Siemens is committed to help ensuring the safety and security of their customers’ facilities. Siemens follows a holistic and comprehensive approach to secure its products, solutions, services, and IT infrastructure. Siemens has formalized a process for handling reported security vulnerabilities in its product portfolio and IT infrastructure.
Siemens is prepared to work in good faith with individuals that submit vulnerability reports through ways described in section “Contact Information”. Siemens openly accept reports for currently listed Siemens products, solutions, and Siemens IT infrastructure. Siemens does not intend to engage in legal action against individuals who:
The vulnerability handling process consists of the following four steps at Siemens:
To report a security vulnerability affecting a Siemens product, solution or infrastructure component, please contact Siemens using the ways described in section “Contact Information”. Siemens usually responds to incoming reports within one business day (reference: Munich, Germany).
Please report the following information:
Everyone is encouraged to report discovered vulnerabilities, regardless of service contracts or product lifecycle status. Siemens welcomes vulnerability reports from researchers, industry groups, CERTs, partners and any other source as Siemens does not require a nondisclosure-agreement as a prerequisite for receiving reports. Siemens respects the interests of the reporting party (also anonymous reports if requested) and agrees to handle any vulnerability that is reasonably believed to be related to Siemens products, solutions or infrastructure components. Siemens urges reporting parties to perform a coordinated disclosure, as immediate public disclosure causes a ‘0-day situation’ which puts Siemens’ customer systems at unnecessary risk. Those systems comprise significant parts of the worldwide critical infrastructure.
Siemens investigates and reproduces the vulnerability. If needed, Siemens will request more information from the reporter.
Siemens performs internal vulnerability handling in collaboration with the responsible development groups. National and Governmental CERTs having a partnership with Siemens ProductCERT may be notified about a security issue in advance. During this time, regular communication is maintained between Siemens and the reporting party to inform about the current status and to ensure that the vendor’s position is understood by the reporting party. If available, pre-releases of software fixes may be provided to the reporting party for verification.
After the issue was successfully analyzed and if a fix is necessary to cope with the vulnerability, corresponding fixes will be developed and prepared for distribution. Siemens will use existing customer notification processes to manage the release of patches, which may include direct customer notification, or public release of a security advisory containing all necessary information on the Siemens CERT Services website (see section “Contact Information”).
