Computer Fraud and Abuse Act Essay Example | Topics and Well Written Essays - 750 words

PC Fraud and Abuse Act - Essay Example This alludes to the inclusion of the administrative government’s PCs or endorsed money related bodies in examples where the carried out wrongdoing is of an interstate nature. To explain the arrangements of the first Act further, dealing in passwords, rebuking administration assaults and pernicious dissemination of codes was additionally condemned by the CFAA. The Act likewise experienced a few changes in an offer to wipe out covers and fill escape clauses somewhere in the range of 1989 and 2008. With models, this paper will scrutinize the authentic impact of the CFAA: Has it been a triumph or disappointment in forestalling PC misrepresentation and misuse? This inquiry is driven by the ambiguity of the law, which has the capability of presenting it to defects and prosecutorial misuse. According to its, the Act can be seen from two edges as far as the PCs it covers (Granville, 2003). The secured PCs are alluded to as ensured PCs, and in this sense, hypothetically, an ensured PC is characterized as one implied for selective use by the administration of the United States or by a monetary organization. It likewise alludes to whatever other PC which utilizes the legislature or money related foundation is harmfully influenced by direct that establishes an offense. This incorporates PCs not inside the United States, which influence remote or interstate correspondence and business of the United States. ... Since Congress didn't depict plainly what was implied by that, it brings up issues with regards to whether examiners will be of the feeling that a violator of terms of administration of a site merits time in prison or not (Jarrett and Bailie, 2010). Would such a supposition be sensible or too much cruel? Further, does the law need to isolate the manner in which it treats criminal aims on the Internet that bring about grave damage to the security of social, city, and monetary organizations based on what is viewed as ordinary Internet action? In the light of the current scramble for the Internet, legislators need to evaluate the adequacy of the CFAA and choose how to react to different partners and invested individuals. For example, some remote nations are looking for command over the Internet; influential people and corporate associations need it formed in manners helpful to them while subverting national interests; military systems are spying, assaulting and mistreating both private and open foundations; and insight and law upholding offices are trying to screen and mine it (Jarrett and Bailie, 2010). An examination of these zones will empower officials to decide the achievement or disappointment of the CFAA up until now, and whether changes are required. In the across the board case of the Aaron law, it is available to contention whether Aaron Swartz perpetrated a felony by downloading content from JSTOR, a notable chronicle for scholastic records, on which he had a record.

The son of Jewish immigrants from Poland, he spent a year at Brooklyn College and graduated from the Univ. of Chicago (B.A., 1964). He moved to Vermont in 1964. A sometime journalist, carpenter, writer, and filmmaker, he taught at Harvard (1989) and Hamilton College (1989â€"90). Sanders, a self-described democratic socialist, ran unsuccessfully for the U.S. Senate in the early 1970s and for Vermont governor in 1972, 1976, and 1986. First elected mayor of Burlington in 1980, he proved to be popular and effective. In 1990 he was first elected to the U.S. House of Representatives, becoming the first socialist to serve in that body since the 1920s. Officially considered an independent, Sanders was elected (2006, 2012) to the Senate, where he has generally espoused liberal and progressive positions while assiduously avoiding the label of Democrat. In 2015, however, he became a candidate for the 2016 Democr atic presidential nomination, mounting a long, vigorous, but ultimately losing campaign against Hillary Clinton .

Essay on Believing in Gods Existence - 2053 Words

Believing in Gods Existence Theism is a reasonable idea. Theologians have traditionally used several philosophical proofs in arguing for the existence of God. In my paper I will briefly discuss different arguments that have been used to prove Gods existence. These are as follows: Cosmological; Teleological; Ontological; Religious Experience and Evil. These arguments are not always persuasive, but that probably says as much about us as it does about the arguments. People most often reject God for reasons other than logic. These arguments, however, do provide insights that, while not proving the existence of God, do provide insights that may be used to show evidence of His existence. How†¦show more content†¦This is proof of the existence of a perfect and consistent God. When you see a tree with its branches waving in the wind do you believe there is a wind out there blowing the branches of the tree? You cannot see the wind, but you can see what it does, and so you know it is there. We can use the same example with air. We know that there is air all around us. Through science we know we cannot survive without it. We cannot see it, but we breathe it in and let it out of our lungs, and it keeps us alive. We know it is there because we know what it does. The first argument I will talk about will be the Cosmological argument. It attempts to prove God exists through features of the universe, such as causes and effects. Thomas Aquinas is one of the most famous philosophers to argue for the existence of God in this way. In fact, he has five arguments but I will only discuss two of them. In the first he notes that everything in the world has a cause. Nothing has ever caused itself. We can look back at events through history and determine exactly how they came about. But Aquinas says this process cant simply have been going on forever. We do not live in an infinite world. Therefore there must have been a first cause, something infinite that did not need to be caused itself, but that has setShow MoreRelatedThe Debate Of God s Existence1671 Words   |  7 PagesWe are told to follow certain norms or otherwise the big guy upstairs will punish us for being â€Å"disobedient†.

