我們生活在一個信息科技發達的時代，網絡的應用已經逐漸取代電話和電視，給我們的生活帶來了許多的方便，已然成為我們的生活中不可或缺的一部分。然而隨著網絡科技的逐步發展，網絡的應用逐漸普及，以網絡為載體的犯罪行為也逐漸出現。企業電腦安全受到侵犯的比例為50%，1998年我國公安部破獲黑客案件近百起，其中以經濟為目的的計算機犯罪占70%，計算機犯罪能使一個企業倒閉，個人隱私的泄露，或是一個國家經濟的癱瘓，這些絕非危言聳聽。因而網絡安全的維護變的越來越重要。
計算機網絡犯罪的原因多種多樣。（一）計算機使用者安全意識淡薄。很多計算機并沒有安裝殺毒軟件或防火墻，或者不能保證殺毒軟件的每天更新，這就給計算機犯罪人員以可乘之機。（二）網上貪圖非法錢財。實施網絡犯罪的動機多種多樣，但從數量上分析，貪圖錢財、牟取私利占大多數。（三）取證困難，證據有限網絡犯罪留下的最多也僅有電磁紀錄，而不會有指紋、DNA等證據，而且這些證據十分容易毀滅。（四）多數國家對計算機打擊力度不大。大多數國家的法律對防治網絡犯罪沒有做大的努力，其現有的法律不足以對互聯網犯罪構成真正的威脅。
在我看來，預防網絡犯罪我們首先應該從在日常生活中建立一個健全的人生觀價值觀開始，而不是隨性而為。網絡在我們日后的生活肯定會占據越來越重要的位置，我們應該應用在學校學習的知識和生活中的經驗，積極地預防和避免上當受騙。在平時積攢足夠的網絡使用經驗和網絡犯罪防范意識，充分的保護自己，遠離網絡犯罪的侵犯。
We live in a technology era, the network has gradually replaced the telephone and television, brought a lot of convenience to our lives, has become an indispensable part of our life. However, with the development of network technology, the network application becomes more and more popular and the crime base on the network also come gradually. 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.
