To address attacks such as XSS, Magecart and other card skimming exploits found in modern eCommerce environments, the use of client-side web security methods is beginning to emerge as a particularly useful practice.
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.
