Linux Patch Management Software Effective Defense Option For Linux Systems

Why Patch Management Software for Linux?

All operating systems (OS) — whether it is Windows, Linux, Mac or any other OS — requires a patch management system to check for hotfixes, bug-fixes and other software patches issued by the vendor. Most patch management systems in the market focus on the Windows OS. The reason could be the volume of users, and the number of third-party applications built to run on the Windows OS.

In the same way, as bugs and vulnerabilities are found in the Windows OS (or any other operating system), they are also found in the Linux OS. Linux vendors release hotfixes and patches to address these problems. Earlier, cyber criminals did not focus their attacks so much on the Linux OS as on the Windows OS. Hence, reports of zero-day exploits and malware attacks were not frequently reported. However, as cyber criminals became more skilled they found that hacking into enterprises running businesses on Linux OS was more profitable.

Protecting the Linux OS has hence become essential and patch management is necessary to secure the OS and the enterprise data within.

20 Most Critical Vulnerabilities

Software vulnerabilities for the UNIX and Linux systems are some of the current programs listed as part of the top 20 most critical vulnerabilities by the US FBI and the SANS Institute. They can include:

  • Remote Procedure Calls (RPC)
  • Secure Shell (SSH)
  • Apache Web Server
  • File Transfer Protocol (FTP)
  • Line Printer Daemon (LPD)
  • BIND/DNS
  • Many More

As you can see, it is necessary to reduce the vulnerability of your system. While you still need a firewall and anti-virus software, Linux patch management is another option to ensure safety within your systems.

How to Automate Linux Patch Management

Manually checking for updates released by the Linux OS vendor regularly is not an impossible task, but it can be cumbersome. And if numerous endpoint systems connected to the enterprise network are running on Linux OS then it would not be possible to ensure proper execution of this task. The Comodo Patch Management module is a versatile software that automates much of the process. The software can scan the systems and find out the patches that are available.

The Comodo Patch Management module displays this information in an easy-to-read format that allows the administrator to quickly view the available patches on the patch management system dashboard in their order of severity, and apply hotfixes immediately based on their criticality (critical, optional, etc..,). Administrators can create policies to automatically apply patches to endpoints according to a specific schedule. These policies will keep selected endpoints up-to-date without the necessity of administrator intervention. Policies are built based on the type of patch (operating system or third-party), the schedule for the operation, the target endpoints, patch severity and other criteria.

The Comodo Patch Manager must be installed on the server, and an agent must be installed on the endpoints that need to be enrolled for the automated patch management. Once enrolled, the job is done. The Patch Manager dashboard enables easy viewing and management of agents and endpoints, and management of OS updates, patches, and applications.

The Patch Management Architecture for Linux is the same as that for the Windows OS and Mac OS.
