계: Encapsulation

캡슐화는 강력한 경계를 그리는 것입니다. 웹 브라우저에서는 사용자의 모바일 코드가 다른 모바일 코드에 의해 오용되지 않도록 하는 것을 의미합니다. 서버에서는 검증된 데이터와 검증되지 않은 데이터, 한 사용자의 데이터와 다른 사용자의 데이터, 데이터 사용자가 볼 수 있는 데이터와 볼 수 없는 데이터 간의 차별화를 의미할 수 있습니다.

System Information Leak: SignalR Exposed JavaScript Proxy

C#/VB.NET/ASP.NET

Abstract

자동으로 생성된 JavaScript 프록시 파일은 허브에서 노출된 모든 메서드를 나열하기 때문에 시스템 정보가 누출될 수 있습니다.

Explanation

각 사용자의 JavaScript 프록시 파일에 모든 허브 및 메서드를 포함해야 하는 것이 아니라면 파일 자동 생성을 비활성화할 수 있습니다. 다수의 허브 및 메서드가 있지만 모든 사용자에게 전체 메서드를 알리지 않아도 되는 경우 이 옵션을 선택할 수 있습니다.
