Pervasive Encryption Simplifies Mainframe Security – Security Intelligence (blog)

On July 17, IBM unveiled its z14 mainframe server, which combines the traditional mainframe hardware with new capabilities in areas such as cloud, cognitive, analytics, application management, blockchain, machine learning and more. Most importantly, z14 includes enhanced security features namely, pervasive encryption to help clients stay one step ahead of cyberthreats.

Access protection inside the mainframe is based on the storage security keys mechanism, which is typical of the hardware. These keys ensure that access to data through the hardware and can be locked or unlocked by every software interface within the mainframe. This makes the hardware security-rich by design. In other words, the access protection hardware feature already works with a software interface in an easy and intuitive way.

Of course, access protection is not the only security measure we need to consider. We must also focus on encryption, especially when security regulations come into play. In the past, mainframe data encryption was based on on-chip cryptography and cryptocards, which limited de facto software interactions with the hardware.

With z14, for the first time in the 50-year history of mainframe technology, encryption is pervasive. This feature adds software-based security intelligence to the mainframes robust encryption mechanism, allowing security solutions to leverage hardware-based cryptography like never before.

Pervasive encryption enables customers to encrypt data at the database, data set or disk level. If they so choose, they can even encrypt 100 percent of their data. The most crucial benefit of pervasive encryption, however, is that it does not require customers to change or adjust applications. Each app will have an internal encryption-decryption mechanism, allowing clients to apply cryptography without altering the app itself.

This feature should alleviate many pain points associated with the EUs upcoming General Data Protection Regulation (GDPR), which governs how companies around the world handle personal data belonging to EU residents. Pervasive encryption can simplify security professionals responsibility to protect such information and help them keep up with the evolving regulations surrounding data privacy.
