FedRAMP moderate prep

FedRAMP moderate control requirements emphasize identity verification, access control, audit logging, and incident response for cloud-based services. APIs that support federal workloads must demonstrate consistent authentication, authorization, and visibility into access patterns. Meeting these expectations requires automated, repeatable checks that validate security configurations rather than relying on manual reviews. Teams often underestimate the scope of API inventory and the impact of weak authentication or excessive data exposure on shared services.

Without a repeatable scanning workflow, organizations miss misconfigured authentication mechanisms, over-permissive CORS rules, and unversioned endpoints that expose sensitive operations. Adversaries commonly exploit weak JWT handling, missing security headers, and verbose error messages that leak stack traces or internal paths. Teams also overlook authorization flaws such as IDOR and privilege escalation when no systematic checks are in place. These gaps create audit findings during FedRAMP assessments and increase remediation effort late in the lifecycle.

Begin with an inventory of all public and restricted endpoints using OpenAPI specifications and runtime discovery. Run automated scans to map authentication requirements, validate security headers, and detect excessive data exposure. Incorporate scans into CI/CD so that new deployments are evaluated before they reach production. Track score trends over time and generate evidence artifacts for control reviews. Example CLI usage:

middlebrick scan https://api.example.com --output json

Authenticated scans can be configured for Bearer or API key credentials after domain verification, ensuring only the domain owner can submit credentials.

middleBrick operates as a black-box scanner that checks API behaviors without requiring code or agent access. It parses OpenAPI 3.0, 3.1, and Swagger 2.0 definitions and correlates spec definitions with runtime findings. Detection coverage aligned to FedRAMP-relevant areas includes:

• Authentication bypass and JWT misconfigurations, including none algorithm and expired tokens
• Authorization flaws such as IDOR, BOLA, and privilege escalation via admin endpoints
• Data exposure risks including PII patterns, API key leakage, and error message disclosure
• Input validation issues like dangerous HTTP methods, wildcard CORS, and debug endpoints
• Transport security checks, such as HTTPS redirects, HSTS, and cookie flags

For LLM-facing APIs, the scanner includes adversarial probes for prompt injection and jailbreak attempts relevant to AI-assisted endpoints.

middleBrick maps findings to OWASP API Top 10 (2023) and supports audit evidence collection for SOC 2 Type II and PCI-DSS 4.0 control activities. Each finding includes prioritized remediation guidance to help developers address specific issues, such as tightening authentication requirements, enforcing least-privilege access, and removing sensitive data from responses. The tool does not fix code or block traffic; it provides the detection and context needed for teams to implement precise fixes.

middleBrick is a scanning tool and cannot certify compliance or replace formal audits. It does not perform intrusive payloads like active SQL injection or command injection, which fall outside its read-only design. Organizations must still apply human expertise to evaluate business logic and contextual risks. Continuous monitoring options are available to track score drift and surface new findings across scheduled intervals, with alerts and signed webhooks to support incident response processes.
