Using Yum Plugin Security to verify Red Hat updates (Free Guide)

Keep your WordPress blog secure and up to date with Yum Plugin Security! Yum Plugin Security is the leading WordPress security plugin, providing proactive security measures to protect your blog from cyber attacks, data breaches, and other security threats.

As the complexity of the global IT landscape continues to increase, companies are increasingly looking for innovative solutions to ensure their IT infrastructure is secure. One of the most important components of any IT solution is its patching and updating strategy.

With the latest security risks, companies must ensure their Red Hat updates are not only updated regularly but also verified for authenticity. One way companies can achieve this is through the use of a Yum Plugin security solution.

What is a Yum Plugin Security Solution?

A Yum Plugin security solution is a tool used to add additional security measures when updating applications from the Red Hat network. The solution verifies the authenticity of the update against the existing environment, guaranteeing any changes to system libraries and binaries are from trusted sources.

It also enforces a patch-level accuracy of any updated software, ensuring optimal system performance.

Red Hat Security Advisory (RHSA)

RHSAs contain one or more security fixes and might also contain bug or enhancements fixes. RHSAs are generally considered the most important type of errata for many organizations. RHSAs are ranked using a severity rating of Low, Moderate, Important, or Critical based on the severity of the vulnerability.

Red Hat Bug Advisory (RHBA)

RHBAs always contain one or more bug fixes and might contain enhancements, but do not contain security fixes. Because RHBAs are released for bug fixes, they are often considered more important than an RHEA in priority.

Red Hat Enhancement Advisory (RHEA)

RHEAs contain one or more enhancements or new features and do not contain bug fixes or security fixes. Essentially, a RHEA is released when new features are added and an updated package is shipped.

We can use the yum-plugin-security tool to verify Red Hat updates.

 This tool provides additional security checks for the packages that are installed on your Red Hat system. Here is a step-by-step guide to using yum-plugin-security:

Step 1. Install the yum-plugin-security package

yum install yum-plugin-security

Step 2. Update the package repository metadata:

yum updateinfo

Step 3. List available security updates:

sudo yum --security list updates

Step 4. Install security updates:

 sudo yum --security update

5. Retry failed updates

sudo yum --security update-minimal

If any security updates fail to install in the previous step, use this command to retry and install the updates with minimal dependencies.

Step 6. Verify installed packages

sudo yum --security check-update

This command will display packages that have available security updates, but are not currently installed on your system.

Step 7. Generate a security report:

sudo yum --security report

This command will generate a report of all available security updates for your system. By regularly using yum-plugin-security, you can ensure that your Red Hat system is up-to-date with the latest security patches.

Note: It’s important to keep in mind that this guide assumes you have properly set up and configured your Red Hat system, including its package repositories and yum configuration.

yum updateinfo list --sec-severity=Critical
yum updateinfo list --sec-severity=Moderate

How Does a Yum Plugin Security Solution Work?

The Yum Plugin security solution uses a combination of third-party software libraries and advanced authentication protocols to verify the Red Hat update. It checks the integrity of the file to be updated against the signature provided by the vendor, ensuring the files have not been tampered with. It also verifies the integrity of the system libraries and binaries, making sure they are up-to-date and from a trusted source. Finally, it uses patch-level accuracy to ensure the latest versions of any updated software are correctly installed and running.

What are the benefits of a Yum Plugin Security Solution?

A Yum Plugin security solution provides organizations with a reliable and secure method for updating their Red Hat environments. It helps to ensure the updates are genuine, preventing unauthorized third-party code from being introduced. It also provides an extra layer of security for system libraries and binaries, increasing their longevity. Additionally, by providing patch-level accuracy, it helps ensure optimal system performance and reliability.
