Introduction There are more Web application vulnerabilities than one can even count, and they have become so widespread that most hacking sites have tools that you can download to search, find, and exploit tools these vulnerabilities. This makes it very easy for even a rookie hacker to exploit these flaws. The three common web application vulnerabilities and attacks are as follows: Username enumeration, Security misconfiguration, and SQL Injection. Three common Web application vulnerabilities and attacks
architecture that organized as a set of services and associated server and clients access these services. According to that, client/server is suitable for representing this computing. Client/server is a distributed software architecture in which systems are divided into autonomous processes, where a client sends requests to a server and that server sends responses as an answer to the request to that client[1]. When creating a distributed client/server system there are several strategies on can use to divide
Client/Server Architecture and Attributes The client/server software architecture is a versatile, message-based and modular infrastructure that is intended to improve usability, flexibility, interoperability, and scalability as compared to centralized, mainframe, time sharing computing. A client is defined as a requester of services and a server is defined as the provider of services. A single machine can be both a client and a server depending on the software configuration. This technology description
nothing can introduce them or identify them but a digital certificate that is authenticated for the server. Thus, in order to prove your identity in electronic transactions, just as a driver license or a passport does in face-to-face interaction, came the need to create Digital Ids that are instrumental in establishing a secure channel for communicating any sensitive information back to the server. In this way, every document or data or information sent to friends, associations, firms... are authentic
Unix box to accommodate the volume and processing demands your bean-counters have projected for you. You'd run Sun Microsystem's Solaris software on it to power your Web server and e-commerce applications. Or, you could opt to save a little venture capital and run Linus Torvalds' free operating system (and its accompanying free server apps) on a cluster of commodity Intel PCs. The Linux OS is well-suited to small- to medium-sized operations, and is increasingly being used in large enterprises that

Active monitoring arrangements empower issue ID it can figure out whether a site or application is moderate or encountering downtime inside of minutes of the event. Moreover, by observing from an outside viewpoint, active monitoring empowers
Windows 2000. To put an end to these problems, Microsoft changed Windows 2000 memory management to reduce the chance that software applications will interfere with one another. In addition, Windows 2000 includes a built-in safeguard called Windows File Protection. This feature helps prevent critical operating system files from being deleted or altered by users or applications. Industry studies show that as much as 80 percent of system failures can be traced to human errors or flawed processes. If a
Introduction This paper will compare and contrast five different database management systems on six criteria. The database management systems (DBMS) that will be discussed are SQL Server 2000, Access, MySQL, DB2, and Oracle. The criteria that will be compared are the systems’ functionality, the requirements that must be met to run the DBMS, the expansion capabilities – if it is able to expand to handle more data over time, the types of companies that typically use each one, the normal usage of the

is how Napster works: 1.) A user sends a request for a song. 2.) Napster checks its database of music to see if the song is on the PC hard-drive of another Napster user whose computer is turned on (Note: No music is stored on Napster servers). 3.) Napster finds the song. 4.) Napster sends the song in MP3 format to the user who requested On December 6, 1999 the record industry sued Napster in Federal District Court for copyright infringements, and petitioned that court to
In this modern times a revolution is taking place. Quietly this revolution has started and grown that it involved the world. A revolution is a sudden change in the way people live (Merriam-Webster). The birth of computer networking started during the early 1970's and began to flourish during the late 1970's. Various manufacturers in the computer industry launched small minicomputers with enough computational power to cater the needs of several users. Because of the cheap prices of such computers
have been used for panning, implementation, designing, educating, inventing and even solving day to day life problems. Computer usage has increased over the last few decades due to the availability and accessibility of computers and internet based applications. While the question of whether people are over-dependent on computers may vary from individuals to groups of people, I think that computers have been too involved in the lives of people and vice versa. As much as computers make the life of humans
commercial, and institutional networks all compose parts of the internet. This network is connected to each other by either telephone wires, cable lines, or satellite signals. These wires, lines, or signals are then pipelined from server computer to server computer until your host server transmits the electronic information into your computer. The governing body of the internet is the Internet Society (ISOC).[4 Krol] The Internet Society purpose, according to Ed Krol, is to “promote global information exchange
more aware and threatened by the fact that their computers are prone to attack. Virus scanners are becoming necessities on all machines. Installing and monitoring these virus scanners takes many man hours and a lot of money for site licenses. Many server programs are coming equipped with a program called "netlog." This is a program that monitors the computer use of the employees in a company on the network. The program monitors memory and file usage. A qualified system administrator should be able
your Internet server provider may provide you with a SLIP connection so that the provider's server can respond to your requests, pass them on to the Internet, and forward your requested Internet responses back to you. A better service is provided by the Point-to-Point Protocol (PPP). Point-to-Point Protocol is a protocol for communication between two computers using a serial interface, typically a personal computer connected by phone line to a server. For example, your Internet server provider may
a dedicated, centrally managed, secure information infrastructure, which enables any-to-any interconnection of servers and storage systems. A SAN can be configured to provide a nearly infinite pool of storage that you can grow and move between servers as they need it. The storage can be added to and removed without requiring the server to be rebooted. The services provided by the server continue to operate without interruption. The primary purpose for implementing a SAN is to provide a large storage
Introduction Supercomputers is founded at 1960s by Seymour Roger Cray at control data coportation, and it have been used for science and design. Supercomputers is the fastest computer among all computers such as embedded computers, personal comnputers, servers and mainframes. Supercomputers have high speed and large amount of processors in it. Supercomputers are used for large companies or corporation. Supercomputer speed are measured in FLOPS or floating point instructions that supercomputers cann complete
Planning Your Proxy Server Implementation A key factor in determining the success of any installation is planning. Planning involves several phases-from understanding your current capabilities, to determining your current needs, anticipating your future needs, and, ultimately, finding a viable solution. We have all been in situations where the immediate need surpassed the need for planning and the installation was rushed. More often than not, the installation had to be repeated to correct problems
