Tutorial ini menggunakan sistem operasi linux fedora core 12 dan versi terbaru dari apache: httpd-2.2.15.tar.bz2, php: php-5.3.2.tar.bz2, modsecurity: modsecurity-apache_2.5.12.tar.gz, modsecurity core rules: modsecurity-crs_2.0.6.tar.gz

instalasi apache:
hapus apache bawaan fedora core 12
$ rpm -qa |grep httpd

httpd-tools-2.2.13-4.fc12.i686
httpd-2.2.13-4.fc12.i686

$ rpm -e gnome-user-share httpd httpd-tools

download apache terbaru
$ wget http://apache.the.net.id/httpd/httpd-2.2.15.tar.bz2
$ tar xjfv httpd-2.2.15.tar.bz2
$ cd httpd-2.2.15

Untuk menyamarkan web server yang dipakai (security in obscurity):

$ cd httpd-2.2.15/include
$ vi ap_release.h

#define AP_SERVER_BASEVENDOR “Apache Software Foundation” -> #define AP_SERVER_BASEVENDOR “software inc.”
#define AP_SERVER_BASEPRODUCT “Apache” -> #define AP_SERVER_BASEPRODUCT “webserv”

save and exit vi dengan perintah :wq
$ cd ..

$ ./configure –-prefix=/usr/local/apache2 –enable-so –enable-ssl –with-ldap –enable-ldap –enable-auth-ldap –disable-info –disable-status –disable-autoindex –disable-imap –disable-include –disable-userdir –enable-rewrite –enable-unique-id

$ make
$ make install
$ cat /etc/passwd |grep apache

jika ditemukan apache:

$vi /usr/local/apache2/conf/httpd.conf

ganti User dan Group daemon menjadi:

User apache
Group apache

save and exit vi

instalasi modsecurity:
$ wget http://nchc.dl.sourceforge.net/project/mod-security/modsecurity-apache/2.5.12/modsecurity-apache_2.5.12.tar.gz
$ tar xzfv modsecurity-apache_2.5.12.tar.gz
$ cd modsecurity-apache_2.5.12/apache2
$ ./configure –with-apxs=/usr/local/apache2/bin/apxs

terjadi error sebagai berikut :

$ wget ftp://fr2.rpmfind.net/linux/fedora/releases/12/Everything/i386/os/Packages/pcre-devel-7.8-3.fc12.i686.rpm
$ rpm -ivh pcre-devel-7.8-3.fc12.i686.rpm

$ make
$ make install

$ vi httpd.conf
tambahkan baris-baris berikut :

LoadFile /usr/lib/libxml2.so
LoadFile /usr/lib/liblua-5.1.so
LoadModule security2_module modules/mod_security2.so

save and exit vi
instalasi modsecurity core rules :

$ cd /usr/local/apache2
$ wget http://nchc.dl.sourceforge.net/project/mod-security/modsecurity-crs/0-CURRENT/modsecurity-crs_2.0.6.tar.gz
$ tar xzfv modsecurity-crs_2.0.6.tar.gz
$ mv modsecurity-crs_2.0.6 modsecurity-crs
$ vi httpd.conf
tambahkan baris-baris berikut :

Include conf/modsecurity-crs/*.conf
Include conf/modsecurity-crs/base_rules/*.conf

save and exit vi

membuat startup script untuk apache :

$ vi /etc/rc.d/init.d/httpd2

tambahkan baris-baris berikut :

*)
echo “Usage: $0 {start|stop|restart}”
exit 1
esac
exit 0

save and exit vi

$ chkconfig –add httpd2
$ service httpd2 start

DirectoryIndex index.php index.html

save and exit vi

$ service apache2 restart
$ cd /usr/local/apache2/conf/modsecurity-crs/base_rules
$ vi modsecurity_crs_50_outbound.conf

untuk menampilkan nomor baris pada vi berikan perintah :set number lalu cari baris 85 seperti berikut:

SecRule RESPONSE_BODY “!@pmFromFile modsecurity_50_outbound.data” \
“phase:4,rev:’2.0.6′,t:none,capture,t:urlDecodeUni,t:htmlEntityDecode,nolog,skipAfter:END_OUTBOUND_CHECK”

lalu edit menjadi :

SecRule RESPONSE_BODY “!@pmFromFile modsecurity_50_outbound.data” \
“phase:4,rev:’2.0.6′,t:none,capture,t:urlDecodeUni,t:htmlEntityDecode,pass,nolog,skipAfter:END_OUTBOUND_CHECK”

save and exit vi

$ cd /usr/local/apache2/conf/modsecurity-crs/
$ vi modsecurity_crs_10_config.conf

SecDefaultAction “phase:2,deny”

SecRuleEngine On

SecAuditEngine RelevantOnly
SecUploadDir /var/log/modsecurity/SecUploadDir
SecAuditLog /var/log/modsecurity/modsec_audit.log
SecAuditLogParts ABIFHZ
SecAuditLogStorageDir /var/log/modsecurity/SecAuditLogStorageDir
SecDebugLog /var/log/modsecurity/modsec_debug.log
SecDataDir /var/log/modsecurity/SecDataDir
SecTmpDir /var/log/modsecurity/SecTmpDir
SecDebugLogLevel 3

save and exit vi

$ mkdir /var/log/modsecurity
$ mkdir /var/log/modsecurity/SecTmpDir
$ mkdir /var/log/modsecurity/SecDataDir
$ mkdir /var/log/modsecurity/SecUploadDir
$ chown -R apache.apache /var/log/modsecurity
$ service apache2 restart

test instalasi dengan :

$ vi ls /usr/local/apache2/htdocs/test.php

<?php
echo “testing”;
?>

save and exit vi
dari browser panggil http://192.168.5.18/test.php. jika instalasi berhasil maka akan muncul testing
