Zero Trust: Definition
Zero Trust has become one of cybersecurity’s most used buzzwords.
Zero Trust is a strategic approach to cybersecurity that secures an organization by eliminating implicit trust and continuously validating every stage of a digital interaction. Rooted in the principle of “never trust, always verify,” Zero Trust is designed to protect modern environments and enable digital transformation by using strong authentication methods, leveraging network segmentation, preventing lateral movement, providing Layer 7 threat prevention, and simplifying granular, “least access” policies.
Never trust, Always verify
Zero Trust was created based on the realization that traditional security models operate on the outdated assumption that everything inside an organization’s network should be implicitly trusted.
A traditional approach will assume that after the sign on and pass though the firewall, everything and everyone on the network is safe.
Zero trust, says, no way this is true, so the only way to be sure is to make constant control of the authorities and the location of the user, using the least permission level always force the security to constantly ask, is the user allowed to do this?
Zero Trust Model
We can explain the Zero Trust Approach as 5 components, which I will detail as follows,
- Devices – Addresses the need to isolate, secure and control all network-connected-devices, which have proliferated with the ascend of mobility and the use of Internet, creating an enormous vulnerability for attackers to exploit.
- Data – Refers to methodologies for classifying and categorizing data, combined with technology solutions for securing and manage data including encryption of data in transit and at rest.
- Networks – Refers to the ability to segment networks or isolate network assets and control communications among them. A critical issue in a Zero Trust approach.
- Workload – Means securing the front-to-back application stacks that run critical business processes.
- People – Encompasses strategies to limit and enforce users access, including technologies for authenticating users and continuously monitoring and governing their access privileges.
