Zero-Trust is the reigning popular governance model for implementing security on networks. While older security policies assigned users access based on a set of rights, which often conferred access to numerous systems, Zero-Trust provides the least possible access necessary to perform activities on the network. A Zero-Trust network also continuously monitors devices and resources across the network, tracking users, activity, and changes—all designed to help identify and stop potential threats.
At our core, humans are trusting creatures. Whether we’ve just met someone at the local coffee shop or we’re doing important, highly sensitive work online, we tend to assume the best rather than anticipate the worst. The very thought of doubting motivations and intent runs counter to everything we hope to build in our relationships, both immediately and over time.
Zero-Trust fights this human propensity—and does so for the good of your network. The National Institute of Standards and Technology (NIST) recently published a paper defining Zero-Trust as “an evolving set of cybersecurity paradigms that move defenses from static, network-based perimeters to focus on users, assets, and resources.”
To better understand what this means, think of Ronald Reagan’s famous “trust but verify” quote during the Cold War. In many ways, Zero-Trust takes the polar opposite approach: verify before trusting anyone or anything along your network. Based on such a tenet, it’s obvious that authentication and authorization are foundational to any Zero-Trust approach. Before establishing access, both user and device must gain proper clearance.
As with nearly everything else in your world, cybersecurity has changed over time. Remember when the worst threat Hollywood could imagine involving cybersecurity was someone dialing into a remote server over a 9.6 baud modem and stealing a few secrets? Hacking is still a threat—don’t get me wrong—but it’s so much more profitable now to engineer a successful phishing scheme and then lock up someone’s data and demand a fortune in Bitcoin as ransom.
So what’s changed? Well, there are three specific realities behind this evolution to a Zero-Trust model:
Rapid technology advances. Breakthroughs continue at an exponential rate, creating the need to “keep up.” Whether it’s cloud computing or the next big thing on the horizon, network security is more reliant than ever on proper verification always preceding trust at any level.
Remote access points. Long before COVID-19 accelerated the trend, individuals were accessing networks from a variety of locations and devices. This created the need to move defenses away from physical locations exclusively and to insert them throughout the network, keeping tabs on everything from APIs to access points.
Resource-focused protection. Since the physical location alone no longer drives security, attention shifted to protecting individual elements of the network, such as users, assets, and workflows. Today, something as seemingly benign as an unusual uptick in CPU utilization can red-flag a potential security issue.
If you think back to how far we’ve come—when firewalls and antivirus were the workhorses of cybersecurity—to where we are now, it’s a sobering realization knowing that even Zero-Trust will have to evolve into something new down the road.
At the heart of any Zero-Trust model is visibility and transparency. The problem with yesterday’s cybersecurity is that it was developed to protect a finite realm, typically involving the corporate network and some remote devices.
Today, the distance between remote end-devices and the network core requires better visibility into what and who is on our network, and what they are doing at all times.
Remember, verify, then trust, and now add, verify again. That means we verify when they enter the network, we verify when they access items on the network, and we verify when they change anything on the network, even themselves.
This level of visibility requires a combination of old-school security monitoring combined with today’s advances in IoT-capable devices, workload monitoring and governance, and a slew of advanced AI and machine-learning based systems all working together to collect data, track, and report in real-time the status of everything happening on your network. From is the identity of those in your network, the knowledge of whether software, middleware and APIs have been updated to the latest versions, the status of your existing systems, and the comparison of baselines against real-time, nothing is taken for granted in a Zero-Trust environment.
If you’re reading this and realizing you don’t already have the tools in place for this kind of insight, well, you’re not alone.
In 2019, Cybersecurity Insiders reported that only 15 percent of organizations had completed a transition to a Zero-Trust security model.
Interestingly, the question of how to implement a Zero-Trust model requires enforcing the same rules on the security vendors offering solutions.
Verify their credentials, then trust that they can do what they promise.
Epoch Concepts work with dozens of cybersecurity solution providers, each offering its own flavor of Zero-Trust. Most map back to guidance released by NIST and other government-focused agencies.
