How SDP Works?
- An Initiating Host transmits a multifactor token together with user credentials to an SDP controller after receiving it. These credentials contain information such as the kind of device, geolocation, biometric data (for mobile devices), and more.
- An identity provider receives the authentication token and credentials from the SDP controller. This service provider generates, maintains, and manages the data required for the user and device identification. The provider returns access permissions to the SDP controller if identification is successful.
- The SDP controller searches for an Accepting Host that can grant the user access to the resource they’ve requested. The IP address of that host is then sent to the initiating host.
- The Initiating Host connects to the Accepting Host over an encrypted VPN connection.
Software-Defined Perimeter(SDP)
Software-defined Perimeter (SDP) is a network infrastructure that protects cloud-based and on-premise data centers using remote capabilities. The purpose of an SDP strategy is to employ software rather than hardware as the foundation for the network perimeter. The SDP was created by the Cloud Security Alliance in 2013 as a solution for secure networks that minimized the danger of data breaches.
Secure access to network-based services, applications, and systems in public and private clouds, as well as on-premises, is provided by SDP as it cloaks systems within the perimeter so others can’t see them, the SDP technique is frequently referred to as creating a “black cloud.”
