SDP And VPN For Remote Access : A Comparative Study And Performance Evaluation

Abstract: Remote access is a way of providing access to networks from outside the premises of the network. Virtual Private Network (VPN) is one solution used to provide remote access. Software-Defined Perimeter (SDP) is another solution that is capable of providing access to resources from a remote location. These two technologies use different security models yet provide comparable remote access functionalities. This thesis project investigates the basic components, architecture, and security services of SDP and IPSec VPN. Additionally, a performance evaluation is conducted on SDPand VPN on their connection setup time and network throughput. Our result shows that both SDP and VPN provide secure access, however, SDP has additional features that make it a more secure solution. This thesis project is written in the hopes that it can help enterprises with or without a VPN solution already in place to consider SDP as an alternative solution and learn SDP in comparison with VPN.
