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.
The Department of Defense’s information technology (IT) infrastructure is made up of a large, complex network of connected local networks comprised of thousands of devices. Cyber defenders must understand and monitor the entire environment to defend it effectively. Toward this end, cyber-defenders work to correlate and understand the information contained in log files, executable files, databases of varying formats, directory structures, communication paths, file and message headers, as well as in the volatile and non-volatile memory of the devices on the network. Meanwhile, adversaries increasingly use targeted attacks that disguise attacks as legitimate actions, making discovery far more difficult. It is within this complicated web of networked systems that cyber defenders must find targeted cyber-attacks.
A substantial and prolonged disruption of electric power would have profound economic and human costs for the United States. From a defense perspective, a major power outage could hamper military mobilization and logistics and impair the capability to project force.
