U.S. Cyber Policy: A Call for Offensive Posture

Introduction

U.S. lawmakers are increasingly pressing for a robust offensive cyber posture as they consider the implications of adversarial actions in the digital domain. The recent confirmation hearing for Katie Sutton, the nominee for Assistant Secretary of Defense for Cyber Policy, highlighted the prevailing concern among senators regarding the current defensive stance of the U.S. in cyberspace and the need for a more proactive approach.

Concerns About Deterrence Strategy

During the hearing, Senator Tom Cotton (R-Ark.) underscored that a solely defensive posture may be insufficient to deter threats from major adversaries, including China, Russia, Iran, and North Korea. He posed critical questions about whether the U.S. has sufficiently invested in offensive cyber strategies that could target the core interests of these nations.

Senator Angus King (I-Maine) echoed this sentiment, emphasizing the need for a clearly articulated doctrine of cyber deterrence similar to that of nuclear deterrence. He expressed frustration over the perceived lack of a cohesive strategy, reminding that adversaries do not hold fear of U.S. capabilities in cyberspace.

Key points from their discussion include:

• Defense Alone Is Insufficient: The notion that a defensive stance will protect the U.S. is increasingly seen as flawed.
• Need for Policy Clarity: Without a clear doctrine, adversaries may underestimate or disregard the consequences of their cyber actions.

Sutton’s Vision for Cyber Policy

In her responses, Sutton committed to improving U.S. cyber capabilities and articulating these strategies clearly. She noted:

• Emphasis on Offensive Capabilities: Highlighting that defenses may fail, Sutton stated that a robust offensive component is essential for national security.
• Alignment of Strategies: If confirmed, she plans to integrate military cyber capabilities with broader national power tools to present a united front against cyber threats.

Currently, the Defense Department (DoD) is focusing on enhancing both offensive and defensive strategies to effectively deter adversaries. Sutton’s approach aligns with the administration’s objective to closely monitor and counteract Chinese incursions into critical U.S. infrastructure, signaling a shift toward an offensive operational stance.

The Need for a Cultural Shift

Sutton also underscored the necessity for a cultural transformation within the U.S. cyber community. She pointed out that, historically, discussion of offensive cyber operations has been limited. However, she argued that openly discussing these capabilities could enhance public understanding and support.

• Transparency in Offensive Operations: Unlike traditional military operations, which tend to be publicly discussed, cyber operations remain shrouded in secrecy. There is a potential misconception among the public that the U.S. is only on the defensive, which could undermine confidence in national security.

Reevaluating Cyber Authorities

Sutton highlighted the need to revisit existing authorities that govern cyber operations. Following recent intrusions and adversarial malign activities, there is consensus that the U.S. must adapt to the evolving cyber landscape. Key considerations include:

• Agility in Response: As cyber threats evolve rapidly, Sutton advocated for re-examining current policies and authorities to ensure readiness against diverse forms of attacks, including those linked to artificial intelligence.
• Operational Flexibility: Sutton emphasized the necessity of maintaining operational flexibility while conducting persistent engagement to counter threats early in their development.

Enhancing Deterrence in Cyberspace

The contemporary security landscape necessitates the U.S. to rethink its deterrent strategies. Sutton articulated her commitment to establishing a credible deterrent against cyber aggressors through:

• Denial and Resilience: Implementing systems that can withstand and recover from attacks, thereby signaling to adversaries that success is uncertain.
• Credible Response Mechanisms: Ensuring that responses to cyber offenses are not only substantial but also communicated effectively to adversaries.

Conclusion

As the U.S. navigates the challenges of cyber warfare, the balancing act between defense and offense will be crucial. Senators and defense leaders recognize the importance of a well-rounded strategy that includes both resilience and proactive measures. Sutton’s potential leadership could represent a pivotal moment for U.S. cyber policy, aligning resources and strategies to better deter adversarial actions while reassuring the public of their safety in the digital realm.

In summary, the future of U.S. cyber strategy hinges on an urgent transformation towards an assertive posture—one that effectively communicates the nation’s capabilities and intentions not merely as defenders but as formidable players on the global cyber stage.
