IKE - Internet Key Exchange is often used in conjunction with what security standard?

SSL (Secure Sockets Layer), and its successor TLS, primarily secure application-layer traffic using certificates and separate key exchange mechanisms, not typically IKE.

OPSEC (Open Platform for Security) is a Check Point framework for integrating security solutions, not a security standard that IKE directly operates with.

IKE is specifically designed to create and manage Security Associations (SAs) for IPsec, defining the protocols and cryptographic keys used for secure communication within an IPsec VPN tunnel.

Kerberos is a network authentication protocol that provides strong authentication for client/server applications by using secret-key cryptography, operating independently of IKE for its key exchange.
