Countermeasures and System Design of Campus Network Information Security Defense Based on Data Encryption Technology

Abstract

With the surge of educational informationization, campus network, as an important infrastructure of school informationization, takes on the tasks of school teaching, scientific research, management and foreign exchange. Due to many reasons, such as the uneven ability and level of equipment, users and managers, various security problems emerge one after another, and the information security of campus network directly affects all the work of the school. Computer system paralysis, campus network paralysis, state secrets, school secrets leakage, personal files damaged, changed, leaked and other issues make network security an important work in current network construction and network management, and it is also a problem that every individual who uses the network and computer should consider and pay attention to. Using data encryption technology to solve security risks has become a development upsurge of computer industry. This paper explores the current situation of campus network information security, and puts forward relevant suggestions according to the current specific situation, hoping to improve the security and reliability of campus network information.
