The Controller Shield project proposes to create a repository called the Unified-Security Plugin (USecPlugin). The Unified-Security Plugin is a general purpose plugin to provide controller security information to north-bound applications. The security information could be for various purposes such as collating source of different attacks reported in SB plugins / suspected controller intrusions or information about trusted controllers in the network. Information collected at the plugin may also be used to configure Firewalls and create IP Blacklists for the network.
