How should my business conduct a cyber risk assessment?

A proper cyber risk assessment is the foundation of effective cyber security and regulatory compliance. It helps you understand what you need to protect, what threats you face, and where your defences are weakest.

1. Why Conduct a Risk Assessment?

• Regulatory compliance: The Privacy Act, SOCI Act, and standards like APRA CPS 234 require organisations to maintain security “commensurate with” their risks.
• Insurance requirements: Cyber insurers increasingly require documented risk assessments and security controls as conditions of coverage.
• Director duties: Directors have a duty to exercise reasonable care. Failing to understand and manage cyber risk may expose directors to liability.
• Resource allocation: A risk assessment helps you prioritise security spending on the areas that matter most.

2. Key Components of a Cyber Risk Assessment

a) Asset Identification

What are your critical assets? This includes:

• Customer databases and personal information.
• Financial systems and payment processing.
• Intellectual property (source code, designs, trade secrets).
• Operational technology systems.

b) Data Mapping

Under the Privacy Act, you must know:

• What personal information you collect.
• Where it is stored (including third-party systems).
• Who has access to it.
• How long you retain it.

c) Threat Analysis

What threats are most likely to affect your business?

• Ransomware and malware.
• Business email compromise.
• Insider threats (disgruntled employees, accidental disclosure).
• Supply chain attacks via third-party vendors.

d) Vulnerability Assessment

Where are your weaknesses?

• Outdated software and unpatched systems.
• Weak password policies.
• Lack of multi-factor authentication.
• Insufficient staff training.
• Inadequate backup and recovery procedures.

e) Impact Analysis

What would be the consequence of a breach?

• Financial loss (ransom, fraud, business interruption).
• Regulatory penalties.
• Reputational damage.
• Legal claims from affected parties.

3. Third-Party Vendor Risk

Your security is only as strong as your weakest vendor. Assessment should include:

• Security questionnaires for key suppliers.
• Contractual requirements for data protection.
• Right to audit clauses.
• Incident notification requirements.

4. Documentation and Governance

Document your assessment, including:

• Risk register with identified risks, likelihood, and impact.
• Treatment plan (accept, mitigate, transfer, or avoid).
• Assigned responsibilities for each risk.
• Review schedule (at least annually).

5. Legal Review

A lawyer experienced in cyber risk can:

• Ensure your data mapping meets Privacy Act requirements.
• Review policies for regulatory compliance.
• Advise on insurance adequacy.
• Help draft vendor contracts with appropriate security clauses.
