Four core security practices are covered: mapping and classifying sensitive data locations using asset inventories and discovery tools; enforcing strict access controls via RBAC, the principle of least privilege, MFA, and regular access reviews; applying encryption at rest (AES-256) and in transit (TLS/SSL) with proper key management; and conducting regular security audits including vulnerability assessments and penetration testing. GDPR fines of up to 4% of global annual turnover and HIPAA penalties up to $50,000 per violation are cited as compliance stakes. ## Full article daily.dev links to this article rather than hosting it. Read it at the original source: ## Questions this post answers ### What are the GDPR fines for non-compliance with data encryption requirements? GDPR fines for non-compliance can reach up to 4% of a company's global annual turnover or €20 million, whichever is higher. HIPAA penalties range from $100 to $50,000 per violation. These figures underscore why encryption and proper data classification are treated as mandatory rather than optional security layers. _Teams navigating GDPR and HIPAA compliance track regulatory updates and enforcement trends on daily.dev._ ### What encryption algorithm should I use for data at rest in a regulated environment? AES-256 is the recommended encryption algorithm for data at rest in regulated environments. It is considered strong enough to meet GDPR and HIPAA requirements. Alongside the algorithm choice, secure key management practices — including regular key rotation and secure key storage — are essential to maintaining the integrity of the encryption effort. _Engineers hardening data pipelines for compliance find relevant security and encryption discussions on daily.dev._ ## Similar posts on daily.dev - [5 Best Practices for Data Security Every Data Engineer Should Follow](https://daily.dev/posts/5-best-practices-for-data-security-every-data-engineer-should-follow-hwiwgpshn) · Decube · 0 upvotes · 0 comments - [4 Best Practices to Strengthen Corporate Data Security for Engineers](https://daily.dev/posts/4-best-practices-to-strengthen-corporate-data-security-for-engineers-h3kemoxlq) · Decube · 0 upvotes · 0 comments - [Define Data Security: Essential Steps for Data Engineers](https://daily.dev/posts/define-data-security-essential-steps-for-data-engineers-22vubursy) · Decube · 0 upvotes · 0 comments - [Success Starts with Secure Data: A Practical Guide for Enterprises](https://daily.dev/posts/success-starts-with-secure-data-a-practical-guide-for-enterprises-fesiplevh) · Security Boulevard · 0 upvotes · 0 comments - [Data Protection by Design: GDPR Principles and Implementation](https://daily.dev/posts/data-protection-by-design-gdpr-principles-and-implementation-xihbgsiil) · Syncfusion · 0 upvotes · 0 comments --- Tags: [#security](https://daily.dev/tags/security), [#data-engineering](https://daily.dev/tags/data-engineering), [#encryption](https://daily.dev/tags/encryption), [#gdpr](https://daily.dev/tags/gdpr) [View this post on daily.dev](https://daily.dev/posts/4-essential-data-security-considerations-for-data-engineers-nul35b0f0) ```json {"@context":"https://schema.org","@graph":[{"@type":"Organization","@id":"https://daily.dev/#organization","name":"daily.dev","url":"https://daily.dev","logo":{"@type":"ImageObject","url":"https://daily.dev/apple-touch-icon.png","width":180,"height":180},"sameAs":["https://twitter.com/dailydotdev","https://github.com/dailydotdev","https://www.linkedin.com/company/daily-dev-ltd"]},{"@type":"WebSite","@id":"https://daily.dev/#website","url":"https://daily.dev","name":"daily.dev","publisher":{"@id":"https://daily.dev/#organization"},"potentialAction":{"@type":"SearchAction","target":{"@type":"EntryPoint","urlTemplate":"https://daily.dev/search?q={search_term_string}"},"query-input":"required name=search_term_string"}}]} {"@context":"https://schema.org","@type":"TechArticle","headline":"4 Essential Data Security Considerations for Data Engineers","url":"https://daily.dev/posts/4-essential-data-security-considerations-for-data-engineers-nul35b0f0","mainEntityOfPage":{"@type":"WebPage","@id":"https://daily.dev/posts/4-essential-data-security-considerations-for-data-engineers-nul35b0f0"},"datePublished":"2026-08-10T05:45:02.289Z","dateModified":"2026-09-14T06:28:50.141Z","description":"Data engineers face growing pressure to protect sensitive information while maintaining regulatory compliance.
