Configuring HP-UX IPSec

Step 2: Configuring Tunnel IPSec Policies

Complete this step only if you are using IPSec tunnels. If you are not using IPSec tunnels, continue to “Step 3: Configuring IKE Policies” on page 89.

Tunnel IPSec policies specify HP-UX IPSec behavior for IP packets tunneled by the local system. In an IPSec tunnel, a tunnel endpoint system encapsulates the original packet in a new IPSec packet with an AH or ESP header. The other tunnel endpoint system processes the AH or ESP header, decapsulates the packet, and sends the packet to the destination address in the original packet header.

An HP-UX system can be the end host in a host-to-host tunnel topology, or the end host in a host-to-gateway tunnel topology.

If the system is an HP-UX Mobile IPv6 Home Agent, it can also act as a gateway, but only when forwarding packets between a Mobile IPv6 client and its Correspondent Node. See “HP-UX IPSec and HP-UX Mobile IPv6” on page 199 if you are configuring HP-UX IPSec for Mobile IPv6.

Tunnel IPSec policies are referenced in host or gateway IPSec policies. HP-UX IPSec first selects a host or gateway IPSec policy to use for a packet. If the IPSec policy specifies a tunnel policy, HP-UX IPSec uses the information in the tunnel IPSec policy to establish an IPSec tunnel with the tunnel destination.

If the local system is a tunnel endpoint, you must configure tunnel IPSec policies. HP recommends that you use an ipsec_config batch file to configure tunnel IPSec policies.

ipsec_config add tunnel Syntax

If you are not using manual keys, you can use the following ipsec_config add tunnel syntax in most installations:

ipsec_config add tunnel tunnel_policy_name

-tsourcetunnel_address -tdestinationtunnel_address [-sourceip_addr[/prefix][/port_numberservice_name]]]

[-destinationip_addr[/prefix][/port_numberservice_name]]]

[-protocolprotocol_id] [-actiontransform_list]

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.
