Figure 14 Key Exchange Settings Dialog Box

Configure the fields as follows:

•Master key perfect forward secrecy (PFS)

Selecting this check box sets the maximum number of IPsec or Quick Mode (QM) negotiations that IKE can perform using an IKE SA to 1. It is equivalent to specifying -maxqm 1 in the ipsec_config add ike command. PFS is computationally expensive and HP recommends that you enable it only in hostile environments. See “Maximum Quick Modes” (page 43) and “Perfect Forward Secrecy (PFS)” (page 43) for more information.

•Authenticate and generate a new key after every: ____ minutes

This field specifies the maximum lifetime for an IKE SA in units of time. It is equivalent to the -lifeargument of the ipsec_add ike command.

TIP: Note that this value is specified in minutes on Windows systems and in seconds on HP-UX systems.

•Authenticate and generate a new key after every: ____ sessions

This field specifies the maximum QM negotiations per IKE SA. It is equivalent to the -maxqm argument of the ipsec_add ike command. See “Maximum Quick Modes” (page 43) and “Perfect Forward Secrecy (PFS)” (page 43) for more information.

Modify the values as appropriate. If you do not want to modify the IKE encryption, hash, or Diffie-Hellman Group parameters, click OK to return to the General dialog box and continue to the next step.

To modify IKE encryption algorithm, hash algorithm, or Diffie-Hellman Group parameters, click Methods. The IP Security configuration utility opens the Key Exchange Security Methods dialog box, which lists IKE algorithms and Diffie-Hellman Groups that correspond to IKE SA proposals in order of preference. You can change the order by using the Move up and Move down buttons. You can also delete IKE SA proposals (such as proposals that use DES, which has been cracked) using the Delete button.

To add another IKE SA proposal (method), click Add.

The IP Security configuration utility opens the IKE Security algorithms dialog box (Figure 15).

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.
