What protocol, used by IPsec, manages connection settings and authenticates endpoints?

• A. Internet Key Exchange (IKE)
• B. Transport Layer Security (TLS)
• C. Simple Key Management for Internet Protocol (SKIP)
• D. Internet Security Association and Key Management Protocol (ISAKMP)

Answer: (A)

The Internet Key Exchange (IKE) protocol is integral to IPsec as it is specifically designed to negotiate, establish, and manage security associations (SAs) and to authenticate the endpoints in an IPsec connection. IKE automates the process of establishing a shared secret, which is crucial for the secure exchange of keys used for actual data encryption during the session. IKE operates in two phases: the first phase sets up a secure, authenticated communication channel and establishes a secure session key for further communications, while the second phase focuses on negotiating the IPsec SAs for the actual data transfer. This process ensures that the devices involved in the communication can trust each other and securely exchange keys, which is vital given the potential threats to data privacy and integrity in network communications. While other options might be related to security and key management, they do not have the same primary function as IKE in the context of IPsec. Transport Layer Security (TLS), for example, is used primarily for securing data in transit over different protocols but is not part of the IPsec framework. Similarly, Simple Key Management for Internet Protocol (SKIP) and Internet Security Association and Key Management Protocol (ISAKMP) pertain to key management and security associations, but it is I
