Reworked November 24, 2020 – Now Is the Time to Replace VPN With Zero Trust
What Is Wrong With VPN?
The perimeter methodology that VPN relies on makes it particularly vulnerable to attackers, said Steve Tcherchian, chief information security officer at XYPRO, a cybersecurity analytics company, by giving users and devices unfettered access to the network once they have been identified and authenticated at the perimeter. “Attackers love this,” he said. “Once they’re in, they can spend as much time as they need to move around from device to device. In some cases, once authenticated to the VPN, this could mean access to thousands of devices.”
Tcherchian said several recent data breaches can be attributed to this methodology of trust, and it enabled attackers to gain access to everything the vendor or contractor had done in the past. “This is no longer a sustainable security strategy,” he said. “Moving to a Zero Trust model removes that layer of perimeter security. Every user and device, whether outside the VPN or inside no longer has access to devices. Even if they’re inside the VPN, there is no access unless explicitly granted on an as-needed basis.”
