VPNs are essentially network devices and subject to many of the same security issues you would find in a router or a switch. If you are running a software VPN, then your VPN can have many of the issues you find on your network’s servers.

A hardware VPN solution can suffer from a number of security vulnerabilities, including:

• Weak default password
• Insecure default configuration or misconfiguration by the installer

Based on your text discuss the following potential weaknesses of VPN implementations.
