&lt;br /&gt;&lt;/div&gt;
&lt;div&gt;&lt;b&gt;&lt;span style=&quot;font-size: 14pt; &quot;&gt;사용자 생성 및 계정 관리&lt;/span&gt;&lt;br /&gt;
&lt;br /&gt;리눅스 내부 명령어&lt;/b&gt; : 셀에 내장되어 있는 명령어로 셀이 명령어를 이해한다.&lt;/div&gt;
&lt;div&gt;&lt;br /&gt;
&lt;/div&gt;&lt;div&gt;
&lt;b&gt;리눅스 외부 명령어&lt;/b&gt; : /bin 안에 파일의 형태로 존재&lt;/div&gt;
&lt;div&gt;&lt;br /&gt;
&lt;/div&gt;&lt;div&gt;
&lt;font color=&quot;#5c7fb0&quot;&gt;차이점 : 내부 명령어의 실행 시 별도의 프로세서를 시작시키지 않지만, 외부 명령어의 실행 시 새로운 서브 프로세서를 fork하고 실행&lt;/font&gt;&lt;/div&gt;
&lt;div&gt;&lt;br /&gt;
&lt;/div&gt;&lt;div&gt;
&lt;br /&gt;&lt;/div&gt;
&lt;div&gt;&lt;b&gt;&lt;span style=&quot;font-size: 12pt; &quot;&gt;&lt;span style=&quot;font-size: 14pt; &quot;&gt;검색 경로 지정&lt;/span&gt;&lt;/span&gt;&lt;/b&gt;&lt;/div&gt;
&lt;div&gt;&lt;br /&gt;
&lt;/div&gt;&lt;div&gt;
리눅스에서 명령어는 셀이 특정 검색 경로를 찾아 실행하게 되어 있다.&lt;/div&gt;
&lt;div&gt;&lt;br /&gt;
&lt;/div&gt;&lt;div&gt;
검색경로가 지정되어 있는 파일 : &lt;b&gt;.bash_profile&lt;/b&gt;&lt;/div&gt;
&lt;div&gt;&lt;br /&gt;
&lt;/div&gt;&lt;div&gt;
&lt;b&gt;PATH = _______: _______:&lt;/b&gt;&lt;/div&gt;
&lt;div&gt;&lt;br /&gt;
&lt;/div&gt;&lt;div&gt;
&lt;font color=&quot;#5c7fb0&quot;&gt;path에 지정된 경로에 자주 사용하는 명령어의 결로를 앞쪽에 두는 것이 좋다. path에 설정된 경로를 찾을 때까지 앞에서 뒤쪽으로 차례대로 검색&lt;/font&gt;&lt;/div&gt;
&lt;div&gt;&lt;br /&gt;
&lt;/div&gt;&lt;div&gt;
&lt;b&gt;/etc/default/useradd&lt;/b&gt; : 사용자의 기본적인 셀 환경을 설정할 수 있음.&lt;/div&gt;
&lt;div&gt;&lt;br /&gt;
&lt;/div&gt;&lt;div&gt;
&lt;br /&gt;&lt;/div&gt;
&lt;div&gt;&lt;b&gt;&lt;span style=&quot;font-size: 14pt; &quot;&gt;계정 조회&lt;/span&gt;&lt;/b&gt;&lt;/div&gt;
&lt;div&gt;&lt;br /&gt;
&lt;/div&gt;&lt;div&gt;
&lt;b&gt;users&lt;/b&gt;&lt;/div&gt;
&lt;div&gt;&lt;br /&gt;
&lt;/div&gt;&lt;div&gt;
현재 시스템에 로그인된 사용자 계정을 조회 / 사용자 계정에 대한 정보를 확인&lt;/div&gt;
&lt;div&gt;&lt;br /&gt;
&lt;/div&gt;&lt;div&gt;
&amp;nbsp; &amp;nbsp; &amp;nbsp; &amp;nbsp; &amp;nbsp; &lt;b&gt;cat –n /etc/passwd&lt;/b&gt;&lt;/div&gt;
&lt;div&gt;&lt;br /&gt;
&lt;/div&gt;&lt;div&gt;

&amp;nbsp;&lt;/div&gt;
&lt;div&gt;&lt;br /&gt;
&lt;/div&gt;&lt;div&gt;
&amp;nbsp;&lt;/div&gt;
&lt;div&gt;&lt;br /&gt;

