# Usage of insecure websocket connection

## Overview

* **Rule ID**: `javascript_lang_websocket_insecure`
* **Applicable Languages**: Javascript
* **Weakness ID**: CWE-319

## Description

Your application is vulnerable when connecting to APIs via insecure websocket connections. This risk arises because data transmitted over these connections can be intercepted or altered by attackers. Make sure all websocket connections in your application use SSL to encrypt data in transit, protecting it from unauthorized access.

## Remediation Guidelines

* **Avoid** starting websocket connections without SSL, as these connections are susceptible to interception and compromise.

  ```javascript
  const client = new WebSocket('ws://insecure-api.com'); // insecure
  ```
* **Ensure** that all websocket connections are secured with SSL. This encrypts the transmitted data, safeguarding it from eavesdropping and tampering.

  ```javascript
  const client = new WebSocket('wss://secure-api.com');

  ```
