Information-technology security becomes even more important when operating a business online. It’s critical to take the steps necessary to protect an online business against hackers who could steal vital information, or viruses which could bring your computer system – and your business — to its knees. Of course no system is foolproof. If someone is absolutely determined to break into your system, given enough time and money, they likely can. But it’s wise to put as many safeguards in place as possible, so that hackers will look for easier targets. What follows is a few steps security specialists recommend that business owners take to protect their systems.

1. St paul community college mn. Change default passwords and account names in place when your computer system was installed. Installing a machine or software out of the box without reconfiguring it for security is one of the most common security mistakes that online businesses make, but it’s one that’s easily corrected. Failing to make these changes makes it simple for hackers to gain access since they know or can determine what these original settings are.

2. Update your computer operating systems. Manufacturers upgrade security safeguards often. Sign up for the automatic updates that install security patches. Hackers often are on the lookout for systems that don’t have the latest safeguards. And look into anti-virus software, again with automatic updates. Software should also be put in place to block spam and detect spyware, the programs that can be surreptitiously installed from outside a computer system and feed sensitive information to the intruder.

3. Use encryption software to protect customers’ financial information from theft during transactions. Visa USA and MasterCard International Inc. require most businesses operating online to verify that they have taken a number of steps, including data encryption, to protect customers who use their credit cards. If you meet those requirements, your online operation is likely to be fairly secure.

Complying with the letter of those standards can be challenging for small businesses, which generally don’t have the resources or the security expertise of larger operations. So it can be a good idea to outsource payment processing to a company like eBay Inc.’s PayPal unit. Ensuring compliance for in-house payment processing can cost at least twice as much as outsourcing.

Encryption is also important for protecting a company’s internal information — personnel files, financial accounts and product information and other data. It can foil a hacker who has gotten into the company’s computer system but can’t decipher the information.

4. Limit access of sensitive information to those who need to see it. Special software can detect unusual patterns of activity in the computer system. There is also software that can monitor outbound communications to make sure certain information isn’t leaking out. For businesses whose employees need remote access to the company computer system, require more than just a user name and password to gain access — for instance, a token that displays a second password that changes regularly.

If these dangers don’t provide enough to worry about, a new concern is emerging about personal smart phones, mobile devices that can handle email and Web surfing. Private phones are more vulnerable to hacker attack than ones connected to a company network. A number of companies are introducing inexpensive mobile software that encrypts email traffic, or monitors phones for suspicious activity. While the threats have been minimal and more of an annoyance so far, they are something to keep an eye on.

Internet, a system architecture that has revolutionized communications and methods of commerce by allowing various computer networks around the world to interconnect. Sometimes referred to as a “network of networks,” the Internet emerged in the United States in the 1970s but did not become visible to the general public until the early 1990s. By 2020, approximately 4.5 billion people, or more than half of the world’s population, were estimated to have access to the Internet.

What is the Internet?

The Internet is a vast network that connects computers all over the world. Through the Internet, people can share information and communicate from anywhere with an Internet connection.

Who invented the Internet?

The Internet consists of technologies developed by different individuals and organizations. Important figures include Robert W. Taylor, who led the development of the ARPANET (an early prototype of the Internet), and Vinton Cerf and Robert Kahn, who developed the Transmission Control Protocol/Internet Protocol (TCP/IP) technologies.

How does the Internet work?

The Internet works through a series of networks that connect devices around the world through telephone lines. Users are provided access to the Internet by Internet service providers. The widespread use of mobile broadband and Wi-Fi in the 21st century has allowed this connection to be wireless.

Is the Internet dangerous?

The advent of the Internet has brought into existence new forms of exploitation, such as spam e-mail and malware, and harmful social behaviour, such as cyberbullying and doxxing. Many companies collect extensive information from users, which some deem a violation of privacy.

What is the Dark Web?

The Dark Web refers to a series of Web sites that require special decryption and configuration tools to access. It is most commonly used for purposes that require strict anonymity, including illegal sales (e.g., of weapons and drugs), political dissent in countries with heavy censorship, and whistleblowing.

