Threat Modeling
“Elevate the software security by deploying or rectifying the threat modeling.”
Threat modeling pinpoints the attack vectors that threat agents could use and adopts the perspective of con actors to understand how much damage they can cause. We look beyond the typical canned list of attacks to think about new attacks or attacks that may not have otherwise been considered. Typically, threat modeling is conducted during the design phase of a new application, although it can occur at other stages. The primary objective is to help developers find vulnerabilities and understand the security implications of their design, code, and configuration decisions.
Methodology
Threat modeling is a process that aims to identify potential threats and their corresponding impact on an application, computer system, or IT infra. It involves adopting the perspective of a malicious actor to anticipate the possible damage they could cause. The organization comprehensively analyzes the software specifications and uses documents to understand the system better.

Identifying Threats
It refers to the process of recognizing potential risks that can cause harm or damage to a system or organization. This can include physical threats such as natural disasters or cyber threats such as data breaches.
Mitigating Threats
The risk mitigation process involves implementing measures or actions that reduce the likelihood of risks occurring or limit their impact if they do occur. This can include developing security protocols, implementing safety procedures, or conducting regular risk assessments.
Validating
This process includes the verification of proposed solutions. We verify that the proposed strategies are effective and meet the intended objectives. This can involve testing, evaluating, or analyzing the proposed solutions to ensure they are feasible and effective.
Benefits
Cybersecurity is important because it protects organizational assets and services from malicious attacks and safeguards all types of data, including but not limited to sensitive data, protected health information (PHI), and personally identifiable information (PII) from theft and loss.
Our Approach
Our cyber security approach prioritizes a layered, proactive defense strategy encompassing robust network security, vigilant endpoint protection, strict access controls, regular vulnerability assessments, employee security awareness training, and a rapid incident response plan, ensuring the protection of sensitive data and systems against evolving cyber threats by focusing on the “people, process, and technology” pillars.
Define the System or Application
The first step is to define the scope of the system or application that we are modeling. This includes identifying the assets, such as data, hardware, and software, that need to be protected.
Create A Data Flow Diagram
A data flow diagram (DFD) visualizes how data flows through the system or application. Creating a DFD will help identify potential threats to the system.
Use of STRIDE Threat Model
Using the STRIDE threat model/framework (Spoofing, Tampering, Repudiation, Information Disclosure, Denial of Service, and Elevation of Privilege), identify potential threats to the system or application.
Determine the Impact of Threats
For each potential threat, determine the likelihood of its occurrence and the impact on the system or application. This can be done using risk analysis techniques such as the DREAD threat model (Damage, Reproducibility, Exploitability, Affected Users, Discoverability).
Identify Vulnerabilities
For each discovered threat, identify potential threats to the system or application. This could include external threats such as hacking, malware, or social engineering, as well as internal threats such as insider threats or human error.
Proper Usage of the Controls
Use the existing security controls that are in place to mitigate the identified threats using Preventive, Detective, Corrective, and Compensating models.
FAQ's
What is the threat modeling process?
The threat modeling process is the structured process of pinpointing and transmitting information about the risks that may compromise any device, application, network, or other IT infrastructure.
What are the 4 stages of threat modeling?
Threat modeling helps organizations protect their IT infrastructure against threat agents’ con intentions. Threat modeling often comprises four stages, such as :
• Identify Assets
• Pinpoint Security Risks
• Threat Analysis
• Create Remediation Policies and Implementation of safeguards
What is threat modeling in SDLC?
Threat modeling within SDLC develops cyber attack resilience. Threat modeling during SDLC helps identify the attack vectors that can be utilized against the implemented safeguards, which enables proactively developing countermeasures to secure them.
