software-defined perimeter (SDP)

Software-defined perimeter (SDP) is one of several policy-based security frameworks that use identity to control access to digital resources. Essentially, an SDP functions as a broker between internal applications and end users. The framework was developed by the Cloud Security Alliance (CSA) and is based on the U.S. Department of Defense's "need to know" access model.

CSA's SDP framework allows network engineers to segment network resources with security policies in a way that mirrors a physically-defined network perimeter. When the authentication process is complete, trusted devices are given a unique and temporary connection to the network infrastructure. Unauthorized users and devices that do not comply with policy are not able to connect.

With SDP network security software, network administrators are able to dynamically deploy micro-perimeters for hybrid and multi-cloud environments to isolate services. SDP software is purpose-built to give medium and large organizations the perimeter security model needed for zero trust applications and workload-centric network connectivity between on-premises and cloud environments. In addition to limiting attack surfaces, SDP software also eliminates vendor chaos by allowing for installation on any host, without requiring network reconfiguration or hardware appliance lock-in.

What is a software-defined perimeter, and do I need it?
A software-defined perimeter improves enterprise security by making users and devices invisible to outside attacks. Discover the basics of SDP and learn how it can alleviate common security challenges.

Have newer security methods made NAC systems obsolete?
With developments in security methods like zero-trust security and software-defined perimeter, the importance of network access control appears to be diminishing. But NAC systems can still prove relevant at the network edge.

Better security through software-defined perimeter know-how
SDN is redefining the security perimeter. Learn how software-defined perimeter architecture -- like a bouncer at a super-exclusive club -- controls access to sensitive systems and valuable data.

How cloud network services affect transformation and security
Three networking experts explored how cloud network services can affect network transformation, planning and security. Learn more of their thoughts on the role of cloud in different facets of networking.

I Like to add one more important thing here, The global Software-defined Perimeter market is expected to exceed more than US$ 12.50 Billion by 2025 at a CAGR of 33.2% in the given forecast period.
