Security on the Internet
How do you secure something that is changing faster than you can fix it? The Internet has had security problems since its earliest days as a pure research project. Today, after several years and orders of magnitude of growth, is still has security problems. It is being used for a purpose for which it was never intended: commerce. It is somewhat ironic that the early Internet was design as a prototype for a high-availability command and control network that could resist outages resulting from enemy actions, yet it cannot resist college undergraduates. The problem is that the attackers are on, and make up apart of, the network they are attacking. Designing a system that is capable of resisting attack from within, while still growing and evolving at a breakneck pace, is probably impossible. Deep infrastructure changes are needed, and once you have achieved a certain amount of size, the sheer inertia of the installed base may make it impossible to apply fixes.
The challenges for the security industry are growing. With the electronic commerce spreading over the Internet, there are issues such as nonrepudiation to be solved. Financial institutions will have both technical concerns, such as the security of a credit card number or banking information, and legal concerns for holding individuals responsible for their actions such as their purchases or sales over the Internet. Issuance and management of encryption keys for millions of users will pose a new type of challenge.
While some technologies have been developed, only an industry-wide effort and cooperation can minimize risks and ensure privacy for users, data confidentiality for the financial institutions, and nonrepudiation for electronic commerce.
With the continuing growth in linking individuals and businesses over the Internet, some social issues are starting to surface. The society may take time in adapting to the new concept of transacting business over the Internet. Consumers may take time to trust the network and accept it as a substitute for transacting business in person. Another class of concerns relates to restricting access over the Internet. Preventing distribution of pornography and other objectionable material over the Internet has already been in the news. We can expect new social hurdles over time and hope the great benefits of the Internet will continue to ove...

...o that its confidentiality and integrity are preserved. That is, the data remains secret to those who do not posses the secret key, and modifications to the cipher text can be detected during decryption. Two of the most popular symmetric ciphers are the Data Encryption Standard (DES) and the International Data Encryption Algorithm (IDEA). The DES algorithm operates on blocks of 64 bits at a time using a key length of 56 bits. The 64 bits are permuted according to the value of the key, and so encryption with two keys that differently in one bit produces two completely different cipher texts. The most popular mode of DES is called Cipher Block Chaining (CBC) mode, where output from previous block are mixed with the plaintext of each block. The first block is mixed with the plaintext of each block. The block uses a special value called the Initialization Vector.
Despite its size and rapid growth, the Web is still in its infancy. So is 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.
I must state at this point that much of this book’s content disturbed me, and I experienced great relief at its conclusion. Specifically, his pessimistic views on the Enlightenment,
In his Letter from Birmingham Jail, Martin Luther King Jr. uses his personal experience to convince others of the importance of revising the segregation laws that were in place during 1960’s. In paragraphs 13 and 14 in particular, there is a lot of language used to persuade the reader’s opinions and emotions toward King’s argument. He does this not only convince his fellow clergymen, but to inform others of the reality that African Americans faced in the 60’s.
The New Testament portion of the Bible is widely accepted as the book of hope, grace, love and forgiveness. However, the Old Testament also provides evidence of God’s grace and love for his people. Richard Dawkins opposes this view of the Old Testament God .Richard Dawkins in his book, The God of Delusion states that the God of the Old Testament is a God who is unjust, unforgiving, and vindictive amongst many other negative human nature attributes. Richard Dawkins view of God in the Old Testament is far from a God of grace and love. The God of the Old Testament is a God who desires to have a relationship with his people .God created covenant relationships throughout the Old Testament, starting with Adam and Eve, then through Noah, Moses, Abraham and David. According to Eugene Merrill “a covenant is a written agreement or a promise usually under seal between two or more parties”. The Hebrew word for covenant appears in the Old Testament 285 times. The Israelites throughout the Old Testament would consistently fall short of the agreed covenant regulations with God, and God would continue to provide ways to reconcile with Israel. The examples of this are abundant and can be found in each book of the Old Testament. According to Richard Dawkins the God of the Old Testament is unforgiving, unjust, and vindictive. However the scripture can prove that through Gods covenant agreements, God was a God of grace, love and a God who has an unsurpassable capacity for forgiveness.
A covenant has been defined as an agreement by two groups of people, one more powerful than the other, and the inferior group held accountable until the agreement or bond has been fulfilled or satisfied by the lesser of the two. The lesser of the two also agrees to remain loyal to the powerful or dominant and by the same token the powerful has the obligation to provide protection. In Abrahams late age God came to him with a covenant making him fertile and is to become the father and ancestor of many nations and which will bear many kings from generation to generation. The covenant included the circumcision of every man and child that was 8 days and older which gave everyone including God sign of acceptance of the covenant and those who did not accept the circumcision will be considered as not in agreement and will be cut from the covenant. God needed a figurehead and a strong willed person to lead his chosen people of Israel. Abraham was a strong authoritative figure in his family and had the qualities of a leader and teacher of good character. Abraham set the tone in the household and never let his children take control of any situation that demanded his attention. God was seeking for a man who would embrace the responsibilities of what God willed and would be faithful to the end.
