The world has changed significantly since the development of the first computers. Since then, businesses have become increasingly reliant on their IT systems, networks, and infrastructure – from managing day-to-day operations to storing sensitive information.
However, as the reliance on technology grows, so do the risks. Cybersecurity threats pose a significant risk for businesses of all sizes. If not caught early or resolved, these threats can result in significant losses.
Cybersecurity audits are your first line of defence against these risks. Regular IT checks are essential in identifying system vulnerabilities before they can be exploited, ensuring your business’s sensitive information is well-protected and your operations stay secure.
Want to learn about how a cybersecurity audit can boost your business’s defence against digital threats? As cybersecurity experts, we outline everything you need to know about cybersecurity audits, from what they are, the benefits they have and key steps to follow when conducting an audit.
A cyber security audit is a comprehensive analysis and review of your business’s IT infrastructure. It is a process designed to detect vulnerabilities and potential threats that could expose your systems to cyberattacks. By reviewing your hardware, software, networks, and data management procedures, the audit identifies weak links, high-risk practices, and potential entry points for criminals and attackers.
While these services initially focused on basic upkeep, they have evolved to include a range of comprehensive solutions and services, such as planning, advanced threat protection, and cloud computing integration (essential for business growth and scalability).
Many Australian businesses face a variety of cybersecurity threats. In fact, a 2022-23 study revealed that the average cost of cybercrime for small businesses rose to $46,000, and for medium businesses, it climbed to $97,000. This is often caused by:
Most often, the scope of security audits varies based on your business size and complexity. Small businesses will generally focus on simple security measures, including multi-factor authentication, software updates, and regular data backups. Larger organisations require more comprehensive audits that address advanced topics like network security monitoring, system security patching, privileged account management, and physical security assessments.
Cybersecurity audits are an essential part of maintaining a secure IT environment. Your business should run cyber security audits at least once a year. However, while an annual audit is a good baseline, you might need to conduct more frequent audits depending on several factors. For example, major operational changes, such as new systems or expanding infrastructure, call for extra audits to ensure that these updates don’t introduce new vulnerabilities. Similarly, if your business handles sensitive data or operates in regulated industries like healthcare, finance, or e-commerce, it’s important to conduct more frequent audits throughout the year.
Regular cybersecurity audits offer a range of critical benefits, not only for your business but your customers as well.
Smart security starts with careful planning. A well-structured cyber security audit begins with preparation and involves a series of steps to ensure a full and comprehensive review of your IT systems and infrastructure.
The first step in planning your cybersecurity audit is to define its specific goals and objectives. What is the purpose of the audit? Are you evaluating network security, assessing data protection practices, or reviewing compliance with regulations?
Establishing clear goals helps you focus your efforts on the most important areas of your IT infrastructure and ensures the audit is thorough and aligned with your business priorities.
Using the right tools is key to conducting a successful audit. Depending on your audit goals, you may need tools for virus scanning, network monitoring, vulnerability detection, and more. The right tools will provide you with the insights needed to identify risks and weaknesses within your systems.
When conducting an audit, you need to know where to start or what to look for. Conducting a vulnerability and risk assessment helps you identify potential threats, weaknesses, and high-risk areas within your IT systems. This involves evaluating the sensitivity and value of your data, the likelihood of different types of cyberattacks, and the impact a breach could have on your business operations. By understanding these risks, you can prioritise the most critical areas for audit focus and allocate resources effectively.
Compliance checks assess whether your systems meet the standards required for your industry. During this phase, track any gaps between your current practices and the necessary standards. Identifying compliance shortfalls ensures that you’re not only protecting your business from cyberattacks but also from legal and regulatory consequences.
Technical assessments, such as penetration testing, simulate real-life cyberattacks to test the resilience of your systems. Penetration testing involves attempting to breach your applications, servers, and APIs to identify weak points that attackers could exploit and use to gain access.
Other techniques, like virus scanning, will help uncover malware or suspicious files that could put your business at risk. These tests provide valuable insights into your technical defences and how they stand up against potential attacks.
Security incident logs are an invaluable resource when it comes to understanding the health of your cybersecurity defences. These logs are generated by systems such as intrusion detection systems (IDS), firewalls, and antivirus software and detail insights into suspicious activities, unauthorised access attempts, or potential policy violations within your network. By reviewing these logs, you can identify patterns of unusual behaviour, ongoing attacks, or vulnerabilities that have already been exploited.
Once the audit is complete, it’s time to document the findings. Record all identified vulnerabilities, weaknesses, and areas in need of improvement. This will offer clear steps for addressing each issue, and prioritise them based on the level of risk and potential impact on your business. This evaluation should include both technical fixes (e.g. patching vulnerabilities) and procedural improvements (e.g. employee training or policy updates).
Following the audit, it’s essential to act on the findings and recommendations as soon as possible. This involves fixing vulnerabilities, strengthening your security measures, and implementing any necessary changes. Once these fixes are complete, it is essential to continue to monitor your systems to ensure that improvements are effective. Reaudits may also be needed periodically to track progress and verify that no new issues have emerged.
Security audits can be conducted by both a business’s in-house IT team or outsourced to a third-party provider. Both have the same goal, but offer unique advantages. Choosing the right type – or a combination of both – can make a significant difference in how effectively you protect your business.
Internal audits are conducted by your organisation’s own security team. With direct access to systems, processes, and employees, internal reviews can be performed quickly and frequently. They are often more cost-effective and tailored to your specific needs.
However, internal audits may have limitations. Small and medium-sized enterprises (SMEs), in particular, might lack the time, expertise, or resources to conduct comprehensive reviews which leave gaps in your security framework, increasing the risk of undetected vulnerabilities.
External audits are conducted by independent experts, like the team at CRT Network Solutions. With advanced skills, specialised tools, and a deep understanding of cybersecurity trends, these professionals bring an unbiased and objective perspective to the business’s systems. They know exactly what to look for and where to find vulnerabilities, covering areas that internal teams might overlook.
If you opt for an external cybersecurity audit, choosing the right provider is essential to ensure a thorough and effective evaluation. Here are some key factors to consider:
Security audits protect what matters most – your business. Regular and comprehensive security audits ensure that sensitive data stays secure, mitigate risks, and help prevent costly cyberattacks. Whether they are conducted internally or outsourced to third-party experts, security audits ultimately ensure you can make informed decisions about your IT systems.
