Performance Analysis of SDP For Secure Internal Enterprises

Security has become of paramount importance in recent times, especially due to the advent of cloud computing and Internet of Things. With so many devices in the mix, users have the choice of working from anywhere they want. But it also raises the possibility of being able to multiply the impact of any attack by using all devices at hand. Another important aspect to consider is the prevention of access to sensitive data by unauthorized users using authorized machines. Software Defined Perimeter (SDP) provides one such solution. It aims to only allow traffic from authorized users and machines to a hidden resource. This paper discusses the SDP concept and analyzes its performance in the event of a Distributed Denial of Service (DDoS) attack under two different environments - one virtual and one real-world. The results indicate that SDP provides a resilient method for protection again DDoS attacks. While it requires slightly more time for connection setup, it is offset by its exceptional performance even under duress.
