Computer Security

BACKUP
Storing backup copies of software and data and having backup computer and communication capabilities are important basic safeguards because the data can then be restored if it was altered or destroyed by a computer crime or accident. Computer data should be backed up frequently and should be stored nearby in secure locations in case of damage at the primary site. Transporting sensitive data to storage locations should also be done securely.
ENCRYPTION
Another technique to protect confidential information is encryption. Computer users can scramble information to prevent unauthorized users from accessing it. Authorized users can unscramble the information when needed by using a secret code called a key. Without the key the scrambled information would be impossible or very difficult to unscramble. A more complex form of encryption uses two keys, called the public key and the private key, and a system of double encryption. Each participant possesses a secret, private key and a public key that is known to potential recipients. Both keys are used to encrypt, and matching keys are used to decrypt the message. However, the advantage over the single-key method lies with the private keys, which are never shared and so cannot be intercepted. The public key verifies that the sender is the one who transmitted it. The keys are modified periodically, further hampering unauthorized unscrambling and making the encrypted information more difficult to decipher.
APPROVED USERS
Another technique to help prevent abuse and misuse of computer data is to limit the use of computers and data files to approved persons. Security software can verify the identity of computer users and limit their privileges to use, view, and alter files. The software also securely records their actions to establish accountability. Military organizations give access rights to classified, confidential, secret, or top-secret information according to the corresponding security clearance level of the user. Other types of organizations also classify information and specify different degrees of protection.
FIREWALLS
Computers connected to communication networks, such as the Internet, are particularly vulnerable to electronic attack because so many people have access to them. These computers can be protected by using firewall computers or software placed between the networked computers and the network. The firewall examines, filters, and reports on all information passing through the network to ensure its appropriateness. These functions help prevent saturation of input capabilities that otherwise might deny usage to legitimate users, and they ensure that information received from an outside source is expected and does not contain computer viruses.
Security software called intrusion detection systems may be used in computers to detect unusual and suspicious activity and, in some cases, stop a variety of harmful actions by authorized or unauthorized persons. Abuse and misuse of sensitive system and application programs and data such as password, inventory, financial, engineering, and personnel files can be detected by these systems.
APPLICATION SAFEGUARDS
The most serious threats to the integrity and authenticity of computer information come from those who have been entrusted with usage privileges and yet commit computer fraud. For example, authorized persons may secretly transfer money in financial networks, alter credit histories, sabotage information, or commit bill payment or payroll fraud. Modifying, removing, or misrepresenting existing data threatens the integrity and authenticity of computer information. For example, omitting sections of a bad credit history so that only the good credit history remains violates the integrity of the document. Entering false data to complete a fraudulent transfer or withdrawal of money violates the authenticity of banking information. These crimes can be prevented by using a variety of techniques. One such technique is checksumming. Checksumming sums the numerically coded word contents of a file before and after it is used. If the sums are different, then the file has been altered. Other techniques include authenticating the sources of messages, confirming transactions with those who initiate them, segregating and limiting job assignments to make it necessary for more than one person to be involved in committing a crime, and limiting the amount of money that can be transferred through a computer.
DISASTER RECOVERY PLANS
Organizations and businesses that rely on computers need to institute disaster recovery plans that are periodically tested and upgraded. This is because computers and storage components such as diskettes or hard disks are easy to damage. A computer’s memory can be erased or flooding, fire, or other forms of destruction can damage the computer’s hardware. Computers, computer data, and components should be installed in safe and locked facilities.

Advantages of Computer Games and Popular Computer Games

Advantages of Computer Games
Computers brought a new flexibility to electronic games. Because computers stored data, they made a good platform for lengthy adventure and role-playing games. Players could store their progress and continue the games at a later time. With consoles such as the Atari 2600, players could only start games from the beginning. This situation changed slightly in the mid-1980s, when Nintendo built a battery-backed chip into The Legend of Zelda that allowed players to record their progress.
Computer systems such as the Commodore Amiga and Apple Macintosh brought other advantages to gaming. These machines used mouse controllers, devices that gave players fast and highly precise control. As technology progressed, computer monitors offered higher resolution than television screens, giving computer games a crisper look. This improved resolution made computers ideal for running strategy games such as SimCity and Civilization, which featured highly detailed graphics.
Although some computer-game publishers dropped out of the business, others-such as Broderbund and Sierra On-Line-gained prominence. Electronic Arts, which was founded in 1982, became one of the biggest names in the industry. The company’s success was fueled by aggressively recruiting top game designers away from competitors and by packaging its games in attractive boxes.
In 1984 Electronic Arts paid professional basketball stars Julius Erving and Larry Bird $25,000 each to use their names and likenesses in a game called Dr. J and Larry Bird Go One-on-One. The game was an instant success, leading Electronic Arts to strike up a similar relationship with National Football League (NFL) announcer and former coach John Madden to create a football simulation game for the Apple II computer in 1989.
For many years personal computers (PCs) were plagued with compatibility problems that hampered them as a gaming platform. Because only Apple manufactured Macintosh computers, however, these machines had standardized parts and operating software. Programs that ran on one Macintosh computer could run on any Macintosh that had sufficient processing power. International Business Machines Corporation (IBM), Compaq, Packard Bell, and several other companies all manufactured different PC machines, seldom using standardized components. As a result, games that ran on one type of PC might not run on PCs made by other manufacturers.
Singaporean entrepreneur Sim Wong Hoo began to solve this problem in 1989 when he introduced a PC sound card called the Sound Blaster. Although other companies previously had released sound devices for PCs, Sim succeeded at establishing Sound Blaster as the standard for PC sound. Future sound cards needed to be “Sound Blaster-compatible,” meaning they needed to use the same software (often called drivers). Having a standardized sound protocol enabled PCs to run games with robust music and voice files that sounded as good or better than the audio in console games.
Popular Computer Games
In 1993 id Software published Doom, one of the most influential computer games of all time. Doom popularized a three-dimensional, first-person perspective camera-allowing players to see the game through the eyes of the character they controlled. The game also popularized online multiplayer gaming (playing with or against other people through LANs or the Internet).
In the early 1990s a drop in the price of CD-ROM technology led to a wave of multimedia games (games that combine audio, video, animation, photographs, or other media). Compact discs (CDs) can store from 650 to 700 megabytes of data, more than 400 times the storage space of standard floppy disks. With this extra storage, designers could add voice files, digitized video of live actors, and other assets to their games. Companies such as Digital Pictures, Access Software, and Viacom published interactive movies, or games that combined digitized footage of real actors and virtual sets.
In 1993 Broderbund published a game called Myst for Macintosh computers, and Virgin Interactive Entertainment published a game called The 7th Guest for the PC. In both games the player explores a rich virtual world, trying to solve puzzles. Millions of copies of these games were sold, popularizing multimedia technology and attracting large new audiences to computer gaming.
In 1995 Microsoft launched Windows 95, an operating system that further simplified the use of PCs as a gaming platform. With built-in driver support for sound cards, graphics cards, joysticks, and other controllers, Windows 95 removed most of the compatibility issues that had long plagued computer gaming.
The PC game market declined in the early 2000s as video-game consoles became more powerful, incorporating high-end graphics, hard drives, and Internet features that were formerly exclusive to home computers. Some popular console games continued to be simultaneously released for the PC, but others were designed solely for the console market.
