IP address

Introduction Nowadays, Internet becomes the most important thing in our life. Using mobile phone, computer, even game consoles, we need the Internet to connect with people to communicate all around the world while many unlimited information are shared in the Internet. Internet censorship is an important topic for users, which means the information and ideas are controlled within the society. Therefore, some of them are censored and not all can easily accessible online. The organization, even the…

access the internal service from outside. The unused and unsafe ports should be closed when they are not in use in case of the attacks through these ports. The blocking service prevents the DNS Spoofing, which is an attack to return an incorrect IP address as the response. Secondly, the firewalls restrict the service that are deemed unsafe from inside to outside. Blocking outbound traffic could limit the attackers’ actions once they are a composition if the network. The service prevents the ARP…

Each day through the use of emails, research, internet, and dating sites, personal information (Big Data, geolocation,) is being modified and introduced to third parties for consumption. According to Daniel J. Solove, the John Marshall Harlan Research Professor of Law at the George Washington University Law School, he states that in his article, one of the bloggers proclaimed: “Do I care if the FBI monitors my phone calls? I have nothing to hide. Neither does the 99.99 percent of the population.…

Student Name: Caroline machinjili THIRD YEAR DEGREE IN COMPUTING AT CCT DUBLIN SUBJECT: ADVANCED SWITHCING AND ROUTING PORTFAST AND ETHERCHANNEL October 2015 PORTFAST in my network I have setup portfast on all the 18 access switches connected to the workstations and also on the core switches connected to the servers. on both switches I have used ports fa0/1 to fa0/2. portfast on these ports will reduce the time the devices spend to connect to other devices on the network since these ports…

connection and being it the reason why response time is important. It cannot allow large latencies due to TCP connection structure. HTTP only transfers larger amount of data, and needs a genuine mechanism. DNS requests are short packets that issues the IP address for a name and maybe some other dependable name server addresses. The reliable protocol semantics of TCP would be costly in the DNS case. b) What could happen in DNS if its UDP based request or response packet is lost If DNS request…

To understand how I need to proceed with my chosen solution to the problem experienced by the Wayward Pines Public Library, I must first identify the current state of the computer at the library and then decided on the best methodology to accomplish my chosen solution. There is a total of 16 public access computers at the library which is for the specific use by library patrons to access the internet and the online card catalog. These 16 machines are set up in a secluded area of the…

Data privacy is an important topic among many people around the world. The idea of personal data being shared orally, online, or otherwise is a major source of concern. Some data is shared voluntarily, such as among family and friends within social networks, and some is involuntary, such as when organizations trade personal data like currency. Organizations that collect data without prior notification are potentially putting people at risk for years of turmoil from problems such as identity…

4. CONTROLLING IP SPOOFING IP addresses are unique addresses used to identify a node on the network. But the attackers have been able to fake or spoof their IP addresses masquerading as someone else while they do the malicious work, and this in a sense defeats the point of having an address system for uniquely identifying everyone. Thus considerable research is being carried out to detect such digital impostors and reveal at the very least stop them from accessing the resource if the spoofing…

The important characteristics of IR is that it can’t penetrate walls or other opaque materials. Typically, with an IR-based system, a receiver is placed in every location in which a tagged device might be found. The tagged device emits IR light, and if the tagged device is in the same room as a receiver its position is known. The major advantage of an IR-based system is that as the oldest and most installed positioning technology, solutions are generally available from a variety of sources…

offer access to some Internet services. It is also possible to gain access through a commercial Internet Service Provider (ISP). The Internet is a global system of interconnected computer networks that use the standard Internet protocol suite (TCP/IP) to serve billions of users worldwide. It is a network of networks that consists of millions of private, public, academic, business, and government networks, of local to global scope, that are linked by a broad array of electronic, wireless and…
