Cyberwarfare in the United States


As a major developed economy, the United States is highly dependent on the Internet and therefore greatly exposed to cyber attacks. At the same time, the United States has substantial capabilities in both defense and power projection thanks to comparatively advanced technology and a large military budget. Cyber warfare presents a growing threat to physical systems and infrastructures that are linked to the internet. Malicious hacking from domestic or foreign enemies remains a constant threat to the United States. In response to these growing threats, the United States has developed significant cyber capabilities.
The United States Department of Defense recognizes the use of computers and the Internet to conduct warfare in cyberspace as a threat to national security, but also as a platform for attack.
The United States Cyber Command centralizes command of cyberspace operations, organizes existing cyber resources and synchronizes defense of U.S. military networks. It is an armed forces Unified Combatant Command.

The Department of Defense Cyber Strategy

In April 2015, the U.S. Department of Defense published its latest Cyber Strategy building upon the previous DoD Strategy for Operating in Cyberspace published in July 2011. The DoD Cyber strategy focuses on building capabilities to protect, secure, and defend its own DoD networks, systems and information; defend the nation against cyber attacks; and support contingency plans. This includes being prepared to operate and continue to carry out missions in environments impacted by cyber attacks.
The DoD outlines three cyber missions:
  1. Defend DoD networks, systems, and information.
  2. Defend the United States and its interests against cyber attacks of significant consequence.
  3. Provide integrated cyber capabilities to support military operations and contingency plans.
In addition, the Cyber Strategy emphasizes the need to build bridges to the private sector, so that the best talent and technology the United States has to offer is at disposal to the DoD.

The Five Pillars

The five pillars is the base of the Department of Defense's strategy for cyber warfare. The first pillar is to recognize that the new domain for warfare is cyberspace and that it is similar to the other elements in the battlespace. The key objectives of this pillar are to build up technical capabilities and accelerate research and development to provide the United States with a technological advantage. The second pillar is proactive defenses as opposed to passive defense. Two examples of passive defense are computer hygiene and firewalls. The balance of the attacks requires active defense using sensors to provide a rapid response to detect and stop a cyber attack on a computer network. This would provide military tactics to backtrace, hunt down and attack an enemy intruder. The third pillar is critical infrastructure protection to ensure the protection of critical infrastructure by developing warning systems to anticipate threats. The fourth pillar is the use of collective defense which would provide the ability of early detection, and incorporate it into the cyber warfare defense structure. The goal of this pillar is to explore all options in the face of a conflict, and to minimize loss of life and destruction of property. The fifth pillar is building and maintaining international alliances and partnerships to deter shared threats, and to remain adaptive and flexible to build new alliances as required. This is focused on "priority regions, to include the Middle East, Asia-Pacific, and Europe".

Trump Administration's National Cyber Strategy

Shortly after his election, U.S. President Donald Trump pledged to deliver an extensive plan to improve U.S. cybersecurity within 90 days of his inauguration. Three weeks after the designated 90-day mark, he signed an executive order that claimed to strengthen government networks. By the new executive order, federal-agency leaders are to be held responsible for breaches on their networks and federal agencies are to follow the National Institute of Standards and Technology Framework for Improving Critical Infrastructure Cybersecurity in consolidating risk management practices. In addition, the federal departments were to examine cyber defense abilities of agencies within 90 days, focusing on "risk mitigation and acceptance choices" and evaluating needs for funding and sharing technology across departments. Experts in cybersecurity later claimed that the order was "not likely" to have a major impact.
In September, President Trump signed the National Cyber Strategy- "the first fully articulated cyber strategy for the United States since 2003." John Bolton, the National Security Advisor, claimed in September 2018 that the Trump administration's new "National Cyber Strategy" has replaced restrictions on the use of offensive cyber operations with a legal regime that enables the Defense Department and other relevant agencies to operate with a greater authority to penetrate foreign networks to deter hacks on U.S. systems. Describing the new strategy as an endeavor to "create powerful deterrence structures that persuade the adversary not to strike in the first place," Bolton added that decision-making for launching attacks will be moved down the chain of command from requiring the president's approval.
The Defense Department, in its strategy document released in September 2018, further announced that it would "defend forward" U.S. networks by disrupting "malicious cyber activity at its source" and endeavor to "ensure there are consequences for irresponsible cyber behavior" by "preserving peace through strength."
The National Cyber Strategy has also garnered criticisms that evaluating acts of cyberwarfare against the United States still remains ambiguous, as the current U.S. law does not specifically define what constitutes an illegal cyberact that transcends a justifiable computer activity. The legal status of most information security research in the United States is governed by 1986 Computer Fraud and Abuse Act, which was derided to be "poorly drafted and arbitrarily enforced" by enabling prosecution of useful information security research methods such as Nmap or Shodan. As even the needed services fall into prohibition, top-level information security experts find it challenging to improve the infrastructure of cyberdefense.

Cyberattack as an act of war

In 2011, The White House published an "International Strategy for Cyberspace" that reserved the right to use military force in response to a cyberattack:
In 2013, the Defense Science Board, an independent advisory committee to the U.S. Secretary of Defense, went further, stating that "The cyber threat is serious, with potential consequences similar in some ways to the nuclear threat of the Cold War," and recommending, in response to the "most extreme case", that "Nuclear weapons would remain the ultimate response and anchor the deterrence ladder."

Attacks on other nations

Iran

In June 2010, Iran was the victim of a cyber attack when its nuclear facility in Natanz was infiltrated by the cyber-worm 'Stuxnet', said to be the most advanced piece of malware ever discovered and significantly increases the profile of cyberwarfare. It destroyed perhaps over 1,000 nuclear centrifuges and, according to a Business Insider article, " Tehran's atomic program back by at least two years."
Despite a lack of official confirmation, Gary Samore, White House Coordinator for Arms Control and Weapons of Mass Destruction, made a public statement, in which he said, "we're glad they are having trouble with their centrifuge machine and that we—the US and its allies—are doing everything we can to make sure that we complicate matters for them", offering "winking acknowledgement" of US involvement in Stuxnet.

China

In 2013, Edward Snowden, a former systems administrator for the Central Intelligence Agency and a counterintelligence trainer at the Defense Intelligence Agency, revealed that the United States government had hacked into Chinese mobile phone companies to collect text messages and had spied on Tsinghua University, one of China's biggest research institutions, as well as home to one of China's six major backbone networks, the China Education and Research Network, from where internet data from millions of Chinese citizens could be mined. He said U.S. spy agencies have been watching China and Hong Kong for years.
According to classified documents provided by Edward Snowden, the National Security Agency has also infiltrated the servers in the headquarters of Huawei, China's largest telecommunications company and the largest telecommunications equipment maker in the world. The plan is to exploit Huawei's technology so that when the company sold equipment to other countries—including both allies and nations that avoid buying American products—the NSA could roam through their computer and telephone networks to conduct surveillance and, if ordered by the president, offensive cyberoperations.

Russia

In June 2019, Russia has conceded that it is "possible" its electrical grid is under cyber-attack by the United States. The New York Times reported that American hackers from the United States Cyber Command planted malware potentially capable of disrupting the Russian electrical grid.

Others

The Pentagon has had an information sharing arrangement, the Defense Industrial Base Cybersecurity and Information Assurance program, in place with some private defense contractors since 2007 to which access was widened in 2012.
A number of other information sharing initiatives such as the Cyber Intelligence Sharing and Protection Act and Cybersecurity Information Sharing Act have been proposed, but failed for various reasons including fears that they could be used to spy on the general public.
