In today’s world, where companies use a variety of applications to conduct their day-to-day business, third-party patch management has become a central element of their cybersecurity strategy. These patches are security updates applied to third-party software, i.e. applications that are not integrated into the main operating system. For example, applications such as Adobe Reader, Zoom and Google Chrome are widely used, but often neglected when it comes to securing them.
So why has third-party patch management become essential for businesses? Let’s find out why.
Third-party patch management: what exactly are we talking about?
Third-party patch management is the process by which companies monitor, download and apply security patches for all software used within their systems, including those not directly integrated into the main OS (operating system). Unlike Windows security updates, for example, third-party software often requires separate management to keep it up-to-date and secure.
The aim is to plug potential vulnerabilities in each application. Without these patches, third-party software can become prime targets for cybercriminals, who often exploit vulnerabilities in unpatched applications to penetrate corporate networks.
Security risks associated with unupdated third-party applications
Unupdated third-party applications represent a major risk for businesses, as they open the door to cyber-attacks. Here are a few examples of risks associated with poor management of third-party patches:
- Unauthorized access to data: Hackers can use vulnerabilities in third-party applications to gain access to sensitive corporate information.
- Malware propagation: A vulnerable application can serve as an entry point for malware, which can then spread throughout the network.
- Data loss or corruption: Attacks linked to out-of-date applications can result in the loss of critical data, a particularly high risk in sectors such as finance or healthcare.
- Non-compliance with regulations: Many regulations (such as Law 25) require companies to keep their software up to date to protect personal data. Failure to do so exposes the company to sanctions.
Why do companies often neglect to install third-party patches?
Updates for operating systems like Windows are well integrated into corporate IT management practices, but patches for third-party applications are often ignored. Why? Here are some common reasons:
- Management complexity: Each application has its own update cycle, making manual management of all patches particularly difficult.
- Lack of visibility: Many companies don’t have an overview of all the software they use, especially in large organizations where each department uses different applications.
- Limited resources: IT teams, often already overloaded, lack the time to monitor and apply patches for each third-party software.
In reality, this negligence can be costly. Cybercriminals are well aware that third-party software is less protected, and target it specifically to bypass corporate defenses.
The benefits of proactive third-party patch management
Integrating rigorous third-party patch management into your security strategy offers many benefits:
- Reduced risk of cyber-attacks: By applying patches as soon as they become available, companies reduce their exposure to vulnerabilities.
- Improving system stability: Updates are not just about security; they are also about fixing bugs and improving application performance.
- Regulatory compliance: Regulators often impose strict security standards that include software updates to minimize the risk of data leakage.
- Productivity gains: By automating the patch management process, IT teams can concentrate on more strategic tasks.
How to set up effective third-party patch management
Implementing third-party patch management can be a challenge, but there are some key steps that can help you make the process smoother:
- Use a patch management tool: Many specialized tools, such as NinjaOne, automate the detection and application of third-party patches, greatly simplifying the process.
- Set priorities: Identify critical applications and prioritize their updates. Some applications, used more frequently or with access to sensitive data, require more rigorous monitoring.
- Follow security alerts: Subscribe to software vendor security alerts to be informed as soon as a new vulnerability is identified.
- Test patches before deployment: Some patches may cause incompatibilities. Always test updates on a small number of machines before applying them to the whole network.
Best practices for managing third-party patches
A few tips for successful third-party patch management :
- Automate as much as possible: Choose a tool that automatically downloads and installs updates to save you time.
- Document all updates: Keep a log of all updates applied and vulnerabilities patched for complete traceability.
- Talk to your MSP partner: Make sure he or she understands the importance of third-party patching and knows how to manage this process effectively.
Conclusion
In a world where IT security is a priority, third-party patch management cannot be neglected. Third-party applications are an important part of modern IT environments, and they can become security vulnerabilities if they are not regularly updated. By integrating a proactive patch management strategy, companies can not only strengthen their cybersecurity, but also improve the performance and stability of their systems. So, are you ready to take control of your third-party patches?
