What is Identity and Access Management? | IIFIS

Identity and Access Management (IAM) is an important part of protecting data and systems in the modern digital environment. We use applications, websites, and services to log in every day. It works behind the scenes to ensure that the appropriate individuals have timely access to the appropriate resources.

If you're interested in learning more about how companies safeguard their digital spaces or simply want to learn more about this subject, you've come to the correct place.

What is Identity and Access Management?

Identity and Access Management, often shortened to IAM, is a system that helps organizations manage who can access their resources. It controls user identities (like usernames) and permissions (like what they are allowed to do).

In simple words, IAM answers two main questions:

• Who are you? (Identity)

• What are you allowed to do? (Access)

This is all about making sure that only the right people can get into sensitive areas of a system and that they can only do the things they are supposed to do.

Think of it like a hotel. When you check in, they confirm your identity (ID check) and give you a keycard that only opens your assigned room (access control).

Why is IAM Important?

This is important for many reasons:

• Security: Prevents unauthorized individuals and hackers from accessing data.

• Compliance: Follows industry and regulatory regulations (such as GDPR, HIPAA, etc.).

• Efficiency: Facilitates quick access for staff members without requiring constant support from IT.

• User Experience: Uses technologies like Single Sign-On (SSO) to make logging in simple and secure.

How Does IAM Work?

It works through a mix of policies, tools, and technologies that create and manage user identities and permissions.

Here are the basic steps:

1. Identity Creation: A user is given a unique identity (like a username and password) when they join a company or system.

2. Authentication: When they log in, the system checks if they are who they say they are. This can involve passwords, fingerprints, or face scans.

3. Authorization: After confirming their identity, the system checks what they are allowed to do.

4. Management and Monitoring: IAM systems keep track of user activity to ensure everything stays secure and correct over time.

What are the 4 Components of IAM?

To understand this better, it helps to know about its four components:

1. Authentication

Authentication is the process of verifying a user's identity.

It's how a system checks, "Are you really who you say you are?"

Common methods of authentication include:

• Passwords

• PIN codes

• Fingerprint scans

• Face recognition

• Security tokens

Today, many systems use Multi-Factor Authentication (MFA), which means using two or more methods to verify a user (like a password plus a fingerprint).

2. Authorization

After confirming who the user is, the next step is authorization.

Authorization decides what a user can and cannot do once they are inside the system.

For example:

• Can they read documents?

• Can they edit files?

• Can they delete data?

Authorization is usually based on roles or permissions assigned to users.

3. User Management

User management involves creating, updating, and deleting user accounts and their access rights.

It also covers:

• Changing passwords

• Updating roles

• Adding new users

• Deactivating accounts when users leave

Good user management ensures that access rights stay current and that no one has more permissions than they need.

4. Central user repository

A central user repository is like a giant list or database where all the user identities and permissions are stored.

It helps:

• Keep track of who has access to what.

• Make authentication and authorization processes faster.

• Provide one place to manage everything.

Common examples include Microsoft's Active Directory (AD) or cloud-based directories like Azure AD.

Having a centralized directory improves security and makes it easier to manage thousands (or even millions) of users.

Key Components of an IAM System

This system often includes these parts:

• Single Sign-On (SSO): Let users log in once and access multiple apps without needing to log in again.

• Multi-Factor Authentication (MFA): Adds extra layers of security.

• Password Management: Tools to create, store, and reset passwords safely.

• Access Management: Controls who can see and do what is inside a system.

• Identity Governance: Ensures compliance by reviewing and adjusting access over time.

• Provisioning and De-provisioning: Quickly giving or removing access when someone joins or leaves an organization.

Examples of IAM in Daily Life

You might not realize it, but you use it every day:

• Log into your email account with a password and a code sent to your phone (MFA).

• Using your Google or Facebook account to log into other websites (SSO).

• Scanning your fingerprint to unlock your phone (authentication).

• Getting access to your company's internal systems when you start a new job (user provisioning).

Best Practices for Strong IAM

To have a strong IAM setup, organizations should:

• Everywhere you can use multi-factor authentication (MFA).

• Review and change user permissions regularly.

• Teach users how to create secure passwords.

• Using Single Sign-On (SSO) can make logging in easier and safer.

• Keep an eye on user activity for strange behaviours.

• Automate the process of allocating and terminating user resources.

• Select reliable and safe IAM solutions.

The Future of IAM

It is evolving quickly. Some trends to watch include:

• Biometrics: More use of fingerprints, face scans, and even voice recognition.

• AI and Machine Learning: Smarter IAM systems that can spot suspicious behaviour automatically.

• Passwordless Login: Moving away from passwords entirely using tools like magic links or biometrics.

• Zero Trust Security: Always verifying users, even if they are inside the network.

The future of IAM is all about making access safer and simpler at the same time.

Identity and Access Management is like the gatekeeper of the digital world. It makes sure that only the right people can get into systems and only do what they are supposed to do.

Understanding the four components - Authentication, Authorization, User Management, and Central user repository, gives you a strong base for how IAM works.

As businesses continue to go digital, IAM will only become more important. A well-managed IAM system not only protects against cyber threats but also makes life easier for users.
