Why Choose This Project

With the rise of BYOD (Bring Your Own Device) and networked environments, unauthorized devices connecting to corporate networks pose a serious security threat. Rogue devices can be used for data exfiltration, malware distribution, or unauthorized access. This project detects and alerts administrators about unauthorized or unknown devices on a network, helping organizations maintain network integrity and compliance.

What You Get

• A network monitoring platform to detect connected devices.

• Real-time identification of authorized vs unauthorized devices.

• Alerts and notifications for rogue devices attempting to access the network.

• Device tracking by IP, MAC address, hostname, and connection timestamp.

• Reports and dashboards for network administrators to review device activity.
