A software-defined perimeter, also known as SDP, is a security framework that restricts access to resources on the basis of an individual’s identification.
The SDP is created to hide an organization’s infrastructure from outsiders while still allowing authorized users access to the infrastructure.
Through the implementation of the SDP approach, the goal of establishing the basis of the network perimeter as software rather than hardware will be attained. An organization that uses an SDP is, in essence, covering its servers and other infrastructure so that it cannot be seen from the outside; however, authorized users are still able to access the infrastructure, therefore allowing companies to maintain a high level of security.
At the network layer, rather than the application layer, a software-defined perimeter forms a virtual barrier around the assets of an organization. This separates it from typical access-based limitations, which limit the rights of users but enable extensive network access.
How Does an SDP Work?
If an SDP is in place, unauthorized users should not be able to connect to a server through any method, even if it is technically available, as SDPs provide access to users only after:
confirming user identification analyzing the status of the
