A practical guide for small businesses, sole traders, and SMEs to navigate the risk assessment process following a personal data breach.
When a personal data breach occurs, the immediate response often focuses on containment. However, understanding and assessing the risks posed by the breach is a critical step that determines the necessary follow-up actions. Whether it’s a misdirected email, a stolen laptop, or lost records, conducting a thorough risk assessment will help mitigate potential harm and protect those affected.
Step 1: Verify if Personal Information is Involved
Before proceeding with a risk assessment, confirm whether personal information is part of the breach. Personal data encompasses any information that can identify an individual, such as names, addresses, photographs, or financial records. If the breach involves business information only (e.g., limited company email addresses), it may not qualify as a personal data breach under legal definitions.
Practical Example
Imagine an email about your business is sent to multiple recipients with email addresses visible to all. If these are private customer emails, this constitutes a personal data breach. However, if the email addresses belong to limited companies, it’s unlikely to be considered personal information. For more on what constitutes personal data, refer to the ICO’s Guide to Data Protection.
Step 2: Identify the Breached Information
Investigate the specific details of the breached data. Start by understanding what personal information has been compromised. If your organisation doesn’t already have a data inventory, create one promptly. Knowing what type of information is involved helps determine the severity of the situation.
High-Risk Data
Sensitive information, such as health records or financial data, typically poses a higher risk and requires heightened caution. Vulnerable groups, like children or individuals with additional safeguarding needs, also demand particular attention when their information is affected. Learn more about high-risk data in the ICO’s Risk Management Guidance.
Step 3: Determine Who Has Access
Next, consider who might have access to the breached data. This influences the level of risk significantly:
Internal mishandling: Sending personal data to the wrong department within your organisation poses a lower risk compared to an external exposure.
External parties: Data accessed by unauthorised individuals or stolen outright presents a more serious scenario. Investigate the breach thoroughly to understand the extent of exposure. For tips on handling data breaches, visit the NCSC’s Cyber Security Guidance.
Step 4: Quantify the Number of Affected Individuals
Assess how many people are impacted by the breach. A single misdirected email is easier to manage than an incident involving thousands of customer records. As you gather more details, your initial risk assessment may evolve.
Investigative Actions
For example, if documents were sent to the wrong address, confirm their contents to determine how many people are affected and the level of risk involved. This may require additional investigation to clarify the full impact of the breach. For guidance, use the ICO’s Personal Data Breach Checklist.
Step 5: Evaluate the Impact on Individuals
Consider how the breach could affect those involved. Key questions include:
Are the individuals children or vulnerable adults?
Could the breach lead to financial loss, job insecurity, or housing issues?
Might the breach cause emotional distress or reputational damage?
Example Scenarios
A breach involving financial details might heighten the risk of identity theft or fraud, whereas a minor incident involving appointment reminders might have negligible consequences. Tailor your response to the potential severity of harm. For more examples, review the ICO’s Data Breach Case Studies.
Step 6: Document the Breach and Its Causes
Investigate the root cause of the breach and document your findings. Common causes include:
Human error, such as misdirected emails or lost files.
Technical failures, like system breaches or unencrypted data storage.
Malicious actions, including hacking or deliberate misuse of data.
Mitigating Steps
Contain the breach where possible by:
Retrieving or securely deleting compromised information.
Requesting third parties to remove any mistakenly shared data.
Strengthening security measures, such as updating passwords or implementing multi-factor authentication.
For containment strategies, explore the NCSC’s Incident Management Guidelines.
Step 7: Conduct a Risk Assessment
Even if you don’t have all the details immediately, begin assessing the risk based on available information. Focus on the potential harm to individuals rather than the organisation’s reputation or financial loss. Consider:
Likelihood: What is the probability of harm occurring?
Severity: How significant would the impact be if harm occurs?
A breach that poses minimal risk to individuals can be categorised as low risk, but high-risk breaches demand urgent attention and comprehensive mitigation efforts.
High-Risk Indicators
If the breach involves sensitive data or could significantly harm affected individuals, prioritise notifying them promptly and take additional steps to protect their information. Use the ICO’s Reporting Tool to report high-risk breaches.
Final Thoughts
Conducting a detailed risk assessment is an essential component of responding to a personal data breach. While not every breach requires formal reporting, assessing the potential harm ensures you’re prepared to address the situation responsibly and minimise its impact.
Remember, the ICO offers resources and guidance to help organisations manage breaches effectively. By staying proactive and transparent, you’ll safeguard your business’s reputation while protecting the individuals affected by the breach. Explore the ICO’s Resource Hub for further assistance.
