Zero trust has become extremely popular these days. It’s crucial to understand what it is and what it’s not.
A zero trust security model is a methodical initiative that can help prevent data breaches by getting rid of the concept of trust from the network architecture of an organization. Based on the principle to trust no one and to always verify first, zero trust security is made to offer protection to modern digital settings by using network segmentation, stopping lateral movement, offers a layer 7 type of threat prevention, as well as the simplification of granular user access control.
Zero trust is made by John Kindervarg when he was still the principal analyst and vice president for Forrester Research, according to the realization that conventional security models work on the old assumption that all that’s within the network must be trusted. With this broken trust model, it’s assumed that the identity of the user isn’t compromised and that all users will act responsibility and could be trusted.
The zero trust security model considers trust as a vulnerability. When the network, as well as the users such as the malicious insiders and threat actors, can move freely laterally and then exfiltrate all the data that they’re not limited to. Keep in mind that the infiltration point of the attack isn’t the target location, in most cases.
Zero Trust Security Model
You determine a security surface when it comes to a zero trust. It is comprised of the most valuable and critical assets, data, services, as well as applications in the network. The surfaces that are unique to every organization are protected. Since it only has what’s most important to the operations of a company, the protect surface much smaller than an attack surface, and it’s always recognizable.
Once the protect surface has been identified, you can now determine how the traffic moves within the organization according to the protect surface. Understanding who are the users, what applications are being used, and how they’re connecting is the only method to identify and enforce the policy that makes sure that the access to your data is secure.
Controls will be set in place as near to the protect surface as you can, which lead to the creation of a microperimeter, which moves the protect surface, anywhere it goes. Deploy a segmentation gateway to make a microperimeter. This is also known as a next generation firewall so that that only known and permitted traffic or legit applications can access the protect surface.
How to deploy zero trust?
Achieving zero trust is considered by many as a complex and costly process. But, zero trust will be set up according to your company’s existing architecture and doesn’t require to you get rid of or replace the technology that you currently have. You will find no zero trust products. But you’ll find products that work cohesively with zero trust environments. There are also those that don’t. Zero trust isn’t difficult to deploy, execute, and maintain. You can do this using a five step approach.
- Figure out your protect surface.
- Map out the flow of transaction.
- Create a zero trust security model.
- Create a policy for your zero trust security model.
- Check and maintain.
