QuestionQ42

VerifiedInformation Security Concepts

Some bastion servers include auditing programs that check whether an attack has been launched against them. The checksum program can be used for auditing. The checksum is calculated from the size of an executable program installed on the server. This program computes the checksum to determine whether any modifications have occurred. Changes to the checksum indicate an attack.

What type of Bastion host is used to test new applications whose security flaws are not yet known and to run services that are not secure?

Explanation

A non-routing dual-homed host has separate network interfaces but does not forward traffic directly between the connected networks. This isolation makes it suitable as a bastion host for testing applications with unknown vulnerabilities and for operating insecure services without providing a direct routing path into the protected network.
