What Is Third-Party Patch Management? Benefits & Risks
Core Components of Third-Party Patch Management
Managing third-party patches effectively boils down to three essential components. These pillars address the challenges organizations face when juggling updates across various software platforms and ensure a structured approach to keeping systems secure.
Building a Complete Asset Inventory
The first step in successful patch management is knowing exactly what software is running across your organization. Without this knowledge, it’s impossible to manage updates effectively. A centralized system is key for achieving this visibility, as it helps create a clear picture of your IT environment’s landscape.
A thorough inventory should catalog all third-party applications, from popular tools like Adobe Reader and Java to niche software tailored to your industry. This inventory must include details such as software names, version numbers, installation locations, and how the tools are used across departments.
Organizations often discover hidden software – applications installed without approval or legacy systems that have been left unchecked. These “shadow IT” elements can introduce risks if they’re overlooked.
Importantly, this inventory shouldn’t be static. As new software gets installed or existing programs are updated, the database must be updated in real time. This continuous visibility becomes especially critical when vendors release emergency patches to address critical vulnerabilities.
Risk-Based Patch Prioritization
Given the sheer volume of vulnerabilities discovered monthly, patching everything immediately is unrealistic. As of spring 2024, the CVE (Common Vulnerabilities and Exposures) Program had documented over 230,000 security vulnerabilities, with new ones added daily by NIST. This overwhelming number makes prioritization essential.
A risk-based approach focuses on addressing vulnerabilities that pose the greatest threat. For example, vulnerabilities actively exploited by attackers should be at the top of the list. Tools like the CISA Known Exploited Vulnerabilities catalog can help identify these high-priority issues. Additionally, the potential business impact of a vulnerability should guide decisions. For instance, a flaw in a customer-facing application demands immediate attention, whereas a similar issue in a rarely used internal tool can be scheduled for a later update.
A real-world example highlights this approach: In June 2023, attackers exploited the Fortinet SSL-VPN Zero-Day vulnerability (CVE-2023-27997) to execute remote code without authentication, leading to several breaches. This incident underscores the importance of focusing on vulnerabilities that are actively being used in attacks.
By combining threat intelligence with an understanding of business impact, organizations can allocate resources where they’re needed most, ensuring critical vulnerabilities are addressed promptly.
Setting Up Testing and Validation Processes
Once patches are prioritized, the next step is testing them to ensure they don’t disrupt system operations. This step is vital but often challenging – around 50% of security teams report difficulties in this area. However, skipping testing can lead to unintended consequences that outweigh the benefits of the patch.
A proper testing environment should mirror the hardware and software configurations of production systems. This setup helps identify potential compatibility issues, performance problems, or functionality disruptions before patches are rolled out to critical systems.
Testing should follow a structured process that evaluates patches not only for their security fixes but also for any potential side effects. After initial testing, patches should be deployed in stages, starting with less critical systems. If no issues arise, the deployment can then proceed across the broader IT infrastructure. This phased approach minimizes risk and allows teams to catch problems that might not surface during initial tests.
Continuous monitoring after deployment is equally important. It ensures that patched systems are functioning as expected and helps identify any delayed issues that could emerge days or weeks after installation. This ongoing oversight balances the need for security with the goal of maintaining system reliability.
Steps to Implement Third-Party Patch Management
Strengthening your patch management program requires a systematic approach that focuses on visibility, prioritization, and validation. By breaking the process into three key phases, you can better defend your organization against vulnerabilities and improve overall security.
Discovery and Assessment
Start by gaining a complete understanding of your technology environment, going beyond basic inventories to uncover all third-party software in use – including any unauthorized installations. With organizations now using an average of 130 SaaS applications – a fivefold increase since 2021 – each application represents a potential risk, making thorough discovery a non-negotiable step.
Once you’ve identified the software, conduct a vulnerability assessment to determine where to focus your efforts. Modern vulnerability management tools can pinpoint critical flaws and offer actionable mitigation strategies. This is especially critical as the National Institute of Standards and Technology (NIST) adds over 2,000 new vulnerabilities to its National Vulnerability Database every month.
