In today's digitized business landscape, the management and maintenance of software applications are pivotal for smooth operations. Software, in its intricate construct, is a perpetual work in progress and therefore, needs consistent updates or patches to address bugs, vulnerabilities, and feature upgrades.
With an average enterprise relying on an array of applications, servers, and end-point devices for day-to-day operations, a robust patch management platform is non-negotiable. This platform plays a crucial role in identifying, testing, deploying, installing, and documenting all relevant patches to keep the systems secure and stable.
However, as with all things tech, not all patch management solutions are designed equally, and what may be considered efficient by one organization might be insufficient for another. Therefore, an evaluation focusing on certain key criteria can assist IT teams in zeroing in on the most suitable solution for their organization's patch management needs. Let's delve into these criteria in detail.
Inventory Management A proficient patch management tool should be capable of maintaining a comprehensive inventory of all systems that can be patched. Critical data to be tracked includes the operating system, applications, current and past versions, patch groups, and patch dependencies. The location of this inventory, whether part of the patch system or in an existing configuration system, is a crucial consideration.
Patch Life Cycle Management In the realm of DevOps, with continuous integration/continuous delivery (CI/CD) processes, the patch lifecycle is integrated with software development for in-house applications. However, one must consider that patch lifecycles can demonstrate complex dependencies. Therefore, the platform must ascertain the feasibility of applying a patch and if an existing patch must be removed before the application of a new one.
Patch Testing and Deployment The ability of a patch management tool to test patches in a controlled environment is critical. A comprehensive testing environment should include the ability to enable debug-level logging on patch installations to ensure no errors were overlooked or to discern what triggered a failure.
Moreover, a patch management solution should be able to deploy patches to all intended systems, including establishing deployment policies, groups, and methods apt for the item to be patched.
Trusted Sources and Patch Prioritization A reliable patch management tool should be knowledgeable about trusted uploaders and publishers and should be able to validate the patch. Additionally, the tool must have the capability to either automatically or manually prioritize patches for deployment.
Patching Architecture and Third-Party Support The most effective patching solutions employ both an agent and agentless method of scanning, providing the most flexibility. Additionally, an ideal patch management solution should be able to patch third-party applications.
In conclusion, navigating the increasingly intricate landscape of ransomware and other cyber threats requires an effective patch management solution. Even though finding the perfect fit might be challenging due to the myriad of vendors, having an emphasis on key criteria will place decision-makers in a better position to narrow down their choices.
Key Terms:
Patch Management: The process of managing a network of computers by regularly deploying all missing patches to keep computers up to date.
Inventory Management: The supervision of non-capitalized assets, inventory, and stock items - in this context, the details of systems that can be patched.
Patch Life Cycle Management: The process of managing the life stages that a patch goes through from introduction to removal from service or disposal.
CI/CD: Continuous Integration/Continuous Delivery, a method to frequently deliver apps to customers by introducing automation into the stages of app development.
Debug-level logging: A detailed logging practice that records information about a program's execution for debugging purposes.
Agent and Agentless Scanning: The two methods used in patch management where one involves an agent software on each client machine (agent-based), and the other uses
