−
The application inventory module is designed to identify applications installed on the system by analysing it's source code. It can be a very CPU intense operation and is configured by default to run once per day. ASL supports configuring the Application Inventory to run either Daily, Weekly, or with the following setting in /etc/asl/config
 
−
 
−
APPINV_CRON="daily"
 
−
 
−
Valid settings for this field are:
 
−
 
−
"daily"
 
−
 
−
"weekly"
 
−
 
−
"off"
 
−
 
−
Changing this setting in /etc/asl/config does *NOT* require a policy update with "asl -s -f".

== ASL inside a VPS ==
+
−
 
+
−
All of the features of ASL work inside a VPS.  VPS technologies, such as Virtuzzo or OpenVZ abstract a single kernel running on the host system and share it with all the VPS'.  Therefore, a VPS does not have a kernel of its own, it uses the host systems kernel.  If you are using a VPS on a server that is not running ASL you will see several important kernel vulnerabilities reported in your system.  These vulnerabilities are real, and they can not be fixed from inside a VPS.
+
−
 
+
−
The ASL kernel, when used with VPS technologies, can only be installed on the host machine, this is because the VPS' themselves do not have their own kernel.  This is not to be confused with Virtual Machine technologies such as VMWare, KVM, Xen and others.  Those virtual machines do have their own kernel, and therefore the ASL kernel can be installed inside those virtual machines.  '''VPS', however, do not have their own kernel, they share the single host machines kernel.'''  To eliminate these vulnerabilities in a VPS the host server must be running ASL as well.
+
−
 
+
−
VPS's will also see "hidden processes" reported by ASL.  This is also expected as the rootkit detection capabilities of ASL are seeing hidden processes from other VPS' running on the system.  Therefore VPS customers that do not wish to get these alerts will need to turn off rootkit checks inside their VPS's.  To do this modify this file:
+
−
 
+
−
just modify this file:
+
−
 
+
−
/var/ossec/etc/ossec.conf
+
−
 
+
−
Search for this:
+
−
 
+
−
  <rootcheck>
+
−
 
+
−
you should see something like this:
+
−
 
+
−
  <rootcheck>
+
−
  <rootkit_files>/var/ossec/etc/shared/rootkit_files.txt</rootkit_files>
+
−
  <rootkit_trojans>/var/ossec/etc/shared/rootkit_trojans.txt</rootkit_trojans>
+
−
  </rootcheck>
+
−
 
+
−
Check that to this:
+
−
 
+
−
  <rootcheck>
+
−
  <disabled>yes</disabled>
+
−
  </rootcheck>
+
−
 
+
−
You will also want to disable the hidden process checks in the VPS that are performed by rkhunter:
+
−
 
+
−
You want to edit this file:
+
−
 
+
−
/etc/rkhunter.conf
+
−
 
+
−
Look for this line:
+
−
 
+
−
  ENABLE_TESTS="all"
+
−
 
+
−
Change it to:
+
−
 
+
−
  #ENABLE_TESTS="all"
+
−
 
+
−
Then look for this line:
+
−
 
+
−
  #DISABLE_TESTS="suspscan hidden_procs deleted_files packet_cap_apps"
+
  
−
And change it to:
+
Note: This utility is only valid post-installation.
  
−
  DISABLE_TESTS="hidden_procs os_specific"
+
== Release Notes ==
  
−
'''Do not disable these checks on the host server.'''
+
The latest ASL release notes are available in the [https://www.atomicorp.com/wiki/index.php/Atomic_Secured_Linux#ASL_3.2_Release_Notes ASL 3.2 Release Notes article].
  
−
If you are not on a VPS, then reports of hidden process means you do in fact have hidden processes. That means you are running some root level process that is hiding a process, or your system was compromised at some point in the past, and ASL has detected that a rootkit is installed.
+
You should also check to make sure your system meets the ASL requirements, which are documented on the [[ASL prerequisites]] page.

Introduction

Atomic Secured Linux(tm), or "ASL" for short, is a Unified Security Suite addon for Linux(tm) systems designed to protect servers against zero day threats. Unlike other expensive security "solutions" that pretend to achieve security through signature-based detection, known-vulnerability patching and other reactive methods, Atomic Secured Linux(tm) provides real proactive security. The only solution that protects both your applications and operating system, Atomic Secured Linux is essential for public-facing servers and shared-hosting environments.

And Atomic Secured Linux (ASL) is uniquely designed for beginners and experts alike. You just install ASL onto your existing system and it does the work for you, plus you can try it for free!

ASL works by proactively immunizing the system against whole classes of vulnerabilities, and combines security at all layers, from the firewall, to your applications and services, and all the way down to the kernel to provide the most complete multi-spectrum protection solution available for Linux servers today. It helps to ensure that your system is secure and also compliant with commercial and government security standards. ASL is uniquely effective at addressing emerging threats posed by vulnerabilities in todays complex systems and applications, such as cloud and web hosting environments, multiuser systems, CRM's, ERPs, forums, shopping carts, Content Management systems, custom applications and more.