&lt;a href=&quot;http://alieneyes.wordpress.com/2006/10/23/how-to-gain-access-to-system-account-the-most-powerful-account-in-windows/&quot;&gt;http://alieneyes.wordpress.com/2006/10/23/how-to-gain-access-to-system-account-the-most-powerful-account-in-windows/&lt;/a&gt;&amp;nbsp;&lt;br /&gt;
&lt;br /&gt;
Microsoft Windows 운영체제에는 Aministrator 계정보다 강력한 권한을 가지는 System 계정이 있습니다.&lt;br /&gt;
&lt;br /&gt;
Windows 의 System 계정은 Linux/Unix 운영체제의 root 계정과 비슷합니다.&amp;nbsp;&lt;br /&gt;
&lt;br /&gt;
프로그램을 삭제할 때 권한 문제로 삭제가 되지 않는다면, System 계정으로 로그인하여 프로그램을 삭제할 수 있습니다.&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
1. 명령창을 실행합니다. (&lt;b&gt;시작 -&amp;gt; 실행 -&amp;gt;&amp;nbsp;&quot;cmd&quot; &amp;nbsp;-&amp;gt; [Enter]&lt;/b&gt;)&lt;br /&gt;
&lt;br /&gt;
2. 로그인한 계정명을 확인합니다.&amp;nbsp;(&lt;b&gt;whoami&lt;/b&gt;)&lt;br /&gt;
&lt;p style=&quot;margin:0&quot;&gt;&lt;div class=&quot;imageblock center&quot; style=&quot;text-align: center; clear: both;&quot;&gt;&lt;a href=&quot;http://cfile23.uf.tistory.com/original/1659E9354F20E4831DDCE7&quot; rel=&quot;lightbox&quot; target=&quot;_blank&quot;&gt;&lt;img src=&quot;http://cfile23.uf.tistory.com/image/1659E9354F20E4831DDCE7&quot; alt=&quot;&quot; filemime=&quot;image/jpeg&quot; filename=&quot;img29.png&quot; height=&quot;431&quot; width=&quot;668&quot;/&gt;&lt;/a&gt;&lt;/div&gt;&lt;/p&gt;
&lt;br /&gt;
&lt;br /&gt;
3. 명령창에 cmd.exe 를 실행하는 스케쥴을 생성합니다. 다음과 같이 입력하고 [Enter] 합니다. 시간 부분은 실행 예정 시간이므로 적절히 입력합니다.&lt;br /&gt;
&lt;b&gt;at 14:30 /interactive &quot;cmd.exe&quot;&lt;br /&gt;
&lt;p style=&quot;margin:0&quot;&gt;&lt;br /&gt;
&lt;/p&gt;
&lt;p style=&quot;margin:0&quot;&gt;&lt;div class=&quot;imageblock center&quot; style=&quot;text-align: center; clear: both;&quot;&gt;&lt;a href=&quot;http://cfile25.uf.tistory.com/original/1244E0484F20E5182AB791&quot; rel=&quot;lightbox&quot; target=&quot;_blank&quot;&gt;&lt;img src=&quot;http://cfile25.uf.tistory.com/image/1244E0484F20E5182AB791&quot; alt=&quot;&quot; filemime=&quot;image/jpeg&quot; filename=&quot;img30.png&quot; height=&quot;431&quot; width=&quot;668&quot;/&gt;&lt;/a&gt;&lt;/div&gt;&lt;/p&gt;
&amp;nbsp;&lt;/b&gt;&lt;br /&gt;
&lt;br /&gt;
4. 스케쥴러에 등록한 스케쥴 시간까지 기다리면 자동으로 명령창이 실행됩니다. 명령창이 실행되면 &lt;b&gt;whoami &lt;/b&gt;명령을 통해 현재 계정을 확인합니다.&lt;br /&gt;
