SecurityCenter Software Requirements

All SecurityCenter versions require an active SecurityCenter license and OpenJDK or Oracle Java JRE. Operating system requirements depend on your SecurityCenter version:

SecurityCenter Version Operating System Requirements
5.7.0 and later
  • Red Hat Enterprise Linux 6 (64-bit)
  • Red Hat Enterprise Linux 7 (64-bit)
  • CentOS 6 (64-bit)
  • CentOS 7 (64-bit)
5.6.x and earlier
  • Red Hat Enterprise Server 5 (64-bit)
  • Red Hat Enterprise Server 6 (64-bit)
  • Red Hat Enterprise Server 7 (64-bit)
  • CentOS 5 (64-bit)
  • CentOS 6 (64-bit)
  • CentOS 7 (64-bit)

SELinux policy configuration is supported by Tenable in a “Permissive” mode.

Other SELinux modes are known to work, but the required configuration varies based on policies and custom configurations that may be in place on-site. It is strongly recommended that SELinux implementation configurations are tested prior to deployment on a live network.


Either OpenJDK or the Oracle Java JRE along with their accompanying dependencies must be installed on the system along with any additional Java installations removed for reporting to function properly.

Although it is possible to force the installation without all required dependencies, if your version of Red Hat or CentOS is missing certain dependencies, this will cause problems that are not readily apparent with a wide variety of functions. Tenable’s Support team has observed different types of failure modes for SecurityCenter when dependencies to the installation RPM are missing. If you require assistance or guidance in obtaining these dependencies, please contact our Support team at

The following programs must be installed on the system prior to installing the SecurityCenter package. While they are not all required by the installation RPM file, some functionality of SecurityCenter may not work properly if the packages are not installed. The packages listed below are among those that are most often not installed by default:

  • java-1.7.0-openjdk.x86_64 (or the latest Oracle Java JRE)
  • openssh
  • expat
  • gdbm
  • libtool
  • libtool-ltdl
  • libxml2
  • ncurses
  • readline
  • compat-libstdc++
  • libxslt

Using the latest stable production version of each package is recommended.
