When FIPSMode is enabled, InterSystems IRIS® data platform uses the FIPS 140–2 compliant library for database encryption on Red Hat Enterprise Linux 6.6 (or later minor version) and Red Hat Enterprise Linux 7.1 (or later minor version) for x86-64.
Enabling FIPSMode only affects encrypted databases. To encrypt a database, choose the Encrypt Database? option during the database creation process.
See the article FIPS 140–2 Compliance for Database Encryption for details.
Changing This Parameter
On the Startup page of the Management Portal (System Administration > Configuration > Additional Settings > Startup), in the FIPSMode row, select Edit. Select FIPSMode to use the FIPS 140-2 compliant library for database encryption.
Instead of using the Management Portal, you can change FIPSMode in the Config.StartupOpens in a new tab class (as described in the class reference) or by editing the CPF in a text editor (as described in the Editing the Active CPF section of the “Introduction to the Configuration Parameter File” chapter in this book).
