Cyber threats continue to evolve, changing their attack patterns and development structures, making it harder to detect and enact proper mitigation procedures in time. Today, weapon systems are more software dependent and networked. Embedded software and IT systems enable operational success; however, they create new and extensive vulnerabilities that must be addressed properly. With the emergence of the Internet of Things (IoT), cloud computing, and higher connectivity, the avenues of attack and the likelihood of a breach are increasing. As a result, cybersecurity is more critical than ever because of the potential consequences of breaches in a distributed environment, and military-dedicated networks require better protection, especially for legacy components.
