Certified Secure Software Lifecycle Professional Practice 2025 – The Comprehensive All-In-One Guide for Exam Success

Software as a Service (SaaS) is fundamentally characterized as a distribution model that delivers software applications over the internet, hosted by a vendor. In this model, users access the software through a web browser without needing to install or maintain it on individual devices. The vendor is responsible for the infrastructure, security, and maintenance, allowing users to focus on utilizing the software rather than managing it.

This model contrasts with traditional software installation on local servers, which requires extensive resources and expertise for maintenance, highlighting the convenience and efficiency of SaaS. Additionally, while SaaS can certainly serve enterprises, the primary definition is not restricted to a private solution, nor is it limited to merely file storage, which are aspects pertinent to other cloud services. Therefore, the correct description emphasizes the hosted nature of the software supplied by the vendor, clearly making option B the accurate choice.
