Content Security Policy

Content Security Policy

1. Introduction

This Content Security Policy (CSP) document establishes the security guidelines for content delivered from {{company_name}}'s web properties. Its primary purpose is to mitigate vulnerabilities such as Cross-Site Scripting (XSS), data injection, and other content-related attacks.

All employees, contractors, and third-party vendors who develop, maintain, or publish content on behalf of {{company_name}} are required to adhere to the directives outlined in this policy.

2. Policy Objectives

The objectives of this CSP are to:

a) Minimize the risk of XSS attacks by restricting the sources from which content can be loaded.

b) Protect users from malicious content and unauthorized data access.

c) Ensure the integrity and authenticity of content delivered by {{company_name}}'s web applications.

d) Provide a robust security framework for all web-based operations.

3. Scope

This policy applies to all web applications, websites, and content delivery platforms owned, managed, or used by {{company_name}}.

It covers all forms of content, including but not limited to HTML, CSS, JavaScript, images, fonts, media, and web workers.

4. CSP Directives

The following CSP directives will be implemented:

default-src: Specifies the default source list for various content types, acting as a fallback for any content types not explicitly listed.

script-src: Defines valid sources of JavaScript. Only scripts from {{trusted_script_sources}} are permitted.

style-src: Specifies valid sources of stylesheets. Only stylesheets from {{trusted_style_sources}} are permitted.

img-src: Defines valid sources of images. Only images from {{trusted_image_sources}} are permitted.

connect-src: Restricts the URLs that can be loaded using script interfaces (e.g., fetch, XMLHttpRequest, WebSockets). Only connections to {{trusted_data_sources}} are permitted.

font-src: Specifies valid sources for fonts. Only fonts from {{trusted_font_sources}} are permitted.

object-src: Defines valid sources for plugins like <object>, <embed>, or <applet>. These elements will be restricted to {{trusted_object_sources}} or blocked if not specified.

media-src: Specifies valid sources for loading media (audio, video). Only media from {{trusted_media_sources}} is permitted.

frame-src: Defines valid sources for embedding frames. Only frames from {{trusted_frame_sources}} are permitted.

frame-ancestors: Specifies valid parents that may embed a page using <frame>, <iframe>, <object>, <embed>, or <applet>.

report-uri: Specifies a URI to which the browser will send reports when a content security policy is violated. Reports will be sent to {{csp_report_uri}}.

5. Implementation Guidelines

CSP will be implemented via HTTP response headers for all web applications. The header will be configured as 'Content-Security-Policy: [directives]'.

All content requiring exceptions to the standard directives must be explicitly reviewed and approved by the IT Security Department.

Development teams are responsible for testing CSP configurations in staging environments before deployment to production.

6. Monitoring and Reporting

CSP violation reports will be automatically collected by the system and sent to {{csp_report_uri}}.

The IT Security Department will regularly review violation reports to identify potential threats or misconfigurations.

Regular audits of CSP implementation will be conducted to ensure ongoing compliance and effectiveness.

7. Policy Review

This policy will be reviewed annually or as necessitated by changes in technology, threats, or regulatory requirements.

Any updates or amendments to this policy will be communicated to all relevant stakeholders.

8. Enforcement

Non-compliance with this Content Security Policy may result in disciplinary action, up to and including termination of employment or contract, and potential legal action.

It is the responsibility of all personnel involved in web development and content management to understand and adhere to this policy.

9. Definitions

Content Security Policy (CSP): An added layer of security that helps to detect and mitigate certain types of attacks, including Cross-Site Scripting (XSS) and data injection attacks.

Cross-Site Scripting (XSS): A type of security vulnerability typically found in web applications. XSS attacks enable attackers to inject client-side scripts into web pages viewed by other users.

Directive: A keyword indicating a specific type of content that the CSP applies to (e.g., script-src, img-src).

Source List: A list of allowed origins from which content can be loaded for a given directive.
