Task 2 Problem is network Security .In the company network, I designed the external network and internal network security, In Internal we will use the cisco Layer 3 switch can be divided into different vlan, the departments to separate vlan. For example, accounting department vlan can only account department staff to access the accounting department server files other

VNC is stands for a Virtual Network Computing which is an open source platform for accessing desktop on remote machines with the help of LAN over a WAN or Internet connection. In this project discuss various methods of developing or building a virtual network with provides a good security to each one of them. VNC is platform independent so we can use any operating system such as UNIX, Windows, MAC OS x etc. It will also cover the open connection and tunneled connection of SSH (Secure Shell). In my project, I will apply technique to build a secure virtual network. In this present era there are many multinational company in the market company users are able to share their resources and applications without any kind of high level on software and hardware resources. Mobility is important in this fast peace world therefore the

In the Future Corporation LAN, I have decided to some Virtual Area LAN Network (VLAN) for better performance, easier administration, less cost, and better security. There will be two VLANs for each department, total will be 26 VLANs. The first VLAN in each department will be only for the employees' department, and the second VLAN will be for the guests. I have decided to use static VLANs, so every port will be configured to be belong to a VLAN. I have selected static VLANs instead

VLANs or Virtual Local Area Networks are logical local area networks that extend beyond the traditional LAN architecture. Because a VLAN is a logical entity, creating and configuring a VLAN is done completely in software. The advantages to using this type of LAN include but are not limited to the ability to conserve the network resources, to bridge geographical drawbacks, and to better manage the movement of personnel and equipment. To understand the need for VLANs you must first understand the Local Area Network (LAN). The definition of a LAN started as a group of computers that were connected in the same area, but today’s LAN is defined as a single broadcast domain. This is explained easily by looking at a large organization where each department would be on a separate LAN found behind a router or switch. With today’s expanding networks it has become important for these

A VLAN or virtual local area network connects departments, which are not connected physically. VLANs will be implemented while using the Trunking VLAN Protocol. To ensure that all departments are grouped together, they will use network assigned VLANs. The VLAN information is stored on the VTP server so that it is centrally located for easy maintenance. By grouping the departments together, the sales departments will all be connected with each other along with the administrative departments connected with each other. This gives the administrator an easier way to manage the data flow and increase security when needed. The network will also implement the Spanning Tree Protocol

With this process, the host is checked against the corporate policy to determine if the host is compliant or not. With this check it determines what level of network access that the host will be given. Cisco network access control is also a posture based access control. With this access control comes two solutions: 802.1x and Clean Access; 802.1x solution will make use of a RADIUS server which will be used for authentication. Clean Access authenticates users through a web browser, which also checks to see if the user is compliant with the enterprise

In the past, companies were hampered by the cost, performance, and security issues that are associated with local area networks or LANs. LANs must be connected physically to switches which means that each LAN must have its own switch (prtl.uhcl.edu, 2016, para. 13). The virtualized version of the LANs, virtual local area networks (VLANs), allows users to invest in only one switch (prtl.uhcl.edu, 2016, para. 13). The VLAN is used in the virtual data center environment to separate a single LAN into more than one network while being physically connected to one switch. One advantage of VLANs is that network administrators can now sort devices by whatever criteria they require without physical location being an issue. Different VLANs can be set for different groups or departments within the same LAN. Performance is improved because, when the LAN is broken up into VLANs, it is not receiving broadcasts from all of the devices (certbros.com, 2015, para. 4). Cost is decreased because separate switches are not required for VLANs. A security benefit is provided because VLANs can be configured to accommodate the different security levels needed, and the administrator can choose whether or not to allow the VLANs to communicate with each other (certbros.com, 2015, para. 6).

This model protects from threats and issues, Identifies loop holes in vulnerabilities, unauthorized admittance and serious charges. This paper discusses various ways of network management. Precautions to be followed before any disaster takes place and a conclusion stating the result of the paper is presented.

Membership in VLAN can be defined based on ports that belong to VLAN. For example, in a bridge with four ports, ports 1,2,4 belong to VLAN 1 and port 3 belongs to VLAN 2.”

The case studies are based on VXLAN basic idea and its benefits. Originally VXLAN had been invented for the big benefit where in VLAN, user cannot have more than thousand VLANs’ in network per device but now, we can get 16 million VXLAN configuration possible on single virtual switch environment using combined approach of Cisco and VMware products.

Network Addressing and Architecture: Effective management of potential threats are dependent upon network architecture. If network architecture security is not managed properly, then it can cause to raise the specific risks like loss of data, loss of data integrity and denial of service. Network architecture is a framework designed to meet its operational principles and requirements. Now a days, new types of devices are being introduced in organization to address the business needs, which may

We use Networks for file sharing, printer or peripheral sharing, Internet telephone service, multi-player games and many more. But, Normal networks are more complex. Configuring network devices requires a lot of effort and generally has to be done manually by devoted admin. If a network file server promotes a fault, then many users may not be able to run application programs and get entry to shared data [2]. Users can lose data because of a fault on the network. It is hard to make the system secure from hackers, fresher or industrial spying. The larger the network, the more difficult it is to manage.

A VLAN stands for virtual local area network, which is a group of host computers/ networks/ single-user PCs or workstations (i.e. clients) that have a common set of requirements and are attached to the same domain (the server). The server provides clients with a set of shared services and helps clients to share access to the same database as well as to communicate with oen another. With their networked computers, Company LTET can communicate between its manufacturing plants in China and its assembly and distribution plants, as well as HQs and offices in the US.

Implementation of VLAN and VPN Access: the VLAN-VPN allows packet with a VLAN tag, the device will label the packet with the default VLAN tag of the receiving port and add the source MAC location to the MAC location table of the default VLAN. If the packet transports a VLAN tag, the packet turns into a double labeled packet. Then the packet turns into a bundle conveying the default VLAN tag of the port. [2]

MPLS works by prefixing packets with an MPLS header, containing one or more "labels". This is called a label stack. Each label stack entry contains four fields:
