Computer Network Security

The computer network security is a key issue to promote the development of trade in all areas. One word ‘security’ covers many different aspects, both technical, organizational and legal. Latitude users against security problems is often irrational, which does not help to simplify the discussion. The safety of paying by credit card over the Internet is part of controversial topics. In 1996 our experimental platform Infoway, we asked our 10,000 users to pay a participation fee for access. All means of payment were available on the server from the secure online credit card, send the card number by fax or check. Contrary to popular belief, approximately 60% of users chose the secure online payment, 30% and 10% check preferred to send the credit card number by fax which even provided a PIN! The perception of safety is an important element to consider in developing these systems.

From a technical perspective, safety covers both access to information on workstations, servers and network data transport. In this short paper, we focus on the problems of information security in trade through public or private networks. Internet, the network of networks, is a tool that allows all computers regardless of their type to communicate with each other. Technology (TCP / IP) has simplified the creation of networks, thus reducing the cost of telecommunications. However, the security features are not addressed by this protocol.

Giant Microsoft Will Buy the Phone Service Skype f...

Software giant Microsoft has announced today that it agreed to buy the online telephony service Skype for $ 8.5 billion $ U.S., its largest acquisition in 36 years of history.

The acquisition of Skype would offer Microsoft a potentially valuable tool for communication while the firm tries to increase its presence on the Internet and the smart phone market.

Skype is particularly held by the website and eBay auction fund Silver Lake. The service has 663 million users worldwide.

Microsoft wants to marry the functions of Skype with its Xbox game console, the mail program Outlook and Windows smartphones.

About 170 million people use Skype’s services each month. They spent over 207 billion minutes of voice and video communications in 2010.

Entrepreneurs Niklas Zennstrom and Janus Friis, who started the company in 2003, have struggled to make their business profitable since most people use Skype calling services for free. Approximately 8.8 million customers per month, only 5 percent of the total number of users pay for services.

The group would have lost $ 7 million last year for a turnover of U.S. $ 860 million. End of 2010, its long-term debt was U.S. $ 544 million.

The current CEO of Skype Tony Bates retain the head of the company.

Microsoft makes its biggest acquisition so, after the takeover in 2007 of technology providers for digital marketing Aquantive approximately U.S. $ 6 billion.

The site eBay acquired Skype in 2005 for U.S. $ 2.6 billion, but he never managed to combine phone service and bids.

He had sold 70 percent of its shares to an investor group led by Silver Lake funds Horowitz and Andreessen to U.S. $ 2 billion 18 months ago.
