Challenges of the Shared Security Model

The traditional shared responsibility model between IT and SaaS providers encounters significant challenges due to the nature of SaaS applications. Unlike the typical cloud security model, SaaS often presents difficulties in verifying security controls, as users cannot fully trust the service while also struggling to check its security features. This issue stems from users frequently signing contracts without understanding the associated security responsibilities, as many applications are adopted outside of IT's purview. Consequently, this environment requires a new SaaS security model that assigns clearer ownership for tasks related to identity management and data protection among all relevant teams.
