网络安全英文对话

网络安全应该从最基础的密码安全做起。因此共享文件应该设置密码，一旦不需要共享时立即关闭。一般情况下不要设置文件夹共享，以免成为居心叵测的人进入你的计算机的跳板。 如果确实需要共享文件夹，一定要将文件夹设为只读。通常共享设定“访问类型”不要选择“完全”选项，因为这一选项将导致只要能访问这一共享文件夹的人员都可以将所有内容进行修改或者删除。windows98/me的共享默认是“只读”的，其他机器不能写入；windows2000的共享默认是“可写”的，其他机器可以删除和写入文件，对用户安全构成威胁。不要将整个硬盘设定为共享。

我觉得应该有义务维护网络的环境，一旦发现违法行为，立即报告给网警，这样就可以从根本上杜绝网络犯罪的行为。

在日常生活或是工作学习中，大家都写过作文，肯定对各类作文都很熟悉吧，作文根据写作时限的不同可以分为限时作文和非限时作文。相信许多人会觉得作文很难写吧，以下是我精心整理的关于网络安全英语作文（精选10篇），欢迎阅读与收藏。

Recently, the news that U.S attack on Chinas 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.

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.

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.

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.

Artificial intelligence (ai) approach, someone worries about unemployment, some people in the future, someone in exploring business opportunities, also some people on the go. Before discussing these, maybe we should consider the outcome of human beings.

One might think about this topic too exaggeration,

The first recall what has happened in the history of mankind incredible things.

Incredible things, the need to please a few through to decide.

We please 1 was born in the 0 people born in the year of the (han dynasty) through 1600 A.D. (Ming dynasty), although spans 1600 years, but the man may be on the lives of people around you wont feel too exaggerated, just changed a few dynasty, still facing the loess back and busy day.

But if please 1 1600 British people through to 1850 in the UK, see the huge steel monsters on the water ran, this person may directly be frighten urine, this is never imagined that 250 years ago.

If again please 1 1850 through to 1980, I heard that a bomb can flatten a city, this person may be directly scared silly, 130 years ago the Nobel wasnt invented dynamite.

Then please 1 in 1980 people now? This person will be cry?

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.

In light of recent celebrity photo leaks from their cloud accounts, one major topic at this years China Internet Security Conference is cloud security. People have all heard the term "cloud" so many times, but what exactly is it?

The cloud refers to software and services that run on the Internet instead of your computer. Apple’s iCloud, for example, is a popular cloud service, as well as Dropbox and Google Drive.

The advantages of using the cloud? First, you can access your documents, photos and videos from anywhere. Your home, the office, on the train, as long as you’re connected to the Internet. You can also access your files from multiple devices like an iPhone, an iPad or a computer. And to make things even better, you don’t have to worry about backups, because most cloud services automatically saves your data for you.

The only problem is, when you a file from one device, make sure it’s d from the cloud too. Otherwise, a copy of it will be left in the cloud.

The progress of artificial intelligence. Speed is amazing, the future we will start to work side-by-side with artificial intelligence.

AlphaGo fire, five one hundred million people watching "man-machine war", in the end it depends on the technical advantage of big data and deep learning in a 4-1 winners posture tell people, to artificial intelligence is no longer just the scene in the movie, but in the real world there is another round of industrial revolution, however, this changes make many people feel scared, at that time all kinds of artificial intelligence threats to the human voice, according to the British science association entrusted network research firm YouGov, according to a survey of about 36% of people think that the rise of artificial intelligence technology will pose a threat to human long-term survival. People in all kinds of artificial intelligence can bring big Bob "unemployment" is deeply concerned about the discourse, but also in such a tough AlphaGo will be malicious use worrying on such issues.

The humn beings are stepping into the information society. The information industry develops very rapidly, so do the hackers, trick-playing teens, exploring children, fraudsters, and serious

wite-collar criminals. Thus, information security becomes an impending important issue.

In case of information breach, the victimsgovernment department, an organization, or an institution, or a company will inevitably suffer great or small loss. Government may be threated with national security. Companies may lose opportunities to develop new projects. And the publics and users will be damaged.

Then how to deal with this issueTechnology is only a partial solution to information security. Whats more important is that organizations and companies should promote the awareness on information security to its staff. However, since no system can ever be 100 percent secure, a prevention-only approach to information security mangaement is not enough. Companies and organizations should adopt a dual approach to information security management by combining prevention and detection techniques.

Along with the time development, accessing the net already turned the extremely universal matter. No matter is adult or the child, so long as mentioning the computer, all think of internet. But, accessing the internet is advantageous ,but also has shortcoming.

