IntroductionThis is a scenario based project for a small company as described here. ALS Pty Ltd is a SME(Small to Medium Enterprise) based in Sydney. The company is a new start-up specializes indesigning and manufacturing widgets. The company has 60 employees at their new Head Officein Sydney. The company decided to setup a LAN infrastructure environment with Centralizedauthentication and resources (object) management. They organization structure is based ondifferent departments named Sales, HR, Operation, Finance and Marketing. This is completed onthe basis of the network diagram, IP addressing, active directory installation, DNS forward andreverse look up, OU creation and other stuff mentioned in the file. All the tasks have beenrecorded and presented in the form of screenshot also. Design of Network DiagramThis is a logical network diagram which displays the flow of data through various devices. Router is kept at the top as it routes the whole traffic to the internal and external environment. This is the reason that router has internal IP address as well as external IP address. It uses its internal IP to communicate with the switches and routers inside the infra and external IP to communicate with the devices kept outside the infra. Router connects with the switches inside which further provides or allocates IP to the peripheral machines for communication. Peripheral devices include computers, laptops, printers, IP phones, etc. Switch connects the devices kept in same network. For connecting two different networks, routers are used. To ease the management of IPs for different departments, concept of VLAN is used so that it avoidsthe risk of IP conflict.

Below diagram is a flowchart for the devices that are integral to the proper functioning of the network in any infra. These include router, switch, firewall and peripheral devices. Router is kept at the top as it routes the whole traffic to the internal and external environment. This is the reason that router has internalIP address as well as external IP address. It uses its internal IP to communicate with the switches and routers inside the infra and external IP to communicate with the devices kept outside the infra. Router connects with the switches inside which further provides or allocates IP to the peripheral machines for communication. Peripheral devices include computers, laptops, printers, IP phones, etc. Switch connects the devices kept in same network. Firewall is the security device that filters the data that is being traveled inside the premises. There are different firewall rules that are applied in the devices that restricts and allows only certain IP addresses to be there. Restricted ones are not allowed to enter the infra and are dropped before entering. This is the reason that ports are blocked so that not all data is transferred from outside world to the infra. This makes the whole environment secure.
