Client-side web security

Obviously, enterprise teams should integrate client-side protections with desired server-side countermeasures to ensure a full risk management profile (e.g., the client-side is a poor selection point to stop denial of service).

Several standards-based client-side security approaches have begun to mature that are worth examining from the perspective of website security and protection of browser sessions from malicious exploits. The best client-side security platforms automate implementation of these standards-based controls with emphasis on simplicity of administration. A typical, representative platform is used to demonstrate necessary client-side security controls.

Content security policy

To understand client-side security platforms, it helps to first explore the specifics of a standard approach known as a content security policy (CSP). This is a standard that is designed to address several types of web breaches such as cross-site scripting, click-jacking and form-jacking (all described earlier in this article series). CSP is also designed to reduce the risk of client-side malware injected from an infected advertising ecosystem.
