In the modern world, it is no doubt that Internet is playing an important role in our daily lives. It not only brings us information but makes our lives convrnient as well. However, the security of the Internet is always a hot potato that we have been facing with for years.

There is no denying that we are partly overwhelmed in the Internet life. Everything in our daily life can have relationship with Internet: Officers use it to type letters and make records; businessmen use it to keep contact with clients and do businesslteachers use it to make teaching plans; students use it to learn and study, and some peple use it for fun at home. It is clearly that most people like chatting with friends on the Internet.

My advice is when you chatting on the Internet, don't reveal your personal information, such as your real name, your phone number , your address and even your ID card number as well as your credit card numbers. Don't trust people on the Internet easily.

Some information on the Internet may not ture. You can't be too much carful when you read them and use them

Recently, the news that U.S attack on China's Internet is always exposed. And the question of how to stay online safely raises a lot of discussion in our country. As a result, in the era of rapid development of network, we must take measures to protect our security of privacy and property effectively.

最近的新聞都揭示了美國對中國網絡的攻擊。如何安全地上網在我國引起了大量的討論。結果是在網絡飛速發展的時代，我們必須要采取有效的措施來保護我們的隱私和財產安全。

From my perspective, in the first place, we should call attention to our personal information. Not only do we not offer them at random in some strange websites, but we need to distinguish right from wrong among the numerous websites. Furthermore, it is inevitable that some secure anti-virus soft wares can be installed. And it will make it possible for that network can run more steadily. In addition to doing some work by ourselves, the government needs to draw up some policies to preserve national cyber security. It involves probing for deeply rooted reasons, devising creative solutions, developing high-tech talents and strengthening the supervision.

從我的角度來看，首先，我們應該關注我們的個人信息。我們不僅不隨隨便便在一些奇怪的網站提供自己的信息，而且我們需要在眾多的網站之間明辨是非。此外，安裝一些安全的殺毒軟件是必須的。這使得網絡運行更加穩定。除了我們自己該做一些努力之外，還需要政府制定相關政策來保護國家網絡安全。這就涉及到探究深層次的原因，想出有創造性的解決方案，發展高新技術人才、加強監管。

Although scientists still cannot overcome the problem completely, they are studying a great deal about how to protect our national cyber security. However, consciousness of cyber security should not decline. Only in this way, we just enjoy the convenience brought by the network.

盡管科學家仍無法完全克服這個問題，但是他們正在研究大量關于如何保護我們國家網絡安全的辦法。然而，不應該放松網絡安全意識。只有這樣我們才能享受到網絡帶給我們的便利。

As the number of internet users continues to grow worldwide,internet safety is a growing concern for both children and adults. The internet safety, or online safety, is the knowledge of maximizing the users personal safety and security risks on private information and property associated with using the internet, and the self-protection from computer crime in general.

To begin with, we have to take the information security into consideration. As we all know, sensitive information such as personal information and identity, passwords are often associated with personal property (for example, bank accounts) and privacy and may present security concerns if leaked. Unauthorized access and usage of private information may result in consequence such as identity theft, as well as theft of property.

Whats more, the personal safety cannot be ignored. The growth of the internet gave rise to many important services accessible to anyone with a connection. One of these important services is digital communication. While this service allowed us to communicate with others through the internet, this also allowed the communication with malicious users. While malicious users often use the internet for personal gain, this may not be limited to financial/material gain. This is especially a concern to parents and children, as children are often targets of these malicious users.

How can we deal with the problems in the Internet safety? Actually, we have several preventions. First, keeping shared information at a minimum and safe passwords and PINs are useful. Moreover, wed better strengthen our Social network websites and security software.

Through the use of antivirus software, the user can automatically detect, prevent and remove computer viruses and various types of malware. Very often it is impossible for the user alone to identify infected files and software until it is too late, especially if the infected file or software is well disguised as legitimate files. Because of this, it is important that the user keeps antivirus software running on the computer whenever accessing the internet so that the user can filter and block infected files and firewalls.

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 users 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.

