Implementing a zero trust security policy: Understanding the basics


Understanding Zero Trust Security Framework: A Comprehensive Overview

Zero trust isn’t a product, but rather a security framework that ensures every user and device accessing a company’s resources is validated. In today’s digital landscape where traditional security perimeters are disappearing, zero trust has become a crucial methodology for protecting data dispersed across various services, devices, and individuals.

Even federal government agencies are transitioning to zero trust, with the Biden administration mandating this shift in May 2021. The executive order on improving cybersecurity and the federal zero trust architecture strategy outline the steps agencies must take to embrace this security approach.

Implementing a zero trust security policy requires best practices such as multi-factor authentication, regular patch management, and access restrictions to specific assets. To begin, companies must define their protect surface by identifying their most valuable data, applications, assets, and services.

Mapping out the network topology, identifying access controls, and continuously validating users are essential steps in establishing a zero trust architecture. This approach requires ongoing effort and can take years to fully implement.

Guidance from organizations like the Cybersecurity and Infrastructure Security Agency can help businesses transition to a zero trust framework. By following these steps and understanding the fundamentals of zero trust, enterprises can enhance their security posture and protect against modern cyber threats like ransomware.
