Question:
Derek is responsible for his organization's certificate authorities and aims to include a new certificate authority. His organization presently operates three certificate authorities in a mesh:
A. South American CA
B. the United States CA
C. the European Union CA.
As they expand into Australia, he wants to add D. the Australian CA. To enable systems in the Australian domain to access servers in the domains of A, B, and C, which certificate authorities (CAs) will Derek need to issue certificates from D?
A
He needs to issue certificates from D to each of the other CAs systems and then have the other CAs issue D a certificate.
explanation
It is crucial to note that the certificate authorities (CA) in this scenario are operating in a mesh, implying that no CA serves as the root CA, and each must trust the others. To achieve this, Derek must initially issue certificates from D to every other CA and then have the other CAs issue a certificate to D. Private keys must never be exchanged, and if only the other systems issue certificates to D, they will not recognize his server.
