The IP Security configuration utility opens a Filter Properties dialog box.

2.Select the Addressing tab in the Filter Properties dialog box. Use the drop-down menus to specify the address types for the source and destination addresses. The selections are:

•My IP Address1

•Any IP Address

•A specific DNS Name

•A specific IP Address

•A specific IP Subnet

Enter the source and destination IP addresses or DNS names for the filter. If you selected A specific IP Subnet, enter the subnet mask.

WARNING! Be careful when configuring filters that affect packets required for basic network operation, such as packets exchanged with DNS servers and ICMP packets exchanged with routers. If you configure a policy that requires IP Security for these packets and the remote node does not support IP Security, your system can lose network functionality.

Leave the Mirrored check box selected, which creates a bi-directional filter that applies to packets to and from the destination system. See “Mirrored Filters” (page 41) for more information about mirrored filters.

In Figure 5, the administrator specifies an address filter with the Windows system address (10.1.1.1) as the source address and the HP-UX system address (10.2.2.2) as the destination address. The Mirrored check box is selected, so the address filter also matches packets from the HP-UX system.

3.Select the Protocol tab in the Filter Properties dialog box. By default, the filter applies to all protocol types. Select the protocol type (for example, TCP) from the drop-down box. If you select TCP or UDP, you can also specify the From (source) port and To (destination) port.

Click OK to return to the Filter Properties dialog box.

1.HP-UX did not test the My IP Address selection with multihomed Windows systems. However, the Windows documentation states that in a multi-homed system, My IP Address matches every IP address on the system.

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.
