9 Tips for Creating a Data Classification Policy

Data classification can be described as the process of organizing and labeling data based on key factors such as sensitivity, value, and risk. The need for classifying data has become crucial in today’s increasingly data-driven business environment. Having an effective data classification policy is important because of the number of benefits it provides.


What is a Data Classification Policy?

A data classification policy is a clear definition of standards or guidelines that stipulate how data should be categorized and protected in an organization. Data classification standards provide a holistic framework for classifying or organizing data according to criteria such as sensitivity, importance, and potential risks. An effective data classification policy must have clear instructions on how to access, handle, label, process, store, transmit, and dispose of various kinds of data.


Benefits of Having a Data Classification Policy

All organizations come across data/information with varying levels of risk, value, and importance. A data classification policy helps organizations develop adequate data management procedures, including security and protection measures.

Here are some key benefits of a data classification policy:


Effective Compliance

Several formal regulations emphasize the need to protect a particular kind of sensitive data. Take the CCPA, for example, which mandates companies to be more transparent in how they collect and use the consumer data of Californians.

A comprehensive data classification policy will enable your organization to know exactly what data regulations apply to it and how to effectively manage data to ensure regulatory compliance, (e.g., restricting access to regulated data). This will help you avoid the bad press, litigations, and fines that can be costly for your business.


Better Organization of Data

A notable obstacle to effective data protection is actually knowing where the data you want to protect resides. It is surprising that a lot of businesses can’t readily tell the locations of their sensitive data or even the size of the data in their systems. Data classification policies can be integrated into software that can search for, identify, and classify data in your systems accordingly.

This not only provides you with information such as the location and size of system data but also ensures optimal organization of your digital information and assets (which makes work easier). It also assists in the implementation of data protection controls such as access restriction and prevention of data leaks.


Greater Awareness

By establishing an official data classification policy, an organization ensures that its employees are informed about how to properly handle, store, and retrieve potentially sensitive data. This provides all staff with a reference point when it comes to data management within the organization, ensuring uniformity and accountability while minimizing the risk of accidental exposure and other unwanted consequences of poor management of data.


Cost Savings

An effective data classification policy will enable your company to evolve measures that will help ensure sound data protection and management. This can save you costs from matters that may arise from security loopholes and poor data management.

A single data breach can be costly. IBM’s 2023 Cost of a Data Breach Report indicates that the global average cost of a data breach in 2023 was USD 4.45 million, a 15% increase over 3 years. Also, the average savings for organizations that use security AI and automation extensively is USD 1.76 million compared to organizations that don’t.


Data Classification Policy Tips

The benefits of having a data classification policy have been mentioned earlier. Here are some tips on how to come up with an effective data classification policy:


1. Determine the Policy’s Objectives and Scope

Defining your objectives and scope before classifying is essential because it will help you align your policy with your business needs and expectations. Key questions here include: What goals and benefits do you want data classification to achieve for your organization? Which persons are the data classification policy meant for? What legal or regulatory requirements apply to your data? What measurement techniques will you adopt to gauge the effectiveness and compliance capability of your data classification policy?


2. Define Your Data Categories

Data classification or categorization can vary according to each organization’s specific needs and requirements. The three most widely used types of data classification are:


Confidentiality-Based Classification: focuses on the level of sensitivity or confidentiality of data, e.g., public, internal use, confidential, and restricted access. Categorization here is often based on the potential harm or impact that may arise if the data is disclosed to unauthorized persons.


Regulatory-Based Classification: involves categorizing data according to the specific regulations or legal requirements that apply to an organization. Examples include data classified as personally identifiable information (PII), protected health information (PHI), or data based on relevant regulatory frameworks such as HIPAA, GDPR, PIPEDA, CCPA, and others.


Criticality-Based Classification: is based on how critical or important the data is to the organization’s operations, e.g., the potential impact on the company if the data were to become unavailable or compromised. Hence, data here may be classified as critical, essential, or non-critical based on how important it is to the organization.


3. Label and Tag Classified Data

To avoid confusion, it is necessary to assign clear labels or tags to data to indicate their classification. You can do this either manually or automatically, depending on the volume and complexity of the data involved. In the manual method, data owners or users attach labels and tags to their data, based on their knowledge and judgment.

In the automatic approach, tools such as software are used to scan and classify data based on previously defined rules or keywords.


4. Determine Access Control, Retention, and Deletion Procedures

Your policy needs to clearly define who is authorized to access and modify data based on their classification as well as the length of time for retaining data and how surplus data will be securely disposed of.


5. Establish Data Handling and Documentation Procedures

Create guidelines that will specify how to handle, share, and store data for every classification level. Also maintain documented records of data classification decisions and policies.


6. Develop Employee Training Programs

For increased productivity, ensure employees are trained on the importance and benefits of data classification, regulatory compliance, and handling practices, as well as their roles and responsibilities in ensuring the success of the policy. Training should be a continuous process that captures the latest data/information classification and management trends, concepts, methodologies, and best practices.


7. Implement, and Enforce Your Policy

Any effective data classification policy should include implementation, and enforcement mechanisms. This will help ensure that your organization’s data is stored, transmitted, and disposed of according to categorization and handling guidelines. You also have to establish incident response mechanisms for responding to unauthorized access and other data security breaches. Always ensure that your data classification standards align with regulatory requirements.


8. Measure Policy Outcomes and Engage in Constant Policy Reviews

It is necessary to monitor, audit, assess and evaluate the impact and value of data classification policy on your data security, privacy, and governance, as well as measure your performance against your objectives and metrics.

Monitoring, auditing, assessing, measuring, and evaluating will help you to periodically review and improve your data classification policy to ensure that it is always effective and relevant. Be sure to demand feedback from your stakeholders and users on the challenges and opportunities they face with data classification while striving to identify any gaps or issues that require attention.


9. Use Data Classification Software

The use of software for effective management of data has been mentioned a few times in this post. In these days of big data, versatile software is important for every organization because it helps in the development of effective procedures for speedily managing large volumes of data, including the implementation of security and protection measures. For example, third-party data classification software can help an organization automate data classification easily and cost-effectively.
