SDN (Software Defined Network) has attracted the attention of many technology giants from various segments such as VMware, Juniper, Cisco, HP, IBM, Google, China Telecom, Huawei and others by providing more virtualized services that can be scheduled, managed and monitored faster, more efficient and in a less costly manner than the usual solutions. Defining routes, switching, QoS treatment and security policies that happened in stocky and specific hardware now perform their duties in higher layers of software, installed on virtualized machines. But how can we test this? First, we'll address an overview of the SDN architecture, soon after, it will be explained how to find SDN controllers, and if present in our network, steal critical information so that we can proceed with our exploitation. In the end, we will take possession of the controllers and see what actions you can perform. There will be a smattering of codes for metasploit that will be demonstrated. Can a controller can control us? We'll see.
