Advantage of using CA for VPN

[kjanakiraman]

Can some one let me know the advantage of using CA for Cisco VPN clients to connect to the corporate network. I am planning to implement microsoft CA with cisco pix firewall and make the clients connect through the CA.

Thanks in Advance

As I understand it, the primary advantage is that with CA you are no longer having to manually configure keys for authentication. Also it is much more difficult to compromise the CA than to compromise a manually configured key.

Benefits of Digital Certification

Because each VPN Client and each router has its own digital certificate and authentication is handled by the CA, a network is more scalable and provides a more secure authentication with digital certificates than with pre-shared keys or wildcard pre-shared keys. With digital certification, you can configure unlimited numbers of VPN Clients without having to change the gateway configuration.
