CEO of Southeast Asia’s largest bank names the 'new war' keeping her up at night

Context:

DBS CEO Tan Su Shan says cyber threats now constitute the biggest risk, framing cybersecurity as a perpetual, evolving war that could hinge on how attackers target AI-enabled systems. The bank adopts relentless red-teaming and a culture of deliberate paranoia to anticipate vulnerabilities before exploitation, with guardrails around AI interacting with core banking. As AI expands productivity yet widens the attack surface, DBS emphasizes strict data lifecycle management and transparent access controls to safeguard customer and core infrastructure. The broader environment remains volatile due to supply chains, geopolitics, and conflicts, underscoring the need for resilient, redundant playbooks. The path forward centers on smart, safe AI adoption and continuous preparedness to weather shocks.

Dive Deeper:

  • Tan emphasizes cyber security as the new war, noting that the most pressing risk comes from who might attack and how it could affect people.

  • DBS employs continuous red teaming and a culture of deliberate paranoia to stress-test systems and uncover vulnerabilities before attackers do.

  • Generative and agentic AI increase productivity but also expand the attack surface, especially when deployed in customer-facing or core banking systems, necessitating strong guardrails.

  • Data lifecycle management is prioritized, with strict governance over data creation, access, auditability, and transparency to protect sensitive information.

  • The operating environment is increasingly volatile due to supply chain disruptions, trade tensions, and geopolitical shocks, prompting broader resilience investments across processes like payments and ecosystems.

  • Tan argues that the differentiator for winners will be smart, safe adoption of AI and robust cybersecurity practices, including contingency planning and playbooks for worst-case scenarios.
