SSL VPNs are remote access platforms that use TLS/SSL to provide authenticated users with secure connectivity to an internal network via a web portal or client.

Overview

SSL VPNs are remote access platforms that use TLS/SSL to provide authenticated users with secure connectivity to an internal network via a web portal or client. They are significant in cybersecurity because misconfigurations or vulnerabilities can expose internal resources to attackers, enabling unauthorized access, web shells, and persistence. The recent report on a flaw in ArrayOS AG VPN highlights the ongoing risk of SSL VPN vulnerabilities being weaponized and the need for prompt patching and monitoring.
