Security of Computer Network System



First, the importance of the network security. With the informationization developing fast today, the computer network obtained the widespread application, but along with the network information transmission capacity growing faster, some organizations and departments benefit the speedup with the service operation in the network, while, the data has also suffered to extent attack and destruction. The aggressor may intercept the information in the network, steals the user’s password, the database information; also may tamper with the database content, the forge user’s status, denies own signature.

Second,

network

security

rationale.

International

Standardization

Organization (ISO) once suggested the computer security the definition was: “The computer system must protect its hardware, the data not accidentally or reveals intentionally, the change and the destruction.” In order to help the computer user discrimination and the solution computer network security problem, the American Department of Defense announced “the orange peel book” (orange book, official name is “credible computer system standard appraisal criterion”), has carried on the stipulation to the multiuser computer system security rank division.

Third, the network security should have function. In order to adapt the information technology development well, the computer network application system must have following function:（1）Access control.（2）Inspects the security loophole.（3）Attack monitoring.（4）Encryption communication.（5）Authentication.（6）Backup and restoration.（7）Multi-layered defense.（8）Sets up the safe monitoring center.
