Session 1:　Active Cyber Defense

Active Cyber Defense (ACD): Public-Private Cooperation and the Strategic Role of the Military

With Japan’s formal decision to implement Active Cyber Defense (ACD), the nation’s cyber response framework has entered a new phase.
Ensuring its effectiveness requires a well-defined division of responsibilities and a coordinated framework between the public and private sectors.
In particular, the military is expected to engage from a national security perspective—technologically, institutionally, and operationally.
This session will explore effective models of public-private collaboration, with a focus on the role of the military in the implementation of ACD.

Session 2:　Cognitive Warfare

Defense in Narratives

The role of narratives in security has grown rapidly in recent years.
This shift stems from changes in the information environment and the ways people interact with and interpret information.
Narratives are difficult to separate from political and cultural contexts; however, when addressed as a cyber-related issue, it is essential to first examine the technical and engineering aspects involved.
This session will explore practical approaches to safeguarding the security value of narratives, particularly in relation to political and cultural activities.

Session 3:　Critical Infrastructure Protection

Ensuring the Protection and Resilience of Critical Infrastructure

Critical infrastructure spans a variety of sectors, including information and communications, finance, transportation, and energy. Organizations operating within these sectors often face a difficult dilemma: even when there is a suspected malware-related incident, the potential impact of shutting down systems is so significant that immediate investigation and response may not be feasible.
Furthermore, when the domestic supply chain is insufficient to meet all needs, there is often no choice but to rely on foreign-made products in critical infrastructure, introducing additional security risks.
This session will explore how we should approach the protection of critical infrastructure and what measures are essential to ensure its resilience and security.

Session 4: Space & Electromagnetic Warfare

Reimagining Space as the Next Theater of Operations

In recent years, the importance of security in the space domain has been increasingly recognized. Many systems that support critical infrastructure rely on signals from Global Navigation Satellite Systems (GNSS), which are vulnerable to threats from adversarial “killer satellites.” Additionally, long-range drones used in conflicts such as the war in Ukraine have relied on GNSS-based navigation, and there have been cases where spoofed GNSS signals have disrupted the operation of civilian aircraft.
Furthermore, some foreign governments are preparing to use commercial communication satellites as backups in the event of submarine cable outages during emergencies. However, the use of such privately owned satellites raises concerns for national security—particularly when access can be influenced by the decisions of a single major shareholder.
As the security of space and the electromagnetic spectrum becomes an increasingly critical issue, this session will explore what measures are needed and how best to approach security in these emerging domains.

Session 5: Emerging Disruptive Technology

Cybersecurity in the Quantum Era

The risk of quantum computers breaking encryption will not wait 20 years for the practical quantum computers. The potential for harvest attacks to emerge as a genuine threat is a pressing concern that demands urgent attention. Post Quantum Cryptography (PQC) has been intensively studied for years, but there remain challenges to be addressed. Quantum key distribution networks (QKDN), including satellite quantum communication, will offer a solution for secure global-scale information infrastructure. The social deployment of QKDN allows us to simultaneously guarantee long-term security and low-latency communication. Coexistence of QKDN and PQC will facilitate the development of systems that leverage the strengths of both technologies. This session will discuss practical approaches to building a secure information infrastructure for the quantum era that integrates QKDN and PQC.

Session 6: Education

Cyber Education Through the Lens of National Security

Cyber threats encompass not only technical attacks but also cognitive and psychological manipulation.
In particular, influence operations conducted via social media by authoritarian regimes pose a serious challenge to the foundations of democratic societies.
This session explores how cyber education can contribute to safeguarding citizens against such threats through targeted educational initiatives and strategic awareness programs.
