In application development, security is often an afterthought and seen as an impediment to developers. Therefore, it is given less priority or ignored totally to ensure it meets production deadlines. However, it can lead to more serious vulnerabilities in the production as well as increased risk to the business.
Threat modeling offers a cost-effective way to implement security during the design phase of the software development cycle before even writing any line code. In this article, we will discuss threat modeling, the process of threat modeling, and the advantages of threat modeling in more detail.
What Is Threat Modeling?
Threat modeling is a systematic approach through which businesses can identify potential security vulnerabilities and security threats, determine each threat’s seriousness, and prioritize techniques to protect IT resources. Through continuous threat modeling applications, business and security teams can better protect applications while educating the development team to build a security culture throughout the enterprise.
Threat Modeling Process
Different threat modeling methods consist of different threat modeling steps. However, one of the most concise and straightforward outlines of the threat model is to answer four basic questions.
- What is the team working on?
- What can possibly go wrong?
- What is the team doing about it?
- Did the team do a good job?
As a result, the threat modeling process should include these four broad steps, each of which offers a possible answer to the above questions.
- Decompose the infrastructure or application
- Determine the threat levels
- Determine mitigations and countermeasures
- Rank the threats in order
It might sound like a no-brainer, but not all sectors pay appropriate attention on security. It is the reason why not many organizations and businesses are considering the idea of implementing cyber threat modeling.
Advantages of Threat Modeling
Threat modeling can offer a clear line of sight across different projects when performed correctly. The threat modeling process can also help organizations document the common and knowable security threats to applications. Therefore, allowing the organization and the security team to decide how to handle specific threats. If it is not documented, security teams can make rash decisions with no supportive evidence.
The following are the different things that organizations can achieve through an effective threat modeling process.
- Detect design flaws which the traditional testing methods might overlook.
- Spot problems early in the development cycle, even before a single line of code is written.
- Maximize budget by helping with target testing and code review.
- Evaluate a more sophisticated form of attack, which otherwise you might not consider.
- Remediate problems even before the release to prevent costly recoding after deployment.
- Look for threats beyond the standard attack to the security issues which are unique to the application.
- Highlight threat agents, assets, and controls to deduce areas that the cyber-attackers might target.
What Are the Different Types of Threat Modeling Tools Available?
There are several different threat modeling tools available that can help with threat modeling. The best threat modeling tools can help the security team, and other key stakeholders visualize, design, plan for and predict potential external and internal threats to the organization. These tools have been designed to meet the ever-changing demands of the threat environment. The following are some of the best threat modeling tools available for organizations to perform threat modeling.
- Microsoft threat modeling tool
- OWASP Threat Dragon
