IriusRisk has launched a new Open Threat Model (OTM) standard to allow greater connectivity and interoperability between threat modeling and other parts of the software development lifecycle (SDLC). The OTM standard has been published under a Creative Commons license and provides a tool-agnostic way of describing a threat model in a simple to use and understand format, IriusRisk said.The standard can leverage a wide range of source formats and supports new sources of application and system design, whilst also allowing users to exchange threat model data within the SDLC and cybersecurity ecosystem. An accompanying API allows users to provide an OTM file which IriusRisk uses to build a full threat model using the rules engine, which contains an extensive library of components and risk patterns.Standard designed to secure SDLCs, simplify threat modelingThe OTM standard is part of the 4.1 release of the IriusRisk product and designed for software architects, DevOps and DevSecOps personnel that are working towards secure design and want to contribute to the adoption of threat modeling as an industry standard, IriusRisk explained in a posting on its website. It presents threat models in a common format allowing users to utilize data through integrations and works with different source formats including Amazon Web Services Cloudformation.Users can also write and share parsers for artefacts such as CloudFormation, Visio or Docker Compose files. \u201cIn addition, OTM facilitates exchanges between organizations,\u201d IriusRisk added. \u201cAs it has been launched under Creative Commons, the standard can be used in open-source projects or even by commercial vendors to share threat models of their systems, in order for those in turn to be used by organizations adopting those systems.\u201dCommenting in a press release, Stephen De Vries, IriusRisk CEO and founder, said: \u201cWith the launch of our Open Threat Model standard, we are building a tool that will transform the threat modeling process. With the wider security and developer community contributing to the Standard, we are excited to see the combined impact we can have on secure design by making threat modeling an increasingly simple and widely adopted practice.\u201dOTM standard could address software development security incohesionThe standard comes at a time when the security implications surrounding SDLCs are significantly impacting organizations. Last year, a report from Osterman Research outlined considerable incohesion between software development teams and cybersecurity functions compounding the software supply chain risks faced by businesses. It revealed that 45% of development teams felt their understanding of the latest application attacks is lacking, with the vast majority admitting to knowingly pushing vulnerable code live.What\u2019s more, just 27% of frontline development professionals considered application security their responsibility, while only half of CISOs were confident that secure applications can be developed and 45% of security workers felt developers did not understand the latest threats to application security.Speaking to CSO, cybersecurity consultant Harman Singh says that the OTM standard is significant for businesses because it provides a framework for threat modelling that can be used by teams and organizations of all sizes at different stages of the SDLC. \u201cThe OTM standard has been designed to be easy to use and understand so that businesses can quickly and effectively assess the risks to their systems. The OTM standard is also flexible, so businesses can adapt it to meet their specific needs,\u201d he adds.The benefits of using the standard include the ability to quickly and effectively assess the risks to systems, the flexibility to adapt it to meet specific needs, and the capability to prioritize risks and design relevant controls, Singh says.
