Cloud computing services have become ubiquitous, and currently, every organization uses some form of cloud computing service. Furthermore, even if an organization does not allow BYOD for work, employees will still bring their own devices to manage their personal communication while at work. Moreover, in this post COVID-19 era, working from home has become common. These new trends have diminished the previously known boundary between the enterprise-owned trusted network and untrusted outside networks. Therefore, a new cybersecurity paradigm is emerging that is referred to as zero trust architecture (ZTA). A ZTA protects an enterprise infrastructure based on the principles of never trusting and always verifying. The core component of ZTA is a Zero Trust (ZT) algorithm which ensures dynamic access control and continuous monitoring to establish never trusting and always verifying principles. This article provides a novel research direction based on federated artificial intelligence to develop a ZT algorithm.
