The Holistic Z: Selective Encryption gives way to “At-Rest” & “In-Flight” Data Protection with Pervasive Encryption

IBM Z encryption moves the market from a selective encryption model to one that is pervasive. This represents a significant modification in the basic structure of computing and its effect on security will, in my opinion, have a major disruptive effect.

The overall concept is to not introduce a decision layer that says what will or will not be encrypted. Instead, it will be possible to have encryption be part of normal processing. The removal of the decision for selective encryption is a further saving in the overall cost and a reduction in the difficulty in using encryption in the current market.

The Holistic Z

The new IBM Z provides a bullet-proof platform for digital transformation, a base for strong cloud infrastructure (fortified clouds, which can be open, private, public, and hybrid), and allows back-end services to be securely exposed through secure APIs.

IBM have put security at the core of the new platform with “Pervasive Encryption as the new standardAnalytics & Machine Learning for Continuous Intelligence Across the Enterprise, and Open Enterprise Cloud to Extend, Connect and Innovate”.

The Z is arguably more powerful, more open, and more secure than any other commercial offering and makes serious moves in the rapidly evolving domains of Machine Learning, Cloud and Blockchain.

Positive Disruption with Pervasive Encryption 

But for me the focus of my interest comes back to Pervasive Encryption. The Z (“Zero Downtime“) appeals to many, on many different levels but for me it is Pervasive Encryption that piques my interest.

It is a seismic shift and legitimately makes the z14 the go-to platform for organisations who can afford their own and the Cloud platform of choice for those who cannot. The z14 mainframe has a tried-and-true architecture and excels with security features that are built into the hardware, firmware, and operating systems.

True Cost & Performance Mitigation 

The largest barrier to doing full-scale encryption has been the cost of the encryption and the performance load that such activity puts on the computing platform.

Bolted-on solutions that are being deployed have caused system capacity to grow such that there are loads of up to 61% of the system load that is being consumed by security processes. This translates into significant infrastructure costs and performance drags.

Even without the newest advances the Z architecture delivered encryption (selective encryption) more efficiently and with a lower resource expenditure than other platforms.

It delivers over 8.5 times the security protection, at 93% less cost in overall expenditure, and with 81% less effort. The full impact of the faster encryption engine and the ability to encrypt information in bulk on the z14 creates a fully pervasive solution that runs more than 18.4 times faster and at only 5% of the cost of other solutions.

The Threat Landscape & GDPR Compliance 

IBM Z pervasive encryption provides the comprehensive data protection that organizations, customers, and the threat landscape demand.

Here are some stats on that threat landscape:

  1. Nearly 5.5 million records are stolen per day, 230,367 per hour and 3,839 per minute (Source:http://breachlevelindex.com/);
  2. Of the 9 Billion records breached since 2013 only 4% were encrypted (Source: http://breachlevelindex.com/);
  3. 26% is the likelihood of an organization having a data breach in the next 24 months(Source: https://www.ibm.com/security/infographics/data-breach/) ;
  4. The greatest security mistake organizations make is failing to protect their networks and data from internal threats. (Source:https://digitalguardian.com/blog/expert-guide-securing-sensitive-data-34-experts-reveal-biggest-mistakes-companies-make-data)

By placing the security controls on the data itself, the IBM solution creates an envelope of protection around the data on Z.
