A. B. C. D.D.
Out of the given options, configuring IPSec would be the best solution to meet the requirement of private communication between the application team and the administrator's team.
IPSec (Internet Protocol Security) is a set of protocols that provide security services for IP-based communication. IPSec can be used to encrypt data and ensure the integrity of the communication between two hosts.
When IPSec is configured between the two hosts, all data between them is encrypted, and only the authorized hosts can decrypt the data. This provides a secure and private communication channel between the application team and the administrator's team.
On the other hand, a NIDS (Network Intrusion Detection System) is a security solution that monitors network traffic for potential threats and attacks. While it can alert the administrator of any malicious activity, it does not provide a private communication channel between the two teams.
Enabling a host-based firewall would provide a certain level of security by blocking unwanted traffic to the server, but it does not ensure private communication between the two teams.
A RADIUS (Remote Authentication Dial-In User Service) server is used for authentication and authorization of remote users accessing network resources. While it can help in ensuring secure access to the server, it does not provide a private communication channel between the two teams.
Therefore, configuring IPSec would be the best solution to meet the requirement of private communication between the application team and the administrator's team.
