Information classificationis the formal process of evaluating the data an organization creates or holds and assigning it a sensitivity level so the organization can apply the right safeguards. Cybersecurity policies describe classification as the foundation for consistent protection because it links thepotential harm from unauthorized disclosure, alteration, or lossto specific handling and control requirements. Typical classification labels include Public, Internal, Confidential, and Restricted, though names vary by organization. Once data is classified, required protections can be specified, such as encryption at rest and in transit, access restrictions based on least privilege, approved storage locations, monitoring requirements, retention periods, and secure disposal methods.
This is not avulnerability assessment, which focuses on identifying weaknesses in systems, applications, or configurations. It is also not aninternal audit, which evaluates whether controls and processes are being followed and are effective. Option D,information categorization, is often used in some frameworks to describe assigning impact levels (for example, confidentiality, integrity, availability impact) to information types or systems, mainly to drive control baselines. While related, the question specifically emphasizes assessing data and deciding thelevel of protectionbased on risk from disclosure, which aligns most directly withclassificationprograms used to govern labeling and handling rules across the organization.
A strong classification program improves security consistency, supports compliance, reduces accidental exposure, and helps prioritize controls for the most sensitive information assets.
