    Prevent Inline Script Execution by Implementing Script-Src CSP Headers in Express

    expressExpress
    >=4.17.1
    nodeNode.js
    >8.9.3

    In this lesson, we'll learn what CSP is and how it can be used to prevent inline scripts from being executed on our vulnerable website. First, we'll deploy CSP in "report only" mode, which will send violations to the endpoint you specify without blocking execution. Then, we'll run CSP in regular mode, which we'll use to completely block inline scripts from executing.
