What encryption method is commonly used for SSL VPN connections on Firebox?

The encryption method commonly used for SSL VPN connections on Firebox is Secure Sockets Layer (SSL) or Transport Layer Security (TLS). Both SSL and TLS are cryptographic protocols designed to provide secure communication over a computer network. When establishing an SSL VPN, these protocols ensure that the data transmitted between the client and the server is encrypted, protecting it from interception and eavesdropping. This is critical for maintaining the confidentiality and integrity of sensitive information being transferred, making SSL or TLS the standard choice for securing VPN connections.

In the context of VPNs, SSL and TLS work to authenticate the client and the server, negotiate encryption algorithms, and establish a secure channel for communication. This allows remote users to securely connect to a network, ensuring that their data remains protected while traversing potentially insecure networks, such as the internet.

While the other options relate to various aspects of networking and security, they do not directly represent the encryption method specifically used for establishing SSL VPN connections. For instance, Public Key Infrastructure (PKI) relates to the management of digital certificates that can be used to facilitate SSL/TLS communications, but it does not function as the encryption method itself. Similarly, Advanced Encryption Standard (AES) is indeed a commonly used encryption algorithm but is not
