Internet-themed speech
Dear teachers and students:
Hello everyone!
As we all know, the network can provide us with rich knowledge and bring great convenience to our lives. For example, you can watch colorful content, enjoy information resources to the maximum, chat online and send emails conveniently &; In short, the network has many functions.
But students, do you know? The network is actually a "double-edged sword", and it also has great disadvantages. Improper use will cause great harm and even fall into the bottomless abyss of the network. You may know such a thing: A Xiang, a student in a primary school in this city, is addicted to online games, and began to commit violence against students. His revenge became more and more serious, his studies plummeted, and he finally suffered from schizophrenia.
Network can cultivate talents, and it can also lure people with poor ability to distinguish things into a bottomless pit. Nowadays, there are more and more bad information in the network, which poses a threat to the physical and mental health and safety of teenagers, and their self-control ability continues to decline, and their will and perseverance will be exhausted. Now students' ability to distinguish things is not too strong. If they are not careful, they may fall into a trap and ruin their future. What is even more frightening is the ambiguity of values and the dilution of moral values. Once the psychological defense line is broken by the impact of alienation, there will be a vicious incident of robbery, and some people will even take risks and embark on the criminal road of killing people.
Young people have their own colorful future life, and the future depends on whether individuals are on the right path. Students, when you swim freely in the network, please don't forget to adjust your mentality. You must remember that you are the master of the network, and don't let it hold your hands and feet and bind your thoughts. Don't let the trap of the network bury your colorful life all the way.
Students, I hope you can correctly use the double-edged sword of the network and serve yourself with the double-room "sharp blade" instead of cutting off your life with a bad blade!
That's the end of my speech, thank you!

Dear students:
Good afternoon, everyone. I am very happy to be here with you to discuss the speech on network security. The topic of my speech today is: Internet, a wonderful and dangerous world.
Network world, a wonderful world. But there is danger behind the wonderful. Have you ever thought that the theft of your QQ number may be caused by a virus, your system may be hijacked, and it may be the fault of hooligans; Your online bank was stolen, probably a phishing website. Your data is missing, don't say, it's probably a hacker. Everyone has always had a "special feeling" for hackers, thinking that all hackers are very powerful, otherwise how can they create viruses in computers.
Since there are hackers, there must be security personnel. What kind of "confrontation" is going on behind this online world? So today I will take you into the security field of this online world as a security officer.
My speech is divided into five parts: what is network security, the importance of network security, the current situation of network security, how to prevent network security and build a harmonious network.
First, let's take a look at what we mean by "network security". Network security refers to protecting the hardware, software and data in the network system from being destroyed, changed or leaked by accidents or malicious reasons, and the system runs continuously, reliably and normally without interrupting network services.
The specific meaning of network security is users (individuals, enterprises, etc. It is hoped that information involving personal privacy or business interests will be protected by confidentiality, integrity and authenticity when transmitted on the network.
At the same time, network security is a comprehensive subject involving computer science, network technology, communication technology, cryptography technology, information security technology, applied mathematics, number theory, information theory and other disciplines.
Alvin toffler Toler, a famous American futurist, once said, "Whoever has information and network will have the whole world." In the past, President Clinton of the United States also said, "The country that will control the world in the future will not rely on the army, but the country with leading information capabilities." This shows how important it is to master the network, and the importance of network security is also reflected.
The following are some data from the Federal Bureau of Investigation: According to the statistics of the Federal Bureau of Investigation, the economic loss caused by network security problems in the United States is as high as $7.5 billion every year. On the other hand, there is an average network computer intrusion every 20 seconds in the world.
In a large number of applications of Internet/Intranet, the security of Internet/Intranet is facing great challenges. In fact, resource sharing and security have always been a contradiction. In the open network environment, a large amount of information flows online, which provides the target for criminals to attack. Moreover, the diversity of computer network components, the wide distribution of terminals and the openness and interconnection of the network provide more convenience for it.
They use different means of attack to access or modify sensitive information flowing in the network, break into the computer system of users or government departments, peep, steal and tamper with data. Internet fraud, which is not limited by time, place and conditions, has stimulated the growth of crime to some extent because of its "low cost and high income". Criminal activities against computer information systems are increasing.
