Data Encryption at Rest is a core data privacy and protection concept that every cybersecurity and GRC professional should understand.
What Is Data Encryption at Rest?
Data Encryption at Rest refers to the practices, processes, or technologies related to data encryption at rest within the context of information security and risk management. Understanding data encryption at rest helps organizations protect their systems, data, and operations from relevant threats.
How It Works
Data Encryption at Rest is applied through a combination of policies, technical controls, and organizational procedures. Security teams implement data encryption at rest as part of a broader security program aligned to industry frameworks and regulatory requirements.
Why It Matters
Organizations that correctly implement data encryption at rest reduce their exposure to cyber risk, improve regulatory compliance, and strengthen their overall security posture.
Key Takeaways
- Understand what data encryption at rest is and how it applies to your organization’s security program.
- Align data encryption at rest practices to a recognized framework such as NIST CSF, ISO 27001, or CIS Controls.
- Regularly review and test controls related to data encryption at rest to ensure they remain effective as threats evolve.
