IT Risk Register: How to Build One for Your BusinessReading Time: 12 minutes

IT <a href=

Australian IT businesses are under more pressure than ever to manage their technology risks properly. Cyber attacks are increasing in both frequency and sophistication, data breaches are hitting the headlines with alarming regularity, and regulators are watching closely. In 2024 alone, Australian organisations reported 1,113 notifiable data breaches to the Office of the Australian Information Commissioner — the highest annual total since mandatory reporting began, and a 25% increase on the year before. At the same time, the Privacy Act has been significantly strengthened, with maximum penalties for serious breaches now reaching $50 million or 30% of adjusted turnover.

Against that backdrop, having a clear, current IT risk register is no longer a nice-to-have. It’s one of the most practical tools a business can maintain to understand its exposure, demonstrate due diligence, and take action before something goes wrong. This guide explains what an IT risk register is, what it should include, and how to build one that actually works for your business.


What Is an IT Risk Register?

An IT risk register is a structured document — or, better still, a live system — that records all of the technology-related risks your organisation has identified, along with information about their likelihood, potential impact, existing controls, and who is responsible for managing them.

Think of it as a central record of everything that could go wrong with your information systems, data, or technology infrastructure, and what you’re doing about it. An IT risk register brings together risks from across the organisation — from server vulnerabilities and software misconfigurations to third-party supplier access and employee behaviour — and gives leadership a clear, consolidated view of the threat landscape.

The IT risk register is closely related to, but distinct from, a broader enterprise risk register. Where an enterprise risk register captures all categories of organisational risk (financial, operational, reputational, legal), the IT risk register drills into the technology layer specifically. It sits within the broader discipline of information security risk management, which concerns itself with protecting the confidentiality, integrity, and availability of information.

In practice, the register is a living document. It should be reviewed and updated regularly — at minimum quarterly, and immediately following any significant change to your IT environment or after an incident. The risks you face today may be very different from those you face in twelve months, especially in a threat environment that evolves as quickly as cyber security does.

A well-maintained IT risk register also supports compliance. Regulators, auditors, and cyber insurers increasingly want to see evidence that your organisation has a structured, documented approach to identifying and managing technology risk. The register is often the first document they ask for.


Why IT Risk Management Is Critical for Australian Businesses

The regulatory environment for Australian businesses has shifted considerably in recent years, and the direction of travel is clear: stronger obligations, higher penalties, and less tolerance for organisations that cannot demonstrate active risk management.

The Notifiable Data Breaches scheme requires any Australian organisation with an annual turnover above $3 million — plus certain other categories of organisations regardless of turnover — to notify both affected individuals and the Office of the Australian Information Commissioner (OAIC) when a data breach is likely to result in serious harm. Malicious or criminal attacks accounted for 69% of all notifications in the second half of 2024, a 17% rise on the previous reporting period. Healthcare, finance, and legal services are among the most frequently affected sectors.

The Privacy Act amendments that came into force in 2024 and 2025 significantly strengthened the regulatory framework. The Privacy and Other Legislation Amendment Act 2024 introduced expanded OAIC enforcement powers, a statutory tort for serious invasions of privacy, and criminal penalties for certain offences. Maximum civil penalties for serious or repeated privacy breaches now sit at the greater of $50 million, three times the benefit obtained from the breach, or 30% of adjusted turnover. These are not theoretical figures — they are designed to be commercially meaningful.

The Cyber Security Act 2024 introduced mandatory ransomware payment reporting. Businesses that make a ransomware or cyber extortion payment must now report it to the Australian Signals Directorate within 72 hours.

The financial cost of incidents is also significant. For the healthcare sector, the average cost of a data breach in Australia reached AUD $10.93 million in 2024. Even for smaller organisations, a single incident can result in legal costs, regulatory investigations, customer remediation, reputational damage, and lost business.

A properly maintained IT risk register does not prevent cyber threats from existing. But it gives your organisation the visibility to prioritise resources, implement controls, and demonstrate to regulators that you are managing your obligations seriously.


What Should an IT Risk Register Include?

The specific structure of an IT risk register will vary depending on your organisation’s size and sector, but a robust register will typically capture the following fields for each identified risk.

Risk category. Group risks into logical categories — for example, data security, network infrastructure, end-user devices, third-party and supplier risk, cloud services, physical access, and business continuity. Categories make it easier to identify patterns and gaps across the register.

