Does Redhat classify their patches and what is their release schedule?

I'm putting together a paper on the different patch processes for various operating systems.

I need to get two questions answered.

1. How does RedHat classify their patches?
2. What is the patch release schedule for RedHat?

For Microsoft it's easy, Microsoft releases their patches on the 2nd Tuesday of each month and rates their patches as:

- Critical
- Important
- Moderate
- Low

Does Redhat employ a similar rating? How often does Redhat release updated patches?

Thanks for the help

Do a up2date
or yum if you are using fedora

it will list the patch you need to be upgrade. (and the type)
unlike microsoft, the Linux patch upgrade is go by the type.

The problem though is that I don't have a live machine. I want to know their general practices and not their specific patches for a machine.

Redhat have two classes of patches:

1.  Security
2.  Bug fixes/enhancements.

Patches are released as needed, particularly with security patches.

  The patches in RedHat call "Errata". As Tintin said, only 2 classes: Security (RHSA) and Bugfix (RHBA).
If you have RHN account, you will see "lock" icon for RHSA and "bug" icon for RHBA in Errata  page.

I would like to add to the above comments...

1. Red Hat (Enterprise Linux) has 3 levels, security/bug fix/enhancement
2. released as they occur

Red Hat also classifies each security patch with different levels;
low / modereate / important / critical

They also let you read the explaination to what the problem is and in some cases refer to an external site for more information.

You also have options on how you should update your clients, you can update all patches automatically if you like... (not that I would recommend it, getting to know your environment is always better...)
