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.

Android Bad Practices: Encryption Secret Held in Static Field

Java/JSP

Abstract

응용 프로그램이 정적 클래스 필드에 암호화 키를 유지하며, 이로 인해 공격자가 암호화 키를 쉽게 복구할 수 있습니다.

Explanation

암호화 키를 정적 클래스 필드에 저장하면 프로세스 메모리(예: 루팅된 장치) 또는 프로세스 메모리 덤프(예: 크래시 덤프)에 액세스할 수 있는 엔터티가 쉽게 복구할 수 있습니다.
