This paper examines the role of Identity and Access Management (IAM) systems in modern enterprise environments, with a focus on the challenges introduced by cloud computing adoption. It discusses how companies manage user authentication, authorization, and access controls across heterogeneous IT landscapes. Key issues explored include authorization gaps among cloud providers, the operational complexity of managing legacy and cloud-based systems simultaneously, and the resource demands of maintaining internal IAM functions. The paper also considers whether organizations are better served by internal or externally sourced IAM solutions, concluding that hosted IAM can offer cost-effective advantages, including federated identity management across multiple applications.
Identity and Access Management (IAM) infrastructures are currently available and can help manage services while resolving numerous user authentication, application, and authorization challenges that companies face. With the adoption of cloud computing solutions, companies are discovering that they can more easily respond to evolving business needs while simultaneously controlling the costs of managing and deploying their applications.
An identity and access control system is a crucial technology for the proper management of resources. With a properly implemented IAM system, a business can achieve solid management control of its identity resources, improved tools to meet demanding compliance reporting requirements, record retention, logging, and mechanisms to achieve network access. Most companies within the Fortune 1000 implement IAM tools to boost productivity, enhance IT operational efficiency, mitigate security threats, and improve access and authentication (Strandburg & Raicu, 2013).
Company X must control who can access its technology and systems within the enterprise. Implementing and maintaining this control efficiently and effectively tends to be challenging. Incorporating cloud technologies into a company's infrastructure increases both the risks and complexity involved. Key challenges to access management arise in relation to cloud environments, making it critical to identify best practices for companies to address the challenges involved with managing both private and public cloud users. The enormous challenge concerning information security is access and identity management — specifically, controlling who has access to what technology and systems within the company. Applications and operating systems have diverse approaches to access management. Ultimately, a company that relies on many applications exposes itself to significant challenges in managing its users securely and safely.
Most cloud operators providing any access must do so completely. Managing authorization and access under cloud systems is even more troublesome than managing authentication. The advantage of utilizing a public cloud is that it exposes internal infrastructure activities in ways that are mostly restricted to employees at physical data centers (Strandburg & Raicu, 2013). This is extremely powerful, as it provides developers and frequent users with self-service capabilities, enabling them to receive requested resources much faster. However, most cloud suppliers do not limit who can use this functionality. As a result, once a user has been granted access, they are often able to access all applications and infrastructure. While this provides ease of access, it can be disastrous — a company may find itself in a situation equivalent to granting root access across its entire environment.
There are also significant differences in authorization capabilities among cloud providers. Those that do provide authorization controls often do so in ways that differ substantially from other services. For instance, Amazon Web Services (AWS) has a granular control mechanism for services such as S3; however, for the company's flagship compute offerings, access is often an all-or-nothing proposition. In addition, the elements that can be governed by access control rules vary dramatically across providers. This inconsistency creates difficulties in applying consistent authorization of access across a multi-cloud or hybrid environment.
"Legacy systems, compliance, and scaling IAM demands"
"Internal staffing costs and external IAM alternatives"
A solid IAM solution could assist companies in controlling the complexity and expense of managing user authentication, access, and identity. Most importantly, hosted IAM helps solve the challenge of federated identity, which enables a single authentication credential to be trusted across many applications. As cloud adoption continues to grow, investing in a well-structured IAM strategy — whether internal or externally sourced — remains a critical priority for enterprise security and operational efficiency.
