Traditionally, security has often been something ‘bolted on’ to applications, much like an additional layer of defense. What if, instead of retrofitting fortifications, we were to build the security into the foundation? Secure by design flips this script, ensuring that security is baked into the very fabric of an application throughout its life cycle. Threat Modeling becomes the cornerstone for this approach. By working through application flows, assets, and vulnerabilities systematically, we can identify where threats might emanate from and design control mechanisms to mitigate them upfront.
This proactive approach has a host of advantages associated with it. According to expert studies, threat modeling will reduce the number of vulnerabilities in applications substantially. Imagine the cost savings, brand protection, and peace of mind associated with the development of applications in which security is a core tenet.
Understanding Secure by Design
Secure by Design is the end-to-end process of infusing security into SDLC. That is making the application intrinsically secure by design. This approach involves the following:
- Comprehensive Risk Assessment: To identify all possible security risks at the outset.
- Proactive Mitigation Strategies: Develop countermeasures for all the identified risks.
- Continuous Security Integration: Security best practices should mature as an application does.
The Role of Threat Modeling in Secure by Design
Threat modeling is an organized attempt to find and mitigate security risks early during the design phase of software. It is an attempt to understand what kind of threats an application may face and what the level of criticality they have, along with forming strategies on how to deal with them. Threat modeling is at the core of any security initiative and rests as the base for the secure by design approach. It ensures that organizations can develop robust, secure applications right from the initial phase of design. ThreatModeler, with its industry-leading position, offers a comprehensive platform that simplifies the process by automating threat modeling to make it both accessible and efficient for development teams.
Identify Threats Early: Reduce Vulnerabilities, Enhance Security
One of the most compelling reasons for including threat modeling early in the development process is its influence on vulnerability management. If the potential threats are identified from the design stage, the peak potential of vulnerabilities at a later stage in the application’s software life cycle could be greatly reduced.
It allows for building security into the design before identifiable vulnerabilities are exploited. Early intervention helps in different ways:
- Proactive design adjustments: Developers can make some design-phase modifications that make good sense based on identified threats at the beginning of the process. This includes modifications that fix security gaps, but more easily, before they glide through the lifecycle of development and into production.
- Advanced Risk Management: Early identification of threats makes risk assessment better; that is, the likelihood and impacts of potential security breaches can be looked at more accurately for targeted and effective mitigation.
- Cost saving: The costs of fixing a vulnerable system post-development or after deployment are higher when compared to fixing the system at the stage of design. Early detection of a potential problem will ensure it is taken care of early enough, and this costs the organization a lot less than would be incurred over the whole budget of development.
- Reduced Time to Market: Building security thoughts into the lifecycle from the start streamlines development. Fewer bumps and hitches are removed while generated by last-minute security fixes, making time to market even faster.
- Increased Confidence: A well-designed application that seems to be conscious about the threats and neutralizes the same also helps in increasing the confidence about security among application users, developers, and other stakeholders as well.
Threat Modeling, Democratized
Threat modeling doesn’t have to be complicated. At ThreatModeler, we believe that anyone can harness its power. In our blog series, we have put together a plethora of resource materials to democratize threat modeling. In one of our articles, we really answer: “What is the one thing which can make your threat modeling easy?” The secret is not to be afraid to start by dragging and dropping together diagrams and code you already have.
Cloud Security and Beyond
The landscape of cloud applications introduces a new dimension to security considerations. Securing cloud environments has become a shared responsibility, as explained in our blog: How to Do Threat Modeling for Cloud Applications. In this context, threat modeling takes center stage. Our CloudModeler tool automates threat modeling for cloud deployments, creating an immense amount of efficiency in this process.
ThreatModeler in Practical Implementation
ThreatModeler provides a streamlined approach to integrating threat modeling into the secure by design framework:
- Automated Threat Identification: ThreatModeler’s platform automatically identifies potential threats, taking this burden off the developer.
- Dynamic Risk Assessment: Within the platform, risks are continuously assessed to ensure that security measures are kept up-to-date.
- Collaborative Environment: ThreatModeler allows collaboration between the Dev, Security, and Operations teams in a security strategy.
Creating Culture of Secure By Design
The shift to secure by design is cultural, not technological. That means a mindset where security is everyone’s responsibility across all development stages. ThreatModeler helps in this cultural shift with tools and resources necessary to educate and empower developers to place security first in their coding practices.
Developers play a huge role in any secure by design initiative. A blog by ThreatModeler describes one good way to know if developers are really developing secure code: Well, according to the article, the requirement is that a developer should be certain about the security of their code: before deployment. This realization can be done by “shifting security left” in the development lifecycle by baking in security from the very beginning. Another principal tool in this undertaking is continuous threat modeling. By incorporating threat modeling in the development process, we will be able to make sure that developers are following secure design patterns and not accidentally adding vulnerabilities.
In other words, secure by design gives developers the confidence to do their job while their respective organizations can capitalize from the advantages brought about by a more secure digital landscape. Threat modeling provides a foundation for this methodology through the identification of potential threats and mitigating them before they materialize. Adopting threat modeling and secure by design offers us a real opportunity to change the way in which software is developed and to bring into existence a new wave of applications that are much more secure and reliable.
The merging of threat modeling and secure by design denotes a sea change in how we do software development: that in which security is baked right into the DNA of our applications. At the head of this revolution, ThreatModeler makes threat modeling easy, efficient, and integral to the development process. It will be important to have a secure by design approach with robust threat modeling practices for protecting our digital future against fast-evolving cyber threats.
