Identity Access Management: Role and Significance

Identity Access ManagementMany companies in the accounts and finance sectors are ramping up because of the constant menace created due to data breaches and cyber-attacks. To get a prop cyber security within the data ecosystem, the concept of Identity Access Management (IAM) is getting embraced for protection by organizations and individuals alike. Identity Access Management may be perceived as a line of defence digital diaspora that ensures that only the right individuals have access to the right resources at the right time. In this blog, we shall discuss the paramount importance of Identity Access Management and explore its key components: authentication, authorization, user management, and central user repository.

The Significance of Identity Access Management

Imagine a scenario where sensitive financial data is exposed to unauthorized users or critical systems are compromised due to a weak link in security. Such incidents can lead to catastrophic consequences, including financial losses, damage to reputation, and legal repercussions. This is where Identity Access Management comes into play, as it serves as the linchpin of a robust cyber security strategy.


Authentication is the first line of defence in Identity Access Management. It is the process of verifying the identity of a user, system, or device. This involves confirming the authenticity of the credentials provided, such as usernames and passwords. In more advanced IAM systems, multi-factor authentication (MFA) is employed, requiring users to provide multiple forms of verification, such as a password and a fingerprint scan.

Authentication plays a pivotal role in ensuring that only authorized individuals gain access to digital resources. Without proper authentication mechanisms in place, sensitive information becomes vulnerable to malicious actors.


Authorization comes after a user’s identity has been verified. Authorization determines what actions and resources a user is permitted to access. It defines the boundaries of a user’s digital privileges and enforces the principle of least privilege, granting users only the access they require to perform their specific roles or tasks.

For example, in a healthcare organization, a nurse may have access to patient records, but not to financial data. Authorization policies help prevent unauthorized users from tampering with sensitive information or making unauthorized changes to systems.

User Management

Effective user management is a cornerstone of IAM. It encompasses the processes and tools used to create, modify, and delete user accounts, as well as manage user privileges throughout their lifecycle within an organization. User management ensures that only authorized personnel have access to the systems and resources they need, and it minimizes the risk associated with dormant or former user accounts.

By regularly reviewing and updating user accounts, organizations can mitigate the risk of insider threats and unauthorized access. Furthermore, user management is crucial in maintaining an audit trail of user activities, aiding in forensic analysis in the event of a security incident.

Central User Repository

A central user repository is a centralized database or directory where user identities and their associated attributes are stored. This repository serves as the single source of truth for user information, allowing organizations to manage user identities efficiently and consistently across various systems and applications.

Centralized user repositories come in handy for large organizations with multiple systems and platforms. With an effective Identity Management System, there is a seamless integration between IAM systems and other applications, ensuring that changes in user privileges are reflected across the board. This streamlines the on-boarding and off-boarding of employees and simplifies access management.

The IAM Ecosystem in Action

To illustrate the significance of IAM, consider a scenario in which an employee joins a financial institution. During the onboarding process, their identity is authenticated through a multi-factor authentication system. Once authenticated, the system authorizes access based on the employee’s role, granting access to customer data but denying access to sensitive financial systems. User management ensures that the employee’s account is kept up-to-date, and the central user repository stores their identity securely.

Now, imagine the employee leaving the organization. With an effective Identity Management System in place, the organization can swiftly revoke their access privileges and remove their identity from the central user repository. This proactive approach prevents former employees from retaining unauthorized access, reducing the risk of data breaches and insider threats.
