This is a fairly basic "just the security updates, please!" guide for CentOS 6+.
This assumes you're root or have used sudo su.
First, you may need to ensure you have the yum security plugin:
rpm -qa | grep -i yum-plugin-security
If you don't, you can update it with the following.
yum install yum-plugin-security
Now let's check if there are updates:
yum --security check-update
If there are available updates, there will be results after this command.
To update, run the updater with the option --security to specify security updates only.
yum update --security
That's it!
Is something badly out of date? Did this work for you? Please post a comment to help others who might use this for guidance. I originally wrote these instructions around 2013.

Unfortunately, default CentOS repositories do not provide information about security patches, this article works only for EPEL repo.
