📘 Topic: Identity Management
Subject: Information Technology Infrastructure
1. 📌 Introduction
In modern IT systems, many users (employees, customers, administrators) access applications, networks, and databases. Managing who can access what resources is critical for security and control.
👉 To handle this properly, organizations use Identity Management.
2. ✅ Definition
Identity Management (IdM) is the process of identifying, authenticating, authorizing, and managing user identities and their access rights to IT systems and resources throughout their lifecycle.
👉 Simple idea:
It ensures “right person gets right access at right time for right resources.”
3. 🎯 Objectives of Identity Management
- Ensure secure user access to systems
- Prevent unauthorized access
- Manage user accounts efficiently
- Improve security and compliance
- Simplify login and access control processes
4. 🧩 Core Processes of Identity Management
🔑 1. Identification
- Recognizing a user in the system
📊 Example:
- Username or email ID
🔑 2. Authentication
- Verifying the identity of the user
📊 Example:
- Password, OTP, fingerprint
🔑 3. Authorization
- Giving permissions after authentication
📊 Example:
- Admin can edit data, user can only view
🔑 4. User Provisioning
- Creating and managing user accounts
📊 Example:
- New employee account creation
🔑 5. User De-provisioning
- Removing access when no longer needed
📊 Example:
- Deleting account of resigned employee
🔑 6. Single Sign-On (SSO)
- One login for multiple systems
📊 Example:
- One login for email, portal, and cloud apps
5. ⚙️ Identity Lifecycle
📊 Diagram Description
User Creation → Authentication → Authorization → Usage → Modification → Deactivation/Deletion
6. 🧠 Real-Life Example
In a university system:
- Students get login ID when admitted
- They access LMS, email, and library system
- After graduation, account is deactivated
👉 Result:
- Secure and controlled access
- No unauthorized usage
7. ⚙️ Key Components of Identity Management System
- User Directory (database of identities)
- Authentication system
- Access control system
- Role management system
- Security policies
8. 📌 Importance of Identity Management
- Enhances security of IT systems
- Prevents unauthorized access
- Simplifies user login processes
- Improves compliance with regulations
- Reduces administrative workload
9. ⚠️ Challenges
- Managing large number of users
- Password management issues
- Security risks from weak authentication
- Integration with multiple systems
- Insider threats
