This category encompasses public marketing materials, published research, general company information available on websites, and non-sensitive operational data. Low risk data requires basic security controls but doesn't need the stringent protection measures required for personally identifiable information (PII), financial data, or intellectual property.

B: Financial records contain sensitive monetary information requiring high-level protection due to fraud risks.

C: Personal health information (PHI) is highly regulated and classified as high-risk under HIPAA and other privacy laws.

D: Customer credit card data falls under PCI-DSS requirements and is classified as high-risk sensitive financial information.