Asset affected. Identify the specific system, application, data set, or service that is at risk. This might be your customer database, your ERP platform, a cloud storage environment, or your email system. Being specific here is important — it connects the risk to real operational context and makes remediation more actionable.

Threat. Describe the threat itself: what could actually happen? Common examples include ransomware infection, unauthorised access by an external attacker, accidental deletion of data by an employee, or a supplier suffering a breach that exposes your data.

Vulnerability. Identify the weakness that the threat could exploit. This might be an unpatched operating system, weak password practices, excessive user access privileges, or a lack of multi-factor authentication on a critical system.

Likelihood rating. Assign a rating — typically on a 1–5 or 1–3 scale — reflecting how likely the risk is to materialise given your current controls. Your likelihood assessment should be based on your actual environment, not generic industry benchmarks.

Impact rating. Assess the potential consequence if the risk were to materialise. Consider financial loss, regulatory exposure, operational disruption, and reputational damage. Like likelihood, this should be rated on a consistent scale.

Risk score. Most registers calculate a risk score by combining likelihood and impact, often using a risk matrix. This gives you a prioritised view of which risks deserve immediate attention.

Existing controls. Document what controls are already in place — for example, endpoint detection software, firewall rules, access management policies, or backup procedures. This tells you what is already working, and where gaps remain.

Treatment plan. For risks above your accepted threshold, record the action being taken: is the risk being mitigated, transferred (for example, through cyber insurance), tolerated, or avoided? Include the specific actions, responsible owner, and target completion date.

Risk owner. Every risk needs a named owner — a person who is accountable for monitoring the risk and driving remediation. Without ownership, risks sit in registers and nothing happens.

Review date. Record when the risk was last reviewed and when it is next due. Stale risk data is as dangerous as no data at all.


Common IT Risks for Australian Businesses

Understanding the threat landscape helps you build a more complete and accurate register. These are the IT risks most commonly affecting Australian organisations.

Data breaches. Unauthorised access to personal or sensitive business data remains the most reported category of IT incident in Australia. Breaches can result from external attacks, misconfigured systems, or employee error. Given the NDB scheme obligations, this category of risk needs to be front and centre in any IT risk register.

Ransomware and malware. Ransomware continues to be a primary threat to Australian organisations across all sectors. Attackers encrypt systems or data and demand payment for their release. The business disruption, recovery costs, and reputational fallout can be severe — and, under the Cyber Security Act 2024, ransomware payments must now be reported to government.

Phishing and social engineering. Email-based phishing attacks are the most common entry point for cyber attackers. Employees clicking malicious links or providing credentials to fake websites remain a persistent vulnerability. Business email compromise (BEC) — where attackers impersonate executives or suppliers to redirect payments — is a particular concern for finance teams.

Third-party and supplier risk. Many data breaches occur not through direct attack but through a supplier or service provider. If your vendors have access to your systems or data, their security posture becomes your risk. Third-party access controls and supplier due diligence are critical components of any IT risk register.

Insider threats. Current or former employees, contractors, or partners with access to systems can cause significant harm — whether through malicious intent or simple carelessness. Overly broad access privileges are a common vulnerability that internal risk registers often overlook.

Cloud misconfigurations. As Australian businesses increasingly move workloads to cloud platforms like AWS, Azure, and Google Cloud, misconfigured storage buckets, exposed APIs, and inadequate identity management have become significant sources of risk. Cloud security requires ongoing attention, not a set-and-forget approach.

Unpatched systems and software. Attackers actively exploit known vulnerabilities in software and operating systems. The Australian Signals Directorate’s Essential Eight framework identifies patching applications and operating systems as two of its eight foundational strategies — highlighting just how significant this risk is in practice.


How to Build an IT Risk Register Step by Step

Building an IT risk register does not have to be an overwhelming project. Taking a structured approach will help you create something genuinely useful rather than a document that gathers dust.

Step 1: Define your scope and objectives. Before you start listing risks, be clear about what your register needs to cover. Will it encompass all IT systems across the business, or a specific division or system? Who is the audience — your leadership team, your board, your auditors? Clarity on scope prevents the register from becoming either too narrow to be useful or too broad to be manageable.

Step 2: Identify your information assets. Map out the systems, data sets, applications, and infrastructure that your organisation relies on. This asset inventory forms the foundation of risk identification — you can only assess risk to things you know about.

