modseccfg 0.7.3.post2

Editor to tame mod_security rulesets

mod_security config GUI

• GUI to define SecRuleRemoveById settings on a vhost-basis
• Tries to suggest false positives from error and audit logs
• And configure mod_security and CoreRuleSet variables.
• Runs locally, via ssh -X forwarding, or per modseccfg ssh:/ remoting.

Installation

• You can install this package locally or on a server:

   pip3 install modseccfg
  

• And your distro must provide a full Python installaton and mod_security:

   sudo apt install python3-tk ttf-unifont libapache2-mod-security2
  

Start options

• To run the GUI locally / on test setups:

   modseccfg
  

• Or with sshfs remoting directly to the servers filesystem:

   modseccfg root@vps5:/
  

  A little slower on startup, but allows live log inspection. Requires preconfigured ssh hosts and automatic pubkey authorization. Be aware of the implicit ~/mnt/ point, if connecting as root.

Alternatively there's also slow X11 forwarding (ssh -X vps modseccfg) or xpra --start ssh:vps5 --start=modseccfg to run it on on the server.

Usage

You obviously should have Apache + mod_security + CRS set up and running already (in DetectionOnly mode initially), to allow for log inspection and adapting rules.

1. Start modseccfg (python3 -m modseccfg)
2. Select a configuration/vhost file to inspect + work on.
3. Pick the according error.log
4. Inspect the rules with a high error count (→[info] button to see docs).
5. [Disable] offending rules
   • Don't just go by the error count however!
   • Make sure you don't disable essential or heuristic rules.
   • Compare error with access log details.
   • Else craft an exception rule ([Modify] or →Recipes).
6. Thenceforth restart Apache (after testing changes: apache2ctl -t).

See also: usage remoting, or preconf/recipe setup, or the "FAQ".

Notes

• Preferrably do not edit default /etc/apache* files
• Work on separated /srv/web/conf.d/* configuration, if available
• And keep vhost settings in e.g. vhost.*.dir files, rather than multiple <VirtualHost> in one *.conf (else only the first section will be augmented).
• Requires some setup for the recipes (notably *.preconf includes for vhosts), but not for basic rule disabling/modifications.
• File→Install packages are Debian-only
• Reporting scripts also require Ruby
