In one aspect, this comprises embedding a nonce and a script in all responses from the server to the client wherein, when executed, the script adds the nonce to each request from the client to the server; sending the response with the nonce and the script to the client; and verifying that each request from the client includes the nonce sent by the server to the client. The script preferably modifies all objects, including dynamically generated objects, in a server response that may generate future requests to the server to add the nonce to the requests. The server verifies the nonce value in a request and optionally confirms the request with the client if the value differs from the value previously sent. Server-side aspects might be embodied in the server or a proxy."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Preventing cross-site request forgery attacks on a server","description":"Preventing Cross-Site Request Forgery security attacks on a server in a client-server environment.
