Advance DATA PROCESSING In Peer to Peer Technology With Peer++ Approach ABSTRACT: The corporate network is often used for sharing information among the participating companies and facilitating collaboration in a certain industry sector where companies share a common interest. It can effectively help the companies to reduce their operational costs and increase the revenues. However, the inter-company data sharing and processing poses unique challenges to such a data management system including scalability, performance, throughput, and security. In this paper, we present BestPeer++, a system which delivers elastic data sharing services for corporate network applications in the cloud based on BestPeer—a peer-to-peer (P2P) based data management
One way of making sure your server is secure it to enable the iptables. If unauthorized access is attempted, iptables (firewall) will ensure the access will be denied. Another way of securing the server is by using Secure Shell (SSH) which is a secure protocol. Any communication with the server is encrypted with SSH. SSH can be configured to restrict user access.
While transmitting and storing your test results it can be very critical. If it is possible try to encrypt the e-mails and files using Pretty Good Privacy (PGP) or something similar. Now you are on a reconnaissance mission. Try to harness as much information as possible about your organization and systems, which is what malicious hackers do. Start with a wider view and narrow your

Privacy Under Multiple Dependent Executions User Privacy: The client security of any PPFRVP calculation A measures the probabilistic favorable position that a foe an additions towards taking in the favored location of no less than one other client ,aside from the last fair rendez-vous location, after all clients have taken an interest in the execution of the PPFRVP protocol.
This gave the hackers an access to the computer network and a possibility to control it remotely. Barclays faced losses of £1.3 million. The first thing that must be done in order to avoid similar attacks is not much related to cyber security: it is more rigorous physical protection of the computers and servers. Since an attacker like above-mentioned has to firstly get physical access to one of the computers from the network, the first solution is to better control external workers, raise the standards of their inspection and ensure the best possible protection of technological equipment. Another security possibility is to examine every supplier of even the smallest parts of network equipment and to make sure they are reliable, cause their equipment is going to access huge amount of secret data.
Chapter 3 Single Path TCP Figure 3.1: TCP protocol is used by applications to communicate with each other over the internet. The TCP protocol is a connection oriented protocol.TCP provides reliable transmission of data in IP environment. .Services TCP pro- vides are stream data transfer,reliability,flow control and multiplexing .With stream data transfer,TCP delivers an unstructured stream of bytes identified 4 by sequence numbers.This service benefits applications because they do not have to chop data into blocks before handing it over to TCP.fig 3.1 shows how a single path TCP connection is established. 3.0.1 Disadvantages of A Single Path TCP 1)Offers less Reliability . 2)Less Load Balancing Capacity 3)Less Fault Tolerant .
People often use the same username and password for many different systems, so these stolen credentials may be used to access other systems not yet infected. Once access is gained, additional information theft or malware installation can take place. Another way spyware puts systems at future risk is by installing backdoor access mechanisms. These backdoors give the malware operator access to control the system or to command the system to download and run arbitrary applications. Attackers can build vast collections of compromised systems without originally compromising a single
The OLTP systems bring high speed, efficiency, economy and accuracy to operations, Management Information Systems (MIS) and Decision Support Systems (DSS). In an OLTP system within one premise of an organization all the data are kept in one or more databases on as many server computers, which are generally located far from the users. The user transacts with the computer database through his PC node on the Local Area Network (LAN). The software has to provide highly user-friendly interfaces to the user for his work. These interfaces are in the shape of ‘forms’, ‘menus’ or simple commands developed for the
