How to Lead today's Hybrid Enterprise with Software-Defined Perimeter

Enterprises today are challenged with accessing resources that are not on-prem securely. IT professionals also struggle with today’s digital transformation where control is limited as companies migrate and manage remote users, applications and cloud systems. In addition, IT workloads have evolved dramatically where XaaS and cloud service providers have shifted the IT infrastructure that supports the enterprise away from its users. Enterprise applications and workloads are increasingly supported by distributed infrastructure and capabilities that often stretch across multiple cloud providers, data center providers and XaaS providers. In this shift, often times the security policies and solutions that are protecting critical data and applications remain on physical hardware.

 

The Need for Zero Trust

Zero Trust is a philosophy that changes the way businesses approach network security. The concept is that it’s a security model that redesigns networks into micro-perimeters. Zero trust is generated to limit risks associated with excessive user privileges by adopting these three main elements. First is the fact that zero trust ensures all resources accessed are secure regardless of the location or hosting model. Second, this model adopts a “least privledge” strategy to strictly enforce access control. Lastly, the zero trust model inspects and logs all traffic for suspicious activity.

“Zero Trust demands that CIOs and CISOs move away from legacy, perimeter-centric models of information security – which are useless for today’s digital businesses, no longer bounded by the four walls of their corporation – to a model that is both data- and identity centric and extends security across the entire business ecosystem.” – Forrester

 

What is Software-Defined Perimeter (SDP) and how does will it help?

Software-defined perimeter is an open security architecture promoted by cloud security alliances comprised of vendors and practitioners that specialize in network security. SDP has three main elements for this type of architecture:

-          Identity-Centric: user- or device- based access control; bridges the gap between network security user roles, admin and application access tailored to the specific policies; enables the network to minimize the number of network access

-          Precise, Adaptive, Resilient Security: emphasizes authentication before connection where it can dynamically- provisioned for 1:1 connectivity where each individual will have a unique view of the network tailored to their policy

-          Designed for hybrid environments: Infrastructure-neutral and simplifies security for environments with a mix of cloud and on-prem environments

“By 2011, 60% of enterprises will phase out network VPNs for digital business communications in favor of software-defined perimeters.” – Gartner

 

A Better Approach to Secure Access

It’s virtually impossible to secure your distributed, hybrid IT infrastructure with perimeter security that hasn’t been updated in 20 years. Perimeter-based security solutions such as VPNs, next-gen firewalls and NACs are ineffective against malicious insiders and targeted attacks. These antiquated tools are also complex and expensive to operate.
