Threat Modelling

Threat modelling is a structured process to identify the security requirement and pinpoint security Threats are potential vulnerabilities that may occur with various methods.

Threat modeling works by identifying the types of threats that may cause an application or computer system. It adopts the perspective of malicious hackers to see how much damage they could do. When conducting threat modeling, organizations analyze software architecture, business contacts, and other artifacts. 

This process enables a deep understanding and discovery of important aspects of the system. It typically conducts threat modeling during the design stage of a new application to help the developers easily find the vulnerability and become aware of the security implications of their design code and configuration diseases.

Advantages of Threat Modeling

When performed correctly, threat modelling can provide a clear line of sight across software projects that help to justify security efforts. The threat modelling process helps in organisation for the documentation purpose and keeps it safe. Making a rational decision about how to address them. Otherwise, decision-makers could be rashly based on scanned or no-supporting evidence.

A well-documented threat model provides Assurance that is useful in explaining and defending the security posture of an application or computer system. When the development organisation is serious about the security threat, modelling becomes the more effective way to do the following.

  • Identifying problems in software development life cycle even before coding begins.
  • Evaluating the forms of a tag that you might not otherwise consider
  • Maximize testing budget by helping target testing and code review.
  • Remediate problems before software release and prevent costly recoding post-development.
  • Keep frameworks ahead of internal and external attackers relevant to your application.
  • Model the location of thread agents' motivation skills and capabilities for locating the potential attackers about system architecture.

Misconceptions of Threat Modeling

As a security process, threat modelling is subject to several misconceptions; some people believe linear modelling is only a designed stage activity with the optional exercise for which penetration testing a code can review or substitute something, and the process is too complicated. The following should help dispel some of these misconceptions.

  • Penetration testing and secure code review are effective activities for finding bugs and code. However, security assessments are better at uncovering design flaws.
  • Many developers are intimidated by the idea of threat modeling. At first glance, it can seem daunting. However, suppose you break up the task into workable steps by performing a threat model on a simple web application with complex architecture that becomes systematic. In that case, the key is to start with basic best practices.

Practices of Threat Modeling

The Killer application of thread modelling promotes security understanding across the whole team. It's the first step towards making security everyone's responsibility. Threat modelling is a simple process of considering the five basic practices when creating and updating your threat model.

  • Define The Scope And Depth Of Analysis

Determined to cope with stakeholders, then break down the depth of analysis for individual development teams so they can easily find the threat to the software.

  • Model The Attack Possibility 

Identify software assets, security controls and threat agents and their location for creating a system's security model. Once you have had to model the system, you can identify what could go wrong.

  • Identify Threats

To produce a list of potential attackers, ask the following question: could a threat agent defeat the security control? What must a threat agent do to beat this control?

  • Create A Traceability Matrix of Missing or Weak Security Controls

Consider the trade agents and follow their control parts. Suppose you reach the software asset without going through a security control that's a potential attack. If you go through a rule, consider whether it would be a half-thread agent or the agent would have methods to bypass it.

Threat Modeling Process

Threat modelling process consists of defining Enterprise assets, identifying each application's function in the grand scheme and assembling a security profile for each application. The process continues with identifying and prioritizing potential threats and documenting the harmful events and actions to take to resolve them.

In simple words, thread modelling process is taking and stepping back to assessing your and network assets, identifying react spots, determining what threats exist and coming up with plans to protect or recover.

Why Do We Need Security Threat Modeling?

Cybercrime has extracted a heavy toll on the online community in recent years, as detailed in the piece of security. The report has found that data bridges were exposed to 4.1 billion records in 2019, and social media enables crime Steels dollars 3.25 billion in annual global revenue.

Cyber crime is happening everywhere with businesses and organizations, and even consumers are not safe. According to the data, security breaches have increased by 11% and moved to 67%. Smart organizations and individuals take advantage of reliable resources to fight against this, and sound threat modelling designing for security purposes is essential.
