As geopolitical tensions intensify across the Indo-Pacific, much of the public focus remains on naval movements and territorial disputes. Yet beneath these visible tensions lies an imminent threat in cyberspace—one capable of disrupting economies, crippling critical infrastructure, and eroding public trust without firing a single shot.
For the Philippines, an archipelagic nation whose security and prosperity depend on interconnected maritime and digital networks, strengthening cyber resilience must become a central priority as hybrid warfare increasingly shapes the region’s strategic landscape.
Speaking at the seminar “Indo-Pacific: Cyber Domain as the New Frontier of Security”, hosted by the Italian Embassy in Manila, Major General Angelito M. de Leon, Undersecretary for Defense Affairs of the Department of National Defense, warned that cybersecurity is no longer simply a technical issue—it has become a strategic imperative.
Cyber threats now span espionage, intellectual property theft, attacks on critical infrastructure, and hybrid operations targeting information systems, public trust, and economic stability.
“Cybersecurity is no longer simply a technical issue. It is a strategic imperative that directly affects national sovereignty, economic stability, and the integrity of our democratic institutions,” De Leon said.
He stressed that the Philippines must accelerate its shift from decades of internal security operations toward a broader external defense posture, particularly in protecting its maritime domain and critical digital infrastructure.
This includes submarine communication cables, which carry roughly 90 percent of global data traffic, supporting financial systems, communication networks, and international commerce.
Six critical pillars
1. Protect critical infrastructure – secure government networks, financial systems, energy grids, and transport networks from cyber disruptions.
2. Strengthen military cyber capabilities – expand the role of the AFP Cyber Command in defense operations and network protection.
3. Develop robust response systems – ensure rapid recovery and redundancy for government and industry networks in the event of attacks.
4. Invest in innovation and technology – leverage AI, quantum computing, and other emerging technologies, while supporting domestic production and research.
5. Enhance international cooperation – work with allies and regional partners to share intelligence, conduct joint exercises, and promote a rules-based order in cyberspace.
6. Safeguard public trust and institutions – counter disinformation, protect democratic processes, and strengthen cyber literacy.
De Leon noted that disruptions in cyberspace could affect maritime navigation systems, satellite communications, and command-and-control networks, especially in sensitive areas like the West Philippine Sea.
These hybrid threats—blending cyber attacks, disinformation, espionage, and conventional pressure—require a whole-of-nation approach combining government, the armed forces, industry, academe, and international partners.
“The cyber domain may be intangible, but its impact is very real. It influences the security of our nation, the prosperity of our economy, and the confidence of our citizens,” De Leon said.
“Our collective efforts today will shape the resilience and stability of the Indo-Pacific for generations to come,” he added.