Capital Punishment Not Cruel and Not Unusual Essay

Capital punishment and the practice of the death penalty is an issue that is passionately debated in the United States. Opponents of the death penalty claim that capital punishment is unnecessary since a life sentence accomplishes the same objective. What death penalty opponents neglect to tell you is that convicted murders and child rapists escape from prison every year(List of prison escapes, 2015). As I write this essay, police are searching for two convicted murders who escaped from the Clinton Correctional Facility in New York on June 6th, 2015. The ONLY punishment from which one cannot escape is capital punishment. As the world is changing, so are people’s views on the death penalty. Some think that it does not†¦show more content†¦Throughout time, people were executed for various crimes such as: not confessing to a crime, stealing, cutting down a tree, marrying a Jew, killing chickens, being a spy, striking one’s mother or father, murder, and much more ( deathpenaltycurriculum.org). In a study I did, 50% of them thought the death penalty was cruel and unusual. Out of the 15 that thought it was cruel and unusual, 11 said that murderers and or rapists should get the death penalty. Capital Punishment has been around for so long it doesn’t need to be outlawed, just revised a little more like it has been as the years passed. Racism is often an excuse people use to say how unfair the death penalty is against African Americans. This excuse has been proven false in a few studies. More white murderers have been put to death since 1976 then black murderers, showing that the death penalty is not unjust to African Americans and minorities (Fisanick 26).In contrast, almost half of the criminals, on death row are black. Even though that is the case, blacks commit more murders than whites making it proportional (deathpenaltycurriculum.org). Criminals should not be given a lighter or harsher sentence due to their race, but due to the crimes that they committed and the severity of them.

Social Commentary On 13 Reasons Why - 1351 Words

Social Commentary on 13 Reasons Why In 2007, Jay Asher released the young adult novel 13 Reasons Why. It steadily gained popularity; it made the New York Times Bestseller List in 2011. In early 2017, Netflix took off with it and produced a 13-episode series. The story follows the suicide note (or rather, audio cassette tapes) left behind by high schooler Hannah Baker after she killed herself. Respected social figures and celebrities quoted the show and opened discussion about topics like depression, rape culture, bullying, and most obviously, suicide. On the thirteen tapes, Hannah walks the audience through the events and actions that led to her taking her own life, with each tape specifically about one of the thirteen people that she†¦show more content†¦But her relationship with them doesn’t seem to be one of mutual trust and communication. She explained that when their career lives got difficult and busy, her relationship with them dwindled. She said they talked to her, but not like before. They let their work take precedence over investing in their daughter, and beneath their disinterest and oblivion, she fell apart. She already accepted that they aren’t her best option to address her problems; her mom didn’t even notice her haircut, never mind her emotional deterioration. 13 Reasons Why exhibits uninvolved parenting and the way it can impact, or rather, not impact, teens’ lives. Additionally, Hannah only utilized the authorities in the school (to whom youth facing issues like hers are encouraged to come to) as a last resort, after she had already decided to take her own life. As previously mentioned, she went to talk to Mr. Porter, her guidance counselor at school, in search of one last glimmer of hope. She discussed with him the sexual assault she suffered, among other hardships, and her desire to end her life. His response painfully disappointed her. He essentially told her that getting over it may be her best option, and she left agitated. She hoped he would follow and not let her go, realizing she was serious about suicide, but he didn’t.

