What is a Threat Model?
A threat model is a structured framework used to identify, assess, and prioritize potential security threats within a system or network. In the context of Network Security, it helps organizations understand vulnerabilities and develop strategies to mitigate risks. This model considers various elements, including assets (e.g., data, hardware), potential attackers (e.g., hackers, insiders), attack vectors (e.g., malware, phishing), and the impact of potential breaches.
Key Components of a Threat Model:
- Assets: Identify what must be protected, such as sensitive data or network infrastructure.
- Threat Actors: Define who might attack the network, including their motivations and capabilities.
- Attack Vectors: Examine possible methods attackers could use to exploit vulnerabilities.
- Impact Assessment: Evaluate the potential consequences of security breaches on the organization.
- Mitigation Strategies: Develop countermeasures to reduce risks identified during the assessment.
By adopting a comprehensive threat model, organizations can enhance their Information Security practices, effectively navigating the complex landscape of Cybersecurity. Continuous updates and revisiting the threat model are essential to adapt to new threats as technology evolves.
