Background: Identity and Access Management (IAM) is a critical IT securityframework for managing digital identities and resource access. With roots datingback to ancient civilizations, IAM has evolved from basic authentication to sophisticated methods. Okta, a leading cloud-based IAM platform founded in 2009, excelsin identity management, authentication, and access control. It is recognized for itscommitment to security and adaptability to cybersecurity challenges. As of October2023, Okta maintains its prominent position in the IAM market, acknowledged byGartner’s Magic Quadrant for Access Management, worldwide.

Objectives: The objective of this thesis is to conduct a comprehensive comparative analysis of security services, specifically focusing on their integration with IAMsolutions. This investigation seeks to provide an examination of security serviceslike Multi-factor authentication (MFA) and Single Sign On (SSO) and evaluate theireffectiveness in conjunction with IAM. By doing so, we aim to determine which security approach offers the most robust protection in our digitally interconnected world.

Methods: The primary goal of this methodology is to create a robust, secure,and user-friendly authentication and access management system using Okta withinan IAM framework. This involves the integration of both MFA and SSO features.To kickstart the process, we establish a controlled environment that mirrors thereal-world scenarios. Okta is chosen as the IAM tool, and its deployment involvesmanaging user identities, controlling access, and handling authentication.

Results: The result of the study on the comparative analysis of security servicesusing IAM reveals distinct differences in the effectiveness and features among securityservices. Key findings highlight variations in authentication methods, authorizationmechanisms, and overall security robustness. This comprehensive examination provides valuable insights into the strengths and weaknesses of different IAM-basedsecurity services, offering a foundation for informed decision-making in selecting themost suitable solution for specific organizational needs.

Conclusions: This thesis conclusively demonstrates the efficacy of integrating SSOand MFA into IAM. The incorporation of Biometric Authentication and Time basedOne Time-Password (TOTP) in MFA garnered strong user preference. SSO implementation streamlined authentication, reducing steps and enhancing ease of use.The overwhelmingly positive user feedback and robust security measures validateSSO+MFA as a valuable contribution to IAM, ensuring data security and user confidence.
