  • ModSecurity - ubuntu server 12.10 X64 Problem

    سلام

    من یک سرور در یک شبکه راه اندازی کردم وبعدش هم طبق راهنمای زیر modsecurity رو نصب کردم :
    http://www.root25.com/2012/11/how-to...-tutorial.html

    وقتی کاملا نصب شد :
    SecRuleEngine On قرار دادم و سپس با acunetix تست زدم ولی تا اومد شروع به کار کنه ارور ۴۰۳ داد و صفحه forbiden شد نه تنها برای خودم بلکه برای همه و هر کسی که می خواسا وارد سایت بشه و بازدید کنه !!!
    SecRuleEngine DetectOnly گذاشتم و با acunrtix تست کردم و همه چی باز و اسکن میشد و ... انگار نه انگار که modsecurity نصب و کانفیگ شده !! حالا سوال من اینه که چطور میتونم کاری کنم که On باشه و فقط کسی که داره اسکن می کنه و یا قصد ... داره بلاک بشه .


    ممنون میشم راهنمایی کنید.
    این هم کافیگ :

    # -- Rule engine initialization ----------------------------------------------

    # disruption.

    SecRuleEngine DetectionOnly
    #SecRuleEngine On
    SecRule REQUEST_URI attack
    # -- Request body handling ---------------------------------------------------
    # Allow ModSecurity to access request bodies. If you don't, ModSecurity
    # won't be able to see any POST parameters, which opens a large security
    # hole for attackers to exploit.

    # low as practical.

    # Store up to 128 KB of request body data in memory. When the multipart
    # parser reachers this limit, it will start using your hard disk for
    # storage. That is slow, but unavoidable.
    #
    SecRequestBodyInMemoryLimit 131072

    # What do do if the request body size is above our configured limit.
    # Keep in mind that this setting will automatically be set to ProcessPartial
    # when SecRuleEngine is set to DetectionOnly mode in order to minimize
    # disruptions when initially deploying ModSecurity.

    # Verify that we've correctly processed the request body.

    # -- Response body handling --------------------------------------------------

    # Allow ModSecurity to access response bodies.
    # You should have this directive enabled in order to identify errors
    # and data leakage issues.
    #
    # Do keep in mind that enabling this directive does increases both
    # memory consumption and response latency.
    #
    SecResponseBodyAccess On
    # Which response MIME types do you want to inspect? You should adjust the
    # configuration below to catch documents but avoid static files
    # (e.g., images and archives).

    SecResponseBodyMimeType text/plain text/html text/xml

    # Buffer response bodies of up to 512 KB in length.
    SecResponseBodyLimit 524288

    # What happens when we encounter a response body larger than the configured
    # limit? By default, we process what we have and let the rest through.
    # That's somewhat less secure, but does not break any legitimate pages.
    #
    SecResponseBodyLimitAction ProcessPartial


    # -- Filesystem configuration ------------------------------------------------

    # The location where ModSecurity stores temporary files (for example, when
    # it needs to handle a file upload that is larger than the configured limit).
    #
    # This default setting is chosen due to all systems have /tmp available however,
    # this is less than ideal. It is recommended that you specify a location that's private.
    #
    SecTmpDir /tmp/

    # The location where ModSecurity will keep its persistent data. This default setting
    # is chosen due to all systems have /tmp available however, it
    # too should be updated to a place that other users can't access.
    #
    SecDataDir /tmp/


    # -- File uploads handling configuration -------------------------------------

    # The location where ModSecurity stores intercepted uploaded files. This
    # location must be private to ModSecurity. You don't want other users on
    # the server to access the files, do you?
    #
    #SecUploadDir /opt/modsecurity/var/upload/

    # By default, only keep the files that were determined to be unusual
    # in some way (by an external inspection ******). For this to work you
    # will also need at least one file inspection rule.
    #
    #SecUploadKeepFiles RelevantOnly

    # Uploaded files are by default created with permissions that do not allow
    # any other user to access them. You may need to relax that if you want to
    # interface ModSecurity to an external program (e.g., an anti-virus).
    #
    #SecUploadFileMode 0600


    # -- Debug log configuration -------------------------------------------------

    # The default debug log configuration is to duplicate the error, warning
    # and notice messages from the error log.
    #
    #SecDebugLog /opt/modsecurity/var/log/debug.log
    SecDebugLogLevel 3


    # -- Audit log configuration -------------------------------------------------

    # Log the transactions that are marked by a rule, as well as those that
    # trigger a server error (determined by a 5xx or 4xx, excluding 404,
    # level response status codes).
    #
    #SecAuditEngine RelevantOnly
    SecAuditEngine On
    SecAuditLogRelevantStatus "^(?:5|4(?!04))"

    # Log everything we know about a transaction.
    SecAuditLogParts ABIJDEFHZ

    # Use a single file for logging. This is much easier to look at, but
    # assumes that you will use the audit log only ocassionally.
    #
    SecAuditLogType Serial
    SecAuditLog /var/log/apache2/modsec_audit.log

    # Specify the path for concurrent audit logging.
    #SecAuditLogStorageDir /opt/modsecurity/var/audit/


    # -- Miscellaneous -----------------------------------------------------------

    # Use the most commonly used application/x-www-form-urlencoded parameter
    # separator. There's probably only one application somewhere that uses
    # something else so don't expect to change this value.
    #
    SecArgumentSeparator &

    # Settle on version 0 (zero) ****ies, as that is what most applications
    # use. Using an incorrect ****ie version may open your installation to
    # evasion attacks (against the rules that examine named ****ies).
    #
    Sec****ieFormat 0
    #
    # Stop Layer 7 Slow Request Attacks

      هميشه راهي براي نفوذ است و هيچ سيستمي به طور مطلق امن نيست. بلكه بايستي آن راه نفوذ را كشف كرد .هنر هك هم در همين نكته متبلور ميشود
