Injection
SQL-injection detection across query string, JSON body, headers, and cookie surfaces. Catches union, boolean-blind, time-blind, stacked queries, and out-of-band variants. Tuned to keep false-positive cost below the cost of one analyst minute.
- ›200+ SQLi pattern signatures in knowledge base
- ›Encoded payload normalization (URL, base64, hex)
- ›Per-vertical false-positive baseline
Cross-site scripting
Reflected, stored, and DOM-based XSS detection. Watches reflected echo of attacker input, stored payloads on write paths, and DOM sinks invoked from window.location and document.referrer. Pairs with CSP report-uri telemetry.
- ›Reflected echo similarity scoring
- ›Stored-write payload quarantine
- ›DOM-sink instrumentation hooks
SSRF / RCE
Server-side request forgery to internal metadata endpoints, link-local ranges, and cloud IMDS surfaces. Remote-code-execution detection for shell metacharacters, deserialization gadgets, and prototype-pollution chains.
- ›IMDS + link-local + RFC1918 destination blocking
- ›Shell metacharacter + command-chain heuristics
- ›Prototype-pollution key-path detection
04
RULE_FAMILY_AUTH_BYPASS
Authentication abuse
JWT tampering (alg=none, key-confusion, expired-but-reused), session fixation, credential stuffing, and OAuth state-parameter abuse. Cross-references the cross-session identity layer to fingerprint repeat offenders.
- ›JWT alg-confusion + signature-strip detection
- ›Credential-stuffing velocity buckets
- ›LSH + SimHash identity correlation
Rate abuse
Scraper detection, credential-spray, account-enumeration, and inventory-probe patterns. Distinguishes a noisy partner integration from a hostile crawler by behavior, not just IP volume.
- ›Per-endpoint EMA + z-score baselines
- ›Distributed-spray topology via Louvain clustering
- ›User-agent + TLS-fingerprint coherence checks
06
RULE_FAMILY_TENANT_BOUNDARY
Tenant isolation
Cross-tenant data-access attempts: dealerId mismatch on tRPC inputs, foreign-key escapes in raw SQL, and authorization bypass on multi-tenant routes. The category that exists only because Gladius is multi-tenant by design.
- ›Per-request dealerId derivation + audit
- ›Foreign-key tenant-leak scanner
- ›Soft-delete + dealerId composite guard
PII leak detection
Compliance-grade enforcement against accidental PII egress: SSN, driver-license, EIN, and full-PAN patterns in response bodies. Aligned to FTC Safeguards plus state DMV data rules.
- ›Response-body PII scanner (regex + entropy)
- ›Encrypted-column read-path enforcement
- ›Audit log on every classified-field access
Mesh propagation
Signature validation on cross-vertical federation messages. When CRM learns an attacker fingerprint, BDC + Turf + Stone + Detail receive a signed propagation event. This category protects the propagation channel itself.
- ›Ed25519 signature verification on every mesh event
- ›Replay-window enforcement (60s)
- ›Per-vertical install-ID allowlist
