    Thumbs up HOW TO : ModSecurity

    Install or Update to version 1.9.3 all same
    Hello,
    Open Source Web Application Firewall
    ModSecurity at work

    ModSecurity is an open source intrusion detection and prevention engine for web applications (or a web application firewall). Operating as an Apache Web server module or standalone, the purpose of ModSecurity is to increase web application security, protecting web applications from known and unknown attacks.


    Apache 1.x
    Code:
    wget http://www.web4host.net/tools/modsecurity-apache1.sh
    chmod 755 modsecurity-apache1.sh
    sh modsecurity-apache1.sh

    Apache 2.x
    Code:
    wget http://www.web4host.net/tools/modsecurity-apache2.sh
    chmod 755 modsecurity-apache2.sh
    sh modsecurity-apache2.sh

    edit httpd.conf
    Code:
    nano -w /etc/httpd/conf/httpd.conf
    find mod_security then past this after

    Code:
    <IfModule mod_security.c>
    # Only inspect dynamic requests
    # (YOU MUST TEST TO MAKE SURE IT WORKS AS EXPECTED)
    #SecFilterEngine DynamicOnly
    
    SecFilterEngine On
    
    # Reject requests with status 500
    SecFilterDefaultAction "deny,log,status:500"
    
    # Some sane defaults
    SecFilterScanPOST On
    SecFilterCheckURLEncoding On
    SecFilterCheckCookieFormat On
    SecFilterCheckUnicodeEncoding Off
    SecFilterNormalizeCookies On
    # enable version 1 (RFC 2965) cookies
    SecFilterCookieFormat 1
    
    SecServerResponseToken Off
    
    #If you want to scan the output, uncomment these
    #SecFilterScanOutput On
    #SecFilterOutputMimeTypes "(null) text/html text/plain"
    
    # Accept almost all byte values
    SecFilterForceByteRange 1 255
    
    # Server masking is optional
    #fake server banner - NOYB used - no one needs to know what we are using
    SecServerSignature "Power MOD by web4host.net"
    
    #SecUploadDir /tmp
    #SecUploadKeepFiles Off
    
    # Only record the interesting stuff
    SecAuditEngine RelevantOnly
    SecAuditLog logs/audit_log
    
    # You normally won't need debug logging
    SecFilterDebugLevel 0
    SecFilterDebugLog logs/modsec_debug_log
    
    #Use one rules - Remove # to active Rules
    # V1.0
    #Include /etc/modsecurity/mini1.conf
    # V2.0
    #Include /etc/modsecurity/mini2.conf
    # V3.0
    #Include /etc/modsecurity/mini3.conf
    # V4.0
    #Include /etc/modsecurity/mini.conf
    # V5.0
    #Include /etc/modsecurity/mini.conf
    </IfModule>
    Search for ‘AddModule’ string, and make sure that AddModule mod_security.c

    Do a safe apache restart
    Code:
    /sbin/service httpd restart
    Remove # to active Rules (V1.0=low load / V5.0=more load)

    if you want update mini rules
    Code:
    wget http://www.web4host.net/tools/modsecurity-rule.sh
    chmod 755 modsecurity-rule.sh
    ./modsecurity-rule.sh

    If you use APF with big black list your server load gone higher then normal, use KISS and you will see stable & normal load

    Update post here in DirectAdmin Forums
    Tested in DA server

    Version 2.0.0
    March 08, 2006
    First development release of ModSecurity 2.x

    It's that time of year again, when I get to work on new features (instead of supporting the old ones). With a major change to the version number of the way I took the opportunity to introduce major improvements too. ModSecurity 2.0.0-dev1 is available right now and it offers the following major improvements:

    * Transaction scoring.
    * IP address tracking and blacklisting.
    * IP address scoring.
    * RPC API.
    * Functions (e.g. you are no longer confined to using only regular expressions in rules).
    * Real-time Black List (RBL) support.
    * Completely re-written response buffering code. It is now more robust, consumes less memory, and able to put a limit on the response size.

    The new features are properly documented so you shouldn't have any problems trying them out. I will follow up on some of them here, to explain why I think they will change how you view ModSecurity.

    P.S. There is no support for Apache 1.x in this development release.

    it doesn't work cause the script expects you to have DirectAdmin installed

    Code:

    For CentOS 5.x, RHEL 5.x, and some Fedora the install is very simple.

    # cd /tmp
    # wget http://entomy.com/epel-release-5-4.noarch.rpm
    # rpm -ivh epel-release-5-4.noarch.rpm
    # yum install mod_security
    # /etc/rc.d/init.d/httpd restart


    Mod_security is now installed & running with the default configuration, which normally works fine. If you wish to modify the configuration for some reason, edit the following file.

    /etc/httpd/modsecurity.d/modsecurity_crs_10_config.conf

    If you edit that file you will need to restart httpd again to apply changes.

    Check the post just before yours. I posted the latest for Centos 5.x and RHEL 5.x. Should work fine.
