Zero Trust Segmentation
Download the Whitepaper Here →
Excerpt from the Introduction
Traditional enterprise security infrastructures relied on corporate firewalls to protect sensitive resources. This “castle-wall” approach evolved as a convenient way to add security controls, and has shaped enterprises’ existing trust models. Internal users are typically given access permissions with a standard corporate trust level, while external users must go through a stronger authentication procedure to be granted with access. Once access is approved, a VPN is typically used to connect the external users to the corporate “castle.”
Excerpt from the Summary
Of course, this backend access solution must also meet the industry’s security requirements as well as the Zero
Trust Security model. Features like end-to-end network encryption, overlay access control lists (ACL), and of
course authentication, must be integrated with Zero Trust Segmentation. Essentially, segmenting the corporate
network into smaller micro-networks is only the first step. The second step is to integrate user authentication with
the micro-network access as part of the overall Zero Trust Security model.
