Is this all you need to implement DevSecOps? No, but it will have a great impact on the software development culture. More importantly, it helps the team members build an understanding of each other’s roles, objectives and pain points. In other words, threat modeling, by its very nature, fosters a culture of communication and collaboration. A living document known as a threat model includes inputs from the whole team. When you are threat modeling, you bring the security architect, the operations/infrastructure team and lead developers together. DevOps is the idea that the operations team and development team should be one unit, share skill sets and establish a common goal.
Sorry, but DevOps is neither a tool nor a process nor a combination of both. One of my biggest pet peeves is hearing an organization’s upper leadership say they have implemented DevOps processes through tooling and moved the operations team right next to the development team. Threat modeling can be a great way to start building a DevSecOps culture. By continuously threat modeling applications, security teams can better protect apps while educating the development team and building a culture of security throughout the enterprise. Threat modeling is the practice of identifying and prioritizing potential threats and security mitigations to protect something of value, such as confidential data or intellectual property.
SOFTWARE THREAT MODELING CODE
Threat modeling is an easy and cost-effective way to implement security in the design phase of the SDLC, before any code ever gets written. This leads to more critical vulnerabilities in production, an increased risk to the business and remediation costs exponentially greater than those of implementing security by design in the early stages of the software development life cycle (SDLC). As such, it is given less priority or totally ignored for the sake of hitting production deadlines. Security in application development is often an afterthought and seen as an impediment to developers. Throughout my career in software development and application security, I have worked on many development and operations teams and have often seen issues when it comes to implementing security into applications and products.
