Once the network has been fixed, all of the computers on the network will be able to transfer and communicate information back and forth. That’s why a communication protocol is very important. Traffic analysis is defined as the process of gathering information from the features of communication traffic other than its contents, such as timing and size. Traffic analysis can be utilized on any type of network. When using traffic analysis, this process reveals the amount, type, origin and destination of the traffic flow on a network.
2. Workstation domain • The Workstation Domain is where most users connect to the IT Infrastructure. Desktop computers, laptops, or any device that connects to a network is considered a workstation .A logon ID and password is needed for access. Requires tight security and access controls. 3.
The __________________ tool provides a central access point for all of the network controls and connections on a computer running Windows 7. Network and Sharing Center 3. A device that connects one network to another is called a __________________. router 4. The most common method for illustrating the operations of a networking stack is the __________________, which consists of __________________ layers.
The network layer then uses its protocol (IP) and translates that www.yahoo.com into an IP address. The network layer is also in charge for determining the best route through the network in order to get to the IP address destination. The data link layer is, unlike the other two which are virtual, a physical address with is permanently encoded to a device through its network card. The data link layer is a unique identifier to each computer in a network. Thus a MAC address is the only address that will always remain the same, transport and data layer address can change depending on the network.
1. What is the Internet? The Internet is a globally interconnected network of computers that, operating via several specific protocols, serves as a worldwide information system and provides the technological infrastructure on which countless applications are run (Leiner et al., 2012; Woods, 2013a). At the hub of every network is a server, with the Internet essentially being formed through the connection of multiple servers, encompassing all connected computers and creating a larger ‘inter-network’ (Woods, 2013b). Each device on the network has a unique numerical address and the Internet uses the DNS (Domain Name System) to allocate each a corresponding human-readable address (Woods, 2013a).
This database lists user accounts and resource security information for the computer on which the database resides. All information about users and a group is stored in the local security database. Each computer user can share resources such as printers and folders with others by setting access permissions for groups or individual users. In order for a user to gain access to any computer in the workgroup, he or she must have a user account on every computer. Furthermore, in order to maintain complete access to all computers on the network, if you make changes to a user account, you must update each computer in the workgroup with the changed information.
My love of computers sparked my endeavor into this field. My education background includes an associates degree in networking, and a bachelors degree in computer administration. My job entails installing, configuring, and maintaining local area network (LAN), wide area network (WAN), and Internet system or a segment of a network system. I also supervise other network support, coordinate, and implement network security measures. (reference) What is needed I as a network and computer systems administrator must know the ends and outs of any computer system, as I interact with them on a daily basis.
It’s imperative that we not only protect against these types of activities on the network, but that we also conduct them ourselves. Ping sweeps are what they sound like. They’re a regular ping that almost anyone in the IT field uses as a basic troubleshooting step but, they are conducted across an entire range of addresses. Whereas a normal administrator would only ping one or two destinations, a malicious user may conduct a ping sweep to find every endpoint on a network that they are allowed a connection to. Most utilities that perform this operation can also perform a DNS lookup on all the IP addresses as well to produce the end points names.
