By injecting the Content-Security-Policy (CSP) headers from the server, the browser is aware and capable of protecting the user from dynamic calls that will load content into the page currently being visited.

These Concrete Surface Profiles were developed by the International Concrete Repair Institute (ICRI), are divided into ten classifications (CSP 1-10) of surface textures based on the average distance from the peaks of the surface to the valleys.

In Part I of our series on concrete surface preparation, we looked at how to detect, remove and repair unsound concrete. In Part II, we saw the different kinds of surface contaminants for concrete and how to clean them. In Part III, we look at methods for roughening the surface in preparation for the coating or overlayment.

Content-Security-Policy is the name of a HTTP response header that modern browsers use to enhance the security of the document (or web page). The Content-Security-Policy header allows you to restrict which resources (such as JavaScript, CSS, Images, etc.) can be loaded, and the URLs that they can be loaded from.

2025年3月13日 · In this guide we'll start by describing how a CSP is delivered to a browser and what it looks like at a high level. Then we'll describe how it can be used to control which resources are loaded to protect against XSS, and then other use cases such as clickjacking protection and upgrading insecure requests.

Content Security Policy （CSP）内容安全策略，是一个附加的安全层，有助于检测并缓解某些类型的攻击，包括跨站脚本（XSS）和数据注入攻击。 简单来说，csp就是为了减少xss，csrf等攻击的，是通过控制可信来源的方式，类似于同源策略… CSP以白名单的机制对网站加载或执行的资源起作用。 在网页中，这样的策略通过 HTTP 头信息或者 meta 元素定义。 CSP虽然提供了强大的安全保护，但是他也造成了如下问题：Eval及相关函数被禁用、内嵌的JavaScript代码将不会 …

Use this guide to identify the surface profile of your concrete. CSP 1 being the indicator for a nearly smooth floor and CSP 10 indicative of an extremely rough floor. The range of variation will depend on strength, composition, aggregate and finish. CSP 1-4 not recommended with cement based products.

W3C® liability, trademark and permissive document license rules apply. This document defines a mechanism by which web developers can control the resources which a particular page can fetch or execute, as well as a number of security-relevant policy decisions. This section describes the status of this document at the time of its publication.

CSP represents the measure of surface roughness. Different CSP levels, typically rated from 1 to 9, directly affect how well subsequent coatings and overlays bond to the surface. You can identify the required CSP level based on the thickness and type of the overlay or coating applied.

A strong CSP provides an effective second layer of protection against various types of vulnerabilities, especially XSS. Although CSP doesn't prevent web applications from containing vulnerabilities, it can make those vulnerabilities significantly more difficult for an attacker to exploit.
