Understanding the Network Access Authentication Process with Cisco ISE and Active Directory

 Understanding the Network Access Authentication Process with Cisco ISE and Active Directory 🔒

Insightful graphic by Shiraz Rahman that breaks down the authentication flow between Cisco ISE and Active Directory (AD). It’s a great reminder of how critical this process is for securing network access in enterprise environments:

1️⃣ Forward Credentials to AD: ISE sends user credentials to AD for verification.

2️⃣ AD Verifies Credentials: AD checks the credentials and responds.

3️⃣ Receive AD Response: ISE gets a success or failure message.

4️⃣ Retrieve User Attributes: If successful, AD returns user attributes (e.g., group membership) for authorization.
