This proposal is for a small office that will have users who are connected by Wi-Fi or cable. The network will include devices and resources that is shared among all the users. The network will need to have security measures in place to protect the entire network and keep the wireless access secure and available only to employees of the company. I would suggest conducting a site survey before finalizing a network layout. A site survey will aid with determining where the wireless access points will be placed to give reliable coverage. Interference from other wireless networks could cause connectivity issues and the amount of square footage throughout the office space may also cause issues if the wireless access points are not planned out properly. Once the site survey is concluded any connectivity issues will be addressed and a solid network plan will be put into place (Dean, 2013, p. 366). After evaluating the site survey it is determined that a wireless local area network (WLAN) with a star topology design would work best for this office. This design gives the small office the wireless access it needs and provides wired access to the network for the shared resources, printers and wired users to connect to. I would suggest using CAT 5e wiring for the wired devices as it is cost effective and supports networking speeds up to 350 MHz (Dean, 2013, p. 102). This design also allows the office to add more users or devices easily with little impact to the network design. Security for the network will be provided by a network based packet filtering firewall, proxy server and a Wi-Fi Protected Access 2 (WPA2) passphrase. I would also suggest not broadcasting the Service Set Identifier (SSID) and to set up the router to filter the Media Access Control (MAC) addresses so that devices that have their MAC addresses registered will be allowed access to the wireless network (Dean, 2013, p. 357). I would restrict access to the proxy, file and print servers by locking them in a secure climate controlled closet. Access would be controlled by a key card that would be held by the network administrator. The packet-filtering firewall will keep out unauthorized data from entering the network and reduce the number of ports that are accessible by the users and outside threats.
The purpose of confirming instructions and requirements for business travel and accommodation is to ensure that those travelling know exactly where they need to be, what they need to bring and when they need to be there. This helps to ensure they won’t miss any trains/planes/boats etc. by allowing time for travel. It also ensures that they don’t forget something important like a passport or a document needed for the meeting which could also cause delays and embarrassment. Telling them where they are accommodated lets them know what to expect when they are staying overnight, so they can manage there expectations around room quality and service appropriately.
Firewall features are provided at the base of network virtualization platforms to bring about segmentation. It allows automated provisioning and context sharing across virtual platforms which lead to increased visibility and security across applications on virtual or physical workloads. This would have been impossible in the past as it would compromise either security or performance. Improved security through virtualization helps you gain mileage over challenges that would otherwise ruin your reputation among clients (Kotsovinos,

Network Proposal for T-Shirts R UsI was assigned to find the right hardware and software to create a reliable network for your small business. The allotted budget seems to be more than enough to provide efficient coverage for all employees. For your business’ network, you want a server-based network that will potentially support a website, connectivity for file sharing between 5-8 employees, and a printer that can quickly produce high quality images to show to customers before screenprinting. After researching these items, I think I’ve found the best solution within your current budget.Because you will be relying most heavily on the printer and server, especially in the future, I have opted to go with a wireless network to save on the installation
The additional flexibility of the screened host firewall is cause for two concerns. First, there are now two systems, the router and the application gateway, that need to be configured carefully. As noted before, packet filtering router rules can be complex to configure, difficult to test, and prone to mistakes that lead to holes through the router.
“Office Space” is a comedy movie of a man who desperately hates his job and his boss. The movie begins with Peter Gibbon’s daily life story at Initech. At work, Peter has to deal with his indifferent boss, Bill Lumbergh, who doesn’t want to listen to his employee’s feedbacks. Lumbergh seems to be an ignorant and arrogant man who dictates his employee and doesn’t want to be blamed at all. Moreover, Lumbergh asks his employee to come to work on weekend. The atmosphere in the office is getting more intense after Lumbergh announced that Initech is bringing in consultants to increase the efficiency of the company. Peter was very frustrated with everything in the office and he felt that his life even more miserable with each passing day at work. The following day, he decided to come to see a hypnotherapist in order to help him to have more positive outlook on life. Before the hypnotherapist finishes his hypnotic therapy on Peter, he has a heart attack unexpectedly and then dies. However, Peter was still under the influence of hypnosis and fails to come back to his normal state. The next day, Peter sleeps all day long – he actually supposed to come to work – and ignores all calls from his boss. On Monday, Peter comes to the office to have an interview with the consultants. Here, still under the influence of hypnosis, Peter blatantly tells everything he felt about the company. He even tells the interviewers that he only stare at his desk – looks like he is working – for hours to spend his time at work. In the end of the interview, Peter says that actually he is not lazy, but he has a problem with motivation. Peter has eight different bosses who will come by if Peter makes mistakes, so the only motivation that Peter has is not to be hassle...
