apacheで攻撃者に有用な情報を与えない対策

Last updated at Posted at 2014-12-11

nginxの場合は Nginx導入時、サクッと対応しておくと良いかもしれない - Qiita

確認
curl -I http://url〜

Apacheのバージョンを出力させない

httpd.conf
- ServerTokens Full
+ ServerTokens Prod
  • ServerSignature OffはProdの場合不要。
curl localhost/aaa
 <!DOCTYPE HTML PUBLIC "-//IETF//DTD HTML 2.0//EN">
 <html><head>
 <title>404 Not Found</title>
 </head><body>
 <h1>Not Found</h1>
 <p>The requested URL /aaa was not found on this server.</p>
 <hr>
+<address>Apache/2.4.7 (Ubuntu) Server at localhost Port 80</address>
 </body></html>

PHPのバージョンを出力させない

php.ini
- expose_php = On
+ expose_php = Off

Apacheのwelcomeページを表示させない

cd /etc/httpd/conf.d/
mv welcome.conf welcome.conf.org

以下は今はしなくても良さそう。

IE6初期以前のBasic認証セキュリティ向上

telnet dummy.hoge.jp 80
  • OPTIONS / HTTP/1.0を入力しEnter2回。

Allow: GET,HEAD,POST,OPTIONS,TRACE

TRACEを無効にするには以下

httpd.conf
+ TraceEnable Off
