API BOM Overview

API BOM Overview

Severity Color Mapping:

• 🔴 Red = Critical vulnerabilities

• 🟧 Orange = High vulnerabilities

• 🟨 Yellow = Medium vulnerabilities

1. Day in the Life of an AppSec Engineer Using This Chart

An AppSec engineer responsible for securing applications and APIs would use this API BOM view to:

• Start-of-Day API Triage:

  • Check which applications and endpoints have critical or high-risk vulnerabilities across APIs.

  • In this example, Application Name 1 is top priority with 6 critical vulnerabilities.

• Remediation Planning:

  • Drill down by endpoint, function, and framework (e.g., getPerson() in express.js) to prepare targeted fixes or assign tasks to developers.

• Repository-Level Action:

  • Uses the repository mapping (e.g., user-management) to file JIRA tickets, trigger CI/CD patch workflows, or conduct code reviews.

• Cross-Team Coordination:

  • Coordinates with developers and API owners to ensure patches or mitigations are prioritized where multiple vulnerabilities are stacked on a single endpoint.

2. Impact on AppSec Operations

This API BOM breakdown improves precision, prioritization, and accountability in API security operations:

• API-Centric Vulnerability Management:

  • Provides granular visibility into API endpoints, functions, and frameworks tied to known vulnerabilities.

• Consolidated Risk Context:

  • By grouping insights at the app, endpoint, and repo level, security teams can remediate smarter—not just faster.

• Faster SLA Monitoring and Escalation:

  • Enables teams to track how long vulnerabilities persist, identify risky trends, and enforce patching SLAs for APIs.

• Reusable Fix Strategy:

  • Identifies common endpoints or reusable components (e.g., /persons/{id}) that are vulnerable across multiple apps, allowing bulk fixes or shared remediations.

---

3. What Are the Decisions It Drives?

• Which apps and endpoints need immediate attention?

  • Application Name 1 and the /persons/{id} endpoint in getPerson() function have multiple critical vulnerabilities—these are top priority.

• Is the same vulnerable API reused in multiple places?

  • Yes—the same API and endpoint is listed multiple times under Application Name 1, likely due to detection duplication or layered insight categorization.

• Do we need to isolate or temporarily block access to certain APIs?

  • Possibly—for example, if /persons/{id} is public-facing, runtime mitigations like rate limiting, auth hardening, or WAF rules may be needed until patched.

• Which repositories need focused code-level intervention?

  • The user-management repository is the source for all vulnerabilities in Application Name 1—it should be triaged and prioritized in development backlog.

• Are there shared framework concerns?

  • Yes—all vulnerabilities stem from endpoints built using express.js, which may indicate framework-specific security gaps or usage patterns.

4. Detailed Description of the Chart

This hierarchical API BOM (Bill of Materials) view maps APIs, endpoints, and related vulnerabilities per application:

Field	Description
App Name	Lists all applications scanned for API-level vulnerabilities.
API	The name of the API or service exposing endpoints (e.g., Damn-vulnerable-sca API).
Endpoint	Specific API paths (e.g., /persons/{id}) found to be vulnerable.
Function	Code-level function handling the endpoint (e.g., getPerson() function).
Framework	Tech stack used (e.g., expressjs for Node-based services).
Repository	Git repo from which the vulnerable endpoint originates (e.g., user-management).
Insights	Severity breakdown per row — 🔴 Critical, 🟧 High, 🟨 Medium vulnerabilities.

• Applications 2–4 also show a combination of critical to medium-level vulnerabilities but with fewer entries, indicating less immediate risk or fewer detected APIs.

Final Thoughts

This API BOM Overview enables AppSec teams to:

✅ Prioritize remediation by endpoint risk and reuse ✅ Drill down from app to repo to function for actionable fixes ✅ Identify framework or repo patterns contributing to recurring API issues ✅ Improve coordination between AppSec and development teams