Properly secure wireless systems: - To prevent data breaches it is very important to secure wireless networks. WI- Fi network security is necessary because it is very easy to hack the data and unauthorized access. Breaches can be prevented by using strong passwords, encryption methods, and strong verification.
ABSTRACT : This paper describes the basic threats to the network security and the basic issues of interest in designing a secure network. it describes the important aspects of network security. A secure network is one which is free of unauthorized entries and hackers. INTRODUCTION
A network can be based on either a peer-to-peer level or server-based, also referred to as domain-based. To distinguish the difference, a peer-to-peer network, also known as a workgroup, is a network in which a group of computers are connected together to share resources, such as files, applications, or peripherals. The computers in a peer-to-peer network are peers to one another, meaning no single computer has control over one another. There is also no central location for users to access resources, which means that each individual computer must share their files in order for other computers to have access (Muller, 2003, p.411). “In a peer-to-peer environment, access rights are governed by setting sharing permissions on individual machines.” (Cope, 2002) On the other hand, in a domain-based network, the computers connected together are either servers or clients. All of the other computers connected to the network are called client computers. The server is a dedicated machine that acts as a central location for users to share and access resources. The server controls the level of authority each user has to the shared resources. When logging on to the network, users on client machines are authenticated by the server, based on a user name and password (Lowe, 2004, p.13).
The proposed internet filter is not only a flawed concept, but an expensive one. If implemented, it will do little to nothing to prevent online crime. The cost of the filter far outweighs any benefit and the potential for abuse in the future is frightening. Viruses will still exist, phishing scams will continue, illegal downloading of movies will still exist and paedophiles will still get their child porn.
Wi-Fi (Wireless Network) or 802.11 networking is a phenomenal way of providing Internet wirelessly at a low cost. Using radio waves, a wireless network connects a PC, mobile phone or just about anything that connects to the internet wirelessly by a router. By transmitting signals at 2.4 or 5 GHz it allows the waves to transmit more data at a faster rate. Typical Wi-Fi standards are 802.11a, b, g, n, or ac and they can switch up the frequency depending on the model (Brain). Families can create their own wireless network that can be shared between family members without the use of hooking all their devices up to the modem and can also protect their home network from potential hackers with the use of a TKIP or AES encryption. Businesses can also create a “hotspot” which is an area that has wireless networks for free or at a set fee. This is extremely convenient for commuters that need internet access while they are at work, waiting on a plane, or just sitting at a coffee spot without the need for wires(Cox).
Local Area Networks also called LANs have been a major player in industrialization of computers. In the past 20 or so years the worlds industry has be invaded with new computer technology. It has made such an impact on the way we do business that it has become essential with an ever-growing need for improvement. LANs give an employer the ability to share information between computers with a simple relatively inexpensive system of network cards and software. It also lets the user or users share hardware such as Printers and scanners. The speed of access between the computers is lighting fast because the data has a short distance to cover. In most cases a LAN only occupies one or a group of buildings located next to each other. For larger area need there are several other types of networks such as the Internet.
In addressing the problem, the proposed research will use the case study method to examine the plan, design, and implementation of WLAN technologies at Berean. At present, the non-wireless local area network (LAN) technologies employed by Berean include 10/100BaseT Ethernet at each desktop. Ethernet ports at the desktop are switch connected to an Asynchronous Transfer Mode (ATM) T1 backbone. Berean¡¦s one remote facility connects to the network using switched Frame Relay services along with Internet Virtual Private Network (VPN) connections.