Let's take a look at the content of the third section "Network Security Status", which is also the problem that our network is facing now.
1, the problem of network security integrity is serious. With the development of the Internet, especially the rapid development of commercial applications, many lawless elements have extended their black hands to the Internet, resulting in frequent threats to network security and credit crisis in recent years. The white paper "Internet Status in China" shows that in 2009, the IP addresses of computers controlled outside China reached 1 10,000; There are 42,000 websites tampered with by hackers; The number of computers infected with "phreak" worm network virus reaches180,000 every month, accounting for about 30% of the number of infected hosts in the world. According to the information provided by the Ministry of Public Security, in the past five years, the number of viruses spread on the Internet in China has increased by more than 80% annually. Eight out of every 10 computers on the Internet are controlled by hackers, and the cases related to hacker attacks and sabotage activities accepted by public security organs have increased by 1 10% annually. Therefore, the network
The construction of network security environment has become an obstacle to the development of the Internet.
2. The awareness of information protection is weak, and the awareness of safety needs to be improved. This requires netizens to learn more about the network and enhance their awareness of self-protection of personal information online.
3. The development of information network security service industry is not mature enough. I won't explain this much, mainly related to the network security department.
Regarding network security, it can be said that malicious codes are rampant and the number of viruses is exploding. Please look at PPT, which is the data of Kabbah Lab in the past 15 (1992-2007). The data shows that in 2008 and 2009 alone, more than 30 million new malware were discovered. It shows that the network security situation is extremely severe.
Network security is a problem, of course, it must be solved, so how to prevent it? First of all, there will be no pie in the sky, don't be greedy and cheap, and don't be confused by some "winning traps". However, if you disclose a lot of personal information, the password setting should not be too simple. Don't use your birthday as a password, because it is not safe. As we all know, I won't say much about this. There are also many softwares downloaded to regular websites to avoid downloading files that bind Trojans. Don't be fooled by "fishing nets" in online shopping. Install anti-virus software and firewall on the computer, update security vulnerabilities in time, and avoid hacking.
Well, that's all for me. I wish everyone a safe and harmonious online life. Thank you for watching! ! !
Internet-themed speech
Hello, everyone, I am very happy to attend this speech. Life is so wonderful and splendid, but in my speech today, there is no great sadness between life and death, and there is no plain and gorgeous rhetoric. The topic of my speech is: Internet, a wonderful and dangerous world.
In 20xx, the password of csdn of China Software Development Alliance, the largest developer technology community in China, was leaked, and the passwords of over 654.38 billion users were leaked. Hackers have published some user information databases on the Internet, resulting in more than 6 million registered email accounts and their corresponding plaintext passwords being leaked. After this incident, security incidents such as Duowan.com, Renren.com and Sogou browser were exposed one after another.
Well, you haven't experienced the previous case personally. That is to say, everyone who has contacted and passed the title test knows that sometimes they will be called by the magazine to ask if they want to publish the title of the paper. Hehe, everyone knows this. It is obvious that your phone information has been leaked. How did it leak? Do I have to register online and pay for the title exam? Phone number is a mandatory option when registering, well, that's basically how it is leaked. Of course, it is very likely that other information has also been leaked.
Let's get down to business. The content of my speech is divided into four parts: what is network security, the importance of network security, the current situation of network security, how to prevent network security and build a harmonious network.
First of all, let's talk about what we mean by "network security". Network security refers to protecting the hardware, software and data in the network system from being destroyed, changed or leaked by accidents or malicious reasons, and the system runs continuously, reliably and normally without interrupting network services.
Network security is a comprehensive subject involving computer science, network technology, communication technology, cryptography technology, information security technology, applied mathematics, number theory, information theory and other disciplines. This is a difficult industry.
