A Zero Trust Email Security Framework for Governments, Smes, and Cloud Providers

Abstract

It is an important albeit weak communication channel against electronic attacks that is prone to attack on the government services, small and medium-sized enterprises in addition to cloud providers. Conventional perimeter-based security systems are not able to meet the challenges of the current environment of escalating threats, which include phishing, spoofing, and advanced persistent threats (APTs). The paper discusses the increasing demand on enhanced security posture by implementing a Zero Trust Email Security Framework based on the reduction in the number of trust assumptions and applying ongoing identities, device, and content verification in emailing environments. The system combines identity-based access incorporation, behavioral analytics, threat intelligence, and layered encryption to identify, isolate, and eliminate threats on a real time basis. By comparing case studies with simulated attacks, as well as comparative evaluation of email-borne threats handling in varying operational environments, the methodology addresses the need to analyze the possible effectiveness of the framework in a range and variety of environments. The results show that the rates of detected threats have markedly increased as well as fewer successful phishing attacks have been realized. The Zero Trust Email Security Framework would be scalable and flexible to fortify the security posture of cyberspace of both the public and the SMEs as well as cloud providers. Its implementation would be a revolutionary improvement on the way email security is currently handled, where defensive strategy is replaced with resilient one.
