Enterprise identity and access management (IAM) is the discipline of managing digital identities and their access to data, applications, systems and other resources. It addresses two fundamental questions:
In other words, IAM helps organizations ensure that exactly the right accounts exist and that each user can access exactly the right resources based on their job functions.
This article explores the benefits of enterprise IAM, the challenges involved and the key features to look for in an IAM solution. Then it offers a step-by-step procedure for effective IAM implementation.
Robust IAM delivers a wide variety of benefits for enterprises, including the following:
While the benefits of IAM are clear, organizations today face several common hurdles in implementing a robust IAM strategy. First, modern enterprises typically have thousands of identities, including not just employees but contractors, partners, customers and devices, which require different levels of access to various resources. At the same time, those resources, such as databases and applications, are constantly changing, and old systems are being replaced with new ones.
In addition, the rapid adoption of cloud services, mobile devices and remote work has erased the traditional network perimeter. The need to integrate legacy systems and siloed directories with modern cloud applications further complicates IAM implementation. The boom in cloud technology can also exacerbate the problem of shadow IT, as employees embrace easy-to-deploy enterprise cloud identity and access management tools and platforms to improve their workflows. To top it off, add on a growing array of stringent regulatory requirements around data privacy and access control.
As a result of all of these factors, ensuring that the right identity and access management controls are applied consistently and monitored appropriately can be difficult.
To simplify the complex nature of IAM, let's break it down into three components: policies, processes and tools.
Policies form the foundational guidelines that govern identity and access management in an organization. Key IAM policies include
Processes are the systematic methods and workflows that implement IAM policies effectively. They ensure consistent application of policies and maintain identity and access management throughout each user's lifecycle. Key IAM processes include:
Last are the technologies and software solutions used to implement and enforce IAM policies and processes. Key IAM tools include:
Of course, the right IAM solution depends on the specific requirements of your business. You need to understand the different types of users, the systems and applications they need access to, the level of security required, and the compliance regulations your organization must adhere to. You'll also want to consider factors like vendor reputation, total cost of ownership, and training and support options.
That being said, here are some essential features that any modern enterprise IAM solution should include:
With your needs assessment completed and IAM solutions selected, it's time to begin implementation. While each deployment is unique, here's a basic step-by-step guide to help you navigate the process:
Executive support is essential for any project as impactful as IAM. Educate key leaders about the benefits of IAM and how your project aligns with key business objectives. Demonstrate the ROI that your project will deliver through reduced support costs, improved efficiency and enhanced risk mitigation.
Allocate sufficient time to develop policies that balance security and usability, protecting data without overly restricting access. Define clear roles while considering the complexity of diverse job functions. Implement access controls that enforce the principle of least privilege. Investing time in proper planning and design will yield significant benefits down the road.
Begin with a small-scale pilot test to identify and address potential issues. Gradually expand the implementation in phases, allowing for adjustments and learning along the way.
Once pilot phases are successful, proceed with organization-wide implementation and ensure that all systems and users are properly integrated and trained.
Establish a process for periodically reviewing and updating IAM policies to align with evolving business needs, regulatory requirements and security threats. Monitor performance, user feedback and security metrics. Use this data to drive continuous improvement of your IAM deployment.
Like most IT projects, IAM implementation has common stumbling blocks. Lack of planning can lead to inadequate resource allocation and interoperability issues; in particular, be sure to ferret out exceptions to standard procedures during the design phase. Be careful not to create a user experience that is too cumbersome, since they can create resistance or induce users to seek ways around the system and undermine security.
In addition, refrain from creating an excessive number of highly specific roles with lots of granular permissions, since this practice can increase IT team workloads, cause confusion, hurt productivity and introduce security risks. Another potential problem is roles accumulating unnecessary permissions; this access creep violates the principle of least privilege and expands the attack surface.
Finally, remember that each department in your organization may have unique requirements, workflows and security needs. Ignoring the need for cross-department collaboration can result in gaps in security, as policies and procedures might not be uniformly applied.
Robust identity and access management is vital for enterprises, but implementing IAM is not an overnight task. Be sure thoroughly understand the common stumbling blocks and carefully assess your business needs. As you evaluate IAM solutions, look essential features like single sign-on, multifactor authentication, role-based access control, and automated provisioning and de-provisioning.
