Frequently Asked Questions:

Q: What is personally identifiable information (PII)?

A: PII is any data that can be used to identify a specific individual, such as names, social security numbers, or account details. Because it is sensitive, organizations must protect it throughout its entire lifecycle.

Q: What laws govern the protection of PII?

A: Regulations such as HIPAA, which protects health information, and GDPR, which governs personal data in the EU, set requirements for how PII must be handled. Compliance with these laws is a core part of protecting confidential data.

Q: How do organizations protect PII?

A: They use a systematic approach that includes assessing risks, applying protection methods like de-identification, and implementing safeguards during collection, processing, storage, and deletion. This layered approach reduces the chance of a breach.

Q: Why is secure data deletion important?

A: Data that is no longer needed still poses a risk if it can be recovered, so organizations must establish retention limits and secure deletion or purging practices. Properly destroying PII ensures it cannot be exposed after it is no longer required.
