When considering a SaaS-based solution, people often wonder whether their data will be safe “in the cloud”. Security is a major advantage to a SaaS solution. In most situations, security attacks are caused because of the behaviour of legitimate users. According to a recent Forrester Research Report, 70% of all security breaches are caused by internal sources. By locating the system outside the organisation, security risks can be significantly reduced.
Software as a Service is provided to a customer as a subscription based service that is delivered over the internet. SaaS can eliminate high upfront establishment costs and IT maintenance and support. Security measures are required to keep unauthorized people out of your system and prevent them from reading your data whilst it transmitting. More importantly, measures are used to protect internal users from vulnerabilities, and control their accessibility to ensure they only access what they’re meant to.
The OWASP Top 10 identifies the most dangerous security risks that occur on the internet. It provides a framework for evaluating a SaaS application’s security. The major security mechanisms in a SaaS application can include TLS & SSL, PGP, User management, Password & Passphrase requirements and storage, SAML and Audit Trails.
