Product Security Incident Response Team

Product Security Incident Response Team (PSIRT) is a specialized group responsible for managing product-related security threats and vulnerabilities. Its origin lies in software security but has expanded with the rise of IoT, automotive cybersecurity (e.g UNECOTP) and industrial control systems. PSIRT handles threat intelligence, vulnerability assessment, and remediation strategies. According to ISO/IEC 29147:2018, PSIRT must follow standardized processes for vulnerability handling. Unlike a traditional IT SOC, PSIRT focuses on the entire product lifecycle—from design to end-of-life—ensuring the security and integrity of deployed devices. For companies subject to GDPR or Taiwan's Personal Data Protection Act, PSIRT's efficiency directly impacts legal liability and reputation management.

PSIRT application involves three stages: Intelligence Integration, Incident Response, and Communication. In the first stage, companies use a Common Platform Enumeration (CPE)-based asset-to-vulnerability mapping to automate threat identification. The second stage involves the technical response—developing, testing, and deploying patches or firmware updates. The third stage is the communication of these findings through Product Security Advisories. For example, a Taiwanese automotive supplier implementing a PSIRT could reduce the time-to-remediation for critical vulnerabilities by 70%, significantly lowering the risk of product-related breaches and ensuring compliance with international standards like ISO/SAE 21434.

Taiwan enterprises typically face three challenges: cross-departmental silos, technical resource constraints, and regulatory uncertainty. To overcome these, companies should first establish a clear PSIRT Charter endorsed by senior management to ensure cross-functional cooperation. Second, investing in automated vulnerability management tools can mitigate the shortage of specialized talent. Third, companies must map their PSIRT processes against international standards like ISO/IEC 29147 and local regulations to ensure legal compliance. A phased approach—starting with policy-making, followed by process-building, and ending with staff training—is recommended for successful implementation within 90 days.
