The network is a key component in application delivery and is often a direct or indirect target of security attacks
such as DDoS and BGP hijacking. Mitigation strategies often involve using a third party cloud service without any
visibility into whether the mitigation is working well. Using real life examples, we will show how one can measure
the user perceived impact of an ongoing attack, as well as identify which aspects of the mitigation are not working
as desired. With this detailed availability and performance data at the various layers, financial firms can learn how
to better manage ongoing attacks.
