To apply a Tenable Security Center patch manually:

  1. Download the patch TGZ file from the Tenable downloads page. If necessary, depending on the operating system of the host, move the upgrade TGZ file onto the host.

  2. Confirm the integrity of the patch TGZ file by comparing the download checksum with the checksum on the Tenable downloads page.

  3. If your organization requires Tenable Security Center to use /dev/random instead of /dev/urandom to generate random number data for secure communication functions, modify the random data source as described in Use /dev/random for Random Number Data Generation.

  4. Access the command line as a user with root-level permissions.

  5. Run the following command to untar the patch file, where [patch file name] is the name of the TGZ patch file you downloaded:

    tar zxf [patch file name]

  6. Run the following command to change the directory to the extracted directory, where [directory] is the extracted directory:

    cd [directory]

  7. Run the following command to begin the installation:

    sh ./install.sh

    The installation begins and Tenable Security Center stops. After the installation finishes, Tenable Security Center automatically restarts.

  8. (Optional) Confirm the patch successfully applied to Tenable Security Center, as described in the knowledge base article.
