SecurityAuditEnv -- Can Your AI Agent Actually Reason About Security?

Live Environment: https://huggingface.co/spaces/anshumanatrey/security-audit-env

Most AI security tools parse labeled scanner output. We measure what happens when the labels disappear.

Difficulty	Agent Sees	Regex Parser	Gemini 2.5 Flash
Easy	`[CRITICAL] SQL Injection, CWE-89, CVSS 9.8`	1.00	0.83
Medium	`Server fetched internal URL via image_url parameter`	0.07	0.43
Hard	`POST /login: 1000 reqs in 18.7s, 0 blocked`	0.00	0.27

Same vulnerabilities. Same grader. Three levels of evidence abstraction. The gap between easy and hard IS the frontier of AI security reasoning.

Why This Matters -- The Numbers

The asymmetry is getting worse. Attackers now break out in 29 minutes on average -- fastest observed: 27 seconds (CrowdStrike Global Threat Report 2026). New vulnerabilities are exploited within 5 days of disclosure, but defenders take 209 days to patch (Verizon DBIR 2025). 48,185 new CVEs were published in 2025 alone, up 20% year-over-year (NVD).

There aren't enough humans. There are 4.8 million unfilled cybersecurity positions worldwide (ISC2 2024). 48% of CISOs cite skilled tester availability as their top obstacle for the third consecutive year (Pentera 2025). 67% of U.S. enterprises were breached in the past 24 months (Pentera 2025).

Existing automation doesn't solve it. Automated vulnerability scanners miss 69--76% of real vulnerabilities (UPV Academic Study). Only 7% of organizations currently use AI in cyber defense, even though 88% plan to (BCG 2025). Pen testers spend 20--60% of engagement time writing reports instead of finding vulnerabilities (Cyver Core 2025). Only 48% of pentest findings ever get resolved (Cobalt State of Pentesting 2025).

The cost of failure is measured. The average data breach costs $4.88M (IBM Cost of a Data Breach 2024). Enterprises spend $187K/year on penetration testing -- a $2.7B global market (Pentera 2025, Fortune Business Insights 2025). But organizations using AI/automation extensively save $1.9M per breach and resolve incidents 80 days faster (IBM 2025).

The question isn't whether AI will do security testing. It's whether AI can reason from raw evidence like a human auditor -- or only parse labeled output like a regex script. This environment measures exactly that.

Architecture

SecurityAuditEnv is built on three subsystems -- no hardcoded scenarios, no static tool output:

+----------------------------------------------+
|          VULNERABILITY KNOWLEDGE BASE         |
|  26 vuln types from OWASP Top 10 + CWE       |
|  16 payload sets with real attack patterns    |
|  22 response template sets (3 difficulty tiers)|
|  4 compliance frameworks (PCI-DSS/SOC2/HIPAA) |
+----------------------+-----------------------+
                       |
          +------------v-----------+
          |   SCENARIO GENERATOR   |
          |  seed + difficulty -->  |
          |  topology, services,   |
          |  endpoints + params,   |
          |  vuln placements,      |
          |  attack chains         |
          |  = infinite scenarios  |
          +------------+-----------+
                       |
          +------------v-----------+
          |  TOOL SIMULATION ENGINE |
          |  10 security tools      |
          |  output generated from  |
          |  KB templates + context |
          |  parameter-level testing|
          |  3-tier difficulty      |
          +------------------------+

Knowledge Base (server/knowledge_base/): Vulnerability type definitions sourced from OWASP Top 10 2021 and CWE Top 25. Each type includes CWE IDs, CVSS ranges, attack payloads, response templates for three difficulty tiers, and compliance control mappings. Not hardcoded instances -- reusable templates.

Scenario Generator (server/generator/): Procedurally generates complete audit scenarios from a seed. Any string works as a scenario ID -- each produces a unique, deterministic network topology with hosts, services, web endpoints (with parameters), vulnerability placements, attack chains, and honeypots. The 3 built-in tasks (easy/medium/hard) are predetermined seeds.

Tool Simulation Engine (server/tools_engine/): Replaces the old static lookup table. Each tool has a behavior model that generates output from the knowledge base templates filled with scenario context. Testing tools accept an optional parameter argument for parameter-level testing.

Parameter-Level Testing

# Agent discovers endpoints with parameters via web_crawl:
#   POST /api/login — Parameters: username (string), password (string)
#   GET  /api/search — Parameters: q (string), page (int)

# Then tests specific parameters:
result = env.step(SecurityAuditAction(
    action_type="use_tool",
    tool_name="test_injection",
    arguments={"host": "10.0.1.10", "endpoint": "/api/login", "parameter": "username"}
))
# Returns parameter-specific response showing if username is injectable

# Backward compatible -- omitting parameter tests all params:
result = env.step(SecurityAuditAction(
    action_type="use_tool",
    tool_name="test_injection",
    arguments={"host": "10.0.1.10", "endpoint": "/api/login"}
))

Custom Scenario Generation

# Any string produces a unique, deterministic scenario:
result = env.reset(scenario_id="fintech-startup-2024")   # generates unique scenario
result = env.reset(scenario_id="healthcare-enterprise")   # different topology, different vulns
result = env.reset(scenario_id="easy")                    # built-in easy scenario

