As your company has grown, so has the number of remote workers. The VPN began as a secure way to access company resources in the event that somebody could not come into the office to work; however, now a large number of the employees are dedicated remote workers, which means the attack surface area has expanded considerably. While some degree of risk must be accepted in operating any remote access technology, effective technical controls should be implemented to mitigate the impact of compromised sessions. You and your team of network security analysts are tasked with reviewing the current IPsec configuration and making considerations on alternative designs that may further secure remote access connections. You have decided the best approach is to set up a test VPN to prototype different configurations. Complete the following on the Workstation machine: Using the Add-VpnConnection PowerShell cmdlet, create a new split-tunnel, globally-accessible VPN connection. This VPN will connect to the test environment's VPN server at 202.20.1.2 through an IKEv2 tunnel, using EAP for authentication, and specify an encryption level of "Required." Name your new connection "yourname_/Psec2" where yourname refers to your own name.

Give two protocols within IPSec?

You have completed your construction of the IPsecVPN, allowing remote employees to securely connect to the corporate network. Employees have been able to successfully access company resources, and management is pleased now that they can filter traffic on remote company computers. However, some time has passed since the initial deployment, and a trend of complaints about dropped connections has emerged, causing prolonged reconnection periods and requiring some employees to manually reconnect. After speaking with remote employees to try identifying a pattern, you discover this is happening whenever the employee switches to a different network or network attachment point, such as from wired to wireless. Further investigation reveals that only employees without their VPN client credentials saved are being forced to manually reconnect. You suspect that their IP is changing when they switch connections, and that when it does, new Security Associations (SA) for the tunnel are created. This would explain why those with their credentials saved experience minimal impact, while those without their credentials saved are forced to authenticate again manually. Recalling that the Mobility and Multihoming protocol (MOBIKE) enables clients to continue using existing Security Associations across IP changes, you decide MOBIKE will solve the issue for the latter and reduce reconnection period for the former. Using the internet, research how to enable MOBIKE support for your IPsec tunnel in pfSense. Then, using the Workstation system, connect to the pfSense WebGUI and implement your changes.
