Cloud security refers to the practice of protecting the integrity of cloud-based applications, data and virtual infrastructure. The term applies to all cloud deployment models (public cloud, private cloud, hybrid cloud, multi-cloud) and all types of cloud-based services and on-demand solutions (IaaS, PaaS, SaaS).
Software-as-a-Service (SaaS) is a software licensing and distribution model in which a service provider hosts applications and makes them available to customers over the Internet. Also referred to as “on-demand software,” “hosted software,” and “web-based software,” SaaS is one of three main components of cloud computing—which is one of the foundational elements of digital transformation.
Zero Trust is a strategic cybersecurity model designed to protect modern digital business environments. Zero Trust is centered on the belief that organizations should not automatically trust anything, whether it’s outside or inside its network perimeter. Zero Trust models demand that anyone and everything trying to connect to an organization’s systems must first be verified before access is granted.
