What is a Data Breach?

A data breach is set out in article 4(12) of the GDPR as : “a breach of security leading to the accidental or unlawful destruction, loss, alteration, unauthorised disclosure of, or access to, personal data transmitted, stored or otherwise processed”

Therefore while a data breach can occur in serious events like identify theft, or be caused by cyber attacks, most data breaches are more low level. They can happen within organisations, and they do not rely on malicious actions or intent.

Understanding the Significance of Personal Data Breaches

Data breaches can lead to identity theft, financial loss, reputational damage, and emotional distress for affected individuals. Any incident involving personal data can be difficult to recover from. A breach of personal information can reduce trust in organisations and this can have a devastating effect if people lose faith in healthcare, criminal justice, or other public sector services.

Organisation’s that do not try to prevent data breaches, and if they occur, tackle them effectively is likely to be subject to some form of regulatory action. These can include financial penalties or even criminal prosecution.

In addition organisations should not underestimate the reputational impact of a serious data breach

Preventing Data breaches

If a data breach does occur you can limit the extent of it, and the impact on your organisation, by showing you took every reasonable step to avoid the breach occurring.

Examples of how to avoid a data breach include:

• training staff in data protection and information security

• appointing a data protection officer (DPO)

• identifying high risk personal data and data processing, and taking steps to enhance the security of them

• having systems to detect unauthorised access like cyber attacks

• undertaking a regular data security audit

The GDPR envisages a data protection regime called “data protection by default and by design”. This means organisation are expected to design their systems with information security in mind, to prevent data breaches wherever possible.

Establishing a Data Breach Response Plan

Even before any data breach occurs you should have an incident response plan. Ideally this would be linked to your business continuity plan. Remember, a data breach can result in reputational damage. Your plan should include communication with stakeholders such as customers. The importance of having a data breach response plan is clear: a well-prepared plan helps organisations respond swiftly and effectively in the event of a breach.

The are a number of steps your plan should consider in order to be complete.

1. Decide how your plan will be activated. What would trigger it? Not every breach is so serious that the full plan will be needed. For example, some breaches like inappropriately sharing account passwords can be handled in line with your data protection policy.

2. Designate the data protection officer or a senior manager as the plan’s owner. This person will be responsible for owning the plan, keeping it up to date, and managing the breach response process.

3. Define roles and responsibilities. The plan should outline the roles of key stakeholders who will form your incident response team, such as the IT, legal, and communications teams.

4. Develop a communication strategy: plan how and when to inform affected individuals, regulatory authorities, and other relevant stakeholders about the breach.

5. Determine your recovery plan – how will you restore your systems, re-establish security, get back to business as usual and put the incident behind you?

6. Document the response plan: ensure the response plan is well-documented and easily accessible to all relevant personnel.

7. Decide what you will do if you identify the source of any attack – cyber attacks may also be a matter for law enforcement for example.

Detecting and Assessing a Data Breach

It is important that you identify data breaches quickly and take action without undue delay. One reason is that the sooner you act, the less damage that any data breach may cause. The second is that if a data breach is notifiable (see below) you must make the notification within 72 hours of becoming aware of it.

Clearly if there is a lengthy period between a breach occurring and your notification of it, questions could be asked about your systems.

Firstly you must establish a system for detecting breaches. They can include a mechanism for people reporting something that doesn’t seem right. They can also include automated systems to detect cyber attacks, log devices on your network or record access to electronic files. Whatever your data systems may be, you need to monitory physical and electronic security constantly and encourage people to speak up. You should also consider if any complaints about your data handling suggest a data breach might have occurred. They key action is to implement robust monitoring and detection mechanisms to identify breaches promptly.

When a breach occurs you must assess the scope, nature, and severity of the breach to determine the potential risks and affected individuals. Conducting a risk assessment will help you evaluate the potential consequences of the breach on individuals’ rights and freedoms to determine the appropriate response. This will include whether or not the breach is notifiable to the information commissioner and people affected.

Finally, document the breach assessment. Maintain thorough documentation of the breach, including the date, time, nature, and initial findings.

Key Questions

Some of the key questions you will need to answer if a data breach occurs are:

• what information has been compromised? It is more serious if it sensitive data like health information, or could lead to harm like identity theft.

• how many people have been affected? The more people affected the greater the risks.

• who has been affected? Remember you have data about a broad range of people – employees, clients, suppliers etc.

• are the people affected vulnerable in some way? Examples of vulnerabilities that can make a data breach worse include children, people at risk of discrimination, or people with health problems that reduce their capacity to act.

• what harm could occur from the data breach? Remember, harm could include emotional distress as well as material losses.

• is there any additional information that is needed to understand the breach, and inform your incident response?

How to Handle a Data Breach

Once a data breach occur the next step will be to activate your Data Breach Response Plan, and work to answer the questions listed above.

The most important things to do are:

• stop the data breach from continuing. That means cutting off access to the data from the people who have caused the breach. Remember, breaches can be accidental as well as deliberate.

• mitigate immediate risks. If, for example, a data breach has limited your access to important operational data like customer information then you need to think about how you will handle this and get things back to normal.

• decide if the breach is serious enough to require notification to the Information Commissioner, and if so whether the people whose data have been compromised need to be notified as well.

• engage external experts if necessary. Sometimes you may need external expert advice and support, such as forensic specialists or legal counsel, to ensure a thorough investigation and appropriate response.

It is of course important to restore the security and integrity of the data and information that you hold. If you are able to swiftly tackle a breach then you can reduce the risk of reputational damage, financial losses, and regulatory action against you.

Notification of a Personal Data Breach

There are two types of notification you may have to make if a breach occurs.

The first is notification to the Information Commissioner’s Office (ICO), or relevant data protection authority if the breach happens outside the UK.

The second type is to inform affected individuals. Article 34 of the GDPR sets out that: when the personal data breach is likely to result in a high risk to the rights and freedoms of natural persons, the controller shall communicate the personal data breach to the data subject without undue delay.

If you do need to notify individuals whose personal data has been compromised you should:

• provide clear and concise information about the breach and its potential impact.

• offer support and guidance – give people resources and information on steps they can take to protect themselves against potential harm. It might be helpful to give people an email or phone number to use if they have any concerns or queries, or need help to understand the facts.

• give people tools to help them avoid harm, such as free access to their credit report or credit monitoring, contact information of organisations that can provide support, or new accounts to access your products or services online.

Naturally, you will want to say sorry for the breach and explain what you are doing to ensure it is being addressed.

Learning from the Breach

The final part of addressing a data breach is the learning. Obviously if the same kind of breach occurs again and again there is something fundamentally wrong with your systems. If you conduct a post-breach analysis you can evaluate the causes and consequences of the breach to identify areas for improvement. Then you will know how to handle a data breach better next time.

If you have identified vulnerabilities implement remedial measures and strengthen security measures to prevent future breaches.

You may need to update policies and procedures or employee training programmes to incorporate lessons learned from the breach. You may also need to review your contracts with service providers to address any gaps.

How could your incident response plan be improved? What worked well when your plan was activated and what didn’t?

Finally you should continuously monitor and review data protection practices to ensure ongoing compliance and readiness to prevent and improve how you handle future breaches.

Conclusion: Key Takeaways on How to Handle a Data Breach

Knowing how to handle a data breach effectively requires a proactive and well-structured approach. By understanding the significance of breaches, establishing a response plan, promptly detecting and assessing breaches, responding effectively, and learning from the experience, organisations can minimise the impact of breaches on individuals’ privacy rights and meet their legal obligations. They can also avoid regulatory action and protect their brand from any reputational damage a breach might cause.
