Hardened Hosts for Authorized Users | CCSP Exam | isc

B.

A bastion host is a server that is fully exposed to the public Internet, but is extremely hardened to prevent attacks and is usually dedicated for a specific application or usage; it is not something that will serve multiple purposes.

This singular focus allows for much more stringent security hardening and monitoring.

The correct answer to the question is option B, "Bastion."

A bastion host is a specific type of host that is exposed to the public internet for a specific reason, and it is hardened to perform only that function for authorized users. The main purpose of a bastion host is to provide secure access to a private network from an external network such as the internet.

Bastion hosts are commonly used in environments where secure access to a private network is required for remote system administration or for accessing sensitive data. For example, a company might use a bastion host to allow remote access to a corporate network from a public Wi-Fi hotspot.

To ensure the security of the bastion host and the private network it provides access to, the bastion host must be hardened. This means that unnecessary services and protocols should be removed or disabled, and only the required services and protocols should be enabled. Additionally, access to the bastion host should be restricted to authorized users and protected with strong authentication mechanisms such as multi-factor authentication.

In summary, a bastion host is a specially configured and secured server that is placed between an external network and a private network to provide secure access to the private network from the external network.