To allocate resources effectively, classify assets based on their risk level and importance to business operations. For instance, prioritize core business applications over less critical tools. This targeted approach ensures that your limited resources are used where they matter most. Additionally, security ratings can provide ongoing insights into vendor security practices, keeping you informed of emerging risks in real time.
Once the vulnerabilities are assessed, the next step is to acquire and implement the necessary patches safely.
Patch Acquisition and Deployment
After identifying and prioritizing vulnerabilities, the focus shifts to obtaining patches from vendors and deploying them across your systems. This phase requires careful coordination to maintain a balance between security and operational stability.
Establish direct communication with vendors to ensure timely patch acquisition. Subscribing to vendor notifications and security bulletins can help you stay ahead of critical updates. Many vendors also offer automated feeds that integrate with patch management tools, simplifying the process further.
Before deploying patches, test them in an environment that mirrors your production setup to catch any potential compatibility issues. For critical patches addressing active threats, you might need to bypass or compress the usual testing process. In such cases, having predefined escalation and rollback plans is essential.
"For example, an organisation may have a policy that says ‘any patch that is fixing a vulnerability that is known to be actively exploited should be patched as soon as possible and outside the normal patching cycle,’ but other organisations may have a policy that says ‘any patch that has a CVE rating of 9.0 or higher must be patched as soon as possible and outside the normal patching cycle.’" – Nathan Hunter, IT security & operations manager
Deploy patches in phases, starting with less critical systems to minimize disruptions. Automation can also play a key role here, handling tasks like patch discovery, vulnerability scanning, testing, and deployment with minimal manual intervention.
Monitoring and Reporting
The final phase ensures that your patch management efforts are effective and that your systems remain secure. This involves continuous monitoring and detailed reporting to track progress and refine the process over time.
Real-time tracking of patch deployment provides visibility into which systems have been updated, where patches failed to install, and where manual intervention is needed. Dashboards in modern patch management tools make it easy to spot bottlenecks and ensure nothing is overlooked.
To demonstrate the program’s effectiveness, track compliance metrics such as the time it takes to patch critical vulnerabilities, the percentage of systems with up-to-date patches, and the number of incidents related to unpatched software. A 30-day timeline is often recommended to keep systems current with security updates.
Post-deployment, monitor system performance to quickly identify and address any issues. Regular audits ensure that patches have been applied successfully and are functioning as intended. This should include a mix of automated checks and periodic manual reviews.
Finally, reporting is crucial for maintaining transparency and justifying investments in patch management. Reports should highlight successful deployments, recurring challenges, and progress toward security goals. This information is particularly valuable during audits or when presenting to leadership, as it underscores the importance of ongoing patch management efforts.
Tools and Automation for Third-Party Patch Management
Automation tools have revolutionized patch management, turning what used to be a painstaking, time-consuming process into a streamlined, efficient system. These tools not only help secure IT systems but also free up valuable resources. With IT teams dedicating an average of 240 hours per month to patch-related tasks and only 31% of application patches being distributed through automation, there’s clearly room for improvement.
Choosing the Right Patch Management Tools
Modern patch management tools go far beyond simply installing updates. When evaluating potential solutions, it’s essential to focus on features that align with your organization’s specific needs and security priorities.
- Agentless patch management: This simplifies deployment by removing the need for endpoint agents. It reduces overhead and ensures seamless updates without disrupting operations.
- Vulnerability assessment integration: The best tools can integrate with your existing security systems to assess vulnerabilities and prioritize patches based on actual risk levels. Many also use AI and machine learning to evaluate criticality and recommend strategies based on potential business impact and exploit likelihood.
- Support for diverse environments: In today’s IT landscape, tools must handle Windows, Linux, macOS, and third-party applications – all from a single platform.
- Advanced features: Look for sandbox testing, rollback options, and automated workflows that minimize disruptions to operations.
