Yum Command Check and Apply Only Security Updates

You can use the yum command to check and apply only security updates on a Red Hat or CentOS system. The yum-security plugin provides this functionality.

Here's how you can do it:

1. Install the yum-security plugin:

   sudo yum install yum-plugin-security

2. Check for available security updates:

   sudo yum update-minimal --security

3. Apply the available security updates:

   sudo yum update-minimal --security --sec-severity=Critical

rnExplanation:

• update-minimal is a yum-security command that only updates packages that have security updates available.
• --security option specifies that only security updates should be considered.
• --sec-severity=Critical option specifies that only critical security updates should be installed.

rnNote: The yum-security plugin is available in Red Hat Enterprise Linux and CentOS, but not in Fedora. If you're using Fedora, you'll need to use a different method to manage security updates.
