Our client is a large multinational company with thousands of employees spread across multiple office locations. They want to enhance the security of their corporate network by implementing 802.1X authentication. The goal is to ensure that only authorized devices and users can access the network resources, reducing the risk of unauthorized access and potential data breaches.

Implementing 802.1X for Network Security


Our client faces the following challenges in their network security:

  • Unauthorized Access: They have experienced instances of unauthorized devices connecting to the network, posing a significant security risk.
  • Guest Access Management: They need to efficiently manage guest access while ensuring these devices don’t compromise the network’s security.
  • Solution

    To address these challenges, MyNet Technologies decides to implement 802.1X authentication on their network infrastructure. This solution will enforce network access controls and strengthen overall security.

  • RADIUS Server Deployment: We deploy a RADIUS (Remote Authentication Dial-In User Service) server, which will act as a central authentication server for all network devices.
  • Switch and Wireless Access Point Configuration: We configure their network switches and wireless access points to support 802.1X authentication with MAB, enabling the devices to act as authenticators.
  • User and Device Identity Management: Employee user accounts and authorized devices are registered in the RADIUS server’s user database. Each device is assigned a unique identity, and user accounts are linked to their respective devices.
  • Certificate-Based Authentication: We decides to use certificate-based authentication to strengthen security further. Devices are issued digital certificates, and only devices with valid certificates are allowed access.
  • Guest Network Segregation: For guest access, a separate guest network is set up. Guests are provided with temporary credentials that allow them to connect to this segregated network, ensuring isolation from the corporate network.
  • Results

    Implementing 802.1X authentication helped our client strengthen its network security, mitigate unauthorized access risks, and efficiently manage network access for both employees and guests.

    1. Enhanced Network Security: With 802.1X authentication, only authorized devices with valid certificates and registered users can access the network, significantly reducing the risk of unauthorized access and potential security breaches.
    2. Centralized Management: The RADIUS server provides a centralized approach to manage user and device identities, making it easier for the IT team to control access and enforce security policies.
    3. Guest Access Control: By segregating guest access on a separate network, the corporate network’s security is not compromised even when guests connect to the Wi-Fi.
    4. Scalability: As our client company grows, the 802.1X-based solution can easily scale to accommodate additional devices and users, without compromising security.
