Routers

about with devices such as: a Laptop, PDA, Mobile Phone and a tablet etc. You can move all around a home, anywhere really depending on the range of the signal. WLAN came about in the early 90s but was very expensive so you wouldn’t have a wireless router in your home back then. It wasn’t till the late 90s when it began to become cheaper. Most WLAN and proprietary protocols were using IEEE 802.11 either 802.11A through to 802.11N, prices for this declined rapidly making it more affordable. What…

The purpose of this paper is to describe the network configuration, explaining the role of each component and connection of the scenario provided. Specifically, I will discuss the functions of the components and describe how they contribute to the network. Along with this I will modify the appropriate components of the provided database with the information regarding the employees’ computers and the upgrade. Network Configuration Network configuration allows a system admin to set up a network…

UML 91.561 Computer & Network Security I HomeWork 1 Name – Nrupen Abnave Student ID -01382247 1.1 (a) Describe the major structure of a TCP packet and explain the main functions of the TCP headers. - TCP is a transport layer protocol and is connection oriented. Its reliable connection, has error checking and flow control. TCP Headers: 32bits Source and Destination Ports – Each 16bit number. Indicate which application is using the communicating stream. Used by most common…

This diagram illustrates a Local Area Network implemented using an Ethernet connection on a bus topology model. It is a LAN because there is no indication of considerable distance between the computers or departments. It is in Bus topology as since the computers connect to the network by connecting to the network cable. This as opposed to a star network topology setup. Next to each network component is an Internet Protocol (IP) address. Each IP consists of four number whose value can range from…

Every program or every collection of programs implementing a single business function must have unique database credentials. Sharing of credentials between programs is not allowed. Database passwords used by programs are system-level passwords as defined by the Password Policy. Developer groups must have a process in place to ensure that database passwords are controlled and changed in accordance with the Password Policy. Authorized Networked Devices Policy: The security features necessary to…

This week assignment was a little confusing because I have never done a diagram with a computer software. Even though creating a diagram on a computer looks easy to do, it is different when you must make sense of it and guide people to understand it. Before I decided to choose a program, I went ahead and drew a draft of the network diagram with pen and paper. I sketched the diagram so I can have an idea of where to start and what I wanted to reflect on my final draft. Then I proceeded to use…

1: Examine the Header Fields in an Ethernet II Frame What is significant about the contents of the destination address field? It starts with the broadcast ARP protocol from the router asking who has 192.168.2.22. Then it starts showing the source ip address then destination addresses then rebroadcasting from your router. ____________________________________________________________________________________ ____________________________________________________________________________________…

To setup the VPN client you will need a Cisco ASA router that support the Cisco any connect client. The Cisco ASA router will be enabled and configured to accept per user base VPN connection and will allow the user access with the correct authenticated login credentials. The Cisco any connect client will allow a secure SSL connection…

your privacy. Long story short: a light browser version sometimes means more security vulnerabilities. The use of 3G in smartphones also means more people are connected to the same radio tower. Compare this to a private WiFi network with a private router that only has to serve a few people. So this automatically means that if a tower is compromised it covers more customers who lose their privacy. And as this data is kept by companies like KPN you are in luck if you never live through such a…
