Security Design of Logistics Service †Free Samples to Students

Question: Discuss about the Security Design of Logistics Service. Answer: Introduction The report is prepared for the Acme for converting the IPv4 environment of the organization into IPv6. The current network of the organization is required to be upgraded with the implementation of the IPv6 addressing schemes for connecting with the network configured with IPv4 address. The IPv4 protocols are compared for the development of the network and the advantage that the organization can gain with the implementation of the IPv6 address in the network is also discussed in the report. The network design is created and configured in packet tracer for building a prototype of the network and testing the functionality. The VTPv3 protocol is used for the accommodation of the changes in the current network and initializing the initial function and it allows the routers to update the other device connected in the network. With the implementation of the protocol the risk of changes in the network can be eliminated and the performance of the network can be improved. Different VLANs are created for the different departments for the segmentation of the LAN (Genge, Haller Kiss, 2017). The VLAN secure the transmission of the data packets in the network and increasing the flexibility of the network. The spanning tree protocol is used for deployment of a logical loop in the network and provide backup links for enabling fault tolerance in the network. The Ethernet channels are configured with trunk protocol for enabling the VTP domain and enabling the other domain to communicate using the secure channel (Tree, 2014). The routers are configured using dual stacking i.e. with IPv4 and IPv6 addressing such that i t can communicate with the IPv4 and the IPv6 network efficiently. DHCP configuration is done on the router for automatically allocating the IP address to the device connected in the network. Intervaln routing is configured in the network using the ip routing command and enabling the created VLAN to communicate with each other (Loo, Mauri Ortiz, 2016). HSRP is used for the configuration of the network and increase the availability by enabling the routers to appear as a single interface. System testing and verification Strategy A prototype of the network is created and is tested before implementation in the real life. For the deployment of the network solution for Acme the similar network is configured in cisco packet tracer and the switch is configured with spanning tree and the network is monitored for checking the availability of the network devices. A machine is used for generating request and create traffic in the network. The devices used for the network connection are pinged with each other for testing the connection between the devices. The VLANs created are also pinged for testing the connectivity of the VLAN and the configuration of the intervlan routing in the network. The router is also configured with IP helper for allowing the central router configured with DHCP to provide IP address to the devices connected in the network. The topology of the IPv6 network is created and feasibility of the solution is analyzed for the development of the network. The testing is performed and simulation is done on packet tracer for testing the network of the organization. The main issues identified in the network is the management of the devices and configuring the devices with the IPv4 and IPv6 addressing schemes. For troubleshooting the network the devices are pinged and the connectivity between the devices are verified. The interface of the created VLANS are also pinged for checking the connection of the VLANs and if there is a failure in the ping the host device is checked for identification of the problem in the network solution. The device connected in the VLAN 99 is required to be able to ping with the device connected in the VLAN 120. Configuration the network with HSRP was also an issue because a virtual MAC Address is required to be created for enabling the devices connected in the network to connect with the interface of the router. The load of the network is shared using multiple HSRP and an active route is created for the router and assigned priority for improvement of the normal operation of the network. Implementation and functionality For the implementation of the network solution the current network infrastructure and the requirement of the company is analyzed. The proposed network is configured with IPv6 address and the protocols used for configuring the network are analyzed for the configuration of the routers. The current network of the organization is developed in IPv4 and it is required to be converted using the IPv6 protocol for increasing the efficiency of the network (Eskandarpour et al., 2015). The version of the OS of the routers and the switch are required to be upgraded for allowing the configuration of the IPv6 address in the devices. For the creating of an effective network solution the location for the installation of the devices in the network is required to be analyzed and the scope of growth of the network and the number of branches required to be covered is also required to be listed. Remote access of the network can be enabled for increasing the functionality of the network and allowing the re mote users to connect with the core components of the network (Khan, Pathan Alrajeh, 2016). The router can be configured with VPP and the servers are required to be configured for increasing the security of the network. Forwarding Logical Addressing Routing and Positioning of the network layer Forwarding- the switch and the router is configured with forwarding and the packets received by the device is required to be forwarded to the destination address for increasing the efficiency of the network. Logical Addressing- It is used for definition of the network rules and relate the structure with the IP address. The nodes in the network should have an IP address and rules is created for partitioning the network. Routing- the routers are configured with routing protocol for the calculation of the next hop address of the router and establish the connection between the sender and the receiver in the network. IP route is used for establishment of the data connection between the different devices connected in the network. Positioning of the network layer- The data link and the transport layer of the network is positioned for communicating in the network. The network layer cooperates with the data link layer for sending and receiving the data packets in the network. Conclusions From the above report it can be concluded that for changing the current network framework of Acme and deployment of the IPv6 addressing different routing protocols are used. An addressing plan is required to be created for assigning IPv6 address to the network devices. The devices are also upgraded with the latest software version for allowing the reconfiguration with the new technology and reducing the cost of the network up gradation. The network is required to be configured with dual stack for communicating with the old device configured with IPv4 address. Different VLANs are created for different branches and intervlan routing is used for connecting with the vlans and increase the efficiency and security of the network. The three routers connected in the network are configured with HSRP such a virtual router is created and availability of the network is increased.
