More than 60% of data breaches are the result of unpatched software. Not only can the system present security problems, but it may also be easily exploited by attackers who are using a legacy system. Patch management makes the most recent patches and fixes available to ensure software is up-to-date and secure.
However, what do you do to improve the patching process?
The Patch Management Process
Asset Discovery and Inventory
You can’t patch something that you don’t know exists. It begins with a detailed inventory of all the devices, operating systems, and applications that you have in your environment. Organizations can keep this inventory up and running without data silos and in real-time with AI-powered IT automation; there are several tools for them to do so.
Vulnerability Scanning & Assessment
If detected in the inventory, a list of known software vulnerabilities is scanned, and the detected version of the software is compared with versions of the software known from inventories like CVE. A severity score is given for each vulnerability, which determines the priority on which vulnerabilities are patched first. Vulnerability management and patching go hand-in-hand in terms of Cyber Security.
Patch Testing and Deployment
Any patch released for a live update needs to be tested in a staging area to ensure that it doesn’t cause any problems. In controlled deployments, patches get deployed like this: Automated patch management software programs schedule patches, distribute them to hundreds of endpoints, and ensure that they’re installed. This has a direct correlation to endpoint security management, and it should be possible to verify that all endpoints are patched and comply.
Why Patch Management Matters for Cybersecurity
Hackers continually look for older versions of software and for known vulnerabilities, which can be as quickly as a few hours after a disclosure. Managed Detection and Response (MDR) and patch management provide a multi-layered protection with real-time threat visibility and continuous patching. Timely security updates are also required by other compliance regulations, like HIPAA, SOC 2, and ISO 27001; otherwise, it can lead to serious penalties and audit failures.
The importance of a strong Patch Management Program
- Limits exposed areas and pinpoints any vulnerabilities and closing points for an attacker to penetrate.
- Resolves bugs and enhances the performance of the system.
- Meets regulatory needs as per the cybersecurity regulations.
- Avoids substantial security events and recovery costs, resulting in reduced IT costs.
- Aligns all devices and enhances the overall health of the endpoint.
Managed Cloud Operations extends patching to the cloud instances and containers to make sure that all infrastructure is protected.
Best Practices in Patch Management
The project’s schedule is at risk with work: The first critical zero-day on an internet-facing server, whether it is from now or from the past, is the first one. Rank all patch cycles based on CVSS score and the business context.
Automate where possible: Hand patching can be time-consuming and may be mistakes. With AI workflow automation, smart and adaptive patching workflows can be created that adapt according to risk signals and system availability.
Design and follow a patching pattern: Regular updates every month; critical patches as/when needed. When combined with Backup and Disaster Recovery services, a patch can be quickly restored without any loss of data in the event that the patch is problematic.
Common Patch Management Challenges
Legacy systems and older software may not be able to take advantage of the newest patches; this is another challenge, but network segmentation should be a part of other controls too. There is also patch fatigue, though; after hundreds of patches are sent out each week or month, an important one will likely be missed.
Cloud security audit services can be employed to identify some of the gaps in cloud security, which may not be possible for internal security teams to identify through patching.
Create a Patch Management Strategy That Scales
Ensure patching is included within your vulnerability management program, so that new vulnerabilities will be automatically placed on your priority list. Have all patch logs, test results, and deployment reports documented- compliance audits require these.
AI4IT’s managed IT services are patching on steroids, in your on-premises and cloud infrastructure, and delivering you a single view of compliance and security. Re-review strategy every 4 months – threat and environment will change.
