Release Notes: This release includes the latest iteration of the Tortix Web Application Firewall (or T-WAF for short). The T-WAF is the next generation of the initial external WAF piloted with the plesk WAF module. It allows for dynamically redirecting local HTTP/HTTPS based traffic directly through the T-WAF module using firewall redirect rules. This is titled as a "local redirect", additionally the T-WAF supports "plesk" mode which replaces the original plesk-waf-setup application. Lastly, the T-WAF supports "remote" which allows the ASL server to act as a reverse proxy for downstream web servers.
As of this release the T-WAF module is considered a beta project and is not enabled by default. Users interested in beta-testing the T-WAF can activate it with: yum install asl-waf-module
The T-WAF will be licensed separately in a future release.
The 3.0.23 update also includes a beta feature allowing management of the default WAF response policy. Previously web attacks were handled as block inline, this update allows for the "redirect" response to a user defined URL. This URL can be used to pass information on the nature of the blocked attack including rule id, src ip, and internal event id.
Changelog:
- Add Tortix WAF (T-WAF)
- Retire plesk-waf-setup (replaced by T-WAF)
- Update, Add UNSUPPORTED to version info when distribution cannot be identified

Release notes: The ASL clock module may not report the correct time due to the timezone not being specified in the php.ini. That is something we're working on automating in a future release. Also a frequently requested "warnings only" modifier has been added to asl from the command line. This is useful if you were looking to use it for a daily email report.
The internal update subsystem has been expanded to handle more internal component updates to include the ASL kernel, and waf module provided the UPDATE_TYPE setting is set to allow those updates.
Changelog:
- Add clock to ASL Web
- Add new update display fields to WAF updates, Rootkit Protection, and Shell protection
- Add in the -warn flag to only show warnings / failures in scan and/or fix mode
- Update to configuration verification engine, FIXED is only reported if a setting is the secure state. Otherwise the true vulnerablity level is displayed.
- Update to integrity checks, /etc/webmin is now ignored by default
- Feature Request #XXX, hids_check will now maintain the localtime file in chroot in accordance with /etc/localtime

- Bugfix #XXX, update to asl_db_rotate to handle rotating larger database sizes (1+ million rows)
- Bugfix #XXX, tortixd rule reloading is moved out from the ASL Web interface, and into a queue system. This prevents the thread from dying in an interactive session.
- Bugfix #289, correct SMTP_AUTH plesk password checks to map to valid mailboxes. Correct output of plesk FTP check to show pass word column in order
- Bugfix #496, detect /var/log/snort/alert

This update brings a new capability to ASL which we are initially piloting for Plesk environments. It is a separate independent Web Application Firewall(WAF) for other web based services. In the context of plesk this both blocks attacks against the Plesk control panel, and adds in upload scanning to the Plesk file manager. The functionality of this module can be used on any web service, from control panel software like Plesk, Cpanel, Interworx, to web front ends on applications like Vmware and Oracle , or alternate web servers like Nginx, and litespeed. We will continue to expand this functionality on other control panels over the next few releases, and we encourage everyone to let us know via support, or in the forums about other web environments that you are interested in supporting.