The advent of the Internet ushered in a new era of interpersonal communications and business operations. Undoubtedly, the Net are revolutionizing the daily lives of the people who have an access to it. The primary reason behind the Internet boom roots in its multifunction. It provides a vehicle for netizens to shop, search, publish blogs and browse WebPages.

A range of problems lurking behind the frenzy of Internet impressively stand out. A vast majority of Internet users mail boxes are saturated with junk mails, an issue which sparks strong criticism and generates the loss of corporate productivity. Its not alone. Porn websites lure a growing number of young peoples visits. False news via the e-mail, BBS and chat room increasingly poses a threat to the social prosperity and stability.

To crack down them, we should push for a more effectively tough law. We should join our forces to launch a nation-wide campaign, including imposing stiff penalties on spammers, shutting down or blocking the lewd sites and introducing a real-name registration system to curb fraudulent messages. We can fully believe that our combined efforts will reap rewards. A clean cyberspace will paint our lives more colorfully. An economically booming and technologically advanced global web will play a vital role in the national economic and cultural advancement.

網絡安全課程觀后感1

如今是“網羅”天下的時代。網絡，你是普羅米修斯，偷走了宙斯的火焰，點燃了閃電，照亮了人類黎明前的黑暗，讓拂曉的風聲在耳畔回蕩，世界因你而精彩。

網絡，你這個盜火者，你偷來了光明，卻也帶來了黑暗。還我隱私。這是一個張揚個性的時代，卻也是個缺乏隱私的時代。人們被大數據一點點地剖析，肢解，百無一漏地暴露在公眾視野之中。網絡，你偷走了人類的遮羞布，讓人成為赤__的“透明人”!前不久爆出的“棱鏡事件”，折射出信息安全的隱憂。高科技竊取我們的信息于無形之中，令人不戰而栗。

不久前，一位名叫琪琪的女孩，因一條微博，被人在網上挖掘個人信息并無情地嘲諷而不堪重負，最后含恨自殺。每一個人的心中都有秘密，正如每一個花蕾都包含著心事，強行剝開花瓣必定會使花蕾凋亡，無情揭開個人隱私必將導致人間慘劇發生。還我距離。生活在網絡時代，縱使相隔千里，也可以面對面交談，于是人與人之間的距離近了，而心的距離卻遠了。我曾無數次地回想起那個“烽火連三月，家書抵萬金”的時代，雖然戰亂不斷，天各一方，卻能“千里共嬋娟”，共話相思意。然而，在這個霓虹燈點綴了夜空，萬家燈火齊明的大數據時代，手機卻反客為主，儼然成了聚會的主角。當“一起來玩手機，順便吃個飯”成為年輕人的口頭禪時，我們不禁感嘆人情變了：沒有了朱自清的“咫尺天涯，叫我如何奈得”的感慨，卻有加拿大女作家的“世界上最遠的距離，不是你在天涯，我在海角，而是我在你面前，你卻不知道我想你”的無奈。網絡，你偷走了距離，讓心的故鄉何處尋覓?還我詩情畫意的生活。怎能不向往、向往川端康成凌晨四點半看海棠花未眠，向往瓦爾登湖畔盧梭的小木屋，向往王爾德在陰溝里仰望星空，向往倉央嘉措通透風情踏雪尋梅。反觀當下，沒了詩情沒了畫意，處處是屏奴。當點贊、刷微博成了生活的主旋律，我們真正的生活又去了哪兒?

網絡，當我再一次把你放在聚光燈下，細細端詳，終于窺見了你的真容。你原本只是高科技時代的一個工具，無關好與壞，功與過。合理利用，你可以使人們玩弄世界于股掌，傳遞信息，播散知識，造福人類。掌控不當，你也可以剝奪隱私，傳播謠言，色情暴力、高科技犯罪把人們推向萬劫不復的深淵。

