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?
Rely on secure shell protocols for encrypted web traffic, circumventing the need for certificates.
Operate the web service without encryption since it is internally accessed and does not need protection.
Obtain and install a certificate from a recognized certificate authority.
Procure a domain-validated certificate and apply it to the web service.
Create and configure a certificate signed by the server's private key.
Activate encrypted connections without a certificate, as internal services do not require authentication.
