Maybe try the following? · Make sure the modsecurity_crs_11_brute_force.conf is loading properly . Maybe you have made a mistake with symbolic link or putting the file in wrong folder. · Make sure you have uncommented the brute force rule in modsecurity_crs_10_setup.conf (By default it is commented out) · Maybe try changing your URL to include your actual web login file?

I tried it, its not working for me. I used the value like that but when i do brute force attempt in the web application with random username and password it gives me nothing in the mod audit log. I'm using burp suit pro intruder for testing. Have you tried it besides wordpress? Wonder what I'm doing wrong. thanks anyway. cheers On Thu, Aug 21, 2014 at 11:43 PM, Wesley Render <wren...@otherdata.com<mailto:wren...@otherdata.com>> wrote: I believe you would just set yours like this (Just include the URL after the domain name)…. # # -- [[ Brute Force Protection ]] --------------------------------------------------------- # # If you are using the Brute Force Protection rule set, then uncomment the following # lines and set the following variables: # - Protected URLs: resources to protect (e.g. login pages) - set to your login page # - Burst Time Slice Interval: time interval window to monitor for bursts # - Request Threshold: request # threshold to trigger a burst # - Block Period: temporary block timeout # SecAction \ "id:'900014', \ phase:1, \ t:none, \ setvar:'tx.brute_force_protected_urls=#/user/user/login/#', \ setvar:'tx.brute_force_burst_time_slice=60', \ setvar:'tx.brute_force_counter_threshold=10', \ setvar:'tx.brute_force_block_timeout=300', \ nolog, \ pass" [Otherdata_Logo_2011] Wesley Render, IT Consultant, RHCSA Phone: 1.403.228.1221 ext 201<tel:1.403.228.1221%20ext%20201> www.otherdata.com<http://www.otherdata.com/> [findonfacebook]<http://www.facebook.com/otherdata> From: Sabin Ranjit [mailto:think.sa...@gmail.com<mailto:think.sa...@gmail.com>] Sent: August-21-14 10:39 AM To: Wesley Render Cc: owasp-modsecurity-core-rule-set@lists.owasp.org<mailto:owasp-modsecurity-core-rule-set@lists.owasp.org> Subject: Re: [Owasp-modsecurity-core-rule-set] crs against brute force not working hi Wesley, I'm not using wordpress, I'm try to protect my application made in Yii framework and its login url looks like this: https://domainname.net/user/user/login/ how can I set brute_force_protected_urls value for thisof url ?I tried few ways but it gave me syntax error. thanks, regards On Thu, Aug 21, 2014 at 9:36 PM, Wesley Render <wren...@otherdata.com<mailto:wren...@otherdata.com>> wrote: In your modsecurity_crs_10_setup.conf file you need to make sure to uncomment, and define the paths for your login page.
