Network Management and Optimization Proposal This is a proposal for network management and optimization. The network has grown rapidly, and the company has not completed proper documentation and policies. This proposal includes required documentation; network monitoring, event logging, and maps; data backup; and network optimization. Documentation In order to maintain, troubleshoot, and prevent network outages, network administrators need to refer to documentation. Required documentation includes
Man-in-the-middle attacks, and Network manipulation with spoofed management frames, Threats in the physical layer. Rogue base stations It is defined as an attacker, which copies a legitimate base station. It allows hackers to confuse subscribers. WiMAX uses time division multiple access, thus the rogue base station must transfer with a stronger power at the same time the legitimate station transfers. The authentication protocols (EAP Protocol) used in WiMAX help relieve this threat. (EAP Protocol forces mutual authentication
Introduction Short for Simple Network Management Protocol, a set of protocols for managing complex networks. The first versions of SNMP were developed in the early 80s. SNMP works by sending messages, called protocol data units (PDUs), to different parts of a network. SNMP-compliant devices, called agents, store data about themselves in Management Information Bases (MIBs) and return this data to the SNMP requesters. Each SNMP element manages specific objects with each object having specific
Vulnerabilities 3. GNS3 Setup A network topology in GNS3 (Graphical Network Simulator) is used in conjunction with Backtrack 5 to demonstrate the exploit tools of Cisco. The topology consists of three routers connected to one switch which is connected to a cloud. The cloud will act as Backtrack. The network address is 192.168.6.0/24. Each router is configured with separate IP addresses in the network. Backtrack is connected to the cloud on the same Vmnet custom network. (See Figure 3-1 below). Figure
Organizations which rely on network infrastructure for their business operation must utilize security technology to protect the network from harmful actions of automated attacks as well as malicious human activity. It is also important to enact policies and guidelines for the employees of the organization, which in many regards can be the weakest link in the chain of security. According to a survey by The Ponemon Institute (2012), “78 percent of respondents said their organizations have experienced
Corporate Networks in organisations can be complex structures that “requires a great deal of attention” (Clemm 2007). Even small companies can have quite complex networks that are a considerable investment to the business. The notion that corporate network management is a cost to a business rather than a continual beneficial investment is a naive assumption that requires further investigation to the benefits that network management brings. Clemm (Clemm 2007) states in his text that the ultimate goal

assortment of devices on a network depending on the size. These devices need an effective method of communication between themselves in order to relay the information to the correct destination. The communication protocols are a set of standards that tell different hardware and software how to transfer data elements between them. When working with the OSI model, the protocols will govern communication between entities on the same reference model layer. Network protocols include mechanisms for devices
Intrusion prevention helps in identifying attacks/threats over the network and responds to the threats without any delay. Intrusion prevention system (IPS) works similar to Intrusion detection system (IDS), where both monitor traffic over the network. However, IPS is more active in nature as it takes immediate action on the attack that has occurred. The action taken by IPS is based on the rules that have been set by the network administrator. Intrusion prevention system performance metrics are measured
Underwater wireless sensor networks are significantly different from terrestrial sensor networks in which sound is mainly used as the communication medium. This paper reviews the main challenges caused by the underwater environment for the development of efficient under water sensor networking solutions and introduces several novel medium access control (MAC) protocols with power control to increase efficiency and save on energy. I. Introduce Underwater wireless sensor networks (UWSN) has received growing
In order to determine the flow and types of packets on the network, a packets sniffer program ‘Wireshark’ was used to capture the packets. Wireshark was used to capture 30 minutes of network activity in two different intervals, morning and afternoon. The partial output from the Wireshark capture, from both sessions is shown in figure 4.4; from analysis of the packet sniffer program it can be deduced that the network traffic usage is mainly TCP connections, such as web browsing, file transfer and
TCP/IP protocols and the Internet are different, their evolution are most definitely parallel. This section will discuss some of the history. Prior to the 1960s, what little computer communication existed comprised simple text and binary data, carried by the most common telecommunications network technology of the day; namely, circuit switching, the technology of the telephone networks for nearly a hundred years. Because most data traffic transmissions occur during a very short period of time, circuit

CHAPTER 3 Routing Protocols The nodes in Ad hoc network are free to move in random fashion within the network region due to which the network topology changes randomly or dynamically. This random movement of nodes plays an important role on the performance of routing protocols[30,31]. Considering the node mobility feature it is essential to choose a suitable routing protocol based on the network environment. Because the nodes are mobile in nature and are moving randomly anywhere so its an important
Transmission control protocol while IP stands for Internet protocol. They are merged together to form the Internet protocol suit which is a model for networking which consists of communication protocols which are used for internet and other similar networks. This protocol suite was designed and developed by the Department of Defense (DoD). It was developed in order to connect different networks which were designed by different vendors. By use of TCP/IP, several computers on small network in a department
so vehicles have sufficient amount of energy and power including both processing and storage; so the battery power and storage is not an issue in VANET. Frequent network disconnection-In VANET, vehicles move very frequently on the roads, in the network due to this the link connectivity in VANET also change frequently. The chances of network disconnection are high when the density of vehicle is low. Mobility modeling and prediction-Due to high dynamic topology, mobility modeling and prediction play
is a network model which enables the communication across the Internet. The most fundamental protocol on which the Internet is built. This is made up of the 2 common networking protocols, TCP, for Transmission Control Protocol, and IP, for Internet Protocol. TCP maintains and handles packet flow linking the systems and IP protocol has the ability to handle the routing of packets. However The TCP/IP stack consists of 5 layers first being application layer, the transport layer, then the network layer
TCP/IP Overview When designing networked applications one key protocol stands out as the foundation for making it possible. That protocol is TCP/IP. There are many protocols out there that allow two applications to communicate. What makes TCP/IP a nice protocol is that it allows applications on two physically separate computers to talk. What makes TCP/IP great is that it can do with two computers across a room or across the world. In this paper I will show you how TCP/IP allows a wide array of computer
Network Security is the protection of the computer’s network though out the entire infrastructure. It can protect very important information and computer files to help prevent theft, spyware, malware, viruses, and more. Depending on if you have a public or private network, can determine what type of security settings you need for your network. All people are different on what they want to have secured or not, but most people do not know how to prevent people or things from getting in their network
