I have decided to pursue the career of a network system administrator or IT professional. Over the last ten years or so computers have become fundamental parts of everyday life‚ used for a variety of reasons at home‚ in the workplace‚ and at schools. Of course every computer user runs into obstacles from time to time‚ whether it is the blue screen of death‚ the forgotten password‚ or the loss of important data. The explosive use of computers has created a high demand for specialists to provide advice

There is nothing more important in any business than securing your network topology from hardware‚ design and software. This plan is called network hardening and this plan needs to be incredibly detailed with how the network will be secured in each area. The first step to the network hardening plan resides in how you will build the network and then from there how you will secure each section of the network. This paper will discuss access control measures‚ encryption‚ PKI‚ certificates‚ OS hardening

Once those have been identified‚ Team “C” will identify the data security issues and concerns present at each Riordan plant. Finally‚ Team “C” will address web security issues and concerns present

Network security concepts Network security starts with authenticating‚ commonly with a username and a password. Since this requires just one detail authenticating the user name —i.e. the password— this is sometimes termed one-factor authentication. With two-factor authentication‚ something the user ’has’ is also used (e.g. a security token or ’dongle’‚ an ATM card‚ or a mobile phone); and with three-factor authentication‚ something the user ’is’ is also used (e.g. a fingerprint or retinal scan)

Introduction Network architecture is a combination of topology and protocols. In this paper‚ I will discuss topology‚ which is the defined as the shape of a network or how a network is laid out. Topology also consists of how the different components or nodes of a network are connected and how they communicate with each other. Topologies are either logical or physical. In addition‚ in the sections of this paper‚ I will compare and contrast some different conventional architecture and what types of

Carrier Sense Multiple Access with Collision Avoidance. However‚ simple CSMA is susceptible to the hidden node problem‚ especially in so called ad hoc networks where a node may communicate directly with every other node in range or using intermediate nodes as relays otherwise. Hidden nodes cause costly packet collisions and thus significantly affect network performance. In order to combat the hidden node problem‚ a mechanism known as Request to Send/Clear to Send (RTS/CTS) handshake is often used. RTS/CTS

Wireless Network A wireless network‚ as its name would suggest‚ is a network of computers and computer peripherals that are connected to each other without wires. This enables ease of communication‚ especially for mobile computing platforms. Further‚ there are a number of other advantages to a wireless network that make them increasingly common in both the workplace and at home. Nearly all wireless networks in the world work on a standard set up by the Institute of Electrical and Electronics

Network Hardening Unit 8 Assignment 1 It is very important to go through the process of hardening. Hardening is where you change the hardware and software configurations to make computers and devices as secure as possible. I picked the network layout 1-the workgroup . First with the workstations and laptops you need to shut down the unneeded services or programs or even uninstall them. I would also have some good anti-virus software on the workstations. You also need a hardened image for