In the passage quoted from Jeremiah above, the prophet is predicting that a new covenant would be formed between God and his people, an agreement that would supersede the pact made between Moses and God upon Sinai and at the Red Sea. The first covenant, Jeremiah indicated, would become null and void because of the sins of the Jewish people. The new covenant would absolve these sins and reaffirm God's fidelity to his people.

Asymmetric Encryption is used to protect the data while in movement. Asymmetric Encryption is also known as Public Key Encryption. It uses two related keys, a public key and a private key which is not shared with anyone. This pair of keys are developed by mathematical methods which can be solved in one direction. So anyone can encode a data using the public key but only the user with a private key can decode that specific data. The length of Asymmetric Key Encryption is normally 1024 or 2048 bits. However, in Asymmetric framework the keys with smaller than 2048bits are considered as not safe to use.
One of the largest parts of commerce is transaction. Transactions are needed anytime two parties exchange money or information. Since the Information Age has begun, transactions are more common over the Internet, where it is more imperative that transactions are secure (Klein x). Corporations have also become more widespread, which means that cryptography is needed to secu...
The internet has been one of the most influential technological advancements of the twenty-first century. It is in millions of homes, schools, and workplaces. The internet offers not only a way of communicating with people around the world, but also a link to information, shopping, chatting, searching, and maps. This freedom to be anyone and to "go" anywhere right from the comfort of home has become a cherished item. However, there is always a down side to every up. Because of the freedom to post anything and access anything on the internet, the issue of regulation has arisen; for example, what should and should not be allowed on the internet? Who has the right to regulate this space that we cherish for its freedom?
For thousands of years cryptography and encryption have been used to secure communication. Military communication has been the leader of the use of cryptography and the advancements. From the start of the internet there has been a greater need for the use of cryptography. The computer had been invented in the late 1960s but there was not a widespread market for the use of computers really until the late 1980s, where the World Wide Web was invented in 1989. This new method of communication has called for a large need for information security. The internet allows people to communicate sensitive information, and if received into the wrong hands can cause many problems for that person.
To combat those threats and ensure that e-business transactions are not compromised, security technology must play a major role in today's networks. Why Networks Must Be Secured? Attacks: -. Without proper protection, any part of any network can be susceptible to attacks or unauthorized activity. Routers, switches, and hosts can all be violated by professional hackers, company competitors.
In recent times we might consider that the right for privacy in one of our major achievements in our society. Unfortunately the same does not apply for the Internet. The Internet once considered a place for free information exchange and sharing, has the potential has becoming the biggest threat to its users. The commercialization of the Internet is one of the major reasons why the chances of a compromise of our privacy have increased. Customer profiling, address trading or simple lack of care with sensitive customer information are just some of the threats that this commercialization has bought to our ‘free’ Internet. Another reason being that with the increase of threats there is a regular change in technology to counter these threats. These changes make it harder for the already overstrained users to cope with the ever changing technology.
My aims are to require my evidence that will show me to understand of broad range of my learning outcomes in my project brief.
The consistent use of information and communication technology (ICT) in modern world enables us for countless opportunities for individuals, institutions, business organisations and scientists, but it also raises difficult ethical and legal problems. In particular, ICT helped to make societies more complex and thus even harder to understand. The use of ICT has led to changes in concepts: ownership, buying and selling, right to possession, theft, justice in the distribution of resources and access rights. During the nineties, the internet has grown into all business segments resulting in a large number of questions running. It has been noted that during those time period there has been merging of computers, telecommunications, and media which is further emphasized by the emergence of new issues and strengthening old ones.
growth in usage by both consumers and businesses. The unique capabilities of the Internet has captured the attention of the marketing community. While a growing number of companies have or are interested in developing an Internet presence, there is still a great deal of uncertainty about it and the potential ethical issues associated with its use as a marketing medium. Although many businesses are acknowledging the importance of a Web site, but the potential ethical issues related to marketing on the Internet still having an uncertainty in this situation. Much less attention has been given to the business community's perceptions of the ethicalness of this new medium. The unique interactivity of the Internet has captured the marketing community's interest as a way to develop and enhance customer relationships and establish greater brand identity. Thus, many commercial services have become available on the Internet that allow consumers and organizations to interact electronically. These services include booking airline tickets online, buying books and compact discs, and receiving stock market information. Although the number of consumer users and commercial organizations navigating on this "information superhighway" is growing almost exponentially, the benefits of the Internet are not without drawbacks.
