TTCSIRT 428.16.04.24: Importance of Keeping Your VPN System Up to Date

Remote-access VPN systems allow off-site users to tunnel into protected networks, making these entry points vulnerable to exploitation by threat actors. From the Trinidad and Tobago perspective, the exploitation of outdated remote-access VPN systems is one of the most successful attack vectors executed against local organizations. This email serves as a critical reminder about the importance of keeping your VPN systems up to date.

Here’s why:

• Security Patches: Updates often address vulnerabilities discovered in the software. These vulnerabilities are frequently exploited by attackers to gain unauthorized access to your networks. By patching promptly, you significantly reduce the risk of a security breach.
• Improved Performance: Updates can also include bug fixes and performance enhancements. This ensures a smoother and more reliable VPN experience for everyone using it.
• Compatibility Updates: New updates may be necessary to maintain compatibility with other network devices and software. Outdated software can lead to connection issues and malfunctions.

To ensure our VPN remains secure and functional, I recommend the following:

• Schedule Regular Updates: Set a recurring schedule for checking for and installing updates for the VPN system. This could be weekly, monthly, or based on the vendor’s recommendations.
• Testing After Updates: After installing an update, it’s important to perform basic tests to ensure the VPN functionality remains unaffected.
• Stay Informed: Subscribe to notifications from your VPN system’s vendor to stay informed about critical updates and security alerts.

Thank you for your cooperation in securing Trinidad and Tobago!
