What is the difference between SSL VPN and IPSec VPN?

The main difference between SSL VPN (Secure Sockets Layer Virtual Private Network) and IPSec VPN (Internet Protocol Security Virtual Private Network) is in the way they operate:

SSL VPN typically does not require the installation of a resident VPN client. It often relies on a web browser to establish the VPN connection, making it more convenient for remote users who may not want to install dedicated VPN software.

IPSec VPN, on the other hand, often requires the installation of a resident VPN client on the user's device to establish the VPN connection. This client software is necessary for configuring and managing the VPN connection.

Option C, stating that SSL VPN and IPSec VPN are the same, is incorrect because they have distinct characteristics as described above.

Option A is incorrect because it inaccurately suggests that IPSec VPN does not require a resident VPN client, which is not true in most cases.

Option B is incorrect because it wrongly claims that SSL VPN requires the installation of a resident VPN client.
