Much attention is placed on perimeter security and preventing attacks from outside the network. Much less attention is focused on attacks within the network, where an attack is more likely to occur. A solid security strategy employs many layers of coordinated security. Security Network Traffic with IPSec Security Network Traffic with IPSec The IP Security ( IPSec) suite of protocols was introduced to provide a series of cryptographic algorithms that can be used to provide security for all TCP/IP hosts at the Internet layer, regardless of the actual application that is sending or receiving data. With IPSec, a single security standard can be used across multiple heterogeneous networks, and individual applications need not be modified to use it. Security Network Traffic with IPSec Security Network Traffic with IPSec IPSec has two principle goals: To protect the contents of IP packets. To provide a defense against network attacks through packet filtering and the enforcement of trusted communication. Security Network Traffic with IPSec Security Network Traffic with IPSec IPSec has a number of features that can significantly reduce or prevent the following attacks: Packet sniffing. Data modification. Identity spoofing. Man-in-the-middle attacks. Denial of service attacks (DoS). IPSec IPSec IPSec is an architectural framework that provides cryptographic security services for IP packets. IPSec is an end-to-end security technology. Each computer handles security at its respective end with the assumption that the medium over which the communication takes place is not secure. IPSec IPSec IPSec has many security features designed to meet the goals of protection IP packets and defend against attacks through filtering and trusted communication....
