What Is Zero Trust Security Model?

The zero-trust security model is a cybersecurity method that allows authorized and segregated access to users and devices for accessing the apps, data, services, and systems they require to execute their work. According to Gartner, 60% of enterprises will adopt a zero-trust security posture by 2025.

This article delves deeply into the roots of micro-segmentation and zero trust security, its concepts, the technology and solutions that allow it, and how to deploy and manage it.

What Precisely Is Zero Trust?

Enterprises traditionally rely on a castle-and-moat protection approach, in which everyone outside the company’s network perimeter is suspicious. On the other hand, anyone within the company gets the benefit of the doubt. Indirect trust, the belief that internal users are well said, has led to several costly data breaches, with hackers able to roam laterally throughout the network once they get beyond the perimeter.

Instead of concentrating on user and equipment locations relative to the perimeter that is, whether they are within or outside the private network, the zero-trust approach provides users access to data based on their identities and responsibilities regardless of if they are at business, at home, or somewhere else.

Authorization and authentication occur continually throughout the network with zero trust rather than only once at the perimeter. This approach prevents needless lateral movement across apps, services, and systems, considering both insider risks and the chance of an attacker compromising a genuine account. Limiting who has privileged access to sensitive data significantly limits the potential for hackers to acquire it.

The notion of zero trust has been around for almost a decade, yet it is still evolving and growing. In 2010, Forrester analyst John Kindervag developed the revolutionary security concept. Following that, firms like Google and Akamai implemented zero-trust internally before releasing publicly available zero-trust goods and services.

What Is the Significance of a Zero-Trust Model?

Zero trust interest and adoption have skyrocketed by a slew of high-profile data theft and the worldwide COVID-19 pandemic.

Historically, businesses depended on technology such as firewalls to create barriers around corporate networks. An off-site user may access resources remotely by logging into a VPN and establishing a secure virtual gateway into the network. However, complications occur when VPN access credentials compromise, as in the infamous Colonial Pipeline security breach.

Previously, only a small number of users required remote connection, with most staff working on-site. However, organizations now need to enable secure remote access on a large scale. It amplifies the hazards associated with VPN use.

Furthermore, the perimeter-based architecture creates when an organization’s resources are housed locally in a corporate data center on-premises. Most company resources now disperse across private data centers and numerous clouds, blurring conventional boundaries.

What Are the Fundamentals of a Zero-Trust model?

The zero-trust framework outlines principles for removing inherent trust and ensuring security through constant user and device verification.

The five major concepts of zero trust are as follows:

  • Understand your protect surface.
  • Recognize the security mechanisms that are currently in place.
  • Introduce new tools and designs.
  • Implement comprehensive policies.
  • Monitor and warn.

The principles themselves are subject to the continual feature of zero trust. Zero trust isn’t a one-and-done tactic—it’s a continuous process model that restarts when a principle meets.
