Identity-Based Access Control and Containment Strategies

This document is a technical report that discusses the limitations of traditional static controls in preventing dynamic identity threats. It outlines the challenges faced by organizations in enforcing least privilege access and stopping lateral movement and privilege escalation once credentials are compromised. The report introduces the Silverfort Authentication Firewall, which applies identity-based access and segmentation policies at the authentication layer. This approach allows for real-time detection and blocking of unauthorized access across on-premises and hybrid environments. The document details how Silverfort integrates with Active Directory to monitor authentication traffic and evaluate access attempts based on user identity and behavior. It explains the steps involved in enforcing deny and segmentation policies and containing active threats by isolating compromised identities. The report emphasizes the need for adaptive security measures to effectively manage identity threats and reduce operational complexity in maintaining secure access control.
