Incorporating privacy checkpoints into the secure development life cycle (SDLC) is the best way to avoid collecting personal data that was not part of the privacy impact assessment (PIA). Privacy checkpoints are stages in the SDLC where privacy requirements and risks are reviewed and validated, and any changes or deviations from the original PIA are identified and addressed. Privacy checkpoints help ensure that privacy is embedded throughout the system design and development, and that any changes are documented and approved.

Collecting more data than necessary for recruitment violates the principle of data minimization, which requires limiting collection to what is adequate, relevant, and necessary. Transparency (A) deals with notice, localization (B) concerns storage jurisdiction, and quality (D) addresses accuracy.

“Data minimization: collect and process only the data that is necessary for the stated purpose.”

The most important consideration for determining the operational life of an encryption key is the volume and sensitivity of data protected by the key. The operational life of an encryption key is the period of time during which the key can be used securely and effectively to encrypt and decrypt data. The operational life of an encryption key depends on various factors, such as the length and complexity of the key, the strength and speed of the encryption algorithm, the number and frequency of encryption operations, the number of entities involved in communication, and the number of digitally signed documents in force. However, among these factors, the volume and sensitivity of data protected by the key is the most critical, as it affects the risk and impact of a potential compromise or exposure of the key. The higher the volume and sensitivity of data protected by the key, the shorter the operational life of the key should be, as this reduces the window of opportunity for an attacker to access or misuse the data.
