New expert commentary series now available
Rolling Meadows, IL, USA (16 March 2018) — ISACA continues to diversify its content portfolio, launching the Perspectives series, providing expert opinion and commentary from industry leaders on technology topics. Launching the new series is The Vaguely Defined Perimeter, a perspective from Marcus J. Ranum.
A renowned expert on security system design and implementation, Ranum challenges misunderstood notions about perimeter security, starting with stating that organizations often mistake the perimeter as a technology and not an organizing principle.
“Today, I would consider it a knowledge management problem,” said Ranum. “Your perimeter is what you know about it. If you cannot think of your systems as comprising some sort of perimeter, then your management domain is the entire internet.”
In the complimentary Perspective piece, Ranum discuss five factors he believes will impact future security perimeter measures:
- Software as a service (SaaS)
- Software-defined networking
- Big Data
- Internet of Things (IoT)
Touching briefly on each factor, Ranum discusses how the push to the cloud, while cost-effective, isn’t necessarily the safest. Meanwhile, SaaS isn’t any better in helping move the need on IT security. While each factor presents its own security risks, the reoccurring theme is consistent in that you must know about it to manage it. Having big data or even a software-defined network in place doesn’t mean anything if an organization properly understand it or how it affects them.
The Vaguely Defined Perimeter is available now for members and non-members at www.isaca.org/ranum-perspective .
