Overview

SecurityUse is a unified security scanning platform for Python applications. It detects vulnerabilities in dependencies, misconfigurations in Infrastructure as Code, and provides runtime attack detection for web applications.

$ security-use scan all ./my-project

 SecurityUse v0.2.1

 Scanning dependencies...
 ✓ Found 3 vulnerabilities in 47 packages

 Scanning IaC files...
 ✓ Found 2 misconfigurations in 5 files

 ┌─────────────────────────────────────────────────────────────────┐
 │ CRITICAL  1   │   HIGH  2   │   MEDIUM  2   │   LOW  0         │
 └─────────────────────────────────────────────────────────────────┘

Features

Dependency Vulnerability Scanning

Detect known CVEs in your Python dependencies using the OSV database.

• Multi-format support: requirements.txt, Pipfile, pyproject.toml, poetry.lock, package.json, pom.xml
• Accurate matching: Uses package ecosystem data for precise vulnerability matching
• Severity scoring: CVSS-based severity ratings (Critical, High, Medium, Low)
• Fix suggestions: Recommends safe versions to upgrade to

Infrastructure as Code Scanning

Find security misconfigurations before they reach production.

Platform	Formats	Rules
Terraform	.tf, .tf.json	25+
CloudFormation	.yaml, .yml, .json	20+
AWS	S3, EC2, IAM, RDS, Lambda	Full coverage

Detects:

• Unencrypted storage and databases
• Overly permissive IAM policies
• Public access to sensitive resources
• Missing logging and monitoring
• Insecure network configurations

Runtime Security Sensor

Real-time attack detection middleware for FastAPI and Flask applications.

from fastapi import FastAPI
from security_use.sensor import SecurityMiddleware

app = FastAPI()
app.add_middleware(
    SecurityMiddleware,
    webhook_url="https://your-siem.com/alerts",
    block_on_detection=True,
)

Detects:

• SQL Injection (' OR 1=1--, UNION SELECT, etc.)
• Cross-Site Scripting (<script>, javascript:, event handlers)
• Path Traversal (../, %2e%2e%2f, etc.)
• Command Injection (;cat /etc/passwd, backticks, $())
• Rate limit violations
• Suspicious user agents (sqlmap, nikto, etc.)

Auto-Fix

Automatically remediate security issues with a single command.

security-use fix ./my-project

Dependency Fixes:

• Updates vulnerable packages to patched versions
• Supports requirements.txt, Pipfile, pyproject.toml

IaC Fixes:

Rule	Issue	Auto-Fix
CKV_AWS_19	S3 bucket without encryption	Adds AES256 server-side encryption
CKV_AWS_20	S3 bucket with public access	Changes ACL to private
CKV_AWS_3	EBS volume unencrypted	Sets encrypted = true
CKV_AWS_16	RDS instance unencrypted	Adds storage_encrypted = true
CKV_AWS_23	Open security group ingress	Restricts CIDR blocks

Installation

pip install security-use

With optional dependencies:

# For runtime sensor with FastAPI/Flask
pip install security-use[sensor]

# For development
pip install security-use[dev]

Requirements: Python 3.10+

Quick Start

Command Line Interface

# Scan dependencies for vulnerabilities
security-use scan deps ./my-project

# Scan Infrastructure as Code
security-use scan iac ./terraform

# Scan everything
security-use scan all ./my-project

# Output as JSON
security-use scan all ./my-project --format json

# Output as SARIF (for GitHub Code Scanning)
security-use scan all ./my-project --format sarif > results.sarif

# Auto-fix vulnerabilities and IaC misconfigurations
security-use fix ./my-project

# Auto-fix with options
security-use fix ./my-project --dry-run      # Preview changes
security-use fix ./my-project --deps-only    # Only fix dependencies
security-use fix ./my-project --iac-only     # Only fix IaC issues

Python API

from security_use import scan_dependencies, scan_iac

# Scan dependencies
result = scan_dependencies("./my-project")

print(f"Found {len(result.vulnerabilities)} vulnerabilities")
for vuln in result.vulnerabilities:
    print(f"  {vuln.severity.value}: {vuln.package} - {vuln.title}")

# Scan IaC
result = scan_iac("./terraform")

for finding in result.iac_findings:
    print(f"  [{finding.severity.value}] {finding.rule_id}")
    print(f"    {finding.title}")
    print(f"    {finding.file_path}:{finding.line_number}")

Runtime Sensor

FastAPI (ASGI):

from fastapi import FastAPI
from security_use.sensor import SecurityMiddleware

app = FastAPI()

app.add_middleware(
    SecurityMiddleware,
    webhook_url="https://your-siem.com/webhook",
    block_on_detection=True,         # Return 403 on attacks
    excluded_paths=["/health", "/metrics"],
    rate_limit_threshold=100,        # Requests per minute per IP
)

@app.get("/api/users")
def get_users():
    return {"users": []}

Flask (WSGI):

from flask import Flask
from security_use.sensor import FlaskSecurityMiddleware

app = Flask(__name__)

app.wsgi_app = FlaskSecurityMiddleware(
    app.wsgi_app,
    webhook_url="https://your-siem.com/webhook",
    block_on_detection=False,  # Log only, don't block
)

@app.route("/api/users")
def get_users():
    return {"users": []}

  "version": "1.0",
  "event": {
    "id": "evt_abc123def456",
    "type": "security_alert",
