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
