A Comprehensive Guide to Data Security: Classify, Categorize, Own

As we move forward from the foundational understanding of data security, it’s crucial to dive deeper into the intricacies of your data landscape. The next step in securing your data lies in meticulous classification and ownership—crucial processes that go beyond mere recognition and into the realm of strategic management. In this second installment of our series, "Classify, Categorize, Own" we peel back the layers of data’s complexity, guiding you through the vital task of identifying not just where your data is, but what it is, how sensitive it is, and who should be responsible for it. By doing so, we help you move towards a more nuanced security strategy that doesn’t just protect your data but does so intelligently and with precision.



 

Sensitive Content Classification:

Sensitive Content Classification has evolved into a sophisticated process that leverages advanced technology to thoroughly scan and analyze the vast amounts of data within an organization. This includes parsing through raw text from documents and databases, performing Optical Character Recognition (OCR) on image files, and examining images within documents to accurately identify and categorize sensitive information.

Using complex algorithms and pattern recognition, this system is designed to detect unique identifiers such as social security numbers, credit card information, and healthcare record numbers. These identifiers are pinpointed not only through direct matches but also by analyzing the context provided by associated terms and phrases. This contextual understanding is key—it involves an extensive library of terminology related to legal, financial, healthcare, and privacy sectors, ensuring nothing slips through the cracks.

The real power of Sensitive Content Classification comes from the integration of these patterns and contextual clues into comprehensive policies. These policies are constructed using complex logic to correlate identified data with pertinent regulatory compliance measures and privacy laws. By associating sensitive data with the correct classifications, organizations can streamline their compliance processes for a variety of regulations, including but not limited to HIPAA for healthcare information, PCI-DSS for credit card security, CCPA and GDPR for data protection, GLBA for financial information, as well as FERC/NERC and CMMC for energy and defense sector standards, respectively.

This enhanced classification strategy not only ensures the highest level of security for critical data but also shields organizations from potential legal implications by maintaining strict compliance with all relevant regulations. The benefits of such an advanced classification system are clear: it allows businesses to maintain the integrity and confidentiality of sensitive data, thereby upholding their reputation and ensuring peace of mind for both the organization and its stakeholders.

 

Data Type Classification:

Data Type Classification hinges on understanding how data is utilized within an organization. This insight directly informs the crafting of security measures that are not only robust but also precisely attuned to the needs of different data types.

For instance, User Data often resides in areas like Home Folders, Computer Profiles, or platforms such as Microsoft OneDrive. This category is personal, meant for the user's eyes only, and typically includes sensitive information, possibly even Personal Identifiable Information (PII) which ideally shouldn't be retained by the organization. The content here often supports other documentation and isn't usually the primary data source.

When it comes to Department Data, the boundaries extend to allow for departmental collaboration. Access controls need to be calibrated to permit departmental sharing while securing the data from wider exposure. In certain scenarios, this data may need to be shared across departments. While primarily supportive in nature, department data can also include essential records and frequently contains sensitive information.

Public Data is designed for broad internal dissemination. This is the realm of company announcements, policies, and other non-sensitive communications. Security protocols for public data ensure it’s accessible company-wide, and safeguards are in place to prevent the inclusion of sensitive information.

Application Data is the lifeblood of operational software — created, manipulated, or used by applications and occasionally directly by employees. Its security is contingent upon the application's role and the data's sensitivity.

Each data type's classification lays the groundwork for a layered data access hierarchy, effectively protecting against unauthorized access. This structured approach not only ensures data security but also aligns with an organization’s workflow and data usage patterns, fostering a secure yet flexible data environment.

 

Ownership Classification:

Effective data governance is significantly enhanced by clearly defining data ownership. This classification system delineates the hierarchy of data stewardship, ensuring that each tier of ownership is aligned with the appropriate level of data access and responsibility.

At the top of this structure is the Department Division (e.g., Human Resources, Finance, Information Technology, etc.), which provides a macro view of data custodianship. By identifying the broader division, an organization clarifies the overarching ownership and access rights, framing who is ultimately responsible for various data sets.

Drilling down, the Functional Department (e.g., HR Benefits, Finance Payroll, IT Security, etc.) is pinpointed to assign ownership at a more granular level. This tier specifies which departmental units should manage the data, enabling more precise control and access aligned with departmental functions.

The capstone of this structure is the Primary Data Owner. This individual has the ultimate authority over the data, deciding who has access, the type of data under their purview, and how it should be managed.

Supporting the Primary Data Owner are Delegated Data Owners—supervisors and managers who often have the most intimate knowledge of the data. Their insights are vital for addressing intricate data-related inquiries and for assisting the Primary Data Owner in making informed decisions.

This classification is not merely administrative—it's a cornerstone of regulatory compliance. With laws like the GDPR mandating dedicated Data Officers to steward personal data, the identification of Data Ownership is not optional but a critical component of legal and ethical data management. Establishing clear lines of data ownership supports these Data Officers in fulfilling their obligations to protect and properly handle sensitive information.

 

Eevabits Data Risk & Security Assessment

Transitioning from the foundational concepts outlined in this guide to practical implementation, the Eevabits Data Risk & Security Assessment emerges as a pivotal tool. This assessment directly enhances your data security across three critical areas:

For Sensitive Content Classification. The Assessment quickly identifies where sensitive data lives and how it's protected, offering concrete steps to improve policies and maintain compliance with laws like HIPAA or GDPR. It’s a direct path to securing your sensitive information against breaches and penalties.

Regarding Data Type Classification. It provides a clear breakdown of data types and their respective security needs within your organization. This allows for the creation of specific access controls and security protocols, minimizing the risk of unauthorized access and data leaks.

Concerning Ownership Classification. The Assessment clarifies who is responsible for what data, streamlining data governance. It ensures that every data owner is aware of their responsibilities, improving oversight and response to potential security incidents.

By incorporating the Eevabits Assessment, your organization gains a concise, actionable plan that strengthens your data security posture in these essential areas, leading to a more secure, compliant, and well-managed data environment.
