Due to safety concerns and legislation implemented by various governments, the maritime sector adopted Automatic Identification System (AIS). Whilst governments and state agencies have an increasing reliance on AIS data, the underlying technology can be found to be fundamentally insecure. This study identifies and describes a number of potential attack vectors and suggests conceptual countermeasures to mitigate such attacks. With interception by Navy and Coast Guard as well as marine navigation and obstacle avoidance, the vulnerabilities within AIS call into question the multiple deployed overlapping AIS networks, and what the future holds for the protocol.

The Industrial Internet of Things (IIoT) is a term applied to the industrial application of M2M devices. The security of IIoT devices is a difficult problem and where the automation of critical infrastructure is intended, risks may be unacceptable. Remote attacks are a significant threat and solutions are sought which are secure by default. The problem space may be analyzed using threat modelling methods. Software Defined Networks (SDN) provide mitigation for remote attacks which exploit local area networks. Similar concepts applied to the WAN may improve availability and performance and provide granular data on link characteristics. Schemes such as the Software Defined Perimeter allow IIoT devices to communicate on the Internet, mitigating avenues of remote attack. Finally, separation of duties at the IIoT device may prevent attacks on the integrity of the device or the confidentiality and integrity of its communications. Work remains to be done on the mitigation of DDoS.
