What is Identity Management and Why is it Important?
Identity management refers to the processes and technologies used to manage digital identities and control user access to applications, systems, and services. With more companies operating online and adopting cloud-based solutions, identity management has become a critical component of IT security and infrastructure. In this blog post, we’ll explore what identity management is, why it’s important, and how it benefits organizations.
What is Identity Management?
Identity management is the creation, management, and use of digital identities for authentication and authorization. The goal of identity management is to ensure the right users have the right access to the right resources at the right times.
At its core, identity management establishes a digital identity for each user that interacts with IT resources. This digital identity contains information such as:
- Contact information
- Roles and permissions
- Access rights and credentials
- Activity logs and audit trails
This digital identity allows organizations to manage and control access to sensitive systems and data based on established policies and the principle of least privilege.
Why is Identity Management Important?
There are several key reasons why identity management is crucial for modern organizations:
Identity management strengthens security by ensuring only authorized users can access certain applications, systems, and data. It reduces the risk of data breaches and account takeovers by limiting access and privileges.
Many regulations and standards like HIPAA, PCI DSS, and SOX include identity management requirements. Proper user access controls and audit trails help demonstrate compliance.
Enhanced User Experience
Simplified single sign-on and self-service password resets reduce login frustrations. Automated provisioning/deprovisioning saves IT teams time onboarding/offboarding.
Increased Operational Efficiency
Role-based access and centralized policies minimize the manual processes associated with account creation and deletion. Automation also reduces mistakes from human error.
Strong identity management results in fewer security incidents, which translates to lower financial losses and legal liabilities. It also reduces help desk tickets for password resets.
Identity Management Security Benefits
Let’s explore some of the key security benefits organizations gain with identity management:
Centralized Access Control
Consolidating identity and access management under one system makes it easier to control access with consistent policies across all applications and resources.
Detailed access logs and activity monitoring give visibility into which users are accessing what and when. This helps detect anomalous behavior and potential threats.
Multifactor Authentication (MFA)
MFA adds an extra layer of protection by requiring users to present two or more credentials before gaining access. This prevents stolen passwords from turning into data breaches.
Automated identity lifecycle management ensures user access is provisioned and deprovisioned immediately when roles change. This reduces the risk of orphan accounts or terminated employees keeping access.
Single Sign-On (SSO)
SSO allows users to access multiple systems with one set of login credentials. This provides convenience for end users while allowing centralized control over their identities.
Just-in-time provisioning grants temporary access to perform a specific task. This minimizes standing privileges and follows the principle of least privilege access.
What is the Goal of Identity Management?
The overarching goal of identity management is to ensure the appropriate level of access for each user across an organization. More specifically, effective identity management aims to:
- Streamline access control with centralized policies and role-based access
- Improve security by limiting privileges and managing credentials
- Increase operational efficiency with automated user provisioning/deprovisioning
- Enhance auditing and compliance with detailed access logs and reports
- optimize the user experience with single sign-on and self-service
- Lower costs by reducing password resets and security incidents
At the end of the day, the purpose of identity management is striking the right balance between security, usability, and efficient access control.
Difference Between Identity Management and Access Management
Identity management and access management are closely related concepts that work hand in hand. However, there are some key differences:
- Creates, manages, and stores digital identity profiles
- Focuses on user credentials, attributes, roles, etc.
- Encompasses single sign-on, storage/sync of identity data
- Identity lifecycle management from onboarding to offboarding
- Authorizes access through policies and rules
- Looks at rights, permissions, and entitlements
- Enforces authentication, password policies, MFA
- Controls access to specific resources like apps/data
Essentially, identity management handles user identities while access management leverages those identities to control access. Identity management creates and manages digital identities while access management deploys them for authentication and authorization.
They work together as part of a broader identity and access management (IAM) framework. Identity management provides the building blocks of user identities while access management utilizes them to enable secure access.
How Does Identity and Access Management Work?
Identity and access management solutions contain integrated modules and capabilities that work together:
Single Sign-On (SSO)
Users log in once with a single ID and password to access connected applications and systems through a unified portal or interface. This enhances convenience and security.
Multifactor Authentication (MFA)
MFA requires users to present two or more credentials before being granted access. This provides an extra layer of verification on top of passwords.
User Provisioning & Lifecycle Management
When a user is onboarded or their role changes, provisioning tools automatically assign the appropriate access and resources. Processes also automatically disable access when a user is terminated or transferred.
Governance establishes and enforces policies for access requests, approvals, reviews, and certifications based on roles. This helps maintain least privilege access.
Privileged Access Management
Strict controls like just-in-time temporary credentials govern access to highly privileged accounts and sensitive systems like root and administrator access.
Reporting & Analytics
Detailed logs, audits, and reports provide visibility into user access activity and security events. They help detect anomalies and demonstrate compliance.
Together, these capabilities provide comprehensive identity and access controls that balance security, efficiency, and optimal user experience.

Identity management plays a pivotal role in securing critical systems and data in today’s digital environments. It provides the foundation for managing user identities and governing access to valuable resources.
With identity management, organizations can achieve benefits like improved security, operational efficiency, regulatory compliance, and better user experience. It integrates with access management to control privileges and enforce security policies consistently across an organization.
As threats evolve and regulations expand, adopting a robust, centralized approach to identity and access management is one of the most effective strategies organizations can implement. With solutions that automate provisioning and control privileged access, companies can significantly reduce their cyber risk profile.

- What is digital identity?A digital identity is the online persona of a user, consisting of attributes that represent a specific user such as username, contact details, identifiers, access rights, credentials, and other associated data. It allows the digital world to identify users over networks and systems.
- How is digital identity created?Digital identities are created when a user is registered in an identity management system. User details such as name, job title, email address, and other attributes are entered into the identity repository. A unique identifier like a username is assigned to represent that digital identity.
- What is access management?Access management controls and manages access to resources and systems based on user identities and roles. It focuses on authorizing or denying access through policies, access rights, permissions, and entitlements. Access management works with identity management as part of a broader IAM approach.
