ISO/IEC 30111:2019

Overview

ISO/IEC 30111:2019 - Information technology - Security techniques - Vulnerability handling processes - defines requirements and recommendations for how vendors should process, investigate and remediate reported potential vulnerabilities in products and services. Intended for vendors, developers, evaluators and users, the standard prescribes a documented, repeatable vulnerability handling process and organizational framework to ensure timely, secure and accountable remediation.

Key topics and requirements

• Vulnerability handling lifecycle: Defines phases vendors should implement, including preparation, receipt, verification, remediation development, release, and post-release monitoring and follow-up.
• Policy and leadership: Requires top-management commitment, a documented internal vulnerability handling policy, objectives aligned with organizational strategy, and assignment of roles, responsibilities and authorities.
• Organizational structure: Recommends establishing or coordinating a PSIRT (Product Security Incident Response Team) or CSIRT capability, defining mission, responsibilities and staff capabilities.
• Confidentiality and disclosure controls: Emphasizes safeguards to prevent premature disclosure of vulnerability information and coordination with external disclosure policies.
• Process monitoring and improvement: Calls for periodic assessment, performance reporting to management, and continual improvement of the vulnerability handling process.
• Supply chain considerations: Addresses the need to consider ICT supply chain security when investigating and remediating vulnerabilities.
• Documentation and traceability: Vendors should document procedures and methods to track all reported vulnerabilities and remediation actions.

Practical applications & who uses it

• Software and hardware vendors use ISO/IEC 30111:2019 to build or improve their vulnerability handling processes (PSIRT/CSIRT), ensuring consistent triage, root-cause analysis and remediation workflows.
• Security teams and developers follow the standard to integrate vulnerability remediation with secure development lifecycles and application security practices.
• Evaluators and auditors use the standard to assess a vendor’s vulnerability handling maturity and conformance.
• Procurement and security-conscious buyers reference its requirements to set vendor expectations and contract clauses for product security and disclosure practices.
• Legal, customer support and PR teams leverage the recommended organizational roles to coordinate communications and legal risk management during vulnerability incidents.

Related standards

• ISO/IEC 29147 (Vulnerability disclosure) - meant to be used in conjunction with ISO/IEC 30111 for external reporting and remediation information distribution.
• ISO/IEC 27034 (Application security) and ISO/IEC 27036‑3 (ICT supply chain security) - provide complementary guidance on secure development and supply chain considerations.
• ISO/IEC 15408-3 - referenced for relevant assurance considerations.
