Intel® Packet Protect User’s Guide

What is Intel
Packet Protect?
Packet Protect is designed to protect the confidentiality and authenticity of IP
traffic on your LAN.
Packet Protect can assist you in creating a departmental solution for your secu-
rity concerns.
Many data compromises are attempted from within a company firewall. Unless
you protect information as it travels on the network, it can be received by
unwanted users.
For example, employees retrieving confidential designs from a Research &
Development department server use Packet Protect to encrypt the information
while it travels on the LAN. Encryption protects the confidentiality of the infor-
mation. Each employee’s computer can also verify the integrity of the informa-
tion upon receipt.
Packet Protect Features
Packet Protect enables you to:
• Protect confidentiality and authenticity of IP traffic on your LAN using
Internet Protocol Security (IPSec), including Internet Key Exchange (IKE).
• Offload security tasks to an Intel PRO/100 S Management or Server
Adapter to optimize network performance.
Complete Your Security Solution
If you need to protect data stored on a computer, use operating system features
combined with Packet Protect. Packet Protect protects data traveling between
computers, not while it’s stored on a computer. You should use your operating
system features or network infrastructure element to provide access control to
certain areas of the computers on the network.
Hardware Acceleration
Implementing an IPSec solution can increase CPU utilization for computers that
use the IPSec software. This is common when implementing any IPSec solution
because of the intense computation required to encrypt, decrypt, and validate
packets. However, there is a way to offload security tasks from the CPU.
You can combine Packet Protect with the use of an Intel PRO/100 S Manage-
ment or Server Adapter to reduce CPU utilization. This frees CPU utilization for
other tasks, while reducing the impact to network performance.
Domestic and Export Versions
Packet Protect is available in both domestic and export versions. The export ver-
sion supports DES (56-bit) encryption only. The domestic version, available in
the United States and Canada, supports DES and 3DES (168-bit) encryption.
