Defensive Cyberspace Operation Response Action (DCO-RA) is a military term referring to the action taken by Department of Defense networks to thwart a confirmed cyber attack. The aim of DCO-RA is to secure, safeguard, and defend their own cyberspace resources while maintaining their essential functions. It might include measures like hunting for malicious activity, isolating harmful incidents, or conducting resilience measures to restore affected capabilities.

Key Takeaways

  1. Defensive cyberspace operation response action (DCO-RA) represents the military’s efforts to protect its own cyber networks and systems. It involves taking any measures necessary to defend important information while denying adversaries access or influence over these cyber systems.
  2. DCO-RA not only includes reacting to cyber attacks but also includes preemptive actions to strengthen security. These actions could include software updates, installation of security patches, system monitoring, threat analysis, etc., which ensure the reinforcement of security measures before an attack happens.
  3. The DCO-RA extends beyond solely defensive actions, it can also allow, when authorized, to execute offensive procedures to neutralize or destroy threats, potentially even in systems not owned by the Department of Defense. Therefore, it plays a critical role in maintaining operational advantage and overall national security.

Importance

Defensive Cyberspace Operation Response Action (DCO-RA) plays a significant role in the realm of military operations as it operates as a crucial mechanism protecting, securing, and defending information in cyberspace from threats.

Given the rapid increase in cyber threats and the ever-evolving nature of cyber warfare, DCO-RA is increasingly important.

It involves the implementation of response actions that not only identify, analyze, and defend against cyber threats, but also actively seek to prevent potential threats.

This capability contributes heavily to national security and military readiness, ensuring the safety and integrity of confidential information in an increasingly interconnected world, filled with advanced persistent threats.

Thus, the essence of DCO-RA lies in its ability to bolster the resilience of military operations against cyber threats.

Explanation

Defensive Cyberspace Operation Response Action (DCO-RA) is a crucial facet of the United States military’s overall strategy to safeguard its cyberspace and deter, counter, and overcome adversarial cyber activities. The basic purpose of DCO-RA is to conduct military cyberspace operations in response to authorized retaliation against perceived threats.

In simpler terms, DCO-RA allows the military to take necessary actions to defend its cyber infrastructure against individuals, groups, or nation-states that might threaten its operational efficiency, national security, or critical resources. In terms of its usage, DCO-RA activities can range from detecting and analyzing intrusions in the military’s cyberspace, defining the extent of potential damage in case of a breach, and devising and implementing strategies to mitigate or even neutralize detected threats.

Moreover, these operations are designed in a way that they not only secure the military’s existing cyber domains but also seek out to obstruct adversaries who attempt to exploit the United States’ cyberspace. Overall, DCO-RA primarily serves as a protective shield and a retaliatory measure to ensure that the nation’s cyber infrastructure and proprietary information remain secure at all times.

Examples of Defensive cyberspace operation response action (DCO-RA)

Operation Glowing Symphony: This was a U.S. Cyber Command operation against ISIS (Islamic State of Iraq and Syria). The objective was to disrupt the group’s use of the internet for propaganda, recruitment, and command and control in

This was a DCO-RA because it aimed to defend against the online activities of ISIS by interrupting their ability to use it.

North Korean-Initiated Cyber Attacks: In response to continuous cyber attacks by North Korea, the U.S. military conducted DCO-RAs. Under Operation Plan 5027, the U.S. aimed to defend its critical infrastructures and neutralize North Korean cyber operations by disabling their command and control servers and key figures.

Response to Iranian Cyber Attacks: In 2019, the U.S. Cyber Command conducted DCO-RAs in response to Iranian cyber attacks on U.S. Naval assets. The operations aimed to neutralize and deter threat by eliminating key assets from the Iranian Cyber Command’s infrastructure, thus reducing their ability to conduct and coordinate attacks.
