...5.3 Design Phase IP address? Software hardware use? Design phase is the most important and analytical phase. The network design is developed based on the technical and business requirements obtained from the planning phases. The network design specification is a comprehensive detailed design that meets current business and technical requirements. It provides high availability, reliability, security, scalability, and performance. The design includes physical, logical network diagrams and an equipment list. The project plan is updated with more specific and detailed information for implementation. 5.3.1 Network Topology Design After everything have been detailed in the plan phase, I proceed to design them according to the paperwork or project plan. During this stage, I have design the topology for the new office which meet the requirement and criteria stated. Both physical and logical diagram are being created in this phase. The application or software that I used to design the topology is Creately.com and Packet Tracer 7.0. Creately.com is an online application that provides user to draw UML diagram, flowchart, network diagram and many more. The reason that I used this online application is it is free and easy to use instead of I need to draw by myself for the physical topology. Figure 4 - Creately Homepage GUI Figure 5 - Cisco...

...Phase 1: Identifying Requirements, Putting the Network Together Scenario NuggetLabs Industries is growing significantly. Due to space limitations, five employees currently share single cubicles…at the same time. While this is great for team building, these space limitations are now impacting business productivity. NuggetLabs has now leased an additional office building roughly 20Km from their headquarters location. While this office will eventually connect to the HQ office, it will initially be set up independently. NuggetLabs Industries has heard rumors of your ninja-like network consultation skills and has agreed to pay you an excessive amount of money to design and build their network infrastructure. Gathering Information To help guide this initial configuration, you‘ve assembled a list of requirements based on various meetings with management. * The new office will initially house 75 employees, each with their own Cisco IP Phone and PC. This office may eventually scale to 200 employees over 5 years. * The Windows admins are planning to install a new pair of redundant servers at the new office. They plan to manage all the IP addresses for DHCP on these servers and are waiting for you to tell them what IP address range they should use. * Windows admins: Jeff Service - (602) 555-1293, Mike Pack (480) 555-9382. * The new office is a two story building with the Main Distribution Frame (MDF) in the northwest corner of the first floor.

...Brittany Martin IT245-1303A-03 Introduction to Network Management Phase 3 DB 8-1-2013 This week in phase 3 we are on the subject of how OSI (Open Systems Interconnection) model and TCP/IP (Transmission Control Protocol/Internet Protocol) are similar and how they are different. There are 7 layers in the OSI model and there are only 4 layers in TCP/IP. The 7 layers in OSI are application, presentation, session, transport, network, data link, and physical with application being the highest and physical being the lowest of the model (Harney, n.d.). The 4 layers of TCP/IP are application, transport, internet, and subnet (Harney, n.d.). In the OSI model the application layer simply handles a lot of software protocols such as DNS, and HTTP. The presentation layer transfers data from one end to the other. The session layer handles connection between two devices. The transport layer makes sure information is formatted in the proper way. The network layer sends information over to the proper web address. The data link layer makes sure data is small enough to be sent across the network to arrive in the correct place. The physical layer deals with all hardware including NIC’s, hubs, and Ethernet cabling. The TCP/IP only has 4 layers because one or more layers of the OSI models is composed in the TCP/IP model (OSI Model vs. TCP/IP Model, n.d.). In the application layer it deals with the user and how data is handled with that user. The transport layer deals with communication...

...Unit 9 Assignment 2 Phases of a computer attack Phase 1 - Reconnaissance Phase 2 - Scanning Phase 3 - Gaining Access Phase 4 - Maintaining access Phase 5 - Covering Tracks Phase 1: Passive and Active Reconnaissance Passive reconnaissance: This is the process of scouting out a company or individuals knowledge and processes, such as finding out when employees come in to work and leave work. It can also be the result of researching the company through the internet via search engines. Active Reconnaissance: This is the process of actually scanning the network to find out IP address and services that the network provides. This process will help the hacker determine what vulnerabilities are on the network as well as other important information such as what operating systems the network is using. This is a more intrusive part of reconnaissance than the passive way and has a much higher risk of being detected. Phase 2: Scanning This is the process of using the information discovered in the reconnaissance stage and using programs such as port scanners, network mappers, and sweepers. This can result in getting information such as the user accounts, IP addresses and computer names. Phase 3: Gaining Access This is the phase where you are taking the information gathered from the reconnaissance and scanning phase, the information gathered is used to exploit vulnerabilities in the network to gain access. There are several ways to do this such...

...VPN Concepts A virtual private network (VPN) is used to transport data from a private network to another private network over a public network, such as the Internet, using encryption to keep the data confidential. In other words, a VPN is an encrypted connection between private networks over a public network, most often the Internet. VPNs provide the following services: Confidentiality: VPNs prevent anyone in the middle of the Internet from being able to read the data. The Internet is inherently insecure as data typically crosses networks and devices under different administrative controls. Even if someone is able to intercept data at some point in the network they won’t be able to interpret it due to encryption. Integrity: VPNs ensure that data was not modified in any way as it traversed the re Internet. Authentication: VPNs use authentication to verify that the device at the other end of VPN is a legitimate device and not an attacker impersonating a legitimate device. Cost savings - VPNs enable organizations to use the global Internet to connect remote offices and remote users to the main corporate site, thus eliminating expensive, dedicated WAN links and modem banks. Security - VPNs provide the highest level of security by using advanced encryption and advanced authentication protocols that protect data from unauthorized access. Scalability - Because VPNs use the Internet infrastructure within ISPs and devices, it is easy to add new users. Corporations...

... TABLE OF CONTENTS Introduction to tcp/ip tcp ip operaction ,s of tcp/ip layers in tcp/ip model tcp/ip protocols References INTRODUCTION TCP/IP------------ The Transmission Control Protocol (TCP) is one of the core protocols of the Internet protocol suite (IP), and is so common that the entire suite is often called TCP/IP. TCP provides reliable, ordered, error-checked delivery of a stream of octets between programs running on computers connected to a local area network, intranet or the public Internet. It resides at the transport layer. Web browsers use TCP when they connect to servers on the World Wide Web, and it is used to deliver email and transfer files from one location to another. HTTP, HTTPS, SMTP, POP3, IMAP, SSH, FTP, Telnet and a variety of other protocols are typically encapsulated in TCP. Applications that do not require the reliability of a TCP connection may instead use the connectionless User Datagram Protocol (UDP), which emphasizes low-overhead operation and reduced latency rather than error checking and delivery validation. TCP---------- The Transmission Control Protocol (TCP) is one of the core protocols of the Internet protocol suite. TCP provides reliable, in-order delivery of a stream of bytes, making it suitable for applications like file transfer and e-mail. It is so important in the Internet protocol suite that sometimes the entire suite is referred to as "the TCP/IP protocol suite." TCP is the transport protocol that...
