In today’s rapidly digitalizing world, businesses grapple with the challenging task of managing exponential data growth. Companies face heightened cyber threats due to this data proliferation and increasing dependence on cloud services. The need of the hour is robust data security. However, not all data is born equal; discerning which portions require higher protection levels can be complex. This is where the significance of information classification steps in.

What is Information Classification

Information classification is the act of categorizing data by its sensitivity level. It organizes data into meaningful groups for enhanced protection. This may include setting apart data like financial records from public relations materials.

The classification process delves into asset evaluation, assigns sensitivity, and categorizes data as Confidential, Classified, Restricted, Internal, or Public. The objective here is to foster uniformity in classification, ensuring that data is safeguarded in a manner befitting its sensitivity.

The Importance of Information Classification

  • Ensuring Data Security: At its core, information classification is about safeguarding critical corporate data. It involves segregating distinct types of information to ensure controlled access. For instance, financial records must be isolated from public relations files to protect sensitive customer info, invoices, orders, and user data.
  • Identification & Categorization: The primary goal is determining which data requires heightened security. By identifying and assigning sensitivity levels to different information assets, businesses can determine what needs safeguarding and devise a structured approach to its protection.
  • Optimized Risk Management & Resource Allocation: A well-defined classification system not only ensures effective information protection but also optimizes the management of potential risks and the allocation of resources. Such a system ensures that the most sensitive data is given the highest priority regarding protection.

Sensitive Information

  • Description: While this data requires protection, its security criteria aren’t as stringent as Confidential data. Nevertheless, there’s an emphasis on ensuring that sensitive data isn’t accessed indiscriminately.

TCS employs these categories as a global IT service provider to manage its vast and diverse data. This data management and categorization are pivotal for the company’s information security management and hold historical significance.

It’s essential to note that while TCS has these categorizations in place, such classifications can differ between companies, underlining the need for alignment with unique security requirements. Learn more here.

Additional Information Categories in TCS

The additional information categories in TCS that act as subsets or are related to the aforementioned main categories include Technical Specifications, Marketing Details, and Administrative Information.

  1. Technical Specifications: This category pertains to the technical aspects of information. In a broader context, technical specifications would encompass detailed descriptions and criteria for making products, services, or projects. These might relate to software development, system architecture, and hardware requirements within TCS.
  2. Marketing Details: This category would include any information concerning the marketing strategies, campaigns, customer demographics, and other data pertinent to promoting TCS services and products. Such details would be vital for the company’s public relations and business growth.
  3. Administrative Information: Encompassing a broader range, administrative information would cover various aspects of company management, ranging from employee data, and office management details, to policy documents and procedural manuals. Considering its nature, this information could be connected to both public and internal classifications.

Sensitivity-Based Classification

Sensitivity-Based Classification

Sensitivity-based classification categorizes data depending on the potential harm that might result from data breaches, misuse, or inappropriate access. There are generally four classification levels, with Level 1 being the least sensitive and Level 4 being the most critical.

  • Level 1 (Unrestricted Public Data): This level is the least sensitive and pertains to unrestricted public data. According to the data from Jewell College, this encompasses student and employee information, facilities data, and financial statements. Although it is public data, there’s still an emphasis on maintaining its authenticity and integrity.
  • Level 2 (Internal Data): This level is primarily for internal use and is not explicitly labeled as public or of higher sensitivity. It may include proprietary information that could be essential for the organization’s operations, requiring encryption for added protection.
  • Level 3 (Non-Public, Low Risk): Data at this level is intended for internal use and carries a low risk. An example of such data would be non-public information with personal details that might be subject to specific data protection regulations, such as the Freedom of Information and Protection of Privacy Act (FIPPA).
  • Level 4 (Highly Sensitive Data): This is the most sensitive data category. Given the high risk involved, this level requires the strictest protection measures, especially when it includes Personally Identifiable Information (PII). Due to its critical nature, it demands extra safeguards, with stricter usage rules, especially when stored on servers. This category includes personal health records, payment card info, and student/employee records.

Emphasis on Proper Handling and Protection Based on Data Sensitivity

Objectives of Sensitivity-Based Classification

The primary objectives of this classification include ensuring data protection, compliance with relevant regulations, risk management, efficient resource allocation, and appropriate incident response. It helps organizations define clear categories (like PII or financial data) and set corresponding security measures and access controls.

Implementation and Management

Understanding the data landscape, including taking inventory, mapping vulnerabilities, and identifying and labeling data (either manually or automatically), is essential. Implementing policies based on these classifications governs how data is stored, transmitted, and disposed of. Furthermore, it’s imperative for organizations to educate staff, monitor compliance, and regularly update policies.

Utilizing technological controls such as Data Loss Prevention (DLP) systems and encryption tools is vital before enforcing these policies. A strong governance framework is crucial to support data lifecycle management.

Involvement and Education

Getting business buy-in is pivotal for the success of any classification policy. Unless the entire business understands the rationale behind the policy, compliance might only be superficial. Data classification isn’t the sole responsibility of security teams; education plays a significant role in improving overall information security.

Regular reviews, stakeholder feedback, and impact measurements can further enhance the policy’s effectiveness.

Best Practices

To achieve optimal results, organizations should prioritize their most sensitive data, automate classification processes where feasible, and constantly adapt to the changing data landscape. Ensuring proper security controls are in place, matched to the classification levels, and ongoing maintenance and monitoring are also paramount for protecting dynamic data.