Step 3: Identify risks for each asset. For each asset, work through the potential threats and vulnerabilities. Involve your IT team, operations managers, and business unit leaders — people who work with these systems every day often have the best insight into where the real exposures lie.

Step 4: Assess likelihood and impact. Rate each identified risk using a consistent scoring approach. Agree your rating scale upfront and apply it consistently across the register. A risk matrix — with likelihood on one axis and impact on the other — is a straightforward tool for this step.

Step 5: Document existing controls. For each risk, record what controls are already in place. This is where you will quickly see which risks are well-managed and which are inadequately controlled.

Step 6: Develop treatment plans for high-priority risks. Any risk that sits above your agreed risk appetite threshold needs a treatment plan with a named owner and a target date. Risks without owners and deadlines rarely get addressed.

Step 7: Review and maintain the register. Set a review cadence — at minimum quarterly — and build in trigger events that prompt an unscheduled review, such as a new system being deployed, a significant software change, a cyber incident, or a change in the regulatory environment.


IT Risk Register vs Cyber Security Framework

An IT risk register and a cyber security framework are different things, but they are most effective when used together.

A cyber security framework provides a structured set of practices, controls, and benchmarks that organisations can adopt to improve their security posture. For Australian businesses, the two most relevant frameworks are:

The Essential Eight, developed by the Australian Signals Directorate (ASD). It outlines eight mitigation strategies considered the most effective baseline controls against the most common cyber threats: patching applications, patching operating systems, multi-factor authentication, restricting administrative privileges, application control, macro settings, user application hardening, and regular backups. Each strategy is assessed against maturity levels 1 through 3. While mandatory only for Australian government entities, the Essential Eight is increasingly expected by enterprise clients, cyber insurers, and government contractors across the private sector.

ISO 27001:2022, the international standard for information security management systems (ISMS). ISO 27001 provides a comprehensive management framework for systematically identifying, assessing, and treating information security risks. Clause 6.1.2 of the standard specifically requires organisations to establish an information security risk assessment process and maintain a risk register. Achieving ISO 27001 certification signals to customers, partners, and regulators that your organisation manages information security to an internationally recognised standard.

The distinction is important: a framework tells you what good looks like, while your IT risk register records where you currently are and what you are doing to get there. Your risk register should reference the controls in your chosen framework and track your progress toward implementing them. For example, if you are working toward Essential Eight Maturity Level 2, your register might include risks associated with gaps in your current patching or MFA implementation, with treatment actions aligned to closing those gaps.

The two tools are complementary, not interchangeable. Using both together gives you the structure of a framework and the operational specificity of a risk register.

Frequently Asked Questions

What is an IT risk register?

An IT risk register is a structured record of all technology-related risks that an organisation has identified. For each risk, it captures information about what could go wrong, how likely it is, what the potential impact would be, what controls are in place, who is responsible, and what action is being taken. It is a central tool for managing cyber security and information security risk in a systematic, documented way.

What IT risks should Australian businesses include in their risk register?

The most common and significant IT risks for Australian businesses include data breaches, ransomware attacks, phishing and business email compromise, third-party and supplier access risks, insider threats, cloud misconfigurations, and unpatched systems or software. Your register should reflect the specific systems, data, and threat context of your organisation — not just a generic list.

Is an IT risk register required by Australian law?

There is no single law that explicitly requires an IT risk register by name. However, a range of regulatory obligations effectively require the systematic approach to risk management that a register supports. The Privacy Act 1988 and the Notifiable Data Breaches scheme require organisations to have appropriate data security measures in place. APRA-regulated entities must comply with CPS 234, which includes information security risk management requirements. ISO 27001 certification — increasingly required or preferred by government and enterprise clients — mandates a formal risk register. Regardless of specific obligations, regulators and insurers expect documented evidence of risk management.

How is an IT risk register different from a cyber security framework?

A cyber security framework — such as the Essential Eight or ISO 27001 — defines what good security practice looks like and what controls organisations should have in place. An IT risk register records your organisation’s specific risks, your current controls, and your plan to close gaps. The framework provides the standard; the risk register tracks your actual position relative to that standard. Both are most effective when used together.

How often should an IT risk register be reviewed?

At a minimum, your IT risk register should be reviewed quarterly. It should also be reviewed promptly following any significant change to your IT environment, after a cyber incident or near-miss, when a new material supplier is engaged, or when there is a change in the regulatory or threat landscape. Risk data that is more than twelve months old without review is unlikely to accurately reflect your current exposure.
