provides a robust framework for securing data transmitted over IP networks. IPSec operates at the network layer and can be implemented through two main protocols: and (ESP). AH provides data integrity and authentication, while ESP offers confidentiality and can also provide authentication if needed.
(KMP) is essential for establishing secure communication channels and managing encryption keys securely. When implementing IPSec, organizations can choose between two modes: and . Transport Mode encrypts only the data payload, while Tunnel Mode encrypts the entire IP packet.
is a fundamental concept in IPSec, representing the negotiated security parameters between two entities. SAs are managed through the Key Management Protocol and dictate how data will be secured during communication.
and (ACLs) can be used in conjunction with IPSec to enhance network security. IDS monitors network traffic for suspicious activity, while ACLs control which packets are allowed or denied based on predefined rules. By combining these tools with IPSec, organizations can create a robust security architecture to protect their data and networks.
