Why Critical Infrastructure Cybersecurity Must Become Forensic-Ready

In the evolving landscape of cyber threats, a significant challenge facing critical infrastructure organizations is the "cybersecurity accountability gap." This gap arises because traditional incident response often focuses on containing a breach as quickly as possible, a necessary step that can unfortunately lead to the destruction of crucial forensic evidence. Without this evidence, it becomes exceedingly difficult to determine who was responsible for an attack, pursue legal action, or even learn effectively from the incident to prevent future occurrences. The article introduces the concept of "forensic readiness" as a vital proactive measure. Unlike reactive digital forensics, which begins after an incident, forensic readiness involves establishing the capability to anticipate, preserve, and produce digital evidence in a way that stands up to legal, regulatory, and operational scrutiny, all without disrupting ongoing business operations. This forward-thinking approach ensures that organizations are prepared to collect and maintain the integrity of evidence from the outset. The author identifies three common failure modes in current cybersecurity practices: the "visibility trap," where detection tools fire but underlying volatile evidence is not preserved; the "attribution void," where attacks are logged but the 'who, why, and what' of the incident remain unknown; and the "consequence gap," where the chain of custody for evidence breaks, preventing accountability. These issues collectively undermine the ability to achieve meaningful outcomes from incident response. Ultimately, the piece stresses that cybersecurity must evolve beyond mere detection. The future of robust cybersecurity lies in ensuring that every significant attack leaves behind admissible evidence, actionable intelligence, and opportunities for institutional learning. By embracing forensic readiness, organizations can move towards a more defensible and accountable cyber resilience posture, especially as cyber threats become more sophisticated and AI accelerates the operational tempo of attacks.