An Overview of the File Transfer Protocol

Questions: 1.The address depletion of IPv4 and other shortcomings of this protocol prompted a new version of IP known as IPv6. Explain the advantages of this new IPv6 when compared to IPv4? 2. Migrating from IPv4 to IPv6 is known as the transition from version 4 to version 6 and requires formal strategies to handle this transition. Explain each of the strategies for this migration process using appropriate examples? 3.Calculate the approximate bit rate and signal level(s) for a 4.2 MHz bandwidth system with a signal to noise ratio of 170?) 4.In a peer-to-peer (P2P) network, Internet users that are ready to share their resources become peers and form a network. Describe the differences between centralised and decentralised P2P networks? Discuss the advantages and disadvantages of both networks? 5.What is the total delay (latency) for a frame of size 5 million bits that is being sent on a link with 12 routers each having a queuing time of 4 s and a processing time of 2 s. The length of the link is 2600 km, the speed of light inside the link is 2.2 x 108m/s, the link has a bandwidth of 6 Mbps. Which component(s) of the total delay is/are dominant? Which one(s) is/are negligible? 6.Briefly explain the working of FTP with a flow diagram. How does it differ from SCP? What are the security considerations in FTP? Answers: 1. IPv6 gives efficient Routing then IPv4: IPv6 lower the measure of directing tables and get to makes routing more productive and various levelled. In IPv6 networks, discontinuity is taken care of by the source device, as opposed to the router, utilizing a protocol for revelation of the path's maximum transmission unit (MTU). IPv6 is Efficient than IPv4 Packet Processing The IPv6s packet headers much efficient in handling of package than IPv4.It does not contain any IP-level checksum as IPv4. So the checksum is not calculated at each hopping of the router. As most link layer contain checksum and error capabilities, the IP level in IPv6 get rid if it. Most transport layer also have checksum that start the error detection. The Data Flows rate of IPv6 is direct IPv6 supports multicast instead of communicate. Multicast grants data transfer capacity escalated parcel streams (like media streams) to be sent to various goal in the meantime, saving framework transmission transfer speed. The IPv6 header has another new field, named Flow Label, that can perceive parcels having a place with a comparative stream. IPv6 network config is simpler Address auto-design is characteristic to IPv6. A switch will send the prefix of the neighbourhood interface in its switch advertisements. A host can make its own particular IP address by tending to its connection layer (MAC) address, changed over into Extended Universal Identifier (EUI) 64-bit arrangement, to the 64 bits of the connection prefix. Security IPSec, gives privacy, verification and data integrity, that is prepared in IPv6. In view of their capability the convey of error, IPv4 ICMP bundles are frequently blocked by corporate firewalls, yet in ICMPv6, the usage of the ICM(Internet Control Message) Protocol for IPv6, may allow on the grounds that IPSec can be applied to the ICMPv6 packets. 2. There are mainly three strategies followed to migrate from IPV4 to IPV6.: Dual Stack Approach: As we realize that the data link layer closet room to Internet layer, on which IP protocol goes on. These link layers give access to the services to higher and lower layers. Along these lines, coordination between different layer are mandatory. Along these lines, migration should not influence the transport layer and upper higher layers. Along these lines, in this way one block is taken for IPV4 and another block is taken for IPV6. These block support coordination between each other after relocation. Transition of IPV6 and IPV4: IPV6 incorporates the support of interpretation of packet heads from IPV4 - IPV6. Those are completed by mapping IPV4 IP address to an exceptional subset of IPV6 IP address known as IPV4 translated address. These techniques evade the overheads that are given by double stack strategy. Tunnelling: On the reach of relocation of the data for IPV6 packets, destination address is encapsulated for the IPV4 packet. The network administrator takes different methods to tunnel, for example, arranged tunnelling, automatic tunnelling. In orchestrated tunnelling encapsulating packet consist of information for the recipient address of IPV6 bundles and in programmed burrowing the last goal address is managed by using an IPV4 good address of the IPV6 bundles. 