在信息时代内,各行业都不可脱离计算机,网络技术被融入多样的现存领域。计算机网络增添了平日生活及生产的更多便利,但也隐含风险。这是由于,网络有着复杂及脆弱的特性,很易遭受侵害。若没能注重安全防范,将会拓展病毒的侵害面积,侵害隐私或减低了经济收益。针对于计算机安全,要探析现有的网络安全状态;在这种基础上,探析技术防范的可行措施。 In the information age, all industries are not divorced from the computer, network technology is integrated into a variety of existing areas. Computer networks add more convenience to daily life and production, but also imply risks. This is due to the complex and fragile nature of the network, which is vulnerable. Failure to focus on safety precautions will expand the area covered by the virus, compromise privacy or reduce economic returns. In view of the computer security, we must analyze the current state of network security; on this basis, we analyze the feasible measures of technology prevention.