利弊，黑白，兩極之間本無界定，然而物極必反，就看你如何掌控。網絡，可以送你上天堂，也可以帶你下地獄。如何讓高科技為人類謀福祉，全在人類的智慧。

網絡安全課程觀后感2

當今是網絡的時代，網絡給人們帶來便利是也給人們帶來了危害，網路已經成為人們生活的重要主成部分，成為人們生活，*** ，交友，學習等主要的 渠道 。

網路危害的形式也比較多，網路危害的對象主要是未成年人，他們的控制力較差，加上家長和學校管教不嚴，導致許慘案接連發生。

網絡危害的主要方式有：不良信息、暴力游戲的渲染、色情、等等。

第二十六次中國網絡發展狀況統計 報告 表明，截至20_年_月我國網絡用戶有4.2億人，有手機用戶有2.7億人，其中未成年認識主要成分，占百分之六十以上，大多數人能夠適度，合理的安排時間，但也有一部分人成天無節制的使用網絡。影響了正常的生活習慣。

網絡也許要安全，你可能有過這樣的遭遇，你從網絡上下載一些東西不能使用，反而還不能刪除，這就莫名奇妙的浪費了時間和精力。你的一些秘密就因下載了這而被別人竊取啦。

網絡安全也是不可忽視的問題!現在是網絡時代!這不僅要靠監察部門。還要靠我們大家來維護網絡。給未成年創造一個安全的上網環境。

網絡安全課程觀后感3

當今，伴隨著信息科技的迅速發展，社會各階層掀起了電腦網絡的熱潮，網絡這個新興科技時代已經家喻戶曉，人們可以輕而易舉地利用網絡來獲取自己所需的信息了。

世界的每一個角落都有中國人的足跡，雖然遠隔千山萬水，但和親人，仍能進行最“親密”的接觸，這都是因為有了網絡的關系，只要有聊天軟件，無論天涯海角，隨時隨地都能進行面對面的“親密接觸了”。

古人說：“秀才不出門，便知天下事”，但如今的人們，不是每個人都是秀才，卻更勝似秀才，這些都是因為互聯網上的很多的網站，各種欄目的網站應有盡有，人們可以足不出戶便知天大事，可以不行萬里路，讀萬卷書，便可以了解風土人情和周圍環境了。

當然，有得必有失，互聯網和地球一樣有陽光明媚的一面，也有陰暗的一面，錯誤的信息供我們誤入歧途，_信息使我們變得不文明，和懷有不良動機的“知心朋友”。某校一女生在網上聊天結識了一位網友，那人自稱是“喜歡真實的姐姐”，二人交往時間不久就成了“知心朋友”。該女生因為輕信這位網上“好友”，獨自與他見面，見面才知道這位姐姐是成年男人，該女生知道上當后，后悔莫及，那人強行施暴，使該女生的心靈受到嚴重傷害。從這個例子可以看出，害人之心不可有，防人之心不可無，不能輕信網絡中虛幻的東西，否則會鑄成大錯。

說到上網與身心健康，可能對于缺少自我保護意識的青少年認為，上網，不過是學習，交流，與自己的身心并沒有關系，說起來有點牛頭對馬嘴。實際這兩者這間有著密切的關系!一個人如果長時間的注視電腦，眼睛會過度疲勞，表現為眼睛脹痛，流淚不止，嚴重的會引起頭前等癥狀，所以，我們應合理安排時間，健康上網，我們就可以得到了上網的真正樂趣。

互聯網又像個大禮堂，每個人都有尊重與被尊重的權利，無論熟人還是陌生人，都要時刻講究禮貌。

讓我們一起來杜絕不良網絡站，在積極健康的綠色網絡中，快樂的成長起來!

網絡安全課程觀后感4

不可否認，網絡是把雙刃劍。在當今社會，網絡安全不得不引起了很多人的重視。網絡對當今社會的影響還是很大的。

我們的生活跟隨社會的發展越來越美好，特別在農村表現更為明顯，有便利的交通及先進的網絡通訊工具迅速發展及廣泛應用。比如電腦就闖入到了千家萬戶，它我們生活中，存在著許許多多的善美，雖然方便，同時它也是一個惡魔?？茨阍鯓訉Υ?

