MLA Citation: The development and design of a basic web page can be a fun yet tricky task. Whether it’s a large commercial web page for business purposes, or a small personal web page about your hobby or family; the process of development is the same. The three major steps leading to the development and design of a basic web page include: information gathering accounting case study help, site layout and design, and HTML (hyper text markup language) conversion. The simple days of the firewalls ended when the Web exploded. Suddenly, instead of handling only a few simple services, firewalls now must be connected with complex data and protocols. Today’s firewalls have to handle multimedia traffic, attached downloadable programs (applets) and a host of other protocols plugged into Web browsers. This development has produced a basis conflict, the firewall is in the way of the things users want to do. A second problem has arisen as many sites want to host Web servers: Does the Web server go inside or outside of the firewall? Firewalls are both a blessing and a curse. Presumably, they help deflect attacks; but they also complicate users’ lives, make a Web Server Administration job a bit harder, rob network performance, add an extra point of failure paid homework help, cost money, and make networks more complex to manage. Prior to the invention of firewalls, routers were often pressed into service to provide security and network isolation. Many sites connecting to the Internet in the early days relied on ordinary routers to filter the types of traffic allowed into or out of the network. Routers operate on each packet as an unique event unrelated to previous packets, filtered on IP source, IP destination, IP port number essay on nature and nurture, and other basic data contained in the packet header. Filtering does not constitute of a firewall because it does not have quite enough detailed control over data flow to permit building highly secure connections. The biggest problem with using filtering routers for security is the FTP protocol, which, as part of its specification, makes a callback connection in which the remote system initiates a connection to the client, over which data is transmitted. In conclusion, despite its size and rapid growth, the Web is still in its infancy as with the software industry. We are just beginning to learn how to develop secure software, and we are beginning to understand that for our future, if it is to be online, we need to incorporate security into the basic underpinnings of everything we develop. Today, no one method of Internet Security can stop a hacker from intruding on our privacy. The goal is that as time goes on and we increase our technological knowledge of the Internet, that we raise our standards of security in everything we do weather on our computers or on the Internet; Thus we will hopefully be more protected by what we enjoy so much, the Internet. Class 1 Digital IDs intended for casual Web browsing providing users with an unambiguous name and e-mail address within Verisign’s domain. A Class 1 ID provides assurance to the server that the client is using an identity issued by Verisign but with little guarantee about the actual person behind the ID. There are simple and advanced methods for ensuring browser security and protecting user privacy. The more simple techniques are user certification schemes, which rely on digital IDs. Netscape Communicator and Internet Explorer allow users to obtain and use personal certificates. Currently, a certification company called Verisign offers digital Ids that consist of a certificate of a user’s identity. The Digital IDs are divided into different types of classes of digital Ids, each represents a different level of assurance in the identity, and each comes at an increasingly higher cost. The assurance is determined by the effort that goes into identifying the person requesting the certificate. As the number of sites requiring simple authentication grows buy term papers college, so does the number of passwords that each user must maintain. In fact, users are often required to have several different passwords for systems in their workplace, for personal accounts, for special accounts relating to payroll and vacation, and so on. It is not uncommon for users to have more than six sites they visit that require passwords. The World Wide Web is the single largest, most ubiquitous source of information in the world, and it sprang up spontaneously. People use interactive Web pages to obtain stock quotes essay on formative assessment, receive tax information from the Internal Revenue Service essay about becoming an english teacher, check the local weather, consult a pregnancy planner to determine ovulation dates, conduct election polls, register for a conference, search for old friends, and the list goes on. It is only natural that the Web’s functionality, popularity, and ubiquity have made it the seemingly ideal platform for conducting electronic commerce. People can now go online to buy CDs activities for teaching essay writing, clothing, concert tickets, and stocks. Several companies, such as Digicash, Cybercash essay social stratification, CarParts.com, and First Virtual, have sprung up to provide mechanisms for conducting business on the Web. The savings in cost and the convenience of shopping via the Web are immeasurable. Where as most successful computer systems resulted from careful, methodical planning becoming a teacher essay, followed by hard work, the Web took on a life of its own from the very beginning. The introduction of a common protocol and a friendly graphical user interface was all that was needed to ignite the Internet explosion. The Web’s virtues are extolled without end, but its rapid growth and universal adoption have not been without cost. In particular samples of writing a research paper, security was added as an afterthought.
