Pervasive encryption is a consumable approach to enable extensive encryption of data in-flight and at-rest to substantially simplify encryption and reduce costs associated with protecting data and achieving compliance mandates.
The IBM zSystems™ platform is designed to provide pervasive encryption capabilities to help you protect data efficiently in the digital enterprise.

Unified Key Orchestrator for IBM z/OS (UKO for z/OS) provides centralized key management for IBM z/OS data set encryption on IBM Z servers.
The use of AES Cipher keys, supported with z/OS Pervasive Encryption, provides additional attributes that are bound to the key itself such as export controls and supports stronger key wrapping when used in conjunction with UKO for z/OS.
IBM recommends using Cipher Keys for Pervasive Encryption whenever there is a need for keys to remain controlled under equivalently high security, even during key management operations like transfer between systems. For example, as is required by the Payment Card Industry Hardware Security Module Requirements (PCI HSM V1.0 #B2)
Requirements
The minimum system requirements for using AES Cipher keys for z/OS Pervasive Encryption are z14 with CEX6 and ICSF HCR77C1.
All production, development, test, QA, and disaster recovery systems accessing z/OS data sets encrypted with AES Cipher keys must meet the minimum system requirements.
Coupling facility encryption is provided by z/OS V2R3 or later releases. Coupling facility resource management (CFRM) policy statements are used to enable encryption on a structure-by-structure basis.
Ensure system security, Integrated Cryptographic Service Facility (ICSF) configuration, and cryptographic hardware requirements are met.
Consider impacts to dump data sets with coupling facility structure data and cryptographic key management.
Identifying where and how network traffic is protected is labor-intensive. z/OS Encryption Readiness Technology (zERT) eases network discovery by monitoring and recording details about your z/OS cryptographic network protection.

Exploiting the excellent cryptographic performance of the IBM z15™ (all models), IBM LinuxONE Emperor II and LinuxONE Rockhopper II, Linux users can afford to pervasively encrypt their network traffic in a transparent manner using OpenSSL, OpenSSH, and IPSec.
All data volumes assigned to guest operating systems can use pervasive encryption. This applies to:
z/VM Guest Coupling Simulation Support is the software that simulates the hardware and software required to run an MVS sysplex environment as second level guests under z/VM." direction="top">z/VM guestsKVM guests*- All volumes except boot volumes
z/VM® and KVM guests apply pervasive encryption to each piece of guest data at-rest, be it read from or written to a disk.The protected-key dm-crypt technology used protects volume encryption keys from being accessed in plain text format.This protection extends to swap volumes.
Alternatively, a KVM hypervisor can encrypt data at-rest on all volumes, except boot volumes, with dm-crypt technology. Thus, its KVM guests are supplied with encrypted virtual block devices, resulting in transparent data at-rest encryption for all guests.
* Available with Red Hat Enterprise Linux 8.0 and newer distributions, IBM is working with the other Linux distribution partners to include support.