網絡的善美非常之多，比如說上網聊天，拉近朋友之間的距離，網上購物很方便，上網查閱資料，一點擊，就會有許多答案從屏幕上出來，讓你查也查不完，看也看不盡，可以看看新聞，了解國家大事，也可以聽聽音樂，使我們的心情舒暢，這樣可以從網上學到許多東西，而且還可以從網上吸取許多知識，讓你的學習不斷地進步，讓你的成績不斷提升。豐富我們的生活。

另外，由于我們青少年正處于成長時期，閱歷少， 經驗 不足，在網絡這個繽繁世界游歷時，一定要注意樹立自我保護意識，在自己的頭腦里建立起“安全防火墻”，以抵御不良信息對我們的影響。標明限制信息的，如果自己處在限制區域內，一定不能進入。

網絡的世界是五彩繽紛的，我們要善于使用網絡，要正確使用網絡，學會拒絕網絡中的種種不良誘惑，我們應做到“文明上網，上文明網”，讓網絡在我們的生活中，幫助我們吧!

網絡安全課程觀后感5

對于網絡安全，相對于我來說，在未接觸這門課程之前，可以說是一個漏洞，一片空白，網絡安全的意識也是很是淡薄。之前也是聽說過網絡攻擊，盜取情報，竊取密碼，查看個人隱私等一些迫害網絡安全秩序的不法行為，這也讓我對網絡產生一種懼怕感。這次有幸接觸網絡安全這門課程，也讓我對于網絡安全有了新的認識，更多的了解，也讓我從中受益很多。

網絡安全從其本質上講就是網絡上的信息安全。指網絡系統硬件、軟件及其系統中數據的安全。網絡信息的傳輸、存儲、處理和使用都要求處于安全狀態可見。網絡安全至少應包括靜態安全和動態安全兩種靜態安全是指信息在沒有傳輸和處理的狀態下信息內容的秘密性、完整性和真實性：動態安全是指信息在傳輸過程中不被篡改、竊取、遺失和破壞。實際上計算機網絡安全的具體含義會隨著使用者的變化而變化，使用者不同，對網絡安全的認識和要求也就不同。

例如從普通使用者的角度來說，可能僅僅希望個人隱私或機密信息在網絡上傳輸時受到保護，避免被竊聽、篡改和偽造;而網絡提供商除了關心這些網絡信息安全外，還要考慮如何應付突發的自然災害、軍事打擊等對網絡硬件的破壞，以及在網絡出現異常時如何恢復網絡通信，保持網絡通信的連續性。網絡安全既有技術方面的問題，也有管理方面的問題，兩方 面相 互補充，缺一不可。隨著互聯網的大規模普及和應用，網絡安全問題也隨之呈現在我們面前。病毒滲透、系統漏洞和黑客攻擊等威脅層出不窮，已經嚴重地影響到網絡的正常運行。網絡規模的日益龐大，給網絡安全防范人員提出了更加嚴峻的挑戰。

人力、物力和財力的有限性決定了不可能完全地依賴手工方式進行安全分析防范所以如何采取更加快捷方便而且行之有效的 方法 進行攻擊分析已經成為網絡安全的重要課題。隨著計算機技術的飛速發展，信息網絡已經成為社會發展的重要保證。有很多是敏感信息，甚至是國家機密。所以難免會吸引來自世界各地的各種人為攻擊(例如信息泄漏、信息竊取、數據篡改、數據刪添、計算機病毒等)。同時，網絡實體還要經受諸如水災、火災、地震、電磁輻射等方面的考驗。計算機犯罪案件也急劇上升，計算機犯罪已經成為普遍的國際性問題。據美國聯邦調查局的報告，計算機犯罪是商業犯罪中最大的犯罪類型之一。

計算機網絡安全存在的威脅嚴重的威脅。由于計算機網絡計算機網絡組成形式多樣性、終端分布廣和網絡的開放性、互聯性等特征，致使網絡容易受到來自黑客、惡意軟件和 其它 種種攻擊。

What is a network security

Network security is that the network system hardware, software and system data will be protected from accidental or malicious destruction and the reasons for the change, leaks, the system for normal operation and reliable network services without disruption.

