The traditional use of darknets is to passively monitor malicious traffic in a network. In this paper, we describe an experimental setup that leverages this property of the darknet in a network monitoring setup coupled with several honeypot servers. The honeypots are configured as a decoy to lure cyber attacks on the network. The cyber-security test-bed thus designed enables us to monitor an end-to-end mobile communication network test-bed [1] and detect attacks on the network in real-time. After successful trial runs, the results and alert incidents show that the cyber-security setup is efficient in detecting malicious activity in the network.
