Network Access Control Configuration

Securing Network Access with Cisco ISE

To enhance network security and compliance, Veolia implemented Network Access Control (NAC) using Cisco ISE across all switch ports for LAN and Wi-Fi networks.

What we did?

Applied NAC configurations to secure access for authorized devices only.
Updated policies to accommodate corporate devices like printers, meeting room systems, and Chromebooks.

How we did it?

Policy Application and Testing
Applied NAC configurations to all switch ports and tested for authorized device access.
Updated device MAC addresses in ISE policies for seamless access.
Device-Specific Configurations
Tested corporate devices (e.g., printers, meeting systems) and added them to authorized groups.
Ensured compatibility for laptops and Chromebooks by updating certificates.
Validation and Compliance
Collaborated with site teams to validate device access.
Ensured configurations met Veolia’s compliance and security requirements.

The Outcome

The implementation enhanced network security, restricting unauthorized device access while ensuring seamless connectivity for corporate devices. This project reinforced Veolia’s commitment to maintaining a secure and compliant IT environment.
