Sensitive Data Exposure in Files in Plaintext

Issue

Sensitive data stored in files in plaintext

Impacted Frameworks and Reasons

Article 5 requires data minimization, purpose limitation, and integrity. Storing personal data in plaintext files increases the risk of unauthorized access and violates data protection principles.
Article 28 requires that processors apply appropriate security controls. Plaintext file storage shows insufficient protection.

CCPA and CPRA

Organizations must safeguard personal data and provide accurate disclosures about its handling.
Storing data in plaintext files increases the likelihood of unauthorized access and may result in undisclosed sharing or exposure.

HIPAA

PHI must be protected with appropriate administrative and technical controls.
PHI stored in plaintext files is considered an inadequate safeguard and may constitute an unauthorized disclosure.

PCI

Cardholder data must never be stored unencrypted.
Storing cardholder data in plaintext directly violates PCI storage and encryption requirements.

GLBA

Financial institutions must maintain controls to protect customer financial information.
Plaintext file storage indicates a failure to enforce required safeguards.

PIPEDA

Requires meaningful consent and secure handling of personal data.
Storing sensitive data in plaintext prevents demonstrating secure protection and responsible use.

APPI

Requires clear purpose limitation and appropriate data protection controls.
Plaintext file storage undermines confidentiality safeguards.

NIST 800 53

Emphasizes encryption at rest, access control, and secure storage.
Plaintext files violate expected security baselines for sensitive information.

ISO IEC 29100

Requires accountability, transparency, and proper data protection controls.
Storing sensitive data in plaintext provides insufficient protection and weakens accountability.

KSA PDPL

Requires lawful processing and safeguards to prevent unauthorized disclosure.
Plaintext file storage increases exposure risk and may violate required security controls.

UAE PDPL

Processing must remain aligned with declared purpose and protected appropriately.
Insufficient protection of stored personal data undermines compliance.

Qatar PDPPL

Requires strong safeguards to prevent unauthorized access or disclosure.
Plaintext file storage increases the likelihood of data leakage.

Identify and remove any storage of sensitive data in plaintext files. Encrypt sensitive data at rest using strong, industry accepted encryption standards. Use secrets managers, vaults, or secure configuration stores rather than file based storage wherever possible. Review code and platform defaults to ensure temporary files, debug outputs, and cache files do not contain sensitive information. Document and enforce data handling standards that prohibit plaintext storage.
