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
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
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
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
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
Halamka needs to implement to truly improve CareGroup’s change management process in addition to the actions already listed in lessons #5 and #7. (Hint: the actions listed in those two lessons are NOT sufficient to achieve good change management – other things discussed in the assigned readings and in COBIT are also required). The events that unfolded at CareGroup in late 2002 highlighted the importance of proper monitoring and change management procedures—as well as the value of having a completely independent
P1 Describe Network Technology Network technologies are needed to create a network. They include network: Operating systems (OS) System working frameworks are the product that keep running on a server and permits the server to control the capacities in a system, for example, oversee information, clients, bunches, security, applications, and other systems administration capacities. For Example: Windows Linux OS X (SnowLeopard) Protocols A convention permits PCs
wired media is media used to transport information through a network that involves the use of physical pathways i.e. wire. The most common types of wired transmission media include telephone cables and coaxial cables. With regards to computer networks, a wired home network involves connecting the computer or other related devices to a Super Hub with an Ethernet cable (“Wired or Wireless”, n.d.). However, the use of wired networks in computer systems has lessened significantly because of the introduction

the advantages of subnet? Answer: A subnet is a logical grouping of network devices. which mention which hosts a part of a sub network number are come with the subnet is divided into their respective networks virtually defined sections allows the administrator to gain a lot of network subnets. When there as any organization network divided i nto subnets allows it to be connected to the Internet with a single shared network address. Subnets outside an organization can obtain multiple Internet Correspondence
stands for Virtual Private Network. VPN is a data network connection that makes use of the public telecommunication infrastructure but maintains privacy through the use of a tunneling protocol and security procedures. It operates much like a Wide Area Network (WAN). Most companies actually leased lines, but in either case both solutions are very expensive. As the Internet became more widely available people started creating VPN solutions that took advantage of the cheap network access. The idea was
What is FCAPS? FCAPS is a telecommunication management network and network management software (NMS). FCAPS is an acronym that stands for its five network management categories. F stands for Fault Management, C stands for Configuration Management, A stands for Accounting, P stands Performance management, and S stands for Security Management. When it comes to Networking and providing internet as a service, availability and performance are required. With FCAPS model of NMS, this ensures that the uptime

computer networking and telecommunications, Multi Protocol Label Switching (MPLS) is a data-carrying mechanism that belongs to the family of packet-switched networks. When it comes to getting network traffic from point A to point B, no single way suits every application. Voice and video applications require minimum delay variation, while mission-critical applications require hard guarantees-of-service and rerouting. So far, only circuit-switched networks have provided the differentiated services and
Network Design Network Design is very important when it comes to implementing a connection between a computer and a server. According to Network world Websites, Network is defined as a “connected collection or devices and end systems, such as computers and servers, that can communicate with each other”(McQuerry). Network carry data in many types of environment, such as homes, small businesses, and large enterprises. Network Locations Is one of the major factors. There are different types and locations
Introduction In this modernize world, internet and network are very vital and important not only for individuals but also for companies, organization, institution, etc. Because of this, it is very important to make use of as many network devices available. We need to study more or at least to have a glimpse of information about the networking devices before we choose or start using it. There are many networking device out there that able for us to study but the chosen device for this report are hub
LANs: Local Area Networks Local Area Networks also called LANs have been a major player in industrialization of computers. In the past 20 or so years the worlds industry has be invaded with new computer technology. It has made such an impact on the way we do business that it has become essential with an ever-growing need for improvement. LANs give an employer the ability to share information between computers with a simple relatively inexpensive system of network cards and software. It also lets
Networking Protocols for Different Applications How does one get two computers to interact with each other? By using a network. A network allows two or more computers to exchange data over a medium. Rules are needed so that the computers know how to communicate. These rules for the language computers use to transmit information are called protocols. As with the many different languages people around the world use to communicate, there are many different protocols. Some of these protocols include