&lt;p style=&quot;margin:0&quot;&gt;&lt;div class=&quot;imageblock center&quot; style=&quot;text-align: center; clear: both;&quot;&gt;&lt;a href=&quot;http://cfile29.uf.tistory.com/original/1344E0484F20E5182BF689&quot; rel=&quot;lightbox&quot; target=&quot;_blank&quot;&gt;&lt;img src=&quot;http://cfile29.uf.tistory.com/image/1344E0484F20E5182BF689&quot; alt=&quot;&quot; filemime=&quot;image/jpeg&quot; filename=&quot;img31.png&quot; height=&quot;431&quot; width=&quot;668&quot;/&gt;&lt;/a&gt;&lt;/div&gt;&lt;/p&gt;
&lt;br /&gt;
&lt;br /&gt;
5. cmd.exe 가 스케쥴러에 의해 실행되면, &lt;b&gt;[CTRL] + [ALT] + [DEL]&lt;/b&gt; 키를 눌러서 작업관리자 창을 열어줍니다.&lt;br /&gt;
&lt;br /&gt;
6. &lt;b&gt;explorer.exe 프로세스를 선택&lt;/b&gt;하고 &lt;b&gt;프로세스 끝내기 버튼&lt;/b&gt;을 눌러줍니다. 이 때 데스크탑 바탕화면의 시작 메뉴 바가 사라집니다.&lt;br /&gt;
&lt;p style=&quot;margin:0&quot;&gt;&lt;div class=&quot;imageblock center&quot; style=&quot;text-align: center; clear: both;&quot;&gt;&lt;a href=&quot;http://cfile5.uf.tistory.com/original/2065983B4F20E5E82708A1&quot; rel=&quot;lightbox&quot; target=&quot;_blank&quot;&gt;&lt;img src=&quot;http://cfile5.uf.tistory.com/image/2065983B4F20E5E82708A1&quot; alt=&quot;&quot; filemime=&quot;image/jpeg&quot; filename=&quot;img32.png&quot; height=&quot;576&quot; width=&quot;679&quot;/&gt;&lt;/a&gt;&lt;/div&gt;&lt;/p&gt;
&lt;br /&gt;
&lt;br /&gt;
7. 처음에 열린 cmd 창을 닫아줍니다.(이때 &lt;b&gt;두번째 열린 cmd 창을 닫지 않도록 주의&lt;/b&gt;합니다.)&lt;br /&gt;
&lt;br /&gt;
8. 프롬프트에 &lt;b&gt;cd .. &lt;/b&gt;을 입력하여 상위 폴더로 이동합니다.&lt;br /&gt;
&lt;br /&gt;
9. &amp;nbsp;&lt;b&gt;explorer.exe&lt;/b&gt; 를 입력하고 [Enter] 합니다.&lt;br /&gt;
&lt;br /&gt;
10. System 계정의 데스크탑환경으로 전환됩니다.&amp;nbsp;&lt;br /&gt;
&lt;br /&gt;
&lt;b&gt;&lt;font color=&quot;#c84205&quot;&gt;system 파일을 삭제하거나 수정할 경우 PC 운용에 치명적인 문제가 발생할 수 있으므로, 신중하게 작업하기 바랍니다.&lt;/font&gt;&lt;/b&gt;&lt;br /&gt;
&lt;br /&gt;
&lt;font color=&quot;#193da9&quot;&gt;Tip : 스케쥴러 목록에 등록한 cmd.exe &amp;nbsp;스케쥴은 다음과 같은 명령어로 삭제가 가능합니다. &lt;br /&gt;
&lt;b&gt;at /delete /yes&lt;/b&gt; (모든 스케쥴 삭제)&lt;/font&gt;&lt;br /&gt;
&lt;br /&gt;

fail2ban을 설치해 보았지만 제대로 동작하지 않은것 같아서 아래 방법을 시도해 보려고 한다.&lt;br /&gt;
