Masking vs. Encryption for Non-Production Data

Encryption scrambles data using mathematical calculations and algorithms, and is best used for securing data that needs to be returned to its original value - e.g. production data or data in motion. Encryption only offers protection as long as the corresponding encryption keys are safe. A hacker who compromises the right keys is able to decrypt sensitive data, restoring it to its original state.

Data breach risk demands stronger security measures

With data breach incidents regularly making the news, organizations are increasingly scrutinizing the tools they've deployed to protect sensitive information. Encryption and decryption technologies represent a mainstay approach to securing data. While these solutions - including hashing-based, asymmetric, and symmetric encryption - may be effective for securing data-in-motion or data resident in hard drives, they are ill-suited for a variety of use cases.

What is data encryption and what are its potential security flaws?

Encryption scrambles data using mathematical calculations and algorithms, and is best used for securing data that needs to be returned to its original value - e.g. production data or data in motion. Encryption only offers protection as long as the corresponding encryption keys are safe. A hacker who compromises the right keys is able to decrypt sensitive data, restoring it to its original state. Another failed use case is the protection of non-production data used for development, testing, training, and support. Encryption fails to adequately protect these environments - which often represent 80% of the surface area of risk- since phishing and other schemes to obtain user credentials allow hackers to bypass encryption measures.

What is data masking and what are its advantages over encryption?

For non-production environments, data masking solutions provide a superior approach to data anonymization or data obfuscation. Data masking replaces sensitive information with realistic yet fictitious data, completely neutralizing risk in downstream environments. There is no "master key" and scrambled data cannot be returned to original values. Delphix delivers masked test data in a consistent, repeatable fashion so developers and testers receive production-quality data, without the production risk.The resulting secure, anonymized data cannot be reversed to original values and is safe to distribute to stakeholders such as developers, testers, or analysts.

Delphix's Data as a Service platform represents a unique data masking solution that seamlessly integrates masked data creation with masked data delivery. By providing on-demand access to secure data sets, Delphix customers get fast, flexible--and secure--data in minutes.

By combining a data masking solution with Data as a Service, Delphix provides a triple benefit to enterprise customers: enhanced security, greater agility, and lower costs for applications projects.
