Release Notes:

Atomicorp Threat Intelligence System (BETA):

The Atomicorp Threat Intelligence (TI) engine is a real-time blacklist of shared intelligence sourced from the ASL community. Initially launched as a WAF module the TI engine can be enabled in ASL Web under Settings->ASL Configuration->Web Application Firewall->Atomicorp Threat Intelligence System.

As the TI continues to develop, we will be adding threat analysis tools to visualize the attack patterns of malicous activity, TI Lookups on IP addresses, and the ability to report additional analysis on attackers.

Firewall Changes:

IPSet support is now implemented in the ASL Firewall. IPSet features:

* Extremely large firewall policies, into the billions of entries

* Major reduction in memory usage

* Load times for huge rulesets are considerably faster (seconds vs minutes)

* Polices are swapped rather than reload, this eliminates any outage caused by clearing a list in pure iptables managed environments

The Ipset firewall implementation requires the ASL kernel, non-ASL environments will fall back on the slower legacy iptables firewall management. ASL kernel users using a locked module policy (ALLOW_kmod_loading=no) will require a reboot to activate the ipset system. Until the system has been rebooted the legacy iptables method will be used.

Viewing firewall policies will require the “ipset list” command to see the contents of each ipset used. The existing iptables method will show the reference to the ipset, but not its contents. Example:

-A ASL-GEO-BLACKLIST -m set --match-set ASL-GEO-BLACKLIST src -j ASL-GEO-BLACKLIST-LOG

to view an ipset:

ipset list <listname>

Firewall whitelists and ACL's are now loaded ahead of any blacklist, or active response policy.

Plesk Changes:

Plesk 12 instituted a new configuration layout in the psa-proftpd packages. This new layout moves proftpd configuration files under /etc/proftpd.d. This same method has been adopted by ASL for older versions of plesk, and retires the previous ASL configuration files and replaces them as follows:

/etc/proftp-tls.conf -> /etc/proftpd.d/50-plesk.conf

/etc/proftp-asl.conf -> /etc/proftpd.d/50-clamav.conf

Cpanel Changes:

Apache 2.4 on cpanel is now supported by ASL. However for performance reasons we do recommend cpanel users continue using Apache 2.2.

Updated Packages:

psa-proftpd 1.3.5-7
