# Chapter 2. Access Control

이 챕터에서는 안녕 리눅스의 **ACL(Access Control List)**에 대해서 기술 합니다.

**ACL(Access Control List)**이라는 단어는 보통은 Network 관련하여 접근제어를 할 때 많이 사용하는 단어 입니다. 대부분 IP 기반에서 많이 사용하지만 IP base 외에도 account base의 ACL도 가능 합니다.

여기서는 안녕 리눅스를 이용하여 다양한 **ACL(Access Control List)** 설정 기법에 대해서 기술 합니다.

안녕 리눅스의 **ACL(Access Control List)**의 특징 중의 하나는 국가/ISP base의 control에 대해서 적극적으로 지원을 한다는 점입니다.
