Introduction

The rules come in two forms:

1) Real Time Rules

2) Delayed/Unsupported Rules

Real Time/Supported Rules

Real Time Rules Download

Step 1) Download the file VERSION

https://www.atomicorp.com/channels/rules/subscription/VERSION

This file will contain the following fields:

ASL_VERSION=3.2.14-31
APPINV_VERSION=201305181247
CLAMAV_VERSION=201307181043
GEOMAP_VERSION=201307191033
GRSEC_VERSION=0
KERNEL_VERSION=3.2.48-54
MODSEC_VERSION=20130719110199
OSSEC_VERSION=201307171751
WAF_DELAYED_VERSION=201305151625
WAF_ENGINE_VERSION=2.7.4-15

Step 2) Download the latest rule file

Each rule file will contain the version of that rule file. For example, using the version information above the latest modsecurity rules version would be:

https://www.atomicorp.com/channels/rules/subscription/modsec-20130719110199.tar.gz

Note: This is not a valid version number. Please check the VERSION file for the current version of the real time rules.

We recommend you use a tool like wget or curl to download the rules.

Step 3) Optional: Confirm the rule file is valid

We sign each rule file with GNUPG. Each rule file includes a paired file with a .asc extension. This includes the digital signature for that rule file. For example, to download that file for the rule file above you would download this file:

https://www.atomicorp.com/channels/rules/subscription/modsec-201307191101.tar.gz.asc

You can use a tool like gpg or PGP to check the digital signature on this file. For example:

gpg modsec-201307191101.tar.gz.asc

If the file is valid, you will see a response similar to this:

gpg: Signature made Fri 19 Jul 2013 11:01:24 AM EDT using RSA key ID 4520AFA9 gpg: Good signature from "Atomicorp (Atomicorp Official Signing Key) <support@atomicorp.com>"

You can download our GPG key from this URL:

Step 4) Lint your rules

Our rules are built to support the latest stable version of modsecurity. modsecurity changes regularly, including new capabilities, the retiring of old capabilities and changes in the rule language. It is therefore critical that you always use the latest stable version of modsecurity supported by our rules. That version is kept up to date at the URL below:

https://www.atomicorp.com/wiki/index.php/Atomic_ModSecurity_Rules#Minimum_Version_of_Modsecurity_Required_to_use_the_rules

You will want to check to make sure the latest rules work with the version of modsecurity installed on your system. ASL does this automatically, if you are not using ASL you will need to make sure you have a method in place to do this for your DIY setup or a test environment.

Delayed/Unsupported/Free Rules

The Delayed/Unsupported/Free rules are available at the URL below. Keep in mind the Delayed feed is released at least 90 days after the realtime feed (that includes any fixes) and is unsupported.
