Security With Computers
Computer Security, techniques used to protect single computers and a network of computers from harm. In buisnesses and in schools the network administrator secures the network with different software. In Windows 95 & 98 there is a built in program called Policy Editor which you can use to secure your system. This will prevent physical loss of data, deception of computer users and the deliberate invasion of databases by unauthorized individuals.
PasswordsPasswords are used to give approved users access to computers. To work, passwords can not be easy to guess. Effective passwords contain a mixture of characters and symbols that are not real words.
FirewallsComputer networks, many computers linked together, are particularly vulnerable to computer crimes. Information on networks can be protected by a firewall, a computer placed between the networked computers and the network. It prevents unauthorized users from gaining access to the computers on a network, and it makes sure that information received from an outside source does not contain computer viruses, or programs that interfere with a computer's functions.
AvailabilityComponents such as floppy or hard disks are easy to damage. A computer's memory can be erased or the computer's hardware can be damaged by flooding, fire, or dust. To make sure this does not happen make several backup copies of data and store in another location.
