What is OWASP LLM Top 10 LLM-VECTOR-AUTH?

OWASP LLM Top 10 LLM-VECTOR-AUTH (Vector Database Authentication and Network Isolation) requires: Vector DB requires authentication for all access; network isolation prevents internet exposure. This is a high-severity control.

How does EchelonGraph detect OWASP LLM Top 10 LLM-VECTOR-AUTH violations?

EchelonGraph automatically detects OWASP LLM Top 10 LLM-VECTOR-AUTH violations using scanner rule OWASP-LLM-VEC-001. The scanner checks cloud infrastructure configurations in real-time and flags non-compliant resources.

What audit questions are asked for OWASP LLM Top 10 LLM-VECTOR-AUTH?

Run our Shadow AI Radar on your domain — what vector DBs are exposed? What authentication is required on each? What network policy restricts ingress? How often are vector DB credentials rotated?

Vector Database Authentication and Network Isolation

Description

Vector DB requires authentication for all access; network isolation prevents internet exposure.

⚠️ Risk Impact

EchelonGraph's Shadow AI Radar continuously discovers internet-exposed Milvus, Weaviate, Qdrant, and Chroma instances. Many require no authentication; data flows out trivially.

🔍 How EchelonGraph Detects This

OWASP-LLM-VEC-001Automated scanner rule

EchelonGraph's Tier 1 Cloud Scanner automatically checks for this condition across all connected cloud accounts. Violations are flagged as high-severity findings with remediation guidance.

🖥️ Manual Verification

terminal

# Verify Milvus auth is enabled
grep -E 'common.security.authorizationEnabled.*true' /etc/milvus/milvus.yaml

🔧 Remediation

Enable authentication on every vector DB. Restrict ingress to internal networks via NetworkPolicy / VPC firewall. Rotate credentials quarterly. Monitor outbound queries.

💀 Real-World Attack Scenario

Wiz Research found 35+ exposed Milvus instances in Jan 2025 alone — most with default-no-auth config. Affected orgs included AI startups handling sensitive enterprise embeddings. Estimated data exposure: undisclosed but material across multiple incidents.

💰 Cost of Non-Compliance

Exposed-vector-DB incidents in 2024-2025: avg $1.8M per case (Wiz AI Threat Report).

📋 Audit Questions

1.Run our Shadow AI Radar on your domain — what vector DBs are exposed?
2.What authentication is required on each?
3.What network policy restricts ingress?
4.How often are vector DB credentials rotated?

🏗️ Infrastructure as Code Fix

main.tf

resource "helm_release" "milvus" {
  name       = "milvus"
  namespace  = "ai"
  chart      = "milvus"
  repository = "https://zilliztech.github.io/milvus-helm"
  set { name = "common.security.authorizationEnabled"; value = "true" }
  set { name = "service.type"; value = "ClusterIP" }  # Never LoadBalancer
}

⚡ Common Pitfalls

⛔Helm-installing vector DBs with chart defaults (often no auth)
⛔Service type LoadBalancer exposing to internet
⛔No credential rotation

📈 Business Value

Vector DB hardening prevents the highest-frequency 2025 AI infra incident. EchelonGraph customers detect exposure in <60 seconds via Shadow AI Radar.

⏱️ Effort Estimate

Manual

1-2 weeks per cluster for vector DB audit + hardening

With EchelonGraph

EchelonGraph's Shadow AI Radar continuously monitors for exposed vector DBs across all customers
