The United States military is heavily dependent on networked communication to fulfill its missions. The wide-area network (WAN) infrastructure that supports this communication is vulnerable to a wide range of failures and cyber attacks that can severely impair connectivity and mission effectiveness at critical junctures. Examples include inadvertent or malicious misconfiguration of network devices, hardware and software failures, extended delays in Internet Protocol (IP) route convergence, denial of service (DoS) flooding attacks, and a variety of control-plane and data-plane attacks resulting from malicious code embedded within network devices.
Malicious actors in cyberspace currently operate with little fear of being caught due to the fact that it is extremely difficult, in some cases perhaps even impossible, to reliably and confidently attribute actions in cyberspace to individuals. The reason cyber attribution is difficult stems at least in part from a lack of end-to-end accountability in the current Internet infrastructure.
The threat of distributed denial of service (DDoS) attacks has been well-recognized in the data networking world for two decades. Such attacks are orchestrated by sets of networked hosts that collectively act to disrupt or deny access to information, communications or computing capabilities, generally by exhausting critical resources such as bandwidth, processor capacity or memory of targeted resources.
Malicious actors are currently able to compromise and use with impunity large numbers of devices owned and operated by third parties. Such collections of compromised and conscripted devices, commonly referred to as botnets, are used for criminal, espionage, and computer network attack purposes (often a combination of all three). Recent examples of botnets and similar malicious code include Mirai, Hidden Cobra, WannaCry, and Petya/NotPetya
Embedded systems form a ubiquitous, networked, computing substrate that underlies much of modern technological society. Such systems range from large supervisory control and data acquisition (SCADA) systems that manage physical infrastructure to medical devices such as pacemakers and insulin pumps, to computer peripherals such as printers and routers, to communication devices such as cell phones and radios, to vehicles such as airplanes and satellites. Such devices have been networked for a variety of reasons, including the ability to conveniently access diagnostic information, perform software updates, provide innovative features, lower costs, and improve ease of use.
