Layer 6: Presentation - Layer 6 takes the data provided by the Application layer and converts it into a standard format that the other layers can understand.

TACACS+ (Terminal Access Controller Access-Control System), it uses TCP Protocol and Port 49. Also it encrypts the entire payload and separates Authentication & Authorization.

The same implementation should be made for the server as well. In the server's case the firewall placed between it and any client should limit the quantity of connection from a source IP. The unfortunate side of this, and why the client firewall be implemented, is that many clients can be located behind one source IP address. This means that the server's firewall configuration needs to be more lenient the the client firewall.

The protocol can authenticate both the client and the server (mutual authentication) oronly one party.In the server-authenticated mode, the client can still authenticate it-self by anothermethod such a login/password authentication. All data exchanged are encrypted.HTTPS is commonly used to secure transactions on the Internet. Therefore, it is widelysupported by web browsers and network software libraries. Being a different protocol thanHTTP, it typically uses a different port (443).

through and what does not and can be customized to be more or less secure. Firewalls are

Each IP that accesses the internet will be under a NAT protocol to help protect the users accessing the internet.

I have chosen the three-tier design, the user interface runs on the client and the data is stored on the server. A three-tier design also has a middle layer between the client and server that processes the client requests and translates them into data access commands (Shelly-Rosenblatt, 2012).

Jim Crow laws does not play a role really in today's time, but there is still some racial problems. Predominantly white schools sometimes have better education systems, and get paid more on a job than any other race. Sometimes mostly black/Hispanic (lower) communities look nicer than a community with mostly white or higher income communities.

Intelligence and Power. These two concepts are closer than most think. Many political figures use their intelligence to get their position in society. However, many use their intelligence for the sake of themselves and not for others. Their intelligence is what lead them to power and power is what polluted their mind.

2. How would you instruct an Apache server to listen on Port 81 instead of Port 80?

As seen in the figure, functional structure comprising top level management is embedded in levels 1-3. The geographical divisions are embedded in level 4. Product divisions are embedded in levels 5-7 and the frontline teams, the teams at level 8.

Firewall: A firewall is a software or hardware-based network security system that controls the incoming and outgoing network traffic by analysing the data packets and

“Imagine a person on a desktop computer who uses Microsoft Access to load up a list of personal addresses and phone numbers that he or she has saved in MS Windows “My Documents” folder. This is an example of a one-tier database architecture” (Windowsecutity.com) “A two tier client/server architecture is one in which a user interacts through a Graphical User Interface to communicate with the database server across a network via Structured Query Langauage.” (Windowsecurity.com) Last is an N-Tier Clinet/Server Architecutre. “Most n-tier database architectures exist in a three-tier configuration. In this architecture the client server model expands to include a middle tier (business tier) which is an application server that houses the business logic. This middle tier relieves the client application and the database server of some of their processing duties by translating client calls into database queries and translating data from the database into client data in return.” (windowsecurity.com)

There are several ways to build up an intranet. However some common characteristics of an intranet’s architecture, in order for organizations to gain the more out of it, are:

A firewall is a system or group of systems that enforces an access control policy between two or more networks. The means by which this control is accomplished varies widely, but in principle, the firewall is a pair of mechanisms, one that blocks traffic and one that permits traffic. Some firewalls emphasize blocking traffic, while others emphasize permitting traffic. The most important thing to recognize about a firewall is that it implements an access control policy. If you don't know what kind of access you want to permit or deny, or you let someone else or some product configure a firewall based on judgment other than yours, that entity is making policy for your whole organization.