1. Network security overview

With the rapid development of computer technology in the computer processing business from the math based on the single, document processing, based on the simple connection of the internal network of internal business processes, such as development of office automation based on complex internal network (Intranet) , outside the enterprise network (Extranet), the Global Internet (Internet), enterprise-class computer processing system and worldwide sharing of information and business processes. Improve handling capacity in the system at the same time, the system's connectivity is also constantly enhanced. But in the ability to connect information, the effectiveness of the circulation At the same time, based on the network connection security issues is increasingly conspicuous, and the overall network security is manifested in the following aspects: the physical network security, network topology security, network security, application system security and network management security.

So computer security issues, it should be like every household fire security issues, the Government should do. Not even think of your own will be targeted, there have been threats on the event, often unprepared, causing a great loss.

2. Physical safety analysis

Network security is the physical security of the entire network system premise. In the campus network in the construction of the network system is weak due to works of low pressure. Therefore, in the network engineering design and construction, the priority must be given to the protection and network equipment without electricity, fire and lightning against Considering cabling system and lighting wires, power lines, communication lines, heating ducts and cold air ducts the distance between Considering cabling system and insulation lines, naked lines and the ground and welding safety system must build mine, mine system will not only consider the mine buildings, it must also consider computers and other equipment Weak Pressure mine. Overall, the risk of physical security mainly, earthquakes, floods, fires and other environmental incidents; power failure; human operational error or mistake; equipment stolen, destroyed; electromagnetic interference; line intercepted; high availability hardware; Dual more redundant Balance design; room environment and alarm systems, security awareness, and so on, therefore, is to try to avoid the physical network security risks.

3. Network structure, the safety analysis

Network topology design have a direct impact on the security of network systems. If the internal and external communications network, the machine internal network security will be at risk, but also the same impact on the network of many other systems. Spread through the Internet will affect connected to the Internet / Intrant other network spreads, it could also involve legal, financial and other security-sensitive areas. Therefore, we design it is necessary to open server (WEB, DNS, EMAIL etc.), and other internal business network and the necessary network segregation and avoid network structure information compromised; at the same time, external network service requests to be filtered only allow normal communication of data packets arrive at their corresponding console, the other at the request of services in the mainframe should be rejected before.

4. System, the safety analysis

The so-called system of security refers to the entire network operating system and network hardware platform is reliable and trustworthy. At present I am afraid there is no absolute security can choose the operating system, whether it is the Microsfot Windows NT or any other commercial UNIX operating system, the developers will have its Back-Door. Therefore, we can reach the following conclusion: not completely secure operating system. Different users from different aspects of their network for detailed analysis, choose the highest possible safety of the operating system. So not only as reliable as possible to choose the operating system and hardware platform and operating system security configuration. Moreover, the need to strengthen login authentication process (especially in the mainframe before the arrival of authentication servers), ensuring that users of legitimacy should be followed strictly limit the operation log authority, the operation will be performed in the restricted within the scope of the smallest.

5. Application system, the safety analysis

Application of the safety system with the specific application, which covers a wide range. Application of the safety system is dynamic and constantly changing. Application security also involves the security of information, which includes many aspects.

-- Application System security is dynamic and constantly changing.

Application security involves many aspects, the current most widely used on the Internet E-mail system, its solutions are sendmail, Netscape Messaging Server, Software.Com Post.Office, Lotus Notes, Exchange Server, and so no less than two SUN CIMS more than 10 kinds. LDAP means involving its security, DES, RSA, and other methods. Application development system is constantly and application types is growing. In the application of the security of the system, the main consideration, as far as possible establishment of a safe system platform, but also through professional security tools to find loopholes to mend loopholes, and improve the security of the system.

-- Application related to the security of information and data security.

Information related to the security of confidential information leaks, unauthorized access, destruction of information integrity, counterfeiting, such as the availability of the system. In some network system, involving a lot of confidential information, some important information was stolen or damaged, and its economic and social implications and political implications will be very serious. Therefore, the computer user authentication must be carried out, important information communications must empower, transmission must be encrypted. Using multi-level access control, and power and control methods to achieve data security protection; use encryption technology to ensure that data transmission over the Internet of information (including passwords and account managers, upload information, etc.) confidentiality, and integrity.

