a) Bastion Host
b) Screened subnet
c) Screened host
d) Screened
Answer:
b) Screened subnet
Explanation:
In Computer science, Firewall implementation and design for an enterprise can be a daunting task. Choices made early in the design process can have far-reaching security implications for years to come.
Screened subnet firewall architecture is designed to host servers that offer public services.
In network security and management, one of the network architecture used by network engineers for the prevention of unauthorized access of data on a computer is a screened subnet. A screened subnet can be defined as a network architecture that uses a single firewall with three screening routers as a firewall.
<em>A screened subnet is also known as a triple-homed firewall, this is because it has three (3) network interfaces;</em>
1. Interface 1: it is known as the external or access router, which is a public interface and connects to the global internet.
2. Interface 2: it is known as the demilitarized zone or perimeter network, which acts as a buffer and hosted public servers (bastions host) are attached herein.
3. Interface 3: it is known as the internal router, which is a subnet that connects to an intranet.
<em>The screened subnet when properly configured helps to prevent access to the internal network or intranet. </em>
A- overusing highlights lowers the contrast and degrads the effect of the highlights.
Answer:
Question is incomplete. it needs a topology diagram and also it needs Router R1 table. I assume User has access to the topology and Routing table.
Below Configuration will help to fix ACL problem
Hosts from the 172.16.0.0/16 network should have full access to Server1, Server2 and Server3 but this is not currently the case, as L1 can’t communicate to Server2 or Server3.
Explanation:
Following Configuration on Cisco Router R1 will help to fix all the ACL problems.
