To ensure that only legitimate users can access Software as a Service (SaaS) or Platform as a Service (PaaS) in a Zero Trust framework, implementing robust authentication mechanisms is crucial. Enforcing Multi-Factor Authentication (MFA) and Single Sign-On (SSO) are effective strategies. MFA adds layers of security by requiring users to provide multiple pieces of evidence to verify their identity, making unauthorized access significantly more challenging. SSO simplifies the user experience by allowing users to access multiple services with one set of credentials while maintaining high security standards, particularly when combined with MFA. These measures align with the Zero Trust principle of "never trust, always verify," ensuring that access is granted only after thorough verification of the user's identity.
