Fix Recommendation

A server certificate must be installed on each Linux VDA server and root certificates must be installed on each Linux VDA server and client.
Obtain server certificates in PEM format and root certificates in CRT format from a trusted CA. A server certificate contains the following sections:
- Certificate
- Unencrypted private key
- Intermediate certificates (optional)

After obtaining required certificates, customers need to install them as follows:
Upload server and CA certificates into Linux VDA server, which will be used in “Step 2: Enable SSL encryption on Linux VDA”. For example, put server.pem (name of server certificate) and myca.crt (name of CA certificate) to folder /root/myCert/myCA/certs/.

Download the CA certificate (myca.crt as an example) to client host and import it into system Certificate Store on the “Trusted Root Certification Authorities” folder. Refer to "Importing Trusted CA Certificates into the Windows Certificate Store" for the instructions. Note: Ensure the client host is able to resolve the FQDN of Linux VDA; otherwise, the connection cannot be established.

Check Contents

Verify the correct server certificate issued by authorized certificate authority is installed on Linux VDA.
Navigate to folder /root/myCert/myCA/certs/ and examine certificates.
If the certificates are not issued by the DoD or approved CA, this is a finding.
