How does IPsec provide secure networking for applications within an organization?
IPsec (Internet Protocol Security) ensures secure networking by creating security associations (SAs) between peers. These associations define the necessary security parameters such as encryption and authentication algorithms, and keys to protect data. By establishing these security associations, IPsec ensures that the data transmitted between network nodes is confidential, integral, and authentic.
C. It enables sets of security associations between peers. IPsec (Internet Protocol Security) is a protocol suite that provides secure communication over Internet Protocol (IP) networks. It achieves this by authenticating and encrypting each IP packet within a communication session. One of the key concepts in IPsec is the establishment of security associations (SAs) between peers. Security associations are the combination of algorithms and keys used to secure communication between two devices. They define the security parameters for the communication, including the encryption algorithm, integrity algorithm, and keying information. By establishing these security associations, IPsec ensures confidentiality, integrity, and authenticity of the data being transmitted between network nodes. Therefore, option C accurately describes how IPsec provides secure networking for applications within an organization.
C. It enables sets of security associations between peers.
