File Transfer Protocol (FTP) is an application layer protocol, which has the primary function of transferring data files between computers (Clark 2003). The protocol specification was originally developed in the early 1970s, and was published as RFC 114 in April 1971, by Abhay Bhushan. This occurred even before the Internet Protocol Suite – commonly known as TCP/IP or Transmission Control Protocol (TCP) and the Internet Protocol (IP) – was even established (Kozierok 2005). The protocol specification
Cyberspace in William Gibson's Neuromancer As described by William Gibson in his science fiction novel Neuromancer, cyberspace was a "Consensual hallucination that felt and looked like a physical space but actuallly was a computer-generated construct representing abstract data." Years later, mankind has realized that Gibson's vision is very close to reality. The term cyberspace was frequently used to explain or describe the process in which two computers connect with each other through various

As a classified employee, the teacher has access to files which contain students’ personal information, including their full names, home addresses, parents’ names and addresses, as well as the students’ grades for courses taken at the high school level and other personal information. Unfortunately, some of these confidential files were shared via a file sharing server and found their way into the hands of a reporter at the Las Vegas Sun. The reporter
Structure of the Internet was developed through last 30 years of existence of the Internet. The Internet is a heterogeneous worldwide network consisting of a large number of host computers and local area networks. The Internet uses the TCP/IP suite of protocols. This allows the integration of a large number of different computers into one single network with highly efficient communication between them. This way, the user can access information on all kinds of host computers from a desktop PC, Macintosh
other computers around the world. Telnet is a plain ASCII terminal emulation protocol that is still used to access a variety of information sources, most notably libraries and local BBS's. This report will trace the history and usage of this still popular and widely used protocol and explain where and how it still manages to fit in today. HISTORY AND FUTURE OF TELNET "Telnet" is the accepted name of the Internet protocol and the command name on UNIX systems for a type of terminal emulation program
The Internet is possibly one of the most innovative and useful inventions of our time. The Internet can be defined as a worldwide system of connected computer networks that are linked to countless amounts of devices through out the world. Todays Internet allows us to complete just about any task you can throw at it, anything from shopping, paying taxes, keeping in touch with friends, and even starting your vehicle. The rate at which the Internet today is progressing is truly remarkable; there
plays an important role as a security blanket for management. Last, a firewall can act as your corporate ambassador to the Internet. Many corporations use their firewall systems to store public information about corporate products and services, files to download, bug-fixes, and so forth. Several of these systems (such as uunet.uu.net, whitehouse.gov, gatekeeper.dec.com) have become important parts of the Internet service structure and reflect well on their organizational sponsors.

Introduction The proposal will talk four Internet services that are essential to enable efficient and secure communication with customers and internal staff. And for each Internet service I proposed, describe its usage and explain why the service is appropriate. Four Internet services Firstly, I set up a “Facebook Page” for Starbucks Coffee Company. In the page, it has the latest news in which the latest Starbucks Coffee information. For example, when the new coffee product release? How to drink
the left column. Make sure 'Enable Account' is selected. Enable 'Max Number of Users' set it at a number other than zero. 1 for a personal account and more that one for a group account. Enable 'Max. no. of connects per IP' set it at 1 18. Under 'Files' enable 'show relative path' this is a security issue. A FTP client will now not be able to see the ENTIRE path of the FTP.
interaction of computers and networks is the protocol. According to Merriam-Webster dictionary, a protocol is essentially a set of rules that define how computers communicate with other computers over a network (Merriam-Webster). There are many protocols that presently exist (e.g. HyperText Transfer Protocol, Internet Protocol), but one of the most useful protocols to users who have the desire of sharing files with one another may just be the File Transfer Protocol, or FTP. This paper is designed to explain
Even the beginning of the day started bad. I got up late for school and, with my luck had a test first hour. After getting to school and taking the test which seemed to be in a different language, I faced unpleasant customers for five long hours at work. Finally, being able to come home, flip of my shoes and sink my feet into our thick carpet was similar to what heaven must be. Switching into a pair of worn sweats and T-shirt I swiveled into the chair in front of my computer. With a press of a few
want to go to a website you have to type http://name of site.com? well I have been wondering for ages but still can't figure out, but sometimes you type ftp:// before the name of the site. This simply means File transfer protocol. You use this when download image files or any other files. Now, onto hacking. Most people stereotype people simply as "HACKERS," but what they don't know is that there are three different types of computer whizzes. First, there are hackers. Hackers simply make viruses
and image form, but some audio files also can be sent but with limited of file size. This application also is able to send the same message to several users at once. This is called broadcasting. The e-mail application using the standard protocol for sending emails namely Simple Mail Transfer Protocol (SMTP). While, the most commonly used protocol for e-mail receiving is Post Office Protocol v3 (POP3) and Internet Message Access Protocol (IMAP). The receiving protocol is used by email client to extract
The Secure Shell (SSH) is a protocol to use the network services with security. For example, when an email is send or receive, SSH will automatically encrypt or decrypt the email so that attacker will not intercept in the middle of the transaction [1]. There are two versions of SSH i.e. SSH1 and SSH2. SSH has 3 main components as shown in figure 1: Transport Layer Protocol that provide confidentiality, integrity and authentication; User Authentication Protocol that authenticate client to the server;
1. Introduction A penetration test is performed on a system in order to find security threats. The pen tester carries out the same tests a hacker would do. The hacker is looking for vulnerabilities in the computer and network in order to exploit them and gain access. The pen tester performs the same task but wants to find and fix any security threats without harming or compromising the system. The pen tester has permission to perform vulnerability checkes wheras the hacker does not. (Add more).
Auditing Tool's main function is to scan cisco routers to look for well known vulnerabilties. The tool accomplishes three main tasks which are, brute forcing the telnet password if telnet is running, it tries to brute force the Simple Network Management Protocol (SNMP) community strings, and finally it looks for the IOS history bug. (Ali and Heriyanto, 2011, p 144). Telnet is a program that connects a PC to the server or router on the network. The default port for telnet is 23. SNMP is a p... ... middle
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 mail services. It can also be noted that there is a significant amount of the broadcast packets like ARP, NBNS and UDP, as shown in figure 4.6 a partial segment of the Wireshark output and due to these packets the switches should experience
modify the protocol. In conclusion, to select the right VPN-solution for different environments can be a big challenge. Deciding which VPN-solution fit into a specific network can be difficult. The most important is to know the limitations and the differences of every protocol used in this purpose. References Forouzan, B. A. (2013). Data Communications and Networking. Connect Learn Succeed.

the various components and their respective operations, we must discuss the differences between the two. Fast Ethernet Network was developed as an upgrade to traditional Ethernet Networking. Fast Ethernet improved traditional Ethernet by increasing transfer rates 10 times, from 10 Megabit to 100 Megabit speed. Gigabit Ethernet Network is an upgrade on Fast Ethernet Network equivalent to Fast Ethernet Networks improvement over Fast Ethernet Network, offering speeds of 1000 Megabits (1 Gigabit). Gigabit
Operating System Proposal Linux has long been one of many operating systems that have been out to prove its worth in all types of environment. It is currently being considered for enterprise network purposes as well as data centers where it implies servers, workstations and any mainframes as needed. Choosing what operating system to use, whether it is open source or not, can be difficult, though. This paper projects the advantages and concerns of choosing an open source solution like Linux as
