Security Center 3.4.3 Release Notes

Note: A recorded webinar by Tenable founder, Ron Gula on the Security Center 3.4.3 features is available.

The following list describes many of the changes that are included in Security Center version 3.4.3, the significant issues that have been resolved as well as notes for upgrading. A PDF file of these release notes is also available here.

Upgrade Notes

General Notes

As with any application, it is always wise to perform a backup of your Security Center installation before upgrading.

Upgrading from 3.4.0

There are no special upgrade related notes. The command syntax for an RPM upgrade is as follows:

    rpm -Uvh <RPM Package File Name>

Compatibility with other Tenable software

There are a number of new features in SC 3.4.3, LCE 3.0.1 and the LCE 3.x clients that are only available if all three products are running the software versions that support the new features. The products will function together if they are not all upgraded, but some of the new features may not be available.

Upgrading from Pre-3.4.0 Security Center Versions

  • Please note that existing scan policies, as well as scheduled and template scan files will be modified as part of the update process. Please be sure to verify these files after the upgrade.
  • After upgrading to Security Center 3.4.x you may experience a problem with the display of the text of tickets that are entered. The issue manifests when a single quote (') is used in the text of the ticket, in which an escape character (\) is added.

    For Example: "This is the vulnerability that John\'s team was worried about."

    The file /opt/sc3/support/etc/php.ini does not get updated by the upgrade process in order to protect any modifications that you have made. To correct this, edit the file and change the line that reads "magic_quotes_gpc = On" to "magic_quotes_gpc = Off". Restart the HTTPD services (use the command "service httpd restart") and the issue should be resolved. New installations of Security Center will have this setting off by default.
  • Security Center v3.4 is the first version in which the Red Hat ES 5 operating system is supported. Existing SC customers wishing to migrate their installations to ES 5 must first upgrade their current installation of SC to v3.4.x, then follow the OS migration procedures as documented in the Cerberus knowledge base article titled "Retaining Security Center 3 install when installing new OS".
  • All release notes for Security Center versions 3.4.0 and later are applicable and should be reviewed. These release notes may be found on the Tenable Customer Support Portal, in the Downloads section, under the Security Center portion of the Security Center, 3D Tool and xTool page.

Scanning/Scan Policies

  • Credentialed scans on Unix/Linux target hosts now have the ability to elevate privileges via su/sudo.

  • A new configuration option has been added to allow Security Center administrators to define the interval in which SC resynchronizes with its Nessus scanners. This is most relevant to large SC installations with many Nessus scanners from which very frequent or constant scanning is performed.
  • Facility for SC administrators to "Reset" the Nessus plugins activation code has been added for ease of code replacement and troubleshooting connectivity issues.
