This page documents specific steps on specific Operating Systems to enable FIPS support which is available from Opsview Monitor 6.5.4.
While the rest of the Opsview system will happily work on a FIPS enabled server running RedHat Enterprise Linux 8 (RHEL 8), the Opsview Reporting Module requires a Java Runtime configured to not run in FIPS mode due to the incompatibility with FIPS standards that the keystore algorithm (JCEKS) Jasperserver uses.
There are two workarounds to this issue:
- Install a new JRE just for Opsview to run in a non-FIPS compliant mode. This will allow any other Java applications on the system to continue running in FIPS mode while allowing the Reporting Module to run.
- Configure the currently installed JRE on the Orchestrator machine to run in a non-FIPS compliant mode. This will have the side effect of allowing non-FIPS compliant Java applications on the system.
Note that if there is no Java runtime located on the orchestrator machine, one of the workarounds must be performed so that the Reporting Module has a valid Java installation to use.
Note: these instructions will need to be modified if a later version of the JRE is released
- Get the URL of the latest 1.8 OpenJDK release from Red Hat.
- Download the OpenJDK tarball from the above site and transfer it to the Orchestrator host
scp java-1.8.0-openjdk-<version>.portable.jre.el.x86_64.tar.xz orchestrator-hostname:/tmp/
- Create the Opsview Java directory
- Extract the OpenJDK tarball in the newly created Java directory
tar -xf /tmp/java-1.8.0-openjdk-<version>.portable.jre.el.x86_64.tar.xz -C /opt/opsview/java --strip 1
- Set security.useSystemPropertiesFile to false in the new Java installation’s java.security file
sed -i.bk "s/^security.useSystemPropertiesFile=true/security.useSystemPropertiesFile=false/g" /opt/opsview/java/lib/security/java.security
- Run the check-deploy playbook to ensure that Java is now correctly configured. Note that from 6.6.5 onwards this playbook will additionally set up python on all systems used.
Please note that this Java install is currently not managed by Opsview in any way. This means that any security updates will have to be manually installed by rerunning the manual steps listed above.
- Run the check-deploy playbook in Opsview Deploy. This will detect the Java runtime that Jasper server will choose to use and raise an alarm if it is not configured as needed. (Note that from 6.6.5 onwards this playbook will additionally set up python on all systems used).
cd /opt/opsview/deploy/ ./bin/opsview-deploy ./lib/playbooks/check-deploy.yml .... REQUIRED ACTION RECAP ******************************************************************** [HIGH -> rm-op-44104-rhel8-2-orch] Security flag is set to 'true' on system Java | A system Java Runtime (JRE) installation has been located at | /usr/lib/jvm/jre-1.8.0-openjdk, but the security flag 'security.useSystemPropertiesFile' | is currently set to 'true'. | | In order to use the Opsview Reporting module on RedHat 8 with FIPS mode enabled, | this flag must either be set to false or an alternative Java installation | installed for Opsview's usage. | | For more information and instructions, see: | https://knowledge.opsview.com/docs/
- Edit the configuration file in the specified Java directory. The following sed command creates a backup named java.security.bk.
# In this example, the Java directory is '/usr/lib/jvm/jre-1.8.0-openjdk' as specified by the Deploy in the `REQUIRED ACTION RECAP` output cd /usr/lib/jvm/jre-1.8.0-openjdk/ sed -i.bk "s/^security.useSystemPropertiesFile=true/security.useSystemPropertiesFile=false/g" lib/security/java.security
- Rerun the check_deploy playbook as per step 1 to ensure that Java is now correctly configured.
Opsview Agent Deprecation
The Opsview Agent and the steps below are now deprecated, and we instead recommend use of the ITRS Infrastructure Agent which works by default in a RHEL8 FIPS environment.
The default anonymous ciphers configured on the Orchestrator and used to communicate with
opsview-agent on monitored devices need to be replaced with higher security ones in order for
check_nrpe based checks to work in a RHEL8 FIPS environment. The easiest way to accomplish this is to replace the ciphers listed in the
NRPE_CIPHERS global variable (Menu => Configuration => Advanced => Variables) with
AECDH-AES256-SHA:AECDH-AES128-SHA and run an
Customers need to ensure that the
opsview-agent on the monitored hosts allows this new cipher configuration (see Opsview Agent Security for more details) - they will work with all recent versions of the
opsview-agent (v6.0.0 and newer) using the default configuration. This change is not necessary if customers already use authenticated ciphers exclusively.
The need for this change is brought about by the tighter security standards enforced by RHEL8 FIPS ( see Strong crypto defaults in RHEL 8 and deprecation of weak crypto algorithms - Red Hat Customer Portal ). These new ciphers make use of Elliptic-Curve Cryptography (ECC) which provides enhanced security as well as improved performance.
