Key Points: Server Patching Explained

  • What is server patching: It is the process of applying patches to update or fix server software.
  • Why is server patch management important: Patching a server system ensures it successfully stores, sends, and receives data over the network and into your connected endpoints.
  • What are the risks in leaving servers unpatched: Unpatched servers leave the network open to security vulnerabilities, productivity loss, and risk of non-compliance.
  • How can patch management be automated: IT teams often use patch management tools or RMM platforms (e.g., NinjaOne) to autonomously detect, test, and deploy updates across all endpoints.

Patch management is a critical process in IT-powered environments. Server patching, in particular, is crucial to keeping these endpoints at a performance level and secure. Follow along this guide to learn how server patch management works and how to best execute it at scale within regulatory compliance.

What is server patching?

Server patching is the process of applying patches to update or fix your server software. Patching is needed to support the successful operation of your servers and verify that they’ll be able to perform their specific functions.

It’s an iterative process that’s often completed upon availability, though it may also be delayed or ignored with varying risks and consequences.

Why is server patch management important?

Patching a server system ensures it successfully stores, sends, and receives data over the network and into your connected endpoints. A server with poor health and tuning will be unable to provide its designated services or functions.

Security protection

Attackers are known to exploit vulnerable servers and other endpoints. Regular patching closes these gaps that could otherwise be an entry point for malware, ransomware, or rogue users.

System stability

Patches don’t just address security gaps; they also fix bugs and defects that can cause crashes, performance degradation, or downtime. As far as servers go, high availability is a must for business continuity and compliance.

Regulatory compliance

Many industries (e.g., finance, healthcare, government) need up-to-date patching as a key component of data protection and security frameworks. Failure to meet IT compliance can lead to hefty fines and reputational damage.

Operational continuity

Automated patching mitigates the risk of outages caused by known software issues, ensuring servers run smoothly with minimal disruption.

At scale, this is typically achieved with enterprise IT management tools or an RMM with autonomous patch management capabilities like NinjaOne.

Apart from operational integrity and compliance, patches enhance efficiency, optimize processes, or improve software compatibility among various systems. Regular patch management also significantly minimizes the number of entry points that threat actors can exploit across servers.

Common risks brought by unpatched systems

Risks that are associated with an unpatched server are the same risks that other types of unpatched software face, starting from:

  • Loss of data
  • Lost productivity
  • Security vulnerabilities
  • Suboptimal network conditions
  • Weakened cybersecurity
  • Non-compliance with regulatory and industry standards

When the server is unpatched, it is less resistant to cyber threats. Unpatched software can also have a noticeable impact on productivity, especially in industries or environments that have fully integrated IT workflows.

3 keys to a successful server patching process

Servers are more heavily configured and more sensitive, which means that the impact of them going down is much worse. If a patch breaks a user’s machine, the user might lose a day of work, but it’s not the end of the world. If you break a server with a patch, all members of your organization might be unable to work for an entire day. The effects are much larger, so server patching has much higher stakes.

1. Combine automatic and manual processes

Patch management needs modern solutions, though not all the way.

Automation can be used for tasks such as tracking available patches and scanning them, but manual testing and implementation remain key to ensuring that patches are positively affecting server performance.

2. Use a sandbox to test server patches

Before you deploy a patch to your server, you want to make sure it actually improves the system rather than breaking it. Sandbox testing allows you to evaluate any available patches without disrupting the live environment.

A sandbox is a non-production environment that allows you to safely test potential patches before they’re applied to production, which in this case is a server.

3. Implement server failovers

As a general rule of thumb, you should have backups in your IT environment wherever possible. The backup for a server is a server failover.

The server failover or failover cluster is programmed to automatically take control and replace the original server if it goes down, is offline, or another disaster breaks the system.

The general approach to server patching is very different from the approach to patching end-user devices. With end-user devices, the goal is to get them protected as quickly and efficiently as possible.

Server patching, in comparison, thrives in a more conservative approach. Likewise, it’s typically more difficult and time-consuming. Autonomous and manual processes are also both required to deliver consistent and stable outcomes.

FAQs

Critical security patches should be applied as soon as they are released. Many organizations follow a monthly patch cycle for routine updates, with emergency updates installed immediately when needed.

IT teams often use patch management tools or RMM platforms (e.g., NinjaOne Autonomous Patch Management®) to automatically detect, test, and deploy updates across all endpoints.

Some patches may require a server restart, which can cause brief downtime. However, planned patching schedules and staggered rollouts help minimize business disruption.

Patches and updates are essentially the same and are used interchangeably. Both deliver software updates that address weaknesses or vulnerabilities in the software system.

 

The key difference is that software patches are small updates released by software developers to fix specific issues or vulnerabilities in a program, while software updates are broader, with releases often coming in periodically to improve the overall functionality of the software.