6. Manage security risk analysis

Network management is the most important thing in the part of security. Select the right unknown, security management system is not perfect and the lack of operational management and so may cause security risks. When a network attack, or by some other network security threats (such as internal personnel operated in violation of regulations, etc.), can not be carried out real-time detection, monitoring, reporting and early warning. At the same time, when the accident occurred, were unable to provide the hacker attacks based on detection and tracking clues that the lack of network control and auditable. This requires us to visit the site to record levels of more timely discovery of illegal act of aggression.

Establish a brand-new network security mechanisms, we must thoroughly understand the network and can provide a direct solution, therefore, the most feasible approach is to develop a sound management system and strict management. Protection of the safe operation of the network, making it a good security, scalability and easy management of the information network will become a top priority. Once the security risks become a reality, caused by the loss of the entire network are incalculable. Therefore, the building of network security is the process of building the campus network an important part.

7. Network security

-- Physical measures: for example, the protection of key network equipment (such as switches, the large-scale computer, etc.), strict network security rules and regulations, to take radiation protection, fire prevention and installation of uninterruptible power supply (UPS), and other measures.

-- Access Control: the user access to network resources for the strict certification authority and control. For example, user authentication, password encryption, update and identification, with the user's files and directories, access permissions, and network equipment configuration control authority, and so on.

-- Data encryption: encryption to protect data security is an important means. Encryption is the role of information security can not be intercepted understand its meaning.

Prevent computer network virus, and install network anti-virus system.

-- Other measures: Other measures include information filtering, fault tolerance, data mirroring, data backup and auditing. In recent years, centering on the issue of network security put forward a number of solutions, such as data encryption and firewall technology. Data encryption is on the network transmission of data encryption, decryption arrive later reverted to the original data to prevent unauthorized users intercepted after the theft of information. Firewall technology is adopted for the network isolation and restricted access methods to control network access, thereby protecting network resources. Other safety technologies include key management, digital signature, authentication, smart card technology and access control, and so on.

Network security is one of computer science, network technology, communications technology, encryption technology, information security technology, applied mathematics, number theory, information theory and other disciplines comprehensive discipline.

Network security is that the network system hardware, software and system data will be protected from accidental or malicious destruction and the reasons for the change, leaks, the system for normal operation and reliable network services without disruption.

Network security is its essence, speaking on the network information security. Broadly speaking, any information relating to the network the confidentiality, integrity, availability, authenticity and controllability of the relevant technology and theory are network security research field.

Network Security Council with the specific meaning of "perspective" varies. For example: users (individuals, businesses, etc.) point of view, they want to personal privacy or commercial interests of the information in the transmission network is subject to confidentiality, integrity and authenticity of protection, avoid other people or opponent use of wire-tapping, impersonation, tampering with, or deny, such as means of violating the interests of users and implicit, the Q and destruction.

From the perspective of the operation of the network and managers say they want information on the local network access, read and write operations such as protection and control, to avoid the "trapdoor", viruses, unauthorized access, denial of service and network resources illegal occupation and illegal control , and other threats, repression and defense network hackers.

On the security sector, they hope to illegal, harmful or involve state secrets filter the information and blockades, to avoid leaking confidential information to avoid harm to the community, the country resulting in tremendous losses.

From a social perspective, education and ideology, unhealthy content on the network, will be the stability of society and human development are causing obstruction, must be controlled.

2 and enhance the network security awareness delay

With the rapid development of computer technology, information networks has become an important guarantee for social development. Information related to national network of government, military, culture, education, and other areas. Including storage, transmission and processing of information is important to many of the government's macroeconomic control policy, commercial economic information, bank funds transfers, stocks and shares, energy resources data, and scientific research data, and other important information. Many of sensitive information, or even a state secret. So will inevitably attract from all over the world manmade attacks (such as information leakage, theft, tampering with data, data cut-tim, computer viruses, etc.). At the same time, network entities to withstand such as floods, fires, earthquakes, electromagnetic radiation and other aspects of the test.

In recent years, computer crimes have increased dramatically computer crime has become a widespread international problem. According to the FBI report, computer crime is a commercial crime one of the largest types of crime, and the average amount of each crime for 45,000 US dollars, the annual computer crime caused economic losses as high as 50 billion dollars.

Most computer crime is transient, WAN, professional, temporal and spatial separation characteri
