malware detection

Malware detection is a systematic process and set of technologies designed to identify, analyze, and flag malicious software within computer systems or networks. Its core concept, as outlined in NIST SP 800-83 (Guide to Malware Incident Prevention and Handling), involves multiple techniques such as signature-based scanning, behavioral analysis, and heuristic analysis. Within an Information Security Management System (ISMS) compliant with ISO/IEC 27001:2022, malware detection is a fundamental practice under control A.8.7 (Protection against malware). It serves as a critical component of operational risk management by providing the initial trigger for incident response procedures (defined in ISO/IEC 27035), helping to contain threats before they cause significant damage to data confidentiality, integrity, or availability. It is distinct from antivirus, which is a tool, and threat intelligence, which provides the data to enhance detection accuracy.

In enterprise risk management, malware detection is applied to translate cybersecurity threats into manageable operational risks. Implementation involves three key steps. First, conduct a risk assessment based on ISO/IEC 27005 to identify critical assets and define detection policies and metrics, such as Mean Time to Detect (MTTD). Second, deploy a defense-in-depth strategy using layered technologies like Endpoint Detection and Response (EDR), Network Detection and Response (NDR), and email sandboxing, aligned with the NIST Cybersecurity Framework's 'Detect' function. For example, a global manufacturing firm reduced malware-related downtime by 60% after deploying EDR. Third, integrate all detection alerts into a Security Information and Event Management (SIEM) platform for centralized monitoring and correlation, and connect it to a Security Orchestration, Automation, and Response (SOAR) tool to automate initial containment actions, ensuring rapid response and compliance with regulations like GDPR's breach notification requirements.

Taiwan enterprises face three primary challenges. First, limited resources, especially for SMEs, which often lack the budget and skilled personnel for advanced detection tools. The solution is to adopt Managed Detection and Response (MDR) services, which provide 24/7 expert monitoring on a subscription basis. Second, complex regulatory compliance, with industries like finance and healthcare facing specific local laws on top of the Personal Data Protection Act. The mitigation strategy is to implement a unified control framework mapping ISO 27001 controls to local requirements and deploying tools with robust logging for audits. Third, defending against Advanced Persistent Threats (APTs) that evade traditional signature-based methods. To counter this, enterprises should invest in behavior-based analytics, machine learning-driven EDR solutions, and establish proactive threat hunting programs to uncover hidden threats.