&lt;br /&gt;&lt;a href=&quot;http://cafe.naver.com/linuxihd.cafe?iframe_url=/ArticleRead.nhn%3Farticleid=238&amp;amp;&quot;&gt;참조 :&amp;nbsp;&lt;a href=&quot;http://cafe.naver.com/linuxihd.cafe?iframe_url=/ArticleRead.nhn%3Farticleid=238&amp;amp;&quot; target=&quot;_blank&quot; title=&quot;[http://cafe.naver.com/linuxihd.cafe?iframe_url=/ArticleRead.nhn%3Farticleid=238&amp;amp;]로 이동합니다.&quot;&gt;http://cafe.naver.com/linuxihd.cafe?iframe_url=/ArticleRead.nhn%3Farticleid=238&amp;amp;&lt;/a&gt;&lt;/a&gt;&amp;nbsp;&lt;br /&gt;
&lt;br /&gt;Brute-force attack은 패스워드 사전 파일을 이용하여 미리 지정한 아이디를 지속적으로 대입하여 취약한 패스워드로 설정된 ID를 찾는 공격이며, iptables를 이용하여 간단하게 막는 방법을 다음과 같이 소개합니다.&lt;br /&gt;
&lt;br /&gt;===========&lt;br /&gt;
%-A INPUT -p tcp --dport 22 -m state --state NEW -m recent --set --name SSHSCAN&lt;br /&gt;
%-A INPUT -p tcp --dport 21 -m state --state NEW -m recent --set --name FTPSCAN&lt;br /&gt;
%-A INPUT -p tcp --dport 22 -m state --state NEW -m recent --update --seconds 60 --hitcount 10 --rttl --name SSHSCAN -j LOG --log-prefix SSH_Scan:&lt;br /&gt;
%-A INPUT -p tcp --dport 21 -m state --state NEW -m recent --update --seconds 60 --hitcount 10 --rttl --name FTPSCAN -j LOG --log-prefix FTP_Scan:&lt;br /&gt;
%-A INPUT -p tcp --dport 22 -m state --state NEW -m recent --update --seconds 60 --hitcount 10 --rttl --name SSHSCAN -j DROP&lt;br /&gt;
%-A INPUT -p tcp --dport 21 -m state --state NEW -m recent --update --seconds 60 --hitcount 10 --rttl --name FTPSCAN -j DROP&lt;br /&gt;
===============&lt;br /&gt;
&lt;br /&gt;위의 스크립트는 ssh 또는 ftp brute force attack 공격을 받을 경우 60초간 9번의 로그인 실패시 10번째부터 60초간 접속을 막는 방법입니다. 또 다른 방법으로는 1234, abcd 와 같은 쉬운 패스워드보다 특수문자를 이용한 강력한 패스워드로 설정합니다. 해킹당한 서버의 대부분은 이렇게 유추하기 쉬운 패스워드로 지정되어 있는 경우가 가장 많습니다.&lt;br /&gt;
&lt;br /&gt;마지막으로 ssh 접속 포트를 변경하는 것도 좋은 방법입니다.&lt;br /&gt;
/etc/ssh/sshd_config의 #port 22 항목의 주석을 제거하고 22번을 다른 포트 번호로 변경 후 지정합니다.&lt;br /&gt;
/etc/rc.d/init/sshd restart를 입력 후 변경한 포트로 접속이 되는지 확인하시기 바랍니다.&lt;br /&gt;
&lt;br /&gt;oops-firewall/user.conf 파이을 이용하여 적용도 가능합니다.&lt;br /&gt;
/var/log/messages, secure 파일에서 ftp 혹은 ssh 로 검색하여 보면 접속 실패 메시지가 많이 나오는 분들은 꼭 위의 스크립트로 막아주신다면 더 좋은 보안환경을 만들 수 있을 것 같습니다.&lt;br /&gt;
&lt;br /&gt;&lt;br /&gt;
ps. 집에가서 적용해 봐야지.&amp;nbsp;&lt;div class=&quot;entry-ccl&quot; style=&quot;clear: both; text-align: right; margin-bottom: 10px&quot;&gt;
