An Interview With Rich Guski
 

Enterprise Executive sat down with Rich Guski, who recently retired from IBM, to get his insight into current and future security trends he sees. Rich was a key participant in RACF security development and also the architect of several CICS security functions that shipped with RACF for z/OS 1.10 during his 27-year tenure with IBM. He’s also a Certified Information Systems Security Professional (CISSP), as defined by the International Information Systems Security Certification Consortium (ISC)2. 
 
Enterprise Executive:
Rich, what are you currently doing now that you’ve retired from IBM?

Rich Guski: I’m currently doing mainframe computer security consulting work.

EE: Do you continue to stay apprised of current security trends that would benefit mainframe professionals?

Guski: Yes. I still attend and speak occasionally at RACF User Group (RUG) meetings and Vanguard conferences.

EE: What current or future trends do you see in the realm of data security that affect the z/OS environment?

Guski: If you’re the manager of an IT organization, one of your responsibilities, as the custodian of your organization’s data, is to comply with requirements for the security and handling of sensitive data. For many years, the simplest way to demonstrate compliance was to use a well-known mainframe Access Control Product (ACP), such as IBM’s RACF, CA’s ACF2 or CA’s Top Secret, and use the associated ACP tools to generate reports to prove to auditors that you’re protecting the sensitive data. But lately, newly emerging standards for security of sensitive data are complicating this picture.

EE: Can you give us an example of such an emerging standard and what it means for the IT executive. 

Guski: Yes. Certain sets of security requirements, the Payment Card Industry Data Security Standards (PCI DSS), for example, have evolved their own requirements for the security and handling of sensitive data such as credit card numbers that are used by their industry. The PCI Security Standards Council has the responsibility of managing the PCI DSS standard. What makes the PCI DSS standard unique is that, unlike many other regulations, it comes from private industry rather than the government.

EE: Are there other standards and regulations besides PCI DSS that IT executives should be concerned about?

Guski: Yes, there are other compliance frameworks that, while not exactly the same as PCI requirements, nevertheless result in managerial action items similar to those driven by PCI DSS. However, for the sake of brevity, allow me to focus on PCI DSS for now, but be mindful that my conclusions will apply to other sets of sensitive information that a typical IT executive might be responsible for. Look at it this way: PCI DSS could be viewed as a “Standard of Due Care” in case a data breach ever goes to litigation.
