Mod_security has a rules updater distributed with their release packages on sourceforge:
http://sourceforge.net/projects/mod-security/files/modsecurity-crs/0-CURRENT/
Usually, you can run the script and modsec will update the rules for you. However, recently, this feature has stopped working. I get the following 404 error when I attempt to update the ruleset to 2.2.4:
$ ./rules-updater.pl -rhttp://www.modsecurity.org/autoupdate/repository -prepository/ -Smodsecurity-crs
Could not load GnuPG module - cannot verify ruleset signatures
Fetching: modsecurity-crs/modsecurity-crs_2.2.3.zip ...
Failed to retrieve ruleset modsecurity-crs/modsecurity-crs_2.2.3.zip: 404 Not Found
We have a cron job which downloads and applies the rules frequently. It's been great up till now. Has anybody found a solution to this? Is anybody aware of other free/open repositories with self-update scripts? I've searched the forums, but no luck so far. Any help is greatly appreciate.
