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.
The HCL® Informix® Security Guide documents 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.
Use network encryption to encrypt data transmitted between server and client, and between server and other server.
This topic offers some generic insights into keystores and how they are used for secure communications with the TLS (Transport Layer Security) protocol. While the first part provides the theoretical background, the second part shows examples for applying this in practice using OpenSSL.
Welcome to the documentation for HCL Informix® 15.0.0 and related client tools and products.
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.
These topics describe how to install HCL Informix® database servers, client products, and modules.
In addition to administering the database server, you can tune performance, replicate data, and archive data.
You can upgrade to the 15.0.0 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.
You can use the HCL Informix® implementation of client APIs to develop applications for Informix database servers.
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.
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 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.
In addition to designing and implementing Informix® dimensional databases, you can use tools to create data warehouse applications and optimize your data warehouse queries.
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.
You can use the popular JSON-oriented query language created by MongoDB to interact with data stored in HCL Informix®.
utilities and product directories are secure by default.
You can use the communication support modules (CSMs) to encrypt data transmissions, including distributed queries, over the network.
You can configure network data encryption for Enterprise Replication and high availability clusters by using configuration parameters.
This section explains keystores for TLS/SSL (Transport Layer Security / Secure Socket Layer) connections between database clients and servers.
You can use column-level encryption to store sensitive data in an encrypted format. After encrypting sensitive data, such as credit card numbers, only users who can provide a secret password can decrypt the data.
You can administer the security of the connections to the database server by using authentication and authorization processes.
Discretionary access control verifies whether the user who is attempting to perform an operation has been granted the required privileges to perform that operation.
You can use label-based access control (LBAC), an implementation of multi-level security (MLS), to control who has read access and who has write access to individual rows and columns of data.
You can use the HCL Informix® implementation of the SQL language to develop applications for Informix database servers.
Several troubleshooting techniques, tools, and resources are available for resolving problems that you encounter in your HCL Informix® database server environment.
