In an effort to secure communication for an internal-facing web service, a system administrator has been tasked with implementing an encrypted connection protocol. External validation of the server's identity by outside entities is not a requirement due to the service being exclusively accessed within the organization. What is the most appropriate action for the administrator to undertake?
Obtain and install a certificate from a recognized certificate authority.
Rely on secure shell protocols for encrypted web traffic, circumventing the need for certificates.
Procure a domain-validated certificate and apply it to the web service.
Create and configure a certificate signed by the server's private key.
Operate the web service without encryption since it is internally accessed and does not need protection.
Activate encrypted connections without a certificate, as internal services do not require authentication.