Who controls the Internet?

While the Internet is theoretically decentralized and thus controlled by no single entity, many argue that tech companies such as Amazon, Facebook, and Google represent a small concentration of organizations that have unprecedented influence over the information and money on the Internet. In some countries, certain parts of the Internet are blocked via censorship.

The Internet provides a capability so powerful and general that it can be used for almost any purpose that depends on information, and it is accessible by every individual who connects to one of its constituent networks. It supports human communication via social media, electronic mail (e-mail), “chat rooms,” newsgroups, and audio and video transmission and allows people to work collaboratively at many different locations. It supports access to digital information by many applications, including the World Wide Web. The Internet has proved to be a spawning ground for a large and growing number of “e-businesses” (including subsidiaries of traditional “brick-and-mortar” companies) that carry out most of their sales and services over the Internet. (Seeelectronic commerce.)

Early networks

The first computer networks were dedicated special-purpose systems such as SABRE (an airline reservation system) and AUTODIN I (a defense command-and-control system), both designed and implemented in the late 1950s and early 1960s. By the early 1960s computer manufacturers had begun to use semiconductor technology in commercial products, and both conventional batch-processing and time-sharing systems were in place in many large, technologically advanced companies. Time-sharing systems allowed a computer’s resources to be shared in rapid succession with multiple users, cycling through the queue of users so quickly that the computer appeared dedicated to each user’s tasks despite the existence of many others accessing the system “simultaneously.” This led to the notion of sharing computer resources (called host computers or simply hosts) over an entire network. Host-to-host interactions were envisioned, along with access to specialized resources (such as supercomputers and mass storage systems) and interactive access by remote users to the computational powers of time-sharing systems located elsewhere. These ideas were first realized in ARPANET, which established the first host-to-host network connection on October 29, 1969. It was created by the Advanced Research Projects Agency (ARPA) of the U.S. Department of Defense. ARPANET was one of the first general-purpose computer networks. It connected time-sharing computers at government-supported research sites, principally universities in the United States, and it soon became a critical piece of infrastructure for the computer science research community in the United States. Tools and applications—such as the simple mail transfer protocol (SMTP, commonly referred to as e-mail), for sending short messages, and the file transfer protocol (FTP), for longer transmissions—quickly emerged. In order to achieve cost-effective interactive communications between computers, which typically communicate in short bursts of data, ARPANET employed the new technology of packet switching. Packet switching takes large messages (or chunks of computer data) and breaks them into smaller, manageable pieces (known as packets) that can travel independently over any available circuit to the target destination, where the pieces are reassembled. Thus, unlike traditional voice communications, packet switching does not require a single dedicated circuit between each pair of users.

Commercial packet networks were introduced in the 1970s, but these were designed principally to provide efficient access to remote computers by dedicated terminals. Briefly, they replaced long-distance modem connections by less-expensive “virtual” circuits over packet networks. In the United States, Telenet and Tymnet were two such packet networks. Neither supported host-to-host communications; in the 1970s this was still the province of the research networks, and it would remain so for many years.

DARPA (Defense Advanced Research Projects Agency; formerly ARPA) supported initiatives for ground-based and satellite-based packet networks. The ground-based packet radio system provided mobile access to computing resources, while the packet satellite network connected the United States with several European countries and enabled connections with widely dispersed and remote regions. With the introduction of packet radio, connecting a mobile terminal to a computer network became feasible. However, time-sharing systems were then still too large, unwieldy, and costly to be mobile or even to exist outside a climate-controlled computing environment. A strong motivation thus existed to connect the packet radio network to ARPANET in order to allow mobile users with simple terminals to access the time-sharing systems for which they had authorization. Similarly, the packet satellite network was used by DARPA to link the United States with satellite terminals serving the United Kingdom, Norway, Germany, and Italy. These terminals, however, had to be connected to other networks in European countries in order to reach the end users. Thus arose the need to connect the packet satellite net, as well as the packet radio net, with other networks.
