  • Stakeholder Confidence: External audits reassure stakeholders that the organisation is diligently managing its security risks and protecting sensitive data, thereby building trust and confidence.

How Does a Security Audit Work?

A security audit is like a thorough check-up of your organisation’s digital infrastructure. Here’s a breakdown of how it typically works:

Setting the Criteria: The audit starts by determining the necessary criteria. This includes examining your organisation’s internal security policies and processes and ensuring compliance with external legislation such as Australia’s Privacy Act and international standards set by ISO and NIST.

Examining Your Practices: Auditors carefully examine your current IT processes to the set standards. This includes assessing current security policies, conducting interviews with key individuals to understand security awareness and practices better, and doing vulnerability assessments on your systems and networks to find flaws.

Reporting and Recommendations: After the assessment, a full report is created. This report documents the audit findings, identifies any weaknesses, and makes practical recommendations to remedy them. The recommendations are then prioritised according to their severity, assisting your organisation in improving its security posture.

Taking Action: Using the prioritised recommendations, an action plan is developed to remedy the vulnerabilities. These activities could include patching systems, changing security rules to reflect best practices better, or deploying wholly new security procedures to close detected gaps.

Scope of Cybersecurity Audit

The scope of a cybersecurity audit encompasses a broad range of elements within the organisation’s information systems and infrastructure. This may include;

Data Protection:  Assess data encryption practices, data backup procedures, and measures in place to prevent unauthorised access, alteration, or disclosure of sensitive data.

Network Security: Examine network configurations, firewalls, routers, and other network devices to identify vulnerabilities and ensure secure transmission of data.

Cloud Security: Assess security measures implemented for cloud-based services and infrastructure to ensure the protection of data stored or processed in the cloud.

Access Controls: Review access control mechanisms to ensure that only authorised individuals have access to sensitive information and resources.

Physical Security: Evaluate physical security measures, such as access controls, surveillance systems, and security personnel, to prevent unauthorised access to facilities and equipment.

Mobile Devices and BYOD Policies: Review policies and controls related to the use of mobile devices and Bring Your Own Device (BYOD) initiatives to address potential security risks.
