Overview
The Information Security Early Warning Partnership is operated, in accordance with the public notice, as a framework for ensuring the proper distribution of vulnerability-related information concerning software and other products in Japan. Signatories such as IPA develop guidelines in cooperation with relevant parties and industries, while the study group examines vulnerability countermeasures and issues with the framework and incorporates its findings into revisions.
Impact
The framework aims to curb harm caused by computer viruses, unauthorized access, and other threats through the proper distribution of vulnerability-related information.
Details
The guideline summarizes recommended actions for discoverers, IPA and JPCERT/CC, product developers, and website operators. Discoverers are expected to follow the guidance when submitting a report, while product developers and website operators are expected to do so when notified. In addition to the main guideline, a Japanese and English summary edition and separate volumes for product developers, website construction businesses, website operators, and security staff have been published.
The 2026 revision added NICT as a signatory. It also states that when a discoverer reports to NICT and NICT advises or provides information to a product developer under the NICT Act, NICT and JPCERT/CC will coordinate closely to reduce the burden. The revision also added a provision for sharing with IPA vulnerabilities reported directly to JPCERT/CC. In addition, it introduced a new appendix explaining IPA's notification to the Cabinet Office under the Cyber Response Capability Enhancement Act and related laws, as well as the Cabinet Office's actions after notification.
