What is the purpose of IPSec policy?

The purpose of IPSec policy is to define the rules and parameters for securing internet Protocol (IP) communications by authenticating and encrypting each IP packet in a communication session. It establishes protocols for data integrity, confidentiality, and authentication, ensuring that only authorized users can access the network. By implementing IPSec policies, organizations can create secure virtual private networks (VPNs) and protect sensitive data transmitted over untrusted networks. Overall, it enhances the security of data transmission across potentially insecure environments.
