This plugin does not work on CentOS, at least not yet, there were previous
discussions. e.g.
http://centos-devel.1051824.n5.nabble.com/CentOS-devel-yum-plugin-security-and-shellshock-td5710031.html

I read this thread and also another, which is refered to therein:

To tell the truth, as a person who is not familiar with the
internal structures and procedures of tree building and
maintenance of the repositories, I don't really understand
why it should be so difficult to handle a "security-update" flag
for the update packages, but I have to believe the experts,
who make statements on this topic.

Here is what I picked up when reading the thread from devel list:

1. For a valid approach data for all packages over
the complete history of the major version is needed.

2. At the time the data is only sent to the announce mailing list
and it will need a big effort with also manual work to
collect all the data back from there.

3. "it would add significantly to the size required to
mirror CentOS and require a redesign of how we do trees completely (we
currently only push the latest tree for each live major version)." (Johnny
Hughes)

4. The developers fear that the yum-plugin-security functions
may seduce people to only install the security relevant packages,
which can cause problems.

5. The tools used by scientific linux repo maintainers,
who support a security classification,
are availabe under free software license.

My personal view is represented by the mails of Kevin Stange in this thread.
And I still hope that the issue will be solved by
integrating the "security update" flag into the
CentOS repositories in the future.

so far and thanks for your replies to all contributors in this thread,
