A Brief Note On Peer And Peer Network

In this modern day and age of computing, networks are a huge part of IT. It is important now more than ever that data sent over any network, whether it be a LAN (Local Area Network) or WAN (Wide Area Network; The Internet) is kept safe, private (when required) and uninterrupted in

There is a mess of servers, switches, switches, and inward equipment firewalls. Each of the association's areas is working with diverse data advances and foundation IT frameworks, provisions, and databases. Different levels of IT security and access administration have been actualized and inserted inside their individual areas. The data engineering framework is maturing and numerous areas are running on antiquated fittings and programming. Additionally, the framework is woefully out-of-dated regarding fixes and overhauls which significantly expand the danger to the arrange as far as classifiedness, trustworthiness, and accessibility.

Individual users play an important role in any form of institution or organization but concerns are raised about the security. The network administrators clearly lay down a set of rules, regulations and protocols that an individual user has to agree accordingly upon which part of the resources and what class of service that the user can obtain.

In a client and server caches, an each server cache is managed in one distributed system tier by a number of server members, usually cache server processes. In a separate tier, clients maintain their own caches that automatically call upon the server side to set off cache to update the server with client updates. In addition, the clients can member to server events using both data key specifications and queries. The client/server topology can be extended to any number of tiers.

6. Why is Ethernet technology more appealing to users than the rest of the LAN technologies?

The First World Bank Savings and Loan network infrastructure update will be Linux based. The bank will utilize a custom kernel designed with the input of a Linux Security consultant. This proprietary kernel is adaptable, scalable and modular to readily handle the bank’s network. This kernel was collaboratively developed by the bank’s Security and IT directors with a consulting firm that specializes in Linux network security.

With working with a Peer to Peer (P2P) network, it’s a type of approach used in computer networking that means every computer will share responsibility for any data processing. This type of networking is common in small local LANs (local area networks), typically found in home networking and even small businesses. This type of network can be wireless and even

Security is the heart of internetworking. The world has moved from an Internet of implicit trust to an Internet of pervasive distrust. In network security, no packet can be trusted; all packets must earn that trust through a network device’s ability to inspect and enforce policy. Clear text (unencrypted data) services represent a great weakness in networks. Clear text services transmit all information or packets, including user names and passwords, in unencrypted format. Services such as file transfer protocol (FTP), email, telnet and basic HTTP authentication all transmit communications in clear text. A hacker with a sniffer could easily capture user names and passwords from the network without anyone’s knowledge and gain administrator access to the system. Clear text services should be avoided; instead secure services that encrypt communications, such as Secure Shell (SSH) and Secure Socket Layer (SSL), should be used. The use of routers and switches will allow for network segmentation and help defend against sniffing

Security is almost certainly the most difficult aspect of a network to perfect. It is important to have the correct procedures and components in place to make certain network security is being accounted for and addressed on any given network. The journal, “Future Generation Computer Systems” elaborates on this necessity for an information system. “Future Generation Computer Systems”, this component of a network is discussed thoroughly. “Essentially securing an Information System (IS), involves identifying unique threats and challenges which need to be addressed by implementing the appropriate countermeasures” (Dimitrios Zissis, Dimitrios Lekkas, 2012). This was achieved through configuring access lists as well as CHAP configuration on the routers connecting to the edge

The Apache Web server has a well established group dedicated to the discussion, identification, and correction of any security risk one might find in their software systems. By working with the dedicated teams at the Apache project center one learns “how to configure the product securely; and find out if a published vulnerability applies to the version of the Apache product you are using; if a published vulnerability applies to the configuration of the Apache product you are using; obtaining further information on a published vulnerability; the availability of patches and/or new releases to address a published vulnerability” (Apache). Cisco also offers more than enough information to configure the ASA 5510 Adaptive Security Appliance for the most secure VNP connections connected to the local network and the data stored within its boundaries. The greatest number of complaints made about computers and computer programs are that they run slowly and they produce inaccurate information. Research in technology is ongoing and improvements in these areas are apparent.

Technologies and processes not within the scope are; the coordination for Type III and above encryption and keying material and coordination for National Security Agency (NSA) communications security (COMSEC) requirements. New networking or information systems technology will not be introduced into the scope of this project unless it provides necessary network security features for the prescribed protection.

This paper serves to direct the development team along a pathway of security, with the intent to share information about the most secured manner to implement this project. It must first be acknowledged that for information to be secured, information security must be integrated into the SDLC from system inception. The early integration of security in the

Peer-to-Peer file sharing is a more unorthodox way of obtaining files because instead of going through a web browser to get files, computer users use software such as Limewire and Vuze to access the files on other user’s computers. These file sharing software find as many computers as they can with the files that they are looking for, divide up the information necessary among the computers, and download a fraction of information from each computer. Each computer is given the title “peer” if it is utilized in the

Not everyone thought this was such a great idea, however. Some objections cite legal or moral concerns. Other problems were technical. Many network providers, having set up their systems with the idea that users would spend most of their time downloading data from central servers, have economic objections to peer-to-peer models. A long-established fixture of computer networking that includes important peer-to-peer components is Usenet, which has been around since 1979. Usenet news implements a decentralized model of control that in some ways is the grandfather of today’s new peer-to-peer applications such as Gnutella* and Freenet*. Fundamentally, Usenet is a system that, using no central control, copies files between computers. So the bottom-line is that file-sharing has been around for a long time now and that its decentralized nature makes is hard to control besides holding each individual sharing files accountable. Peer-to-peer systems go hand-in-hand with decentralized systems. In a fully decentralized system, not only is every host an equal participant, but there are no hosts with special facilitating or administrative roles. In practice, building fully decentralized systems can be difficult, and many peer-to-peer applications take hybrid approaches to solving problems. [1]

Miller Inc. which is in the business of providing data collection and analytics services relies majorly on network security to keep its competitive advantage. This is because the customers that rely on the company's system trust that since there are sufficient security measures that have been ensured, they can store their data securely. Each of the functional models of the system should have sufficient security measures to ensure that complete security of the whole system architecture is achieved. The three functional modules are the backend module, services or operation module and customer access module. The major relationship between infrastructure and security comes in the role they play to ensure that the end user gets the data that they need when they need it and in the best way possible. Therefore for the three modules, there is a need to balance security with the right infrastructure.
