Intel(R) Packet Protect Software Supplemental Information Version 3.0 for Windows* 98 and Windows Me* ========================================================= NOTE: If you are using Windows NT*, open the readme.txt in the \PktPt\NT4 directory. Additional information is in the Intel Packet Protect User's Guide in the \Info\Protect directory on the product CD-ROM. Contents ======== - Overview - System Requirements - Installation - Certificate Installation Issues - Configuration - Compatibility - Security Exceptions for Communication - Communicating with Windows 2000 - Other Known Issues Overview ======== Intel Packet Protect is a departmental solution that helps protect Internet Protocol (IP) traffic as it travels between computers on your local area network (LAN). It protects data confidentiality and authenticity, and helps prevent data from being retrieved by intruders or hackers. Because many of the total data compromises are attempted from within a company firewall, it is important to protect sensitive data while it travels on your company's LAN. Though Intel Packet Protect securely transmits traffic on the network, it does not protect the data while it is stored on a computer. Use your operating system features to provide access control to sensitive areas of your network. Intel Packet Protect uses Internet Key Exchange (IKE) and Internet Protocol Security (IPSec) to protect communications on your LAN. Both IKE and IPSec are protocol specifications being developed by the Internet Engineering Task Force (IETF). Intel Packet Protect uses pre-shared keys or certificates for IKE credential verification. Intel Packet Protect supports only Entrust certificates. Intel Packet Protect does not compress packets before they are sent using IPSec. System Requirements =================== - Microsoft Windows* 98 or Windows Me* - DCOM98, v1.3 or later. This can be downloaded at: http://www.microsoft.com/com/dcom/dcom98/download.asp. - KMPAPI32.DLL (only if certificate support is required). This file comes from the Entrust* Engelligence* installation (see below). - 40 MB minimum available hard disk space. - 32 MB RAM minimum, 64 MB RAM recommended. - 233 MHz Pentium(R) processor (performance level or better). - Intel PRO/100 family of network adapters. Installation ============ NOTE: If you are upgrading from a prior version of Intel Packet Protect, there are several steps which you must follow in order to successfully upgrade. See "Installing Packet Protect" in the user guide for complete information. Configure PROSet II to enable IPSec: ----------------------------------- 1. Open PROSet II. 2. In the left pane, select Network Components. 3. Right-click on the name of the adapter you want to use. 4. Select Enable IPSec in the pop-up window. 5. Click OK. At this time the bindings are formed for IP Security. 6. Type in your IP configuration information. 7. Re-start the system in order for the IPSec bindings to take effect. To install Intel Packet Protect: ------------------------------- 1. With the product CD inserted, browse to the CD-ROM using Windows Explorer. 2. Double-click \PktPt\Win98\setup.exe. 3. Follow the prompts on the screen. 4. Re-start Windows when prompted. Certificate Installation Issues =============================== If you get a "Missing KMPAPI32.DLL" error message during Intel Packet Protect certificate support installation, you will need to download and install the Entrust* EntrustIPSec* Negotiator* Toolkit: 1. Using your Internet web browser, go to http://www.entrust.com/ developer/ipsec/ 2. Select "Download". 3. Enter your member ID and PIN if necessary. 4. Select a download location on your hard drive. 5. Using the Windows Explorer, find and run the EntrustIPSec installer program. 6. After installation, go to the installation directory (default is C:\Program Files\Entrust Toolkit\IPSec\Lib\) and move "KMPAPI32.DLL" to the Windows system directory (the default is C:\Windows\System\). 7. Re-start the Intel Packet Protect certificate support installation. Problems during Certificate Installation process: ------------------------------------------------ If you have problems logging in to Entrust/Entelligence, it may be due to an improper setting in the Entrust .INI file: 1. Using a text editor, open /Winnt/entrust.ini 2. Locate the tag "FipsMode". 3. Set the value to "0" (zero). 4. Save and close the file. If you get an error message, "Intel Packet Protect Credential Store (CS) component problem: failed to get the subject name in the certificate", it could be due to a duplicate conflicting profile name. To resolve this, log out of Entrust/Entelligence, then start up the Certificate Installer again. Configuration ============= When you install Intel Packet Protect on a computer, you set up basic security settings the computer will apply to communication attempts. Optionally, you may set up security policies to apply different security settings to specific types of communication attempts. Refer to the Intel Packet Protect User's Guide in the \Info\Protect folder on the product CD-ROM for configuration details and deployment examples. Compatibility ============= Intel Packet Protect is designed to offload encryption and authentication tasks to Intel adapters that have an integrated encryption co-processor, such as the PRO/100 S family of adapters. LAN adapters that do not support offloading will still work but system and network performance will not be optimal. Intel Packet Protect is not supported on Intel PRO/1000 gigabit adapters. Intel Packet Protect does not support dial-up adapters. Intel Packet