Answer / rahul gupta
Internet Protocol security (IPSec) is a framework of open standards for helping to ensure private, secure communications over Internet Protocol (IP) networks through the use of cryptographic security services. IPSec supports network-level data integrity, data confidentiality, data origin authentication, and replay protection.
IPSec helps provide defense-in-depth against:
1.Network-based attacks from untrusted computers, attacks that can result in the denial-of-service of applications, services, or the network.
2.Data corruption
3.Data theft
4.User-credential theft
5.Administrative control of servers, other computers, and the network.