Someone once said, "whoever has the information will control the network, and whoever has the world." This sentence is not entirely correct. However, this has been well reflected in the stock market. This shows how important it is to master the network, and the importance of network security is also reflected. In a large number of network applications, security is facing great challenges. In fact, enjoying resources and security has always been a contradiction. In the open network environment, a large amount of information flows online, which provides the target for criminals to attack. They use different means of attack to access or modify sensitive information flowing in the network, break into the computer system of users or government departments, peep, steal and tamper with data. Internet fraud, which is not limited by time, place and conditions, has stimulated the growth of crime to some extent because of its "low cost and high income".
Let me talk about the current situation of network security in the big environment. First, the problem of integrity is serious. With the development of the Internet, especially the rapid development of commercial applications, many lawless elements have extended their black hands to the Internet, resulting in frequent threats to network security and credit crisis in recent years. The 20xx China Internet Security Report shows that in 20xx, the number of tampered websites in China was 16388, including government websites 1802. The user information databases of more than 50 China websites are circulated publicly on the Internet or sold through the underground black industrial chain, of which nearly 50 million pieces of data are confirmed as real information.
Second, the awareness of information protection is weak and the awareness of security needs to be improved. This requires netizens, or to know more about the basic knowledge of network security, and enhance the awareness of self-protection of personal information online.
Third, the development of information network security service industry is not mature enough. Professional services are all charged, and excellent personal network security protection products are rare. Events in the field of personal protection, such as 3q War and Kingsoft Internet Security Free, have been accompanied by the development of personal network security in China in recent years. It can only be said that domestic personal network security products have yet to be developed.
Regarding network security, it can be said that malicious codes are rampant, the number of viruses is exploding, and the network security situation is quite grim.
Network security is a problem, and it cannot be completely cured. As an enterprise, with the improvement of enterprise informatization, the investment in network security will also increase. Choosing an excellent network security service company in China is a general solution. As individual users, we have few means, so we have to strengthen our prevention. What can we do? First of all, there will be no pie in the sky, don't be greedy and cheap, don't be confused by some "winning traps", send the winning page, and don't click on the winning link casually. Don't disclose more personal information when registering online tools such as forums and mailboxes, because filling in information is tantamount to entrusting information work to management, and the password setting should not be too simple. Don't use your own birthday as a password, and it won't help to use your wife's birthday, hehe. And download any information to the regular website, so as to avoid the file being bound by trojans. Don't be fooled by "fishing nets" in online shopping. Install anti-virus software and firewall on the computer, update security vulnerabilities in time, and avoid hacker intrusion.
Network security is a big topic. Well, that's all for my little speech. I wish everyone a safe and harmonious online life.
Internet-themed speech
Dear teachers and students:
Hello everyone!
I will give you a speech today. Mdash& ampmdash A sharp double-edged sword.
As we all know, with the pace of the times and the update of science and technology, more and more new things are pouring into our world, including the Internet. Since the Internet entered China in the late 1990s, it has mushroomed and developed rapidly, and now it has spread all over urban and rural areas. As a new media means, Internet plays an important role in economic construction and people's activities, and also provides a broader world for teenagers to learn, communicate and entertain. But for adults, the Internet is a sharp "double-edged sword" and a rose with thorns. Many teenagers are addicted to the Internet and Internet cafes, lacking the awareness of self-protection and the ability to prevent dangers, which has done great harm to their study, health and thoughts.
Thus, the network can bring up talents, and it can also lead talents to the bottomless abyss. The following are the three hazards I have summarized:
1. The Internet poses a potential threat to the formation of young people's outlook on life, world outlook and values.
2. The Internet makes many teenagers addicted to the virtual world and divorced from reality, and also makes some teenagers neglect their studies. It is not unreasonable for many people to call the game "electronic heroin".
3. Bad information and cyber crimes on the Internet pose harm and threat to teenagers' physical and mental health and safety.
Many students have delayed their studies and given up their bright future. According to a survey, more than 80% online students are playing games, and about 15% are making friends and chatting. Few people really ask for information for learning.
