Cisco Systems VPN Client is a software application for connecting to virtual private networks based on Internet Key Exchange version 1. On July 29, 2011, Cisco announced the end of life of the product. No further product updates were released after July 30, 2012, and support ceased on July 29, 2014. [4]
Virtual private network (VPN) is a network architecture for virtually extending a private network (i.e. any computer network which is not the public Internet) across one or multiple other networks which are either untrusted (as they are not controlled by the entity aiming to implement the VPN) or need to be isolated (thus making the lower network invisible or not directly usable).
The OpenConnect project also offers an Cisco AnyConnect-compatible server, ocserv, [20] and thus offers a full client-server VPN solution. OpenConnect and ocserv now implement an extended version of the Cisco AnyConnect VPN protocol, which has been proposed as an Internet Standard . [ 21 ]
IKE uses X.509 certificates for authentication ‒ either pre-shared or distributed using DNS (preferably with DNSSEC) ‒ and a Diffie–Hellman key exchange to set up a shared session secret from which cryptographic keys are derived. [2] [3] In addition, a security policy for every peer which will connect must be manually maintained. [2]
Cisco AnyConnect VPN Client uses TLS and invented DTLS-based VPN. [34] OpenConnect is an open source AnyConnect-compatible client and ocserv server that supports (D)TLS. [35] Cisco InterCloud Fabric uses DTLS to form a tunnel between private and public/provider compute environments. [36]
The Simple Certificate Enrollment Protocol still is the most popular and widely available certificate enrollment protocol, being used by numerous manufacturers of network equipment and software who are developing simplified means of handling certificates for large-scale implementation to everyday users.
Transport Layer Security (TLS) is a cryptographic protocol designed to provide communications security over a computer network, such as the Internet.The protocol is widely used in applications such as email, instant messaging, and voice over IP, but its use in securing HTTPS remains the most publicly visible.
The OCSP responder uses the certificate serial number to look up the revocation status of Alice's certificate. The OCSP responder looks in a CA database that Carol maintains. In this scenario, Carol's CA database is the only trusted location where a compromise to Alice's certificate would be recorded.
