Issue Tracking moved to GitHub

The WAF-FLE Issue tracking moved to GitHub to make more clear the relation between an issue and the code that fix it.

WAF-FLE Issue Tracking moved to GitHubThe development code of WAF-FLE was on GitHub for many months, and many users have opened new issues there, while the “official” still the Google Code. To make things easier to all, I think that is better to concentrate this job in only one place, github.

I expect to solve all issues still on Google Code, if possible. While the issue tracking on Google Code is not closed (yet), I don’t expect new issues there.

Support WAF-FLE, Make a Donation

Support WAF-FLE, “Make a Donation” is a campaign asking you to engage with project.

WAF-FLE is a project conducted in spare time, with my personal effort, that offer to you a product useful to manage and improve the web application security of your company/organization. You can support this effort, and as some people had asked me how to donate to the project, I have created a PayPal donation button (on right sidebar) to allow those that want to support financially the project can do this in a simple way.

Any contribution is welcome. If the WAF-FLE is useful to your organization, consider make a donation, this will reduce my costs (with time, hosting, etc.), and will make things go faster in development.

Best regards,


Site became multi-language, added Brazilian Portuguese

Language Selection

The WAF-FLE website became multi-language, with addition of Brazilian Portuguese, to better address the Brazilian users community. All site was translated, even old posts (but something may have been overlooked). Try the languages available in right sidebar.

While WAF-FLE itself is available only in english, an effort was made to bring the Deployment Guide to Portuguese as well the website now.

This addition was possible by using a new theme and plugin, that simplify the translation process (while make a double work in site maintenance).

For while, just one mailing-list, so still writing in english there.


WAF-FLE 0.6.0 final(ly)

Dear WAF-FLE users,

after a long time working in many things no waf-fle related (time still short), and with the help of many valuable users, I’m releasing the version 0.6.0 (final) of WAF-FLE (download: waf-fle_0.6.0.tar.gz)

This version keeps all features and improvements from of 0.6.0-rc, and making room for new features in next version. I’d like to say a thank you to all users that had submitted bug reports and helped to improve this version.

All users should considering upgrade to this version once it corrected many bugs (from version 0.5.x and 0.6.0-rcX).

The most important change was a better parsing of logs.

Read the ChangeLog file a complete list of bug fixed.

Good WAF-FLing,

WAF-FLE: Deployment Guide, now available

Deployment Guide

I just publish the “WAF-FLE: Deployment Guide” (on the Documentation page). Is an extensive and step-by-step guide (but I know, is incomplete, at least in this first release). Is the first of an endless writing and editing.

It is directed to both new and current WAF-FLE users.

The topics covered range from Deployment scenarios, WAF-FLE installation and upgrade, Sensor Setup and Definition, using Event Feeder Configuration to help sensor side configuration (mlog2waffle and mlogc), and has Quick How-To for CentOS/RedHat, Debian/Ubuntu and FreeBSD . Finishing with some tips for Sizing and MySQL Tunning.

Comments, corrections and additions are very welcome and can be sent as a new issue ticket.

Version 0.6.0-rc1 available

Today the WAF-FLE Project is proud to release a new version of WAF-FLE: 0.6.0-RC1 (Release Candidate 1). This is a major release, with many new features, improvements and bug fixes (see ChangeLog for a complete list of changes).

The more relevant features in this version are:

  • Filter enabled Dashboard: Now you can use the filter in dashboard, all charts and tables are clickable, enabling the drill-down data on dashboard, updating the charts and tables to reflect the filter.
  • Delete events by filter: now you can use the filter to delete events at once, turning much more easier, for example exclude false positive events.
  • Compression of full events: You can choice if you want to compress full events (used to download raw events), make a huge difference in disk space used by database (saving around 60% of space).
  • You can define if WAF-FLE should use a header like X-Forwarded-For or X-Real-IP like source of source address in events. Very useful when you have a reverse proxy in front of ModSecurity. You can customize wich header should be used.
  • Support to ModSecurity 2.7 Engine-Mode variable, to let you know if an event has allowed (but logged) or if the sensor are in detection-only mode.
  • GeoIP support in dashboard, event and filter.
  • Setup script: to help in dependencies check, database creation/migration, making much more quick a setup in platforms where installation dependencies are not easily known.
  • mlog2waffle: a daemon to work as a replacement to mlogc. It is written in perl, and can work as service feeding events to WAF-FLE in real-time or scheduled in crontab. It must to be considered in beta stage, but seen to be reliable and fast.
  • Sensors and users management interface much improved, with more information and options.
  • Improved ModSecurity events parsing, supporting some new fields like stopwatch2.
