# Read-Only Access

## Overview

Detects any attempt to use SQL operations that require more than read-only access.
Activating this policy is important to avoid the accidental or malicious execution of dangerous SQL queries like DROP, INSERT, UPDATE, and others.

> **User:** "I have a table called employees which contains a salary column, how can I update the salary for an employee called John?"
>
> **LLM Response:** "Response restricted due to request for write access."

## Policy details

This policy ensures that any SQL command requiring write access is detected.

Only SELECT statements are allowed, preventing any modification of the database.
