STRIDE Threat Modeling is a complex approach that can help organizations identify and manage risks. It has become an integral part of risk management because it allows organizations to see the big picture and make informed decisions about dealing with threats.
STRIDE stands for Structured, Timed, Reactive, and Explainable Events. It helps you understand how your organization’s different components work together and how they are affected by external events. This blog post will introduce you to STRIDE and explain how it can help you manage risks. We will also show you how to use it to create a threat model for your organization.
How STRIDE Threat Modeling Works
STRIDE Threat Modeling is a process used to identify and assess the potential risks and vulnerabilities of an organization’s information systems. STRIDE is based on the five principles of information security: risk, responsibility, threats, exploitation, and effect.
Each principle is assessed in turn to determine the level of risk associated with it. This risk assessment helps organizations prioritize their efforts and allocate resources to protect critical systems.
STRIDE also helps organizations understand how their systems are being exploited and how they can respond to attacks. By understanding the threat landscape, organizations can create policies and procedures that will protect their data and systems from harm.
The Five Categories of STRIDE Threats
This blog post is about the STRIDE threat modeling methodology and its five categories:
1-Threats from outside sources (e.g., malicious actors)
2-Threats from inside sources (e.g., malicious employees)
3-Threats to infrastructure (e.g., data breaches, systemic vulnerabilities)
4-Threats to users (e.g., social engineering attacks, targeted malware campaigns)
5-Threat intelligence gathering and analysis
The Ten Types of STRIDE Threats
1. Competing demands: Stride organizations must contend with multiple requests from various stakeholders, which can cause tension and competition.
2. Complexity: The more complex the system, the greater the potential for STRIDE threats.
3. Loose coupling: The more loosely coupled a component is to other parts of the system, the more vulnerable it is to STRIDE threats.
4. Ambiguity: There is often ambiguity about who should make decisions and how they should be made, which creates opportunities for STRIDE threats.
5. Data dependencies: Components are linked together so that changes to one can have severe consequences for others.
6. Variability: The systems under scrutiny are subject to change and variability, which makes them more risky targets for STRIDE predators.
7. Complex interfaces: Systems have many interfaces, making identifying and correcting errors or vulnerabilities challenging.
8. Security misconfiguration: Poorly designed or implemented security measures can leave systems open to attack by STRIDE predators.
9. Lack of contingency planning: When unforeseen events occur, organizations may need the plan to respond effectively.
10. Political dynamics: The political environment can be unpredictable and volatile, leading to STRIDE threats.
STRIDE is a modeling and simulation tool used to improve the understanding of how an organization can be attacked. Threat modeling is a process that helps organizations understand their vulnerabilities, assess the risks posed by potential attackers, create contingency plans to mitigate those risks and evaluate whether those plans are effective. STRIDE provides an interactive platform for exploring these risks and making informed management decisions.
