Cyber Incidents

A cyber incident, as defined by NIST Special Publication 800-61 Rev. 2, is a violation or imminent threat of violation of computer security policies. The international standard ISO/IEC 27035 provides a framework for incident management. It is distinct from a "security event," which is any observable occurrence. An incident is a confirmed adverse event that compromises the confidentiality, integrity, or availability (CIA) of information assets. In enterprise risk management (ERM), cyber incidents are a critical operational risk with potential for significant financial and reputational damage. Regulations like GDPR mandate reporting within 72 hours, highlighting its regulatory importance.

In ERM, cyber incident management follows a structured lifecycle, often based on the NIST framework: 1. Preparation: Establishing a Computer Security Incident Response Team (CSIRT) and developing response plans. 2. Detection & Analysis: Using tools like SIEM to monitor for anomalies and determine an incident's scope. 3. Containment, Eradication & Recovery: Isolating affected systems, removing the threat, and restoring operations. A major Taiwanese financial company implemented this model, reducing its Mean Time to Detect (MTTD) by 60% and Mean Time to Respond (MTTR) by 75%, ensuring compliance with regulatory reporting deadlines and passing cybersecurity audits.

Taiwan enterprises face three key challenges: 1. Regulatory Pressure: Taiwan's Cyber Security Management Act imposes tight reporting deadlines (e.g., one hour), which are difficult to meet. 2. Talent Shortage: There is a lack of professionals skilled in digital forensics and threat hunting. 3. Resource Constraints: SMEs often lack the budget for dedicated security teams or advanced tools. To overcome these, companies should use pre-defined incident playbooks, engage Managed Detection and Response (MDR) services to bridge the talent gap, and adopt cloud-based Security-as-a-Service (SaaS) models to manage costs.
