The traditional approach to security has primarily centered around fortifying the network perimeter. Once users are inside this perimeter, they are presumed to be trustworthy and are typically granted broad access to numerous corporate resources. However, the rise of both internal and external malicious actors has highlighted the flaws in this perimeter-based model, and several notable cyberattacks have demonstrated its inadequacy. A hybrid workforce, accelerated cloud migration, and software as a service (SaaS) adoption have expanded security perimeters and attack surfaces. The implicit trust security model and blindly trusting attributes like originating network or domain membership are no longer suitable in light of modern cybersecurity threats.
