Threat Analysis

What Is an Attack Surface?

An attack surface encompasses all points, interfaces, and avenues through which threat actors can enter or extract information from a system, network, or application. This includes:

• Cloud infrastructure (configurations, access controls, data storage)
• Software (applications, operating systems, dependencies)
• Network interfaces (devices, ports, protocols, services)
• Web applications (websites, web services, platforms)
• Hardware devices (IoT devices, servers, routers)
• Endpoints (computers, smartphones, tablets)
• Human factors (users targeted via social engineering or phishing)
• Third-party services or integrations (external dependencies)

What Is Threat Analysis?

Threat analysis involves identifying potential threats, understanding severity and impact, and developing mitigation plans. It utilizes data from commercial threat feeds, industry reports, and internal intelligence to identify and assess threat actors within business-specific contexts, concluding with mitigation strategies including technical, administrative, or physical security controls.

What Are the Types of Threat Analysis?

Three primary types exist: attack-centric (evaluating from attacker's perspective), software-centric (focusing on application design and code vulnerabilities), and checklist-based (simpler execution with trade-offs in analytical depth).

Why Is It Important?

Threat analysis enables organizations to understand adversaries and weaknesses, address application threats proactively, and respond more effectively to incidents while minimizing attack impact.

What Are Some Key Considerations?

Benefits include proactive vulnerability closure, optimized incident response, and resource allocation. However, analyses are limited to available data and susceptible to bias and require ongoing updates.

How Is It Related to Threat Modeling?

Threat analysis constitutes a component of threat modeling, informing software development lifecycles and providing organizations comprehensive visibility of attack surfaces and vulnerabilities.
