What Does A Zero Trust Access Do?

What Do Zero Trust Access Do? limits an attacker’s access paths. This principle enforces the concept of least privilege and allows for precise access control across an app’s sub-apps. It addresses several challenges involved in deploying such an architecture. This article discusses the advantages and drawbacks of a zero-trust architecture. To help you make an informed decision about this technology, we’ve outlined a few key points to consider. You can learn more through fortinet.com.

Limits the scope of credentials or access paths for an attacker

Privileged accounts, such as superuser accounts, are the most valuable targets for attackers. Superuser accounts give hackers access to entire organizations. As companies grow, user permissions often expand beyond what is necessary to protect their data and increase the scope of their attack surface. For example, OneLogin researchers found that over 60% of tech leaders had excessive privileges. A Zero Trust solution reduces the size of access paths for attackers by restricting what privileged accounts can do.

Zero Trust is an approach to network access that emphasizes the importance of limiting the scope of credentials or access paths an attacker can access. The Zero Trust concept has been a growing trend in network security for several years. It is characterized by a small set of fundamental beliefs and can be applied widely across the cybersecurity space. This paper introduces zero trust concepts and relates them to business contexts.

Enforces the principle of least privilege

The principle of least privilege is fundamental to securing your network. It requires users to have minimal permissions, such as those needed to perform their jobs. In addition, you limit your attack surface by allocating minimal licenses and making lateral movement easier. Zero Trust access policies can enforce the principle of least privilege across your entire application lifecycle. The following are examples of how they can benefit your organization. 

The first step towards implementing the principle of least privilege is to centralize the management of all privileged access rights and credentials. This requires centralized management of secret accounts and certificates and flexible controls to balance compliance requirements with operational needs. For instance, by centralizing privileged access, you can ensure that only the appropriate users have access to critical systems for business operations. Additionally, a Zero Trust Access approach ensures that every account with access to sensitive information is authorized.

Enables precise access control at the app and sub-app levels

A Zero Trust Decision is a complex algorithm that considers the entire set of contextual information to determine an authorization decision. It is used to authenticate users and block impostors. This decision is made by assessing the user context and device configuration. A Zero Trust Decision considers the context to make a precise decision, and the system dynamically adapts its response based on the underlying data. For example, a Zero Trust Decision considers location, behavior, and device information when deciding whether a user or app is authorized or not.

A Zero Trust Access solution offers granular access control for various corporate and private cloud applications. Its flexible approach enables companies to adapt quickly to workflow changes, add new users, and grant remote access. The cloud-delivered service ensures that users and applications are protected from zero-day threats while allowing for easy adaptation to changes in workflow. A Zero Trust Network, Access solution offers a unique combination of threat intelligence and adaptive access control, including risk scores and security signals.

Addresses challenges of deploying a zero-trust architecture

The Zero Trust approach limits attacker access by adopting the Principle of Least Privilege (PoLP) to determine the attack surface and mitigate the damage caused by security breaches. A zero-trust architecture requires tight policies for all accounts and is built on the principles of least privilege. Enterprise assets are typically comprised of hardware components and digital artifacts. Management of these assets includes cataloging, configuration management, monitoring, and risk assessment. In addition, you should use data to inform resource access requests.

Building infrastructure for Zero Trust requires implementing identity-aware proxies, micro-segmentation, and software-defined perimeter (SDP) tools. Other security controls include VPNs, device approval, and intrusion prevention systems. Moreover, organizations implementing a Zero Trust architecture typically do not have a uniform set of devices. Instead, some operate on multiple clouds, physical data centers, and operating systems, which creates several challenges.
