Software as a service (SaaS) radically reduces the challenges to adopting enterprise scale applications – but with these benefits come new security issues you need to be aware of.
For example, when you use SaaS applications you place your data in the hand of third party outside your organization and allow them to access it. You allow data to move across organizational boundaries, sometimes even from one SaaS to another, This creates a situation where you can no longer assume that a request to access data in one of your applications is coming from within the organization.
