Purpose and scope of post-incident analysis
Post-incident triage requires rapid identification of how an API was abused, the blast radius, and actionable containment steps. MiddleBrick is a black-box API security scanner designed to surface runtime behavior from a public endpoint, without requiring code changes or agent deployment. It can be used early in triage to map observable indicators, such as unexpected paths or data leakage, against a standardized set of API risks.
How MiddleBrick supports triage activities
The scanner runs in under a minute and focuses on read-only methods plus text-only POST for LLM probes, minimizing impact on production systems. It checks the OWASP API Top 10 (2023) categories most relevant to incident contexts, including authentication bypass, IDOR, excessive data exposure, and input validation issues. Detection of sensitive patterns such as API keys, credit card numbers, and PII helps prioritize which APIs require containment or deeper investigation.
Mapping findings to compliance and evidence
MiddleBrick maps findings to three specific frameworks: PCI-DSS 4.0, SOC 2 Type II, and OWASP API Top 10 (2023). For these frameworks, the tool directly references relevant controls and provides evidence that can be reviewed during audits. For other regulations, it aligns with security controls described in relevant standards and supports audit evidence collection, but it does not certify compliance.
Limitations relevant to post-incident triage
The scanner does not perform intrusive exploitation, so it cannot confirm whether an injected payload would achieve code execution or extract data from backend stores. It does not detect business logic flaws that require domain-specific understanding, nor does it perform blind SSRF testing that relies on out-of-band callbacks. Because it is a scanner and not an auditor, it should be complemented with human review when investigating complex incidents or high-stakes environments.
Operational use and integration during triage
Authenticated scanning allows the tool to exercise endpoints protected by Bearer tokens, API keys, Basic auth, or cookies, provided domain ownership can be verified via DNS TXT or HTTP well-known file. The CLI supports scripted invocation, returning JSON or text output that can be integrated into incident response playbooks. Continuous monitoring in Pro tiers enables rescheduled scans and diffs between runs, highlighting new findings or score drift that may indicate follow-up actions.
