As the name implies, Zero Trust forces users to prove they are who they claim to be before they can access sensitive assets.
Other security assets assume that activity is legitimate until it’s shown otherwise. Zero Trust believes the opposite, meaning that no action is automatically legitimate, and legitimacy must be proven before access is allowed.
Brief History of Zero Trust Security
In 2010, John Kindervag from Forrester Research Inc. coined the term “zero trust” when he introduced the model of this concept.
The Zero Trust model suggests that trust is a liability, and access must be limited and segmented to prevent bad actors from attacking the entire network from a single access point.
A few years later, Google announced its implementation of zero-trust security into its network. This announcement sparked a growing interest in zero-trust security in the tech community.
What Is the Technology Used in Zero Trust Security?
Zero Trust relies on various existing technologies and processes to secure an IT environment. Here are a few methods that drive a Zero Trust security system:
Reduced Privileged Access and Segmentation
Segmentation serves to break security perimeters up into smaller zones. A network that has files inside of one data center that uses segmentation may have dozens of secure zones. Anyone who can access one zone won’t have access to other areas without additional authorization.
With multi-factor authentication, you need more than a password to get access to any part of the network. Users who activate multi-factor authentication will need to enter another code that gets sent to a different device, usually a phone, to prove further they are who they say they are.
Strict Device Access
Zero Trust security environments also closely monitor the devices that can access the network. For any device to be allowed on the system, the IT security team must first authorize it.
Use Your Existing Technologies to Create a Zero Trust Environment.
Achieving a zero-trust environment can most likely be done with tools you already have in your current IT security toolkit. Use the known technologies that we covered here to create a zero-trust security environment across your network.