I knew very many people access the net, mainly is for playing games, which is very bad for the study. Therefore, some people believed, the elementary and middle school students lack the self-control.

But,there are many people approving to accessing internet, why? Because internet can provide to the people very helps. First, the network looks like a library, we can look up very many materials easily,and it is quicker than the speed of consulting books; Next, we may read a richer news on-line; In addition, accessing the net also has other functions, for example, E-mail, telephoning on the net and so on.

Actually, accessing the net has its profit and the shortcoming place. We use it to open to expand the field of vision, the study knowledge, but must certainly grasp the discretion.

As time goes on,going surfing on the Internet become more and more popular.It is a new phenomenon and sounds an alarm (for online security ).

Network security cover anti- virus , network security and hacker protection . Together with the technology of Access Control , redundant backup recovery and network security , it makes an allround security system . Many companies devote to the information security technology and product research and development , production and sales , providing advanced network security solutions . Firewall just is an effective measure of network security .

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.

ssl协议：什么是SSl安全协议？ SSL安全协议最初是由Netscape Communication公司设计开发的，又叫“安全套接层（Secure Sockets Layer）协议”，主要用于提高应用程序之间数据的安全系数。SSL协议的整个概念可以被总结为：一个保证任何安装了安全套接字的客户和服务器间事务安全的协议，它涉及所有TC/IP应用程序。 SSL安全协议主要提供三方面的服务： ·用户和服务器的合法性认证 认证用户和服务器的合法性，使得它们能够确信数据将被发送到正确的客户机和服务器上。客户机和服务器都是有各自的识别号，这些识别号由公开密钥进行编号，为了验证用户是否合法，安全套接层协议要求在握手交换数据时进行数字认证，以此来确保用户的合法性。 ·加密数据以隐藏被传送的数据 安全套接层协议所采用的加密技术既有对称密钥技术，也有公开密钥技术。在客户机与服务器进行数据交换之前，交换SSL初始握手信息，在SSL握手情息中采用了各种加密技术对其加密，以保证其机密性和数据的完整性，并且用数字证书进行鉴别，这样就可以防止非法用户进行破译。 ·保护数据的完整性 安全套接层协议采用Hash函数和机密共享的方法来提供信息的完整性服务，建立客户机与服务器之间的安全通道，使所有经过安全套接层协议处理的业务在传输过程中能全部完整准确无误地到达目的地。 安全套接层协议是一个保证计算机通信安全的协议，对通信对话过程进行安全保护，其实现过程主要经过如下几个阶段： （1）接通阶段：客户机通过网络向服务器打招呼，服务器回应； （2）密码交换阶段：客户机与服务器之间交换双方认可的密码，一般选用RSA密码算法，也有的选用Diffie-Hellmanf和Fortezza-KEA密码算法； （3）会谈密码阶段：客户机器与服务器间产生彼此交谈的会谈密码； （4）检验阶段：客户机检验服务器取得的密码； （5）客户认证阶段：服务器验证客户机的可信度； （6）结束阶段：客户机与服务器之间相互交换结束的信息。 当上述动作完成之后，两者间的资料传送就会加密，另外一方收到资料后，再将编码资料还原。即使盗窃者在网络上取得编码后的资料，如果没有原先编制的密码算法，也不能获得可读的有用资料。 发送时信息用对称密钥加密，对称密钥用非对称算法加密，再把两个包绑在一起传送过去。 接收的过程与发送正好相反，先打开有对称密钥的加密包，再用对称密钥解密。 在电子商务交易过程中，由于有银行参与，按照SSL协议，客户的购买信息首先发往商家，商家再将信息转发银行，银行验证客户信息的合法性后，通知商家付款成功，商家再通知客户购买成功，并将商品寄送客户。ssl代理就是支持这个协议的代理，只有这样的代理才能访问ssl的网站，比如hxxps:webmail.yale.eduTLS是传输层安全协议。 它实际上是SSL3.1，在1996年提交到IETF标准委员会替换控制的。即将发行。什么是PCT？从名称上可以看出，专利合作条约是专利领域的一项国际合作条约。自采用巴黎公约以来，它被认为是该领域进行国际合作最具有意义的进步标志。但是，它主要涉及专利申请的提交，检索及审查以及其中包括的技术信息的传播的合作性和合理性的一个条约。PCT不对“国际专利授权”：授予专利的任务和责任仍然只能由寻求专利保护的各个国家的专利局或行使其职权的机构掌握（指定局）。PCT并非与巴黎公约竞争，事实上是其补充。的确，它是在巴黎公约下只对巴黎公约成员国开放的一个特殊协议。

不要随意传播谣言，不要做网络喷子，更不要语言攻击，要共同维护网络的安全。

???好长啊！！！