3. To calculate the approximate bit rate and signal level: Given, Band width (B) = 4.2 MHz Sound to Noise ratio (SNR) = 170 Signal Level (C) = B log (1+SNR) 2 =4.2 * 10^6 log (1+170) =31.08 Mbps By Shannon Formulae, gives 31 Mbps For better performance, we choose 30 Mbps, then using Nyquist formulae, Bit Rate = 2*B*Log (C)2 =2*4.2*Log (30)2 =41.2 Mbps 4. Centralized P2P network, means hybrid network system. The Meta information about information and companions are secured on many "concentrated" server substances. These information sets may fuse parameters like the report availability, transfer speed, IP-addresses, inertia esteem, wt terrace. The data transmit is still dealt with in a decentralized strategy, direct from shared. In Decentralized shared p2p system, the data trade of these meta information must be administered without such especially described server framework. Like this manner, every communication handshaking is prepared in the peer that includes a data exchange for those meta data. By completing the handshaking process, every peer knows about its next peer. Centralized peer-to-peer network, way hybrid systems, and the Meta data of data/ information and the peers are placed on every centralized values of server. These information may issued parameters like the report accessibility, bandwidth, IP-addresses, inactiveness value, and so forth. In Decentralized peer-to-peer network, the statistics trade of those meta facts ought to be overseen without such very lots characterised server system. In like manner, every conversation handshake put together among the peer consists of a information alternate these meta data. by way of finishing the handshake system, every peer knows about its "neighbourhood". Advantages of centralized and decentralized peer to peer network are: Easy to set-up and keep up, Inexpensive and bring down cost, No additional speculation for server-software and hardware required. It will keep on operating regardless of the possibility that one of the workstation or resources are negative. Disadvantage of centralized and decentralized peer to peer network are: Security in the peer to peer is bad other than setting passwords for records that are not needed for individuals to get access to. If the links are not connected with the PCs then there can be issues getting to specific records for data. It does not run efficiently and effectively on number of PCs; it is best to utilized 2 to 8 number of PCs for peering. 5. We know, Latency = processing time + queue time + transmiting time + propagation time = 10 x 1 = 10 (s) = 10 x 10^-6 (s) Queuing time = 10 x 2 s = 20 s = 20 x 10^-6 (s) Transmiting time = 5,000,000 / 5 (Mbps) = 1 s Propagating time = 2000 (Km) / 2 x 108 (m/s) = 0.01 s Latency = 0.000010 + 0.000020 + 1 + 0.01 = 1.010030 s The ideal opportunity for transmission is predominant here as the parcel size is colossal, and preparing time and lining time are unimportant. 6. FTP is used in TCP for controlling and data connection. TCP mainly control connection for opening and closing of any on-going FTP session and for retrieving data from client to server. Each FTP uses many different data connection. Steps for FTP process: To open the control connection The Client opens a control connection with the server (TCP). This control connection is utilized for FTP commanding and FTP answering. The Data transfer then order the client to starts a file transfer. Then Data connection is used for exchanging another information connection is made for the exchange of those records. After the end of document transfer, the sender shuts down the information that TCP is associated with, when the record is totally transferred. At last when the transfer is complete, at the end of the FTP session, the control connection is closed, the control connection then shut down by the client. The differences of FTP to SCP are: SCP stands for Secure Copy Protocol whereas FTP stands for file transfer protocol. Both of this is used for file transferring but SCP is secure encrypted while FTP is plain text. SCP uses any port that is specified, whereas FTP mainly uses port 21 that help to sends the id/password in the format of plain text. SCP duplicate records to or from any associated remote servers utilizing a SSH channel. Other than SSH get to it runs a solitary duplicate charge FTP manages the records on a remote server, however it's security is to establish the security are not so strong, and thus permits access to the FTP root directory for login client account. The security considerations in FTP:- The following security risk must be undergoing while allowing FTP clients to access the system: Your object authority scheme would not give itemized enough security when the permit of FTP is followed on the framework. USE power to a document permits the client to download the record. CHANGE authority to a record permits the client to transfer the document. FTP checks the logon endeavours for every client profile the length of the QMAXSGNACN framework esteem is set to 2 or 3. This alternative debilitates the profile on the off chance that it achieves the greatest sign on number. Three is the default setting. In any case, the hacker utilizes this to mount a "denial of service" attack by means of FTP. A hacker can utilize FTP to impair client profiles on the system by over and again endeavouring to sign on with an incorrect password. This will happen until the client profile is incapacitated.
