“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.
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.
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.
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.
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.
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.
To uncover all potential attack paths and vulnerabilities, we launch both a manual and an automated security scan in this step. In order to assess the application's security, we then execute exploits against it. For a high degree of penetration, we employ several techniques, open-source scripts, and internal tools. To secure your application and its data, all of these are carefully carried out.
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.
Use the existing security controls that are in place to mitigate the identified threats using Preventive, Detective, Corrective, and Compensating models.
Determine and rectify the gaps in the existing controls that could leave the system or application vulnerable to attack.
Map the identified threats to the MITRE ATT&CK framework to determine the tactics and techniques that attackers could use to exploit the identified vulnerabilities.
Based on the identified gaps, design and develop recommendations for additional security controls or changes to existing controls to protect the system or application in a better way.
Prioritize the recommendations based on the severity of the threats and the cost and feasibility of implementing the recommended controls.
Implement the recommended controls to reduce the risk of harm to the system or application.
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.
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.
