1. A. Perimeter security is intended to delay or deter entrance into a facility. Mantraps are used for mid-layer access control to prevent tailgating. Multifactor authentication is used for mid- and inner-layer access control. Strong passwords are used for mid- and inner-layer access control.

Disabling DNS will limit all hosts on a network from getting to the Internet and will not limit network access. A default subnet mask will not limit network access and will cause other problems. An empty default gateway will not limit network access.
3. A. Social engineering uses the inherent trust in the human species, as opposed to technology, to gain access to your environment. IDS systems are network-based systems that detect intrusions. Perimeter security...
