Using the security functionality of YUM

The yum package manager is the default package manager used to manage software within the Red Hat-based systems. This means that if we want to install, uninstall, or update any software, doing it with yum saves the day. A few of the examples can be as follows:

yum install httpdyum update httpdyum remove httpd

With this said, yum also includes security-specific features that allow system administrators to search, list, and install security-specific updates on the system. This feature also has the capability to only install security updates, leaving aside other updates.

To check security-specific updates, let's run the following command:

~]# yum check-update --securityLoaded plugins: fastestmirror* base: ...
