CISOs Rethink Data Security With Info-Centric Framework

RSA CONFERENCE 2023 – San Francisco – The coalition behind the Data Security Maturity Model has issued a second iteration of the framework, aimed at making it easier for businesses to protect data from leaks.

The coalition, created by Cyberhaven last summer, is led by Sounil Yu, CISO at JupiterOne and includes a range of security leaders from a range of companies, including Boston Scientific, Caterpillar Financial, Fleet, Flexport, Motorola Mobility, Twilio, VillageMD, and others.

During a panel at RSA Conference 2023, entitled Comprehensive Cyber Capabilities Framework: A Tech Tree for Cybersecurity, coalition members laid out a vision for the next generation of data security.

"The ability to protect any type of data across devices, applications, and cloud assets is essential if organizations are to take advantage of the power of modern collaboration and digital transformation without exposing their data to external threats, insider threats, or simple mistakes by well-intentioned users," the coalition said in a statement.

The DSMM aligns to the NIST Cybersecurity Framework and the Cyber Defense Matrix, and to enable a data-centric view, it defines five key functions:

In its second iteration released this week, the maturity model refines each of these pillars to take into account more granular context, such as what server infrastructure is being used, how much is in the cloud, privacy regulations, how employees and others use the data, and how applications, APIs, and non-human endpoints use it, and more — in order to gain a fuller picture of an organization's data footprint.

The Data & Digital Transformation Problem

Richard Rushing, panelist and CISO of Motorola Mobility, tells Dark Reading that a new framework approach was needed given that, in the age of digital transformation, getting arms around all of the data being generated at any given point within an organization simply can't be accomplished by looking at protection in a siloed way. The old concept of seeing data in the context of devices, applications, or the network, needed to be traded for a focus on the data itself, wherever it goes within an organization.

"If you think about what security is enabling, it's the use of data, and ubiquitous access to it," he says. "It's necessary to connect to the network to use the data that's in the network to make better decisions for the business or make better decisions for your customers. But data is found in different places, sometimes it's at rest, and sometimes it's in transit."

He adds that the problem is — quite literally — growing, also necessitating a rethink of protection architecture.

"Data is on a logarithmic curve; for every amount of data that I have next year, it's probably 2.5 times more than the amount of data I had this year," he says. "We're data hoarders, for lack of a better term; no one wants to get rid of people's information who have signed up to websites and forums and everything else, so we have this enormous data sprawl. That, in turn, leaves behind security blind spots."

Further adding to the challenge is the fact that some data is of course more sensitive than other information, and some information doesn't need protecting at all, Rushing points out. And there's dynamism in terms of defining appropriate security levels as data ages.

He uses a product launch to illustrate his point. "With a product release, we start off with a situation where no one knows about it, everything's embargoed, and you're protecting this important intellectual property," he explains. "And the next thing you know, it's released for public consumption. And it's suddenly not top secret anymore, in fact, you want the whole world to know about it."

Rushing says that the framework is meant to tame some of this chaos, and that it can be tailored to large enterprises and small-to-midsized businesses alike. It allows organizations to focus in on a number of practice areas, too — including risk-based decision prioritization, collaboration, continuous education, risk management for vendors and third parties, compliance, being transparent, and incident response and how to recover data.

"I don't want to say it's one size fits all, but it's very close to one size fits all," he explains. "The controls are going to be different depending on the environments, but the approach is meant to be flexible enough to accommodate that."

He says that the framework is a living architecture that the coalition plans to refine and evolve over time. However, the time to make the switch to thinking about things in a data-centric kind of way should start now.

"If you don't start [or] you don't think about this, you're going to get hit in the next 6, 12, 18 months in some way, shape, or form," he warns. "It's not like the Internet is becoming a safer neighborhood and data is the new oil that's going to drive business and attackers alike."
