the proportion of companies’ computer security violated is 50%.in 1998,our country the public security cracked hacker case nearly 100,the purpose for economy of computer crime accounted for 70%.the cyber crime can make a business failure, leakage personal privacy, or the paralysis of a national economic, this is not alarmist. thus the network security becomes more and more important. there are various reasons of cyber crime.first,the computer user's security awareness. many computers do not install antivirus software and firewall, or can not guarantee the antivirus software updated daily, which give the computer criminals an opportunity. second,for illegal money online.
the implementation of network crimes is various, but from the quantitative analysis,for money, gain on the majority. third, the difficulties to get the evidence.the limited evidence of network crime left most also only have electromagnetic records, but there is no fingerprint or dna evidence, but such evidence is also very easy to destroy. fourth,the crackdown is not great on the computer in majority of countries. the laws of most countries do not make efforts on the prevention and control of network crimes,and the law is not sufficient to constitute a real threat to the internet crime.
in my opinion, the prevention of cyber crime we should first of all from the establishment of a sound outlook on life and values in the daily life, but not his.the network will occupy an increasingly important position in our future life, we should use the knowledge learning in school and life experience, to prevent and avoid being deceived. accumulating enough internet experience and prevention awareness of cyber crime, fully protect ourselves, away from the infringement of network crime.
