Federal CIOs Zero In on Zero Trust-Tempemail Zone

Now more than ever,
the US government has focused on proactive cybersecurity measures. Under
President Donald Trump’s proposed budget for fiscal year 2020, the federal
cybersecurity budget would increase to $17.4 billion,
up from an estimated $16.6 billion this year.
The budget increase
shouldn’t come as a surprise, as major data breaches continue to cripple
organizations of all sizes and sectors worldwide while malicious nation-state
adversaries continue to apply pressure, especially on government organizations.
With cybercrime continuing its steep trajectory, it’s projected to cost the
world $6 trillion annually in damages by
2021, according to Cybersecurity Ventures.
Within cybersecurity
spending, one of the areas federal CIOs are eyeing is the concept of zero
trust, due in part to recent reports from the Defense Innovation Board and
the American Council for Technology-Industry Advisory
Council. Zero trust is now front and center for federal CIOs, but
where exactly should they begin?
Beyond Jargon: What Is Zero Trust?
Zero trust fundamentally focuses on establishing new perimeters around sensitive and critical data. These perimeters include traditional prevention technology such as network firewalls and network access controls, as well as authentication, logging and controls at the identity, application and data layers.
While the concept sounds simple, especially as
information security vendors claim to make the road to zero trust easy with their
products, the reality is much more complex. Zero-trust architectures (ZTAs)
require extensive foundational investments and capabilities as well as
extensive logging and control layers that are largely in the traditional IT
stack more than a plug-and-play security technology.
Getting Started
Federal IT environments are complicated, and as CIOs take a closer look, they will see in many cases they’re already notionally on a path to zero trust. There are a number of foundational requirements that are not unique to zero trust that map back to the DHS’s Continuous Diagnostics and Mitigation (CDM) program.
To get started on the road to zero trust,
government organizations should begin with CDM Phase 1 requirements that focus
on understanding what’s on the network. The CDM Phase 1 requirements include:
Automation of hardware asset managementAutomation of software asset managementAutomation of configuration settingsCommon vulnerability management capabilities
By following these requirements, federal CIOs
can begin to gain a true understanding of the sheer amount and sensitivity of
the data they hold.
The Obstacles in the Road
ZTA generally assumes that an enterprise has fully embraced concepts such as DevOps and has limited legacy data and applications. Federal networks are different because they have been around longer and have more legacy technology than most enterprises. They also leverage secure facilities for access to sensitive data and are already under constant attack from nation-state adversaries.
Beyond CDM Phase 1 requirements, federal CIOs
should shift focus to identifying critical data in their networks and building
secure applications and identity management systems around that critical data.
Once sensitive data has been identified, network and application logs should be
used to determine who accesses the data on a regular basis; this information
can be entered into traditional network-layer and application-layer controls,
such as firewalls and role-based access to applications and data.
Today, one of the biggest decisions that federal CIOs must make is how they shift their development requirements for current, next-generation and legacy applications. With the advent of ZTA, it’s likely that CIOs require all applications to use a centralized identity, credential and access management solution. But when it comes to current applications, there is a significant cost to retrofit access controls (adding firewalls and application gateways) and it’s unclear who will foot the bill between security: IT or application development teams.
The final challenge will be around legacy
applications such as mainframe applications, which are common in data-intensive
government lines of business applications. Without a straightforward way to add
layers of protection and monitoring to these systems, CIOs will either spend
money to completely redesign these systems or accept that a true ZTA is still
beyond their reach or the reach of their budgets.
