TIP: The tunnel setting is used by all packets selected using the address filters for the rule. Do not include any filters for host-to-host (non-tunneled) packets in the filter list for a rule with a tunnel.

1.Start the IP Security Policies snap-in if necessary.

2.Create an IP Security policy or modify an existing policy. To modify an existing policy, select the policy in the right navigation pane and right click the policy. Select Properties.

3.The IP Security configuration utility opens the Policy Properties dialog box. Select the Rules tab. Click Add to create a new rule or select a rule you want to modify and click Edit.

4.Configure a new rule or modify an existing rule with the appropriate address filter for the outbound tunnel rule or inbound tunnel rule, as described in “Outbound Rule” (page 34) or “Inbound Rule” (page 35). See “Step 4: Creating the IP Filter List and Filters for the Rule” (page 18) if you need additional information about configuring address filters.

Record the destination address; you will need it to configure the tunnel endpoint.

5.Return to the Rule Properties dialog box. Select the Tunnel Setting tab.

6.The IP Security configuration utility opens the Tunnel Setting dialog box. Select The tunnel endpoint is specified by this IP address.

Enter the IP address of the tunnel endpoint closest to the destination. Since this is an end-to-end tunnel, it is the same as the destination address in the address filter.

7.Click Close to close the Tunnel Setting dialog box.

8.If this is a new rule, complete the configuration by configuring the appropriate filter action, authentication methods, and connection type.

Click Close to close the Rule Properties dialog box.

Example

In this example, IPsec secures all packets between the Windows system and the HP-UX system using authenticated ESP.

The Windows system's address is 10.1.1.1

The HP-UX system's address is 10.2.2.2.

Windows Configuration

On the Windows system, you configure one rule for outbound packets and one for inbound packets.

Outbound Rule

The outbound rule is for packets from the Windows system (source address 10.1.1.1) to the HP-UX system (destination address 10.2.2.2). Figure 18 shows the address filter for this rule, and Figure 19 shows the corresponding tunnel settings:

UX IPSec Software specifications

HP-UX IPSec Software is an integral component of the HP-UX operating system, providing robust and secure communication capabilities for enterprise environments. As organizations increasingly rely on secure networking solutions, HP-UX IPSec stands out with its comprehensive set of features and technologies designed to safeguard sensitive data.

One of the core characteristics of HP-UX IPSec Software is its implementation of the Internet Protocol Security (IPSec) framework. This technology secures Internet Protocol (IP) communications through authentication and encryption, ensuring the integrity and confidentiality of data transmissions. By leveraging IPSec, HP-UX provides a secure method for connecting remote users and secure sites over untrusted networks, such as the internet.

A notable feature of the HP-UX IPSec Software is its support for both transport and tunnel modes. The transport mode encrypts only the payload of the IP packet, whereas the tunnel mode encapsulates the entire IP packet within a new packet, allowing for secure communications between entire networks. This flexibility enables organizations to tailor their security strategies based on specific use cases and requirements.

HP-UX IPSec also emphasizes interoperability and compliance with industry standards. The software supports various encryption algorithms and authentication methods, including those defined by the Internet Engineering Task Force (IETF). This commitment to open standards ensures that HP-UX can seamlessly integrate with a diverse range of networking infrastructures and security solutions.

In addition to its security features, HP-UX IPSec Software offers administration tools that simplify the configuration and management of IPSec policies. The software includes a user-friendly command-line interface, allowing system administrators to specify security associations and policies efficiently. Moreover, comprehensive logging and monitoring capabilities help organizations keep track of their security posture and detect potential vulnerabilities.

Another essential characteristic of HP-UX IPSec Software is its scalability. Designed to accommodate the needs of both small and large enterprises, it can handle increased loads and adapt to changing security demands without compromising performance.

In conclusion, HP-UX IPSec Software stands as a vital solution for organizations seeking to protect their data transmissions over IP networks. With its core technologies, such as transport and tunnel modes, adherence to industry standards, user-friendly administration tools, and scalability, it provides a formidable layer of security in an increasingly interconnected world. This makes it a preferred choice for enterprises aiming to enhance their network security frameworks.