Students who are addicted to the internet, let alone study in class, even save eating and sleeping. They are in a daze all day and can't stop. What can they get? I would like to appeal to those students who are still playing online games and immersed in illusory sweetness. When you are in full swing in body double, have you ever thought that your anxious parents are waiting for the news of your coming home? When you were intoxicated with the sword, did you think of the hard-working teacher who worked for you? When you chat with new netizens, have you ever thought that sincere words between classmates are true friendship? When you are addicted to those light gray online literature, have you ever thought that the real world is gradually leaving you? Students, get rid of the illusory world, the most precious thing &; When you click the mouse, time is irrevocably slipping away from the fingertips of the light keyboard. Students, how many years can a person's youth last? Don't be the head of a white boy, empty and sad. Throughout the ages, which successful great man did not cherish time like gold? For students, one second is a question, and one minute is a page.
In fact, there are many uncivilized phenomena on the network around us. You can see many uncivilized expressions on the post bar of our school. Why do these vulgar words appear in our middle school students' mouths and under the tapping of the keyboard? Maybe it has something to do with our living environment, but more often, we middle school students browse Wen Zi and pictures that are not conducive to the physical and mental development of minors on the Internet. ......
So how should we eliminate and reduce this phenomenon? First of all, we should learn to use the network correctly as a "double-edged sword", let it play a correct role, and don't let it hurt ourselves.
Young people look forward to a bright future, and the future is in our own hands. Don't let the big network entangle your hands and feet and bind your thoughts. Remember the sentence "Internet is a double-edged sword, beautiful but poisonous." We should make ourselves a smart person who uses the Internet correctly.
That's the end of my speech, thank you!

Dear leaders and colleagues,
Hello, everyone, I am very happy to attend this speech. Life is so wonderful and splendid, but in my speech today, there is no great sadness between life and death, and there is no plain and gorgeous rhetoric. The topic of my speech is: Internet, a wonderful and dangerous world.
The online world is a wonderful world. Qq, online shopping, online games and telecommuting have enriched and changed our lives, but there are dangers behind the excitement. Have you ever had your qq number stolen? Is this common? Online banking stolen? Lost documents, photos or other data? When reading a document on the computer, the mouse moved by itself. Your system was hijacked. Everyone has always had a "special affection" for hackers and viruses, thinking that all hackers are very powerful and all viruses are disastrous, right? Share two cases of network security with you.
20 1 1, the password of China Software Development Alliance (csdn), the largest developer technology community in China, was leaked, and the password of over 1 100 million users was leaked. Hackers have published some user information databases on the Internet, resulting in more than 6 million registered email accounts and their corresponding plaintext passwords being leaked. After this incident, security incidents such as Duowan.com, Renren.com and Sogou browser were exposed one after another.
Well, you haven't experienced the previous case personally. That is to say, everyone who has contacted and passed the title test knows that sometimes they will be called by the magazine to ask if they want to publish the title of the paper. Hehe, everyone knows this. It is obvious that your phone information has been leaked. How did it leak? Do I have to register online and pay for the title exam? Phone number is a mandatory option when registering, well, that's basically how it is leaked. Of course, it is very likely that other information has also been leaked.

First of all, let's talk about what we mean by "network security".

Network security is a comprehensive subject involving computer science, network technology, communication technology, cryptography technology, information security technology, applied mathematics, number theory, information theory and other disciplines. This is a difficult industry.

Internet fraud, which is not limited by time, place and conditions, has stimulated the growth of crime to some extent because of its "low cost and high income".
Our Baodi company has completed the construction of two existing systems, which have been networked, oa system and financial system. Needless to say, the importance of the financial system, oa system, the initial password has not been modified? The construction of oa system is generally the first step of enterprise informatization. With the increase of use time, oa system will accumulate a lot of company data in the future. The advantage of oa system is that all the data transmitted by everyone is on the local server, unlike using qq or other mail tools, the data is stored on the other server, which can ensure data security, especially after listing. So everyone must take care of the password. The company has now installed a firewall, which has protected the security of the company's two servers to some extent.
Let me talk about the current situation of network security in the big environment.
First, the problem of integrity is serious. With the development of the Internet, especially the rapid development of commercial applications, many lawless elements have extended their black hands to the Internet, resulting in frequent threats to network security and credit crisis in recent years.
