Database encryption allows individual attributes to be encrypted as they are stored in the database. When configured, every instance of a particular attribute, even index data, is encrypted and can only be accessed via a secure channel, such as SSL/TLS.

For information on using database encryption, refer to the "Configuring Directory Databases" chapter in the HP-UX Directory Server administrator guide.

8.9 Securing server to server connections

After designing the authentication scheme for identified users and the access control scheme for protecting information in the directory, to design a way to protect the integrity of the information passed between servers and client applications.

For both server to client connections and server to server connections, the Directory Server supports a variety of secure connection types:

•Secure Sockets Layer (SSL) and Transport Layer Security (TLS)

To provide secure communications over the network, the Directory Server can use LDAP over the Secure Sockets Layer (SSL) or Transport Layer Security (TLS).

SSL/TLS can be used in conjunction with the RC2 and RC4 encryption algorithms from RSA. The encryption method selected for a particular connection is the result of a negotiation between the client application and Directory Server.

•Start TLS

Directory Server also supports Start TLS, a method of initiating a Transport Layer Security (TLS) connection over a regular port.

•Simple Authentication and Security Layer (SASL)

SASL is a security framework, meaning that it sets up a system that allows different mechanisms to authenticate a user to the server, depending on what mechanism is enabled in both client and server applications. It can also establish an encrypted session between the client and a server. In Directory Server, SASL is used with GSS-API to enable Kerberos logins and can be used for almost all server to server connections, including replication, chaining, and pass-through authentication. (SASL cannot be used with Windows Sync.)

NOTE:

SASL encryption is not supported for client connections that use SSL/TLS.

Secure connections are recommended for any operations which handle sensitive information, like replication, and are required for some operations, like Windows password synchronization. Directory Server can support SSL/TLS connections and non-SSL connections simultaneously.

For more information about using SSL/TLS, Start TLS, and SASL, check out the Administrator's Guide.

UX Direry Server specifications

HP UX Directory Server is a robust and scalable solution designed for managing directory information within enterprise networks. Developed by Hewlett-Packard (HP), this server offers an extensive set of features tailored to meet the needs of organizations that require an efficient way to store, manage, and retrieve identity and access data.

One of the key features of HP UX Directory Server is its ability to handle large directories with significant volumes of data. Built on a highly optimized architecture, it provides excellent performance and can support millions of entries without sacrificing speed or reliability. This capability makes it an ideal choice for large-scale deployments in enterprises that require high availability and responsiveness.

In addition to its scalability, HP UX Directory Server supports a wide range of protocols, including LDAP (Lightweight Directory Access Protocol), which ensures seamless integration with diverse applications and systems across various platforms. The server maintains standards compliance, which facilitates interoperability and simplifies administration tasks.

Security is a top priority for HP UX Directory Server, offering an array of features to protect sensitive information. It supports secure data transmission via TLS/SSL protocols, ensuring encrypted communication between clients and servers. Advanced access controls allow administrators to define fine-grained permissions, helping to safeguard directory data against unauthorized access.

Another salient feature of HP UX Directory Server is its replication capabilities. The server can replicate directory data across multiple instances, ensuring data consistency and availability in distributed environments. This feature is essential for businesses operating across different geographical locations or requiring failover solutions for disaster recovery.

HP UX Directory Server also comes equipped with tools for data management, including an intuitive administration console for configuring and monitoring the server. Additionally, it offers customizable schema capabilities, enabling organizations to tailor the directory structure to fit their specific needs.

Integration with existing identity management solutions is streamlined through connectors and APIs, allowing organizations to extend their directory services and enhance user experience.

In summary, HP UX Directory Server is a powerful directory management solution that combines scalability, security, and integration flexibility. Its support for industry standards, advanced replication, and comprehensive administrative tools makes it an essential asset for organizations seeking to manage identity and access efficiently. By leveraging this technology, businesses can improve their operational efficiency and ensure a secure and organized approach to directory management.
