[ Whitelisting ] is a practice of explicitly granting entities privileges or allowing access to some or all resources.

Content security policy - CSP

Content Security Policy (CSP) is an effective security measure that is designed to prevent many client-side vulnerabilities such as Cross-Site Scripting.

Four main weaknesses in CSP

It's not always easy to add CSP to an existing website because most websites and web apps rely on third-party JavaScript libraries and code. Developers often have to use shortcuts and trade-offs between security and functionality.

  • Whitelisting
  • CSP bypass techniques
  • Incorrect CSP implementation
  • CSP implementation tradeoffs

CSP Supply chain attacks

Since web browsers load JavaScript code from external domains or subdomains of the website (e.g., code.company.com) developers, end up whitelisting all external and internal hosts of scripts to avoid breaking required functionality removing the very protection CSP is supposed to provide.

Defense in Depth

By activate multi-layered defenses against e-skimming attacks, you will be able to prevent the threat. This approach stops unauthorized access to data by first-party and third-party JavaScript code. Even infected authorized code won't be able to access user data entered into the form fields.
