ASL is always kept up to date through its built in update management system. Unlike other security solutions, ASL works by combining security at all layers, from the Kernel all the way up to the application layer to provide the most complete protection available for Linux servers.

 

ASL helps to ensure that your system is compliant with commercial and government security standards. ASL includes the most secure kernel on the market, automated system lockdown and hardening engine, userspace and host Intrusion Prevention Systems (IPS), malware/rootkit detection and elimination, blacklisting technologies, firewall and web application firewalling to protect multiuser and web application hosting environments like no other solution. ASL is uniquely effective at addressing emerging threats posed by vulnerabilities in todays complex systems and applications, such as web hosting environments, multiuser systems, CRM's, ERPs, forums, shopping carts, Content Management systems and custom applications.

ASL

New Features in 3.0:

 

New ASL Dashboard consolidates Attack & Event summary, Module Status, Load monitor and RSS feed.

 

New operating systems supported:

 

  • Cloudlinux 5

  • Scientific Linux 5 & 6

  • CentOS 6

  • Red Hat Enterprise Linux 6

  • Xen virtualization (as a guest OS)

 

New control panels supported:

 

  • CPanel

  • Directadmin

  • Interworx

 

New online documentation system:

 

  • All ASL Web, rule ID's are now linked to their documentation page.

  • This will allow you to click on the event ID to find out more about what this event is, what causes this event to occur, and what actions, if any, you may need to take. For example, if the Web Application Firewall event 340162 is triggered, you can click on “340162” in the GUI and you will be able to read more about that type of attack, how to tune your system if its a false positive and so much more!

 

Firewall Rule Management System:

 

  • An advanced rule management system that will import your existing rules into a powerful web based interface

  • Use with, or without third party firewalls. All your firewalling needs can now be addressed from ASL.

HIDS (Host Based Intrusion Detection) Rule Manager:

 

  • Modify the Active Response policy globally or per rule

  • Change Severity Level per rule

  • Rules can be enabled/disabled globally or by virtual domain.

  • Rules can be set to different severity levels,

  • Rules can have their base response policy elements modified to include shunning, email alerts, and logging.

 

Intelligent Repeat Offender blocking:

    ASL will intelligently modify block times based on the recurrence of attacks from a particular source. This will allow your system to treat “one time” offenders differently from repeat attackers, properly blocking real malicious users from launches new attacks.

 

New File Integrity management system:

 

  • Web based GUI Interface that allows for list or tree view sorting.

  • "Notify" lists, this allows notifications to be sent to different email addresses for change alerts to different files.

  • "Watch" configuration, allows for the definition of what files or directories the system will monitor for changes. Configuration options allow for real-time monitoring, user/group ownership changes, permissions, checksum, and diff reporting. Diff reporting will include the changes made to the file in the body of the alert message for ascii files.

  • "Ignore" lists, allows for files or directories to be explicitly ignored from monitoring.

 

Event Manager enhancements:

  • Allows for searching for any string in the data field
