Welcome
Security
You can secure your Informix® database server and the data that is stored in your Informix databases. You can encrypt data, secure connections, control user privileges and access, and audit data security.
Security in HCL Informix®
These topics document methods for keeping your data secure by preventing unauthorized viewing and altering of data or database objects, including how to use the secure-auditing facility of the database server.
Auditing data security
Auditing with Security Guardium® (UNIX, Linux)
You can audit user actions for your Informix® database server with Security Guardium® version 10.0 or later. Security Guardium prevents leaks from databases, ensures the integrity of information, and automates compliance controls across heterogeneous environments.

HCL Informix® V14.10 documentation
Welcome to the documentation for HCL Informix® 14.10 and related client tools and products. The current fix pack level of Informix is 14.10.xC13.
Product overview
HCL Informix® is a fast and scalable database server that manages traditional relational, object-relational, and dimensional databases. Its small footprint and self-managing capabilities are suited to embedded data-management solutions.
Installing
These topics describe how to install HCL Informix® database servers, client products, and DataBlade® modules.
Administering
In addition to administering the database server, you can tune performance, replicate data, and archive data.
Migrating and upgrading
You can upgrade to the 14.10 release of HCL Informix® or migrate from other database servers to Informix. Upgrading is an in-place migration method that uses your existing hardware and operating system software. Some changes to the Informix database server can affect upgrading from a previous release.
Client APIs and tools
You can use the HCL Informix® implementation of client APIs to develop applications for Informix database servers.
Embedding Informix®
When you embed HCL Informix®, you can use enterprise-class high-availability and high performance with embeddability features such as easy programmability, a small disk and memory footprint, and silent deployment.
Extending Informix®
Beyond standard relational database objects, HCL Informix® can be extended to handle specialized data types, access methods, routines, and other objects. Informix includes many built-in extensions that are fully integrated in the database server. Informix also provides DataBlade® modules, which are packages of extended database objects for a particular purpose and that are installed separately from the database server. Alternatively, you can create your own user-defined objects for Informix.
Data warehousing
In addition to designing and implementing Informix® dimensional databases, you can use tools to create data warehouse applications and optimize your data warehouse queries.
Designing databases
The first step in creating a relational database is to construct a data model, which is a precise, complete definition of the data you want to store. After you prepare your data model, you must implement it as a database and tables. To implement your data model, you first select a data type for each column and then you create a database and tables and populate the tables with data. You can also implement fragmentation strategies and control access to your data.
JSON compatibility
You can use the popular JSON-oriented query language created by MongoDB to interact with data stored in HCL Informix®.
Security
You can secure your Informix® database server and the data that is stored in your Informix databases. You can encrypt data, secure connections, control user privileges and access, and audit data security.

        Use the ifxguard utility commands start, stop, and configure auditing.
      - IFXGUARD configuration parameter
        The IFXGUARD configuration parameter enables auditing with Security Guardium® and sets the actions of the database server if the Security Guardium server does not respond in the timeout period.

    - The onaudit utility
      Use the onaudit utility to manage audit masks and auditing configuration.
    - The onshowaudit utility
      Use the onshowaudit utility to view the audit information from an existing audit trail. You can use this command to extract information for a particular user, database server, or both, making it possible to isolate a particular subset of data from a potentially large audit trail.
    - Audit event codes and fields
      The secure-auditing facility audits certain database server events.

SQL programming
You can use the HCL Informix® implementation of the SQL language to develop applications for Informix database servers.
Troubleshooting HCL Informix®
Several troubleshooting techniques, tools, and resources are available for resolving problems that you encounter in your HCL Informix® database server environment.

Auditing with Security Guardium® (UNIX, Linux)

You can audit user actions for your Informix® database server with Security Guardium® version 10.0 or later. Security Guardium® prevents leaks from databases, ensures the integrity of information, and automates compliance controls across heterogeneous environments.

After you set up the Security Guardium® server, you start the ifxguard utility to monitor connections to your Informix® databases. You can set the logging mode and the number of worker threads to prevent heavy locking by editing the ifxguard configuration file. You can enable auditing and set the actions of the database server if the Security Guardium® server does not respond in the timeout period by setting the IFXGUARD configuration parameter in the onconfig file.

Every time a user session attempts an action that is auditable, an ifxguard agent contacts the Security Guardium® server. The Security Guardium® server can mask sensitive data or close a connection that fails the security audit.

To configure Security Guardium® and start auditing:

Install and configure Security Guardium®. See .
Edit the ifxguard configuration file.
Set the IFXGUARD configuration parameter in your onconfig file for your Informix® database server.
Follow the instructions in the section Informix EXIT with UNIX S-TAP to configure and start the ifxguard utility. See Installing an S-TAP on a UNIX server.
