* 인증과 인가라는 단어가 떠올라야 한다.
* 인증? 인가?
* 예를 들어, 청와대 못들어감. 들어갈 수 있는 권한이 없다. 가겠다고 예약해서 승인-허가가 떨어지면 들어갈 수 있다. 내가 최종적으로 가고자 하는 목적지. 이를 타겟이라 부름.
* 최초에 가야할 타겟에 도착하기 까지의 모든 과정에서 인증과 인가가 완벽하게 이루어져야 한다.
* 클라이언트와 서버의 개념으로 보면, 브라우저에서 타겟으로 넘어가는데, 타겟 문 앞에서 문을 두드림. 물어보면 목적지에 해당하는 타겟 컨트롤러가 잠시 대기시키고 출입허가를 살펴봄. 여기에 해당 허용된 사용자의 이름을 확인하고 들여보내는 개념
* 스프링 프레임워크에서도 구조는 같음.

By default, no user is included in the "manager-gui" role required
to operate the "/manager/html" web application. If you wish to use this app,
you must define such a user - the username and password are arbitrary.
Built-in Tomcat manager roles:
- manager-gui - allows access to the HTML GUI and the status pages
- manager-script - allows access to the HTTP API and the status pages
- manager-jmx - allows access to the JMX proxy and the status pages
- manager-status - allows access to the status pages only
The users below are wrapped in a comment and are therefore ignored. If you
wish to configure one or more of these users for use with the manager web
application, do not forget to remove the <!.. ..> that surrounds them. You
will also need to set the passwords to something appropriate.

JSP 시큐리티 web.xml 설정
1. 시큐리티 역할 설정하는 방법
<security-role>
<role-name>role1</role-name> // 역할 이름
</security-role>
2. 시큐리티 제약사항 설정하기
<security-constraint>
<web-resource-collection></web-resource-collection> // 웹 자원에 대한 접근 설정
<auth-constraint></auth-constraint> // 웹 자원에 접근할 수 있는 인증된 사용자 설정
<user-data-constraint></user-data-constraint> // 데이터 전송 시 데이터 보호를 설정
</security-constraint>
2.1 웹 자원에 대한 접근 설정
<web-resource-collection>
<web-resource-name>JSPBookProject</web-resource-name> // 웹 자원의 이름을 설정하며 생략할 수 있다.
<url-pattern>/ch10/security02.jsp</url-pattern> // 접근 제한을 요청할 때 URL 목록을 설정
<http-method>GET</http-method> // HTTP 메소드를 설정(GET, POST)
</web-resource-collection>
2.2 웹 자원에 접근할 수 있는 인증된 사용자 설정
- auth-constraint를 설정하지 않으면 웹 서버는 사용자 인증을 요구하지 않고 사용자의 요청을 승인한다.
<auth-constraint>
<description></description> // 설명
<role-name>role1</role-name> // 반드시 tomcat-users.xml에 등록된 역할과 사용자여야 한다.
</auth-constraint>
2.3 클라이언트와 서버 간에 데이터를 전송할 때 데이터를 보호하는 방법을 설정
- NONE : 기본 값으로 데이터를 보호하지 않을 때
- INTEGRAL : 전송 중 데이터가 변경되지 않았음을 보장(데이터 무결성)
- CONFIDENTIAL : 전송 중 데이터를 아무도 훔쳐보지 않았음을 보장(데이터 기밀성)
<user-data-constraint>
<transport-guarantee>NONE</transport-guarantee>
</user-data-constraint>
3. 시큐리티 인증 설정하기
<login-config>
<auth-method>FORM</auth-method> // 웹 자원에 대한 인증 처리 방식 설정
<realm-name></realm-name> // 웹 자원에 접근할 수 있는 인증된 사용자 설정
<form-login-config></form-login-config> // 데이터 전송 시 데이터 보호를 설정
</login-config>
3-1 웹 애플리케이션의 인증 처리 기법을 설정하는 요소
- BASIC : 웹 자원을 보호하는 간단하고 일반적인 방법
- DIGEST : 암호화 메커니즘을 이용하여 전송 (많이 사용되지 않음)
- FORM : [대표적] 일반적인 폼 페이지를 이용하여 로그인 정보를 서버에 전송하는 방식
암호화 되지 않은 로그인 정보를 그대로 전송
*** FORM 기반 인증시에는 별도 form 처리가 필요하다
- CLIENT-CERT : 클라이언트가 인증서를 가지고 공인 키 인증 방식을 사용하여 로그인하는 방식
클라이언트가 인증서를 가지고 있어야만 로그인되므로 비즈니스 환경에서만 적용
<auth-method>FORM</auth-method>
3-2 기본 인증의 영역 이름을 설정
- FORM 기반 인증이나 다른 인증 방법에 필요하지 않기 때문에 아무런 영향을 미치지 않지만, 데이터를 문서화하는데 일반적으로 사용
<realm-name>영역 이름</realm-name>
3-3 인증 처리를 위한 로그인 및 오류 페이지를 설정
- auth-method 요소가 FORM 기반 인증 처리 기법으로 설정되었을 때 사용
<form-login-config>
<form-login-page>/ch10/login.jsp</form-login-page>
<form-error-page>/ch10/login_failed.jsp</form-error-page>
</form-login-config>

By default, no user is included in the "manager-gui" role required
to operate the "/manager/html" web application. If you wish to use this app,
you must define such a user - the username and password are arbitrary.
Built-in Tomcat manager roles:
- manager-gui - allows access to the HTML GUI and the status pages
- manager-script - allows access to the HTTP API and the status pages
- manager-jmx - allows access to the JMX proxy and the status pages
- manager-status - allows access to the status pages only
The users below are wrapped in a comment and are therefore ignored. If you
wish to configure one or more of these users for use with the manager web
application, do not forget to remove the <!.. ..> that surrounds them. You
will also need to set the passwords to something appropriate.

* 400 에러 발생하는 이유?
(1) 데이터 누락 : 서버로 보내야할 데이터가 5개인데 3개면 받는 개수와 보내는 개수가 다르기 때문에 나타남
(2) 타입이 다를 때 : 클라이언트로 데이터를 보낼 때 보내는 타입과 받는 타입이 다른 경우
* 데이터를 주고받는 과정에서 400 에러가 뜨는 경우는 출발지와 목적지에 따른 설정의 에러는 에러 검증을 다르게 해야 함. 클라이언트의 도착지 설정을 확인하고, 서버쪽에서도 도착지 설정을 확인해야 한다.
* 디버깅 스킬 늘려야 하고, 각각의 에러가 왜 났는지에 대한 범위를 좁혀나가야 한다.
