Data breaches have become an all-too-common occurrence. Every organization, regardless of its size or industry, is at risk of falling victim to a breach that can result in the theft of sensitive information or destruction of data. Thankfully, one way to mitigate such incidents is to perform data risk assessments.
In this article, you will learn about the importance of data risk assessment, the process involved, and how it can improve data protection.
As organizations continue to rely on technology to store and process data, the risk of cyber-attacks has become increasingly prevalent. From ransomware to phishing scams, cybercriminals have numerous methods to inappropriately accessing the data they covet.
The impact of a data breach can be far-reaching, with serious financial and reputational repercussions. Additionally, organizations that experience a breach may have legal or ethical obligations to comply with data protection law that can lead to additional costs for investigation into the personal data breach, estimate affected population, and letting people know about the breach.
To mitigate such risks and manage security threats, experts propose implementing a data risk management strategy, which includes conducting a risk assessment report. A data risk assessment enables organizations to identify vulnerabilities, prioritize and categorize potential risks, and examine the impact of the breach if it were to occur.
Process of Performing a Data Risk Assessment
The data risk assessment process can be broken down into five stages: inventory sensitive data, categorize the data, prioritize the assessment, audit security controls, and create a risk assessment report.
Inventory sensitive data: Organizations must identify where their sensitive data resides. It could be in virtual or physical locations, such as a server or a filing cabinet. These should be documented in an inventory list.
Categorize the data: It is crucial to understand the type of data contained within files and folders, and its informational value to determine the level of sensitivity with respect to confidentiality, availability, and integrity. Classify each data based on their level of sensitivity.
Prioritize the assessment: This involves evaluating the likelihood of occurrence of a data breach and the potential damages in the event that the data is compromised. The assessment identifies critical assets and protection measures that need to be prioritized.
Audit security controls: Organizations often employ a suite of security controls like firewalls, application security, security guards, and other security and privacy controls to manage their data protection. These measures should be audited thoroughly to reveal security and privacy control shortcomings.
Create a risk assessment report: The last step is documenting the identified vulnerabilities and threats and calculating the level of risk associated with them. This report lists recommendations for mitigating potential risks and improving a company’s overall data security posture.
By following all these steps, organizations can have a better understanding of their potential risks and the improvements necessary to secure their data.
Importance of Performing a Data Risk Assessment
By performing data risk assessments, organizations can take proactive steps towards minimizing the likelihood of data breaches and the impact of any breaches that occur. The following are some benefits of conducting regular data risk assessments:
Identify information security and privacy control weaknesses: Data risk assessments can help to identify areas where an organization’s security controls can be improved. This could be areas such as data storage, access control policies, incident response procedures, or data encryption practices.
Reduce risks of data breaches: By identifying potential risks, organizations can take steps to prevent or minimize these risks. This could include implementing stronger security controls, improving access control measures, or increasing staff training and awareness.
Comply with regulatory standards: Data risk assessments help organizations identify where their sensitive data resides, which files and folders contain critical information, and prioritize assets before identifying vulnerabilities, threats, calculating risks, and documenting findings. This document can be used to support the organizations’ compliance with regulatory standards like HIPAA, PCI-DSS, and FISMA.
Mitigating Risks and Containing the Breach
In the event that a breach occurs, it is critical to contain the breach and mitigate its impact. Actions taken post-breach are crucial.
Contain the breach: The first step is to contain the breach to prevent further damage. This could involve disconnecting infected systems from any network, disabling affected accounts, or suspending any affected services or applications.
Investigate the breach: An investigation should be launched to determine the type of personal data involved, the impact of the breach, the vulnerability that led to the breach, and the duration of the breach. This information will inform any necessary reporting and the subsequent mitigation measures.
Estimate the affected population: Estimate the number of affected individuals, the type of personal data involved, and the potential risks or threats they could face. This can guide effective communication of the breach to affected parties, including regulatory authorities and law enforcement agencies.
Letting people know about the breach: Affected individuals must be informed of the breach and the potential risks or threats they may face. This should follow data protection law, which in most cases requires notification within 72 hours after a personal data breach.
Mitigating the impact: Finally, organizations should take practical steps towards mitigating the impact of the breach, such as offering credit monitoring and identity theft protection, implementing stronger security controls, improving access control measures, or increasing staff training and awareness.
Conclusion
Regular data risk assessments form an integral part of a robust data protection and risk management strategy. By performing a data risk assessment, an organization can take a proactive approach to mitigate the impact of data breaches and protect customer information. Organizations that prioritize data privacy and security by regularly assessing associated risks, identifying vulnerabilities, and taking practical steps towards mitigating them are better positioned to avert data breaches and reputational damage that could lead to legal or regulatory consequences.
