Linux patch management is the process of managing patches for applications running on Linux computers. Managing patches in Linux involves scanning your Linux endpoints to detect missing patches, downloading patches from vendors' sites, and deploying them to the respective client machines.
Enhancing your overall system performance, Linux patch management helps you maintain a secure and productive environment. ManageEngine's all-around patching solution, Patch Manager Plus, helps resolve compatibility issues and provides hardware support for all Linux users.
Patch Manager Plus' Linux patch management features help you:
Be sure to keep your Linux servers and all the machines in your Linux environment up to date, so you don't miss out on any of the new features provided by the manufacturer.
Patch Manager Plus supports Linux security patches and non-security updates (only for Red Hat, CentOS and Ubuntu machines) with bulletin IDs for computers running the following versions of Linux:
Linux versions Redhat 8 and CentOS 8 are now supported on Patch Manager Plus and Desktop Central
While Linux being open-source has its advantages, it can be quite complex to devise a proper Linux patching strategy for that very same reason. Owing to the abundance of Linux distros, it is almost impossible to create a unified patch management strategy for all of them and generally requires more knowledge, unlike Windows.
Let's take a look at the list of Linux patch management strategies that you can implement using Patch Manager Plus to ensure patch compliance in your network.
Manually checking for updates regularly, testing them, and installing them on your endpoints is undoubtedly a rigorous task. The easiest workaround? Automating the entire patching process in your environment.
With automated patch management software, you can ensure regular patching across your endpoints, thereby keeping vulnerabilities and exploits at bay.
In the event of a patch causing operational or functionality issues in the production endpoints, rolling it back can be a serious headache for admins. Moreover, such events can cause system downtime as well as a drop in productivity.
As a result, always test your patches in a pilot group of endpoints (also known as a test group). Once approved, these patches can be deployed in phases to the production network.
Vulnerabilities marked as critical should be patched as soon as possible since these are more likely to be exploited by threat actors and cyberattackers. This is why it's important to always prioritize deploying critical or important patches first. Less severe patches, optional updates, etc. can then be deployed based on regular deployment schedules.
Generating detailed reports is crucial for security auditing purposes and tracking network-wide patch compliance. Regularly generate reports that specify patching dates, version info, deployment results, and other details.
As a thumb rule, always look for a Linux patch management tool with a central dashboard that features reports on:
You can deploy your patches in your Linux machines manually by following the steps below.
sudo apt-get update # Fetches the list of available updates
sudo apt-get upgrade # Strictly upgrades the current packages
sudo apt-get dist-upgrade # Installs updates (new ones)
yum check-update # To check for the list of available updates
yum update # Installs updates for all the packages
zypper check-update # To check for the list of available updates
zypper update # Installs updates for all the packages
However, manual deployment often results in errors. There are many steps involved, and it can be difficult to identify where a mistake was made. Due to the complexities involved, patch management is often rather time-consuming for users. Thankfully, Patch Manager Plus has come up with a solution for all these complications—complete automation using the Automate Patch Deployment (APD) feature.
After automation is applied, the entire patch management process becomes more efficient. This Linux patch management software automates the entire process. It scans for missing patches, downloads them, and tests them in a non-production environment; if the patches don't cause any issues, Patch Manager Plus approves them to be rolled out in the production environment and schedules reports.
To automate the patch management process, simply follow the steps below.

In the world of Linux, patches are more than just something you might apply to the source code of a kernel. With the right Linux patch management software in hand, you can deploy Linux security patches and non-security updates (only for Red Hat, CentOS and Ubuntu machines) that help keep your Linux endpoints secure, error-free, and updated with the latest features.
Patch Manager Plus provides a module for Linux patch management that helps admins ensure that all the Linux machines on the network are up to date with critical Linux security patches and non-security updates (only for Red Hat, CentOS and Ubuntu machines), ensuring there are no security vulnerabilities in the network. With the help of this tool, you can patch your Linux endpoints and third-party updates for Linux. You can also choose to install patches based on severity. With Patch Manager Plus, patch management for Linux computers is no longer a challenging task.
Note: For patching Red Hat and SUSE, it is recommended that all the managed endpoints have valid system licenses.

Linux patching is the process of applying patches (or software codes) to fix vulnerabilities or to add new features to the Linux endpoints across your network.
Patching your Linux systems is crucial to prevent threat actors from exploiting vulnerabilities in them. It strengthens data security and fends off recurring attacks. Some patches also add new features and functions to the applications.
ManageEngine Patch Manager Plus supports patching for over 850 third-party applications across Windows, Mac, and Linux endpoints, offering all-around protection. With detailed, customizable reports, admins can get comprehensive visibility of the patch compliance in their network. Explore the features of Patch Manager Plus from here.
