Frequently Asked Questions

ASL

aum is fully integrated into ASL and can be managed fully from the ASL web console. Please see the ASL_Configuration page for configuration options for ASL.

Rules only users

Does aum install more rules than asl-lite?

Yes, aum supports the full range of current rules available to rules only users. asl-lite did not.

Will aum keep mod_security up to date?

Yes. When an update is required by the rules, it will upgrade mod_security. When an update is not required by the rules, it will not upgrade mod_security.

Note: For rules only customers, you may see that ASL has a slightly older version of mod_security installed than with ASL. This is expected, as rules only systems do not have access to the full feature set in ASL, and occasionally we release updates to mod_security that not rule related but contains features ASL uses.

How can I enable/disable rules if I dont have ASL?

aum can disable rule classs, it can not disable/enable specific rules. You need ASL for that level of granularity.

How can I enable/disable rule classes if I dont have ASL?

Rule classes are enabled/disabled in the /etc/asl/config file. Setting a rule class to "yes" enables it, and "no" disables it.

Does aum use the /etc/asl/config file settings

Yes.

Do rule sets still need to be manually disabled?

No, check enable/disable the class in /etc/asl/config

Can I configure what aum updates?

Yes. The following options in /etc/asl/config are available for rules only aum users:

AUTOMATIC_UPDATES

Configures the update frequency for aum to download and install updates, such as new rules and signatures

NOTE: Updates can be run manually from the command line with aum -u.

If a software update is available you should follow your normal patch management procedure. We recommend that all users test upgrades on a test system before deploying to a production system. See "UPDATE_TYPE" below.

UPDATE_TYPE

Configures the behavior of the AUTOMATIC_UPDATE event. There are three options:

All: This will upgrade all compotents aum can update. Please see above for a list of components for ASL and rules only users.

Exclude-kernel: This will upgrade all ASL software, rule and signatures updates but not upgrade the kernel. (Note: This has no effect for rules only users of aum)

rules-only: This will exclude all software updates except for rules. Note: If a rule update requires an update to a component, for example modsecurity, the component will not be installed and that rule update will also not be installed.

Important Notice: Some rule and signature updates may not work without other compoents being updated, so if you set this to "rules only" be sure to regularly check your system for any software updates for ASL, or other components for rules only users (such as modsecurity) to be fully protected and to ensure compatibility.

How can I disable automatic updates?

Change this setting in /etc/asl/config

AUTOMATIC_UPDATES

to:

AUTOMATIC_UPDATES="none"

What is the /var/asl/data/templates directory for

Warning: modifications of these templates is not supported.

Templates in this directory are used to generate various configuration files aum needs.

How can I change the tortix_waf.conf file?

aum will manage this file from settings in /etc/asl/config. Editing this file directly is not supported.

What are the asl-php rpms for?

aum has its own, independent PHP engine that is only used by aum. aum does not use your operating systems PHP installation, and aums independent PHP engine is not used by your web server, web applications or Operating system. aum will not remove, replace, modify or upgrade or otherwise change your existing PHP installation. The asl-php RPMs are a completely separate independent isolated PHP engine that is not used by your operating system, or web server (apache, nginx, litespeed or any other web server), nor will they have any effect on any other application on your system, including any web or PHP applications.

These rpms will not and do not have any effect on your operating systems and are only installed in /var/asl and are only used by aum.

The asl-php rpm packages will always start with the name "asl", for example:

asl-php-cli-5.4.17-15.el6.art.x86_64
asl-php-5.4.17-15.el6.art.x86_64
asl-php-process-5.4.17-15.el6.art.x86_64
asl-php-gd-5.4.17-15.el6.art.x86_64
asl-php-pecl-apc-3.1.13-4.el6.art.x86_64
asl-php-common-5.4.17-15.el6.art.x86_64
asl-php-mysqlnd-5.4.17-15.el6.art.x86_64
asl-php-pdo-5.4.17-15.el6.art.x86_64

Do not change, remove, configure, block the installation or upgrade of, or otherwise modify the asl-php rpms or their configuration files, they are only used by ASL for its web console.

If you are having problems with your operating systems PHP, webservers PHP handler, webservers PHP applications or other PHP applications: aum did not install, upgrade, replace, configure or remove any part of your systems or web servers PHP installation. Contact your PHP vendor for assistance.
