What is a patch management process? Patch management is the process of acquiring, testing, and installing many patches (code modifications) on current applications and software tools on a computer.
This allows systems to stay up to date on existing patches while also evaluating which patches are acceptable.
Managing patches becomes simple and straightforward as a result.
Patch management is mostly performed by software businesses as part of their internal efforts to resolve issues with various versions of software programs, as well as to assist in the analysis of existing software programs and the detection of any potential security flaws
Software patches assist in the resolution of issues that arise after the software's initial release.
Patches are generally concerned with security, although some are also concerned with specific program functionality.
Patches are generated for a variety of reasons, including resolving system faults or just increasing overall functionality and software performance.
The three most prevalent types of patches are:
1. Security patches: These patches are designed to fix newly discovered security vulnerabilities, which are often found after hackers have already exploited them.
2. Bug patches: These patches fix application errors as well as common and uncommon bugs that may arise during normal use of the systems.
3. Performance and feature patches: These patches may include general performance improvements, such as quicker computation speeds or lower resource requirements. They can add quality of life enhancements that make using the programs easier and faster.
The six steps in the patch management process are:
1. Create a baseline OT asset inventory: The first issue that many businesses confront is compiling a comprehensive asset inventory to determine what assets are connected, where they are situated, and what software is installed. Businesses should compile a reasonable asset list, either manually or through the use of existing corporate tools or agent-based solutions.
2. Compile a list of software patches and vulnerabilities: The second step is checking which patches are available and required. Operators must investigate patches to see what, if any, security issues are addressed.
3. Identify vulnerabilities and prioritize: Use the asset inventory to identify which assets should apply which updates. You’ll need to compile lists of prospective software patches and link them to assets to determine whether they are relevant.
4. Stress test samples in lab environment: Apply the patches to a representative sample of assets. To assure that the fixes will not cause problems in your production environment, stress test the machines.
5. Apply the patches: Consider applying the changes to batches of assets. To be sure there won't be any major complications, dip your toes in a few times before leaping in completely.
6. Track progress: To protect the new configuration and ensure compliance, any changes to the initial baseline must be logged and entered into corporate change management workflows so that the before and after are documented.
A patch management tool is a tool that automates the entire patch management process, from the identification of missing patches to the process of patch deployment to endpoints.
A centralized patch management server streamlines the entire procedure. You can use a patch management tool to deliver third-party software patches all from a single point of control.
Patch management tools aid in the reduction of system-related failures, allowing you to boost production while reducing the costs associated with poor patch management. Instead of manually maintaining patches and updates on your network's many devices, you can focus on key business tasks that enhance revenue.
