Hardware and software has changed significantly since CeRTNA's original launch in 2008. Since that time the CeRTNA ERDS application environment is transitioning from a simple web client application to a more sophisticated thick client application named APEX.

The following workstation specifications are designed to satisfy the requirements for running APEX and are current as of July 1, 2017:

• Processor: Intel i5
• Memory: 8 GB Minimum / 16 GB Recommended
• Disk Storage: Depends on your environment. (See note.)
• USB Port: Available USB 2.0 port
• Operating System: Windows 10 Professional (x64)

Notes:

• The CeRTNA ERDS workstation will need to have network access to the shared folder or UNC path where the CeRTNA ERDS XML transactions will be accessed for submissions, stored upon retrieval, and or picked up for return. Please refer to the section Folder Structure in the Workstation Installation Guide for a description of how the standard CeRTNA ERDS folder structure should be created.

• You will need a security cabinet for your ERDS workstation. You can click this link to see a security cabinet that CeRTNA recommends.

When CeRTNA was originally launched, the Windows XP environment was supported. Since that time, Microsoft has ended support for Windows XP and therefore CeRTNA will no longer certify Windows XP workstations.

CeRTNA will certify and support the CeRTNA ERDS application and the required tools on Windows 7 Professional or Windows 10 Professional (32-bit or 64-bit versions). If possible, CeRTNA recommends using Windows 10 Professional for APEX installations. Windows 10 Home Edition is not supported because it does not have support for Local Security Policy.

APEX communicates using SSL. The following table contains a list of hosts that must be reachable in order for APEX to be installed or be used after the installation:

CeRTNA recognizes that different firewalls are in service at our customers and that firewall features functions can vary broadly. CeRTNA prefers to minimize the amount of IT administrative by creating rules based on the following tolerance and/or capabilities of your firewall:

• Use wildcard domains if possible. (Ex: *.certna.org or *.certnag2g.org)
• Use host names if possible. (Ex: apex-prd.certna.org or reports.certna.org)
• Last resort, use IP addresses. (This is the least preferred.)

The preceding list is sorted in order of preference.