Protect does not support IPSec tunnel mode. Each computer that will communicate in a protected way using Intel Packet Protect must use a pre-shared key or by using an Entrust certificate. Intel Packet Protect does not support the Kerberos authentication method. Intel Packet Protect computers can communicate with Windows 2000 IPSec computers by setting up each computer's policy to use the same settings. You cannot use Intel Packet Protect to manage security policies for Windows 2000 IPSec computers, or vice versa. Compatibility with Mixed Versions of Intel Packet Protect --------------------------------------------------------- Ideally, all computers should be running on the latest version of Intel Packet Protect. See "Installing Packet Protect" in the user guide for complete information. If you continue using a previous versions of Intel Packet Protect on one or more systems, note the following: - You may experience performance problems. - If you are using Entrust certificates for authentication, machines running Intel Packet Protect version 2.x will not be able to connect with the other machines. There is a patch available for systems running Microsoft Windows NT. Download it from http://support.intel.com, under "Downloads and Software". Security Exceptions for Communication ===================================== In order for a client machine running Intel Packet Protect to communicate with a Domain Name Server (DNS) or a Windows Internet Naming Service (WINS) server, you must employ one or more security exceptions to allow communication. These and other security exceptions are discussed in the Intel Packet Protect User Guide, under the topic "Common Security Exceptions". Communicating with Windows 2000 =============================== Intel Packet Protect 3.0 can communicate with the IPSec implementation in Windows 2000, but there are two restrictions: * Use the "All IP Traffic" protocol filter * Use a matching preshared key Use the "All IP Traffic" Protocol Filter ---------------------------------------- On Windows 2000, the rule used to communicate with Intel Packet Protect clients must be set to "All IP Traffic" protocol filter, even if you are only interested in specific protocols (e.g. TCP, UDP, etc) on top of IP. For example, if you are only interested in TCP communications between Windows 2000 and Intel Packet Protect, you must create a new rule in Windows 2000, which can communicate with the active rule or default behavior on Intel Packet Protect. If you select TCP as the protocol filter in the Windows 2000 rule, the communication may fail. You MUST select "All IP Traffic" filter instead. Use a Matching Pre-Shared Key ----------------------------- Since all default rules in Windows 2000 use Kerberos for authentication (not supported in Intel Packet Protect version 3.0), you must either add a pre-shared key to the authentication methods in the "All IP Traffic" default rule, or you must create a new rule with "All IP Traffic" protocol filter AND a matching pre-shared key as one of its authentication methods. This pre-shared key must match what is in use with Intel Packet Protect. Other Known Issues ================== - During client startup, the client may communicate "in the clear" for a few seconds, even though it may require protection. This is because the computer is initiating itself on the network. During this time period, the IP stack is open to IP-based network intrusions. - The Default Rule conflicts with Secure Responder behavior. Secure Responders should initiate communication without security. However, the Default Rule, if present, takes precedence over the Secure Responder behavior and always initiates communication with security. In this case, Secure Responders act like Secure Initiators when the Default Rule is present. You can delete the Default Rule. If you do, then Secure Responders will initiate communications without security, or "in the clear." - When you install certificate support on a computer, Intel Packet Protect assumes that certificate software has already been installed on that computer. The certificate installation will fail unless the certificate software has been previously installed. - When using the Default Rule, computers that operate as Secure Responders will initiate communication with security and not in the clear. - Multicast traffic (defined as having an IP address between 224.0.0.0 and 239.255.255.255) and broadcast traffic will always be transmitted in the clear and leave the system open to attacks from intruders. The IPSec specification does not cover multicast and broadcast packets, therefore these packets will neither be secured nor filtered. The side effect is that the machine will still accept packets from unauthenticated users. This may lead to a possible misuse. - Security exceptions and ports that are kept open allow traffic to pass with no security. This leaves the system open to intruders. - If you are installing on a non-English operating system which uses a double-byte character set (e.g., Kanji), the directory path to the executable files must be specified in ANSI text (e.g., English). If there are any double-byte characters in the path, Intel Packet Protect will not install properly. - Some Windows 2000 versions are using DES policies instead of 3DES. If the server has Intel Packet Protect installed, and the rule used involve only 3DES (in various combinations) there will be no communication between Windows 2000 clients and the Intel Packet Protect server. To enable the use of 3DES you have to install the Windows 2000 High Encryption Pack.
