9 Best Free and Open Source Patch Management Software

Most of you must have heard the story of David and Goliath-the 9 feet tall giant Philistine warrior –‘Goliath’ who was killed by a young Israelite shepherd boy –‘David’ in combat. David had only a slingshot as a weapon but was able to defeat Goliath because he stroked at the right place-Goliath’s forehead, his most vulnerable part.

Same is true with the bugs and cyber threats. The irony is that I am referring to the 'bugs' as David and the whole IT system of an organization as 'Goliath.' A small malware or a loophole in the system can crash the entire system if the malware hits the right spot of vulnerability in the system. To safeguard our IT systems against this, we require an effective patch management system.

What is Patch Management?

The extreme threat of hacking activities and malicious cyber attacks necessitates companies to deploy patches frequently. Network security requires consistent efforts, so vendors regularly release various types of patches like hotfixes, roll-ups, service packs to keep the system updated. IT administrators install these patches to stay abreast with the latest security requirements. This is called as Patch Management. Patch Management is a complex process of installing software patches for addressing security concerns and vulnerable spots in the software system.  

Why is Patch Management critical?

Companies can lose a lot of money due to incessant cyber-attacks and malicious software bugs. The slowdown of servers hampers productivity, and any loss of data can be costly for your business. Therefore, it is essential to find the patches and fix them on time for ensuring the safety of the IT system which makes Patch management an integral part of the IT maintenance system.

Effective Patch management handling is very significant to maintain the stability of IT infrastructure. Even Microsoft corporation releases Windows updates on every second Tuesday of the month which is now called as the Patch Tuesday. Patch management is a continuous process which requires a regular application. This complex process necessitates the IT managers to use patch management software that can automatically fix patches and install updated codes for them.

What is Patch Management Software?

The Patch management software installs patches for addressing security concerns, cyber threats, and vulnerable spots in the software system. It manages scanning, validating, deploying, and reporting of the patch codes.  

Recent research testifies that even large companies have unprotected data and poor patch management practices, making them vulnerable to data loss. CISCO mentions in a report that 31% of organizations experienced cyber attacks on their systems. McAfee’s Economic Impact of Cyber Crime report mentions that around 7800 thousand records were lost in the year 2017 due to data breaches. Research suggests that most businesses take up to 150 days to notice data breach without proper IT security system or patch manager.

With the knowledge of the patch management process and the help of best software tools, IT professionals can provide a vulnerability free system to their organizations.

Evolution of Patch Management Software:

Patch Management has evolved significantly with time. Patch management was never required the way it is today. Earlier, for Windows-based systems, Windows Server Update Services (WSUS) was the endpoint for all patch related solutions. Many IT managers still argue that there is no need for patch management software as WSUS API environment is sufficient and safe for patch fixation. Their argument depicts patch management software as a redundant product. This is not true in the present context.

Organizations are not the same today as they used to be in the past. The complexities with which the present organizations work, makes WSUS a way too simplistic tool to handle the complex functionalities of IT systems. The cloud-based environments of today’s companies need customized patching solutions. They cannot rely solely on WSUS. Thus, the Patch management software came into existence to address these concerns.

Patch management software solved the issues that Windows WSUS failed to address or had limited capability of managing, such as failed windows updates, patches in the mixed OS environment, the limited ability of WSUS to patch third-party applications and the lack of reporting.

Features of Patch Management Software

features of patch management software

1.   Ability to scrutinize the System

The ability to scrutinize the whole system for threats and vulnerabilities is the first feature that one should look before finalizing the right patch management software for one’s purpose.

2.   Diagnostic capabilities:

Lab tests are used to identify the specific disease, and based on that only, final treatment can be prescribed. The patch management software should be able to diagnose the security glitch in the software correctly so that the glitch can be eliminated with a proper response. The patch management software should have a bird's eye view to identify the software flaws and should not miss anything. It should possess exhaustive search capabilities for seeking out the vulnerabilities.

3.    Reporting

It should also have the capacity to generate an accurate and high-quality report on all security parameters and patching requirements.

4.    Automated code installing:

 It should install the patches automatically without the need for manual set up. 

5.     Prioritizing updates:

 As soon as any communiqué regarding a potential threat is received by IT professionals, they start the assessment regarding the nature of the patch required. Categorizing patches according to the level of threat and urgency of fixation is critical for sound patch management. Some updates need immediate attention, and some can wait for sometime before getting patched. The patch management software should be able to figure out the difference between the two, and based on it should sequence the updates.

6.     Remote monitoring and patch fixation

Fixing patches on client computers individually is an arduous and inefficient process. Remote monitoring is a more scalable and optimal idea when it comes to patch fixation.

7.     Testing and validating

If not handled efficiently patch fixation may create other software related issues. Testing the patch on a small segment of software before applying to all systems is necessary. After installing the patch, it would be prudent to check all other system applications for their proper functionality. One should get ensured that the patch has not caused any other software paralysis.

The ever-increasing rate of cybercrimes, data theft, ransomware, malware, and phishing is the compelling factor that IT managers have to go the extra mile to ensure the safety of their IT infrastructure.  With cyber-criminals finding new ways to exploit vulnerabilities in the IT system, IT managers have to be extra vigilant and proactive to corner these cyber threats. One cannot wait for the ‘zero-day' attack to happen for initiating action.  

A preventive measure is required to deal with cyber-security concerns. There is a need for the system administrators to monitor, control, and manage the patch systematically and methodically.  A time-bound and responsive patch management system can safeguard the businesses against time, cost, and data losses.

Though the vendors provide patch services and updates but still third party patch management software is the need of the hour to create a full-proof cyber security system.

The vendors have their own limitations in realizing updates, patch codes, and security reports, which makes third-party patch management software indispensable for the IT system administrator. With the advent of technologies like virtual patching, IT managers have gained more control over their patch management system. A virtual patch prevents any malicious software to enter the system by monitoring the system traffic. It acts as a firewall until IT managers test, install, and validate the new patch codes. The future of patch management lies in the hands of the proactive companies that will invest in technological upgrades and consistently monitor their IT infrastructure for any perceived threats. Forecasting the vulnerabilities and acting swiftly for redressals with the patch management tool in their hands, will keep companies guarded from malicious cyber attacks.

The free and open source patch management software discussed in the article are significant addition to your WSUS or SCCM. Using efficient patch management software is the right approach to address the IT security concerns. One should deploy patch management software according to the need of his or her organization. You can choose from the software discussed in the article for your patch management needs.
