- Prevalence: उच्च बार-बार शोषित
- Impact: उच्च 1 उच्च गंभीरता वाले नियम
- Prevention: प्रलेखित 8 फिक्स उदाहरण

**OWASP:** Security Misconfiguration (A05:2021-Security Misconfiguration) - #5

## Description

This weakness covers three distinct situations: Missing a protection mechanism, using a faulty protection mechanism, or incorrectly applying a protection mechanism. A missing protection mechanism occurs when the application does not defend against a specific attack. A faulty protection mechanism occurs when the application does defend against a specific attack, but the protection mechanism is not implemented correctly.

### JavaScript

Add Helmet middleware to set security headers automatically

## Warning Signs

- [HIGH] Application lacks security headers middleware (helmet, CSP, HSTS, X-Frame-Options, etc.).
Without these headers, the app
- [HIGH] missing security headers middleware (Helmet) to prevent XSS, clickjacking, and MIME sniffing

## Consequences

- सुरक्षा तंत्र को बायपास करना
- अनधिकृत कोड निष्पादित करना
- विशेषाधिकार प्राप्त करना

## Mitigations

- सुरक्षा की अनेक परतें (defense in depth) लागू करें
- कस्टम कार्यान्वयनों के बजाय उद्योग-मानक, परीक्षित सुरक्षा तंत्रों का उपयोग करें
- सुनिश्चित करें कि सुरक्षा तंत्रों को बायपास या निष्क्रिय न किया जा सके

## Detection

- Total rules: 8
- Languages: dockerfile, go, javascript, typescript

## Rules by Language

### Javascript (1 rules)

- **Security Headers in Express.js** [HIGH]: Detects missing security headers middleware (Helmet) to prevent XSS, clickjacking, and MIME sniffing.
  - Remediation: Install and configure helmet middleware:

1. Install: npm install helmet
2. Import: const helmet = require('helmet');
3. Enable: app.use(helmet());

Example:
  const express = require('express');
  const helmet = require('helmet');
  const app = express();
  app.use(helmet());

### Typescript (1 rules)

- **Security Headers in Express.js** [HIGH]: Detects missing security headers middleware (Helmet) to prevent XSS, clickjacking, and MIME sniffing.
  - Remediation: Install and configure helmet middleware:

1. Install: npm install helmet
2. Import: const helmet = require('helmet');
3. Enable: app.use(helmet());

Example:
  const express = require('express');
  const helmet = require('helmet');
  const app = express();
  app.use(helmet());