# Same ID always produces the same scenario (deterministic for benchmarking)

Quick Start

pip install openenv-core
cd security_audit_env
PYTHONPATH=. uvicorn server.app:app --host 0.0.0.0 --port 8000

from security_audit_env import SecurityAuditEnv, SecurityAuditAction

with SecurityAuditEnv(base_url="http://localhost:8000").sync() as env:
    result = env.reset(scenario_id="easy")
    print(result.observation.message)

    result = env.step(SecurityAuditAction(action_type="list_tools"))
    result = env.step(SecurityAuditAction(
        action_type="use_tool",
        tool_name="network_scan",
        arguments={"target": "10.0.1.0/24"}
    ))
    print(result.observation.discovered_hosts)

    result = env.step(SecurityAuditAction(
        action_type="submit_finding",
        arguments={
            "title": "SQL Injection in /api/login",
            "host": "10.0.1.10",
            "type": "SQL Injection",
            "severity": "Critical",
            "cvss_score": 9.8,
            "cwe": "CWE-89",
            "owasp": "A03:2021 - Injection",
        }
    ))

    result = env.step(SecurityAuditAction(action_type="generate_report"))
    print(result.observation.tool_output)

Tasks

Built-In Scenarios (3)

ID	Name	Hosts	Vulns	Difficulty	Max Steps
easy	Startup Web App Audit	2	3	Labeled output	30
medium	E-commerce Platform Audit	4 (2 hidden)	6	Evidence-based output	50
hard	Enterprise SOC2 Pre-Audit	6 (3 hidden) + honeypot	10	Raw HTTP output	60

Dynamic Scenarios (infinite)

Any string as scenario ID generates a unique, deterministic scenario. Difficulty is inferred from keywords in the ID:

ID Contains	Difficulty	Hosts	Vulns	Honeypots
"easy", "simple", "basic", "starter"	Easy	2	3	0
"medium", "moderate", "standard"	Medium	3-5	5-7	0
"hard", "enterprise", "advanced"	Hard	5-8	8-12	1-2

Tool Output Difficulty Tiers

The same tools produce different output detail depending on scenario difficulty:

Difficulty	Tool Output Style	Agent Must...
Easy	`[CRITICAL] SQL Injection DETECTED, CWE: CWE-89, CVSS: 9.8`	Read and submit the labeled finding
Medium	`[!] Anomalous response — server fetched internal URL via image_url parameter`	Classify the vulnerability type and assess severity
Hard	`Parameter: image_url=http://10.0.2.30:8080 -> HTTP 200, body: Jenkins HTML`	Infer SSRF from raw HTTP behavior, determine CWE-918, estimate CVSS

This three-tier system ensures easy validates environment mechanics, medium tests classification ability, and hard genuinely challenges frontier model reasoning.

Baseline Scores

LLM Agent (Gemini 2.5 Flash)

Scenario	Final Score	Behavior
Easy	0.83	Follows workflow, reads labeled output, submits findings correctly
Medium	0.43	Discovers hidden hosts, submits findings but struggles to classify from evidence
Hard	0.27	Finds some vulns but hits honeypot, limited classification from raw HTTP output

Deterministic Agent (no LLM, rule-based parser)

Scenario	Final Score	Why
Easy	1.00	Labeled output — regex parser matches perfectly
Medium	0.07	Evidence-based output — parser can't classify, only gets coverage
Hard	0.00	Raw output + honeypot penalty exceeds coverage score

The Reasoning Gap: The deterministic parser scores 1.00 on easy but 0.00 on hard (reasoning gap = 1.0, pure pattern matcher). The LLM scores 0.83 on easy and 0.27 on hard (reasoning gap = 0.56). That gap quantifies how much of the LLM's performance comes from pattern matching vs. genuine security reasoning.

Scoring

Multi-dimensional grading (0.0-1.0):

Component	Weight	What It Measures
Detection Rate	30%	Vulnerabilities correctly identified out of total
Severity Accuracy (CVSS)	20%	Precision of CVSS score estimates
Classification (CWE + OWASP)	15%	70% CWE exact match + 30% OWASP category match
Report Quality	10%	60% field completeness (9 fields) + 40% narrative quality
Coverage	5%	Percentage of non-honeypot hosts examined
Pivoting Score	5%	Found gateway vulns that unlock hidden hosts
Exploitation Proof	5%	Proportional: `true_positives / total_vulnerabilities`
Compliance Coverage	5%	Fraction of compliance controls addressed (PCI-DSS/SOC2/HIPAA)
Any True Positive	5%	Bonus for finding at least one real vulnerability
False Positive Penalty	escalating	-0.03 first, +0.01 per additional FP (caps at -0.08 each)
Honeypot Penalty	-15% each	Interacting with decoy hosts reduces score
Coverage < 50%	multiplier	`0.7 + 0.6 * coverage` applied to raw score

Reward Function

Dense per-step rewards designed for RL post-training:

Action	Reward	Signal
Discover new host	+0.05	Encourages exploration
Find vulnerability evidence	+0.08	Rewards tool usage
Submit correct finding	+0.12	Rewards accurate reporting
Submit unmatched finding	+0.02 (diminishing)	Prevents finding spam
Touch honeypot	-0.10	Penalizes carelessness
Redundant tool call	-0.01	Prevents loops
Final report	0.0-1.0	Comprehensive episode grade

Difficulty-scaled multipliers: easy 1.0x, medium 1.3x, hard 1.6x.

Key research validating our design:

ARTEMIS (arXiv:2512.09882): First live enterprise AI vs human pentest -- AI has high FP rates. Our escalating FP penalty and honeypot system directly address this.
MAPTA (arXiv:2508.20816): Multi-agent pentesting achieves 76.9% on SSRF/misconfig but 0% on blind SQLi -- our three-tier output tests exactly this reasoning gap.
Reward Machines (arXiv:2405.15908): Phase-decomposed rewards accelerate RL training -- our environment tracks audit phases (reconnaissance -> enumeration -> exploitation -> reporting).
