securescout-iast 1.0.3

Interactive Application Security Testing (IAST) runtime agent for Python

securescout-iast

Interactive Application Security Testing (IAST) runtime agent for Python web applications. Detects SQL injection vulnerabilities in real time by tracing untrusted request data as it flows into database queries during normal application traffic.

How it works

securescout-iast tags incoming request data (query parameters, headers, cookies, and JSON/form body) at the ASGI layer, then watches for that data appearing in raw SQL execute calls. If untrusted input reaches a database query without being safely parameterized, a finding is reported to your SecureScout dashboard — confirmed by actual runtime execution, not static guesswork.

Installation

pip install securescout-iast

Quick start (FastAPI / Starlette)

from fastapi import FastAPI
from securescout_iast import SecureScoutIastMiddleware, init

app = FastAPI()

init(
    api_key="ssk_live_your_api_key",
    project_id="your-project-id",
)
app.add_middleware(SecureScoutIastMiddleware)

Get your API key and project ID from Settings → API Keys and your project's Runtime (IAST) tab in the SecureScout dashboard.

Supported database drivers

• psycopg2 (sync PostgreSQL)
• asyncpg (async PostgreSQL, including async SQLAlchemy)

Drivers are detected automatically. If a driver isn't installed in your environment, that patch is silently skipped — no errors, no extra dependencies pulled in.

Detected vulnerability classes

• SQL Injection (CWE-89) — v1

Safety guarantees

• init() never raises. Misconfiguration or network issues degrade to a silent no-op, never a crash.
• Your request and database driver behavior are never modified — the agent only observes.
• Request bodies over 1MB are not buffered for taint analysis (still passed through to your app unmodified).
• No third-party dependencies. Pure standard library.

Privacy

This agent inspects request data and SQL query text locally, within your application process, to detect taint matches. Only confirmed findings (rule type, query snippet, stack trace, endpoint) are sent to SecureScout — never raw request bodies or full traffic.

Disabling & Uninstallation

To completely disable or remove the SecureScout IAST agent:

1. Remove Middleware: Remove the SecureScoutIastMiddleware (ASGI) or SecureScoutWsgiMiddleware (WSGI) wrapper from your application setup.
2. Remove Initialization: Delete or comment out the init(...) call in your application entrypoint.
3. Uninstall the Package:

   pip uninstall securescout-iast

Temporary Disable (Environment-driven)

To disable the agent without modifying imports, wrap init() with an environment variable check:

import os
from securescout_iast import init

if os.environ.get("SECURESCOUT_IAST_DISABLED") != "true":
    init(
        api_key="your-api-key",
        project_id="your-project-id"
    )

Set SECURESCOUT_IAST_DISABLED=true in your environment to disable the agent at runtime with zero code changes.
