Threat modeling is a systematic approach to identifying and mitigating potential security threats. It helps in understanding and addressing vulnerabilities before they can be exploited. The aim of the threat modeling process is to get a clear picture of various assets of the organization, the possible threats to these assets, and how and when these threats can be mitigated. The end product of threat modeling is a robust security system. any identification improved  And 1 Early Identification Identify potential security threats at an early stage, enabling timely countermeasures. 2 Improved Understanding Gain a better understanding of the system's BENEFITS security posture, facilitating proactive risk management. OF THREAT 3. Cost-effective Risk Management MODELING Manage security risks in a cost- effective manner by prioritizing threats and allocating resources efficiently. 4 Enhanced Collaboration Promote collaboration and communication between different stakeholders, fostering a holistic approach to security.  Step 1: Define the System Define the system and its boundaries to establish a clear scope for the threat modeling process. Step 2: Identify Threats Identify potential threats that could compromise the security of the system. THREAT Step 3: Evaluate Risks Evaluate the risks associated with identified threats MODELING to prioritize and allocate resources effectively. PROCESS Step 4: Address Critical Threats Prioritize and address the most critical threats through appropriate mitigation strategies. Step 5: Iterate and Improve Continuously iterate and improve the threat model to stay updated with evolving threats and system changes. TYPES OF THREAT MODELS There are several types of security threat models, each tailored to suit different system architectures and requirements. The next figure shows the high-level of the existing threat modeling approaches. COMMON THREAT MODELING METHODOLOGIES X STRIDE THREAT MODEL Created by Microsoft engineers, which is meant to guide the discovery of threats in a system. Used along with a model of the target system, which makes it most effective for evaluating individual systems. STRIDE is an acronym for the types of threats it covers, which are: PASTA THREAT MODEL PASTA stands for Process for Attack Simulation and Threat Analysis PASTA is an attacker-centric methodology with seven steps. It is designed to correlate business objectives with technical requirements. PASTA’s steps guide teams to dynamically identify, count, and prioritize threats. It provides a framework for conducting threat modeling activities throughout the software development lifecycle. CVSS THREAT MODEL The Common Vulnerability Scoring System (CVSS) captures the principal characteristics of a vulnerability and produces a numerical severity score. It provides a scoring system that takes into account various factors such as exploitability, impact, and ease of remediation. The CVSS provides users a common and standardized scoring system within different cyber and cyber-physical platforms CVSS assigns a numerical score to vulnerabilities, allowing organizations to prioritize their response and allocate resources accordingly. DREAD THREAT MODEL DREAD is an acronym that stands for Damage potential, Reproducibility, Exploitability, Affected users, and Discoverability It is a risk assessment model used to evaluate potential risks associated with identified threats. DREAD provides a scoring system for each criterion, allowing for the prioritization of threats based on their severity and impact. DREAD THREAT MODEL  THREAT MODELING While all of these threat model methodologies serve the purpose of identifying and assessing security threats, they differ in their approach and focus. STRIDE focuses on six specific threat categories, PASTA provides a structured methodology for threat analysis, DREAD offers a risk assessment model, and CVSS is primarily used for vulnerability scoring and prioritization. The choice of which methodology to use depends on the specific needs and requirements of the organization or project. It is also common to combine multiple techniques or adapt them to suit the unique context of the system being analyzed. BEST PRACTICES FOR THREAT MODELING Involve all relevant stakeholders Include representatives from various disciplines, such as developers, architects, security professionals, and business stakeholders, to ensure a comprehensive understanding of the system and its security requirements. Start early in the development lifecycle Integrate threat modeling activities as early as possible in the software development process to identify and address security risks from the outset. Use a structured approach Adopt a structured methodology or framework for threat modeling, such as STRIDE, PASTA, or any other suitable technique, to ensure a systematic and consistent analysis of threats. BEST PRACTICES FOR THREAT MODELING Continuously update and refine the threat model Recognize that threat modeling is an iterative process. Regularly review and update the threat model to account for changes in the system and emerging threats. Consider different perspectives and threat modeling techniques Explore multiple threat modeling techniques and perspectives to gain a comprehensive understanding of potential threats and vulnerabilities. Integrate threat modeling with other security processes Connect threat modeling with other security practices, such as risk management, penetration testing, and secure coding practices, to create a holistic and cohesive security approach. BEST PRACTICES FOR THREAT MODELING Document and communicate the findings Document the identified threats, risks, and mitigation strategies in a clear and concise manner. Communicate the results to relevant stakeholders to ensure a shared understanding of the security posture and necessary action points. Seek expertise and external perspectives Consider engaging external security experts or consultants to provide guidance, validation, and an impartial assessment of the threat model. Q/A THANK YOU FOR LISTENING ANY QUESTIONS?
