Speech on promoting network security

In view of the network security vulnerabilities, various new risks created by hackers will appear constantly. These risks are caused by many factors, which are closely related to the network system structure and system application. You may wish to take a look at my speech on promoting network security, hoping to bring you help!

The Internet has brought a lot of convenience to our life. It is not limited by space and time. However, the network is not a pure world, and online pornography is rampant, and many criminal activities are carried out with the help of the network. This warns the world that although the Internet world is a wonderful virtual world, it is also a place that must be doubly guarded. Thousands of parents may not be aware of the dangers on the Internet. The online world is full of traps, full of people with ulterior motives to lead children astray; Children's pure hearts are easily polluted, but children and parents often don't realize it. So, how to make children face the invisible world of the Internet? As parents, we should try our best to communicate with our children to eliminate the harm brought by the online world.

Harm of surfing the Internet:

First, it poses a potential threat to the formation of students' outlook on life, values and world outlook. Internet is an endless "net" with rich and complex contents. Students frequently come into contact with the propaganda and cultural ideas of western countries on the Internet, which makes the traditional cultural ideas of China precipitated in their minds conflict with the mainstream ideology of our country, which makes students' values tilt and even blindly follow the West. In the long run, it will exert a subtle influence on Chinese students' outlook on life and ideology, which is obviously a huge potential threat to the political stability of the country.

Second, the Internet has made many students indulge in the virtual world of the network, divorced from reality, and also made some students neglect their study. Different from the real social life, students face a virtual world online, which not only meets the needs of students to possess all kinds of information as soon as possible, but also leaves a broad imagination space for interpersonal communication without having to bear the pressure and responsibility in real life. These characteristics of the virtual world make many students prefer to indulge in the illusory environment all day rather than face the real life. However, unlimited internet access will have a great impact on daily study and life, and even seriously ignore learning.

3. Bad information and cyber crimes on the Internet pose harm and threat to students' physical and mental health and safety. At present, the harm of the network to students is mainly concentrated in two points. First, some people commit crimes such as fraud or sexual assault; On the other hand, it is the harm of yellow garbage to students. According to the investigation of relevant experts, 47% of non-academic information on the Internet is related to pornography, and the Internet makes pornographic content easier to spread. According to incomplete statistics, although 60% of students are inadvertently exposed to online pornographic information, students with weak self-control are often out of curiosity or impulse, and will further look for similar information, thus falling into it. The survey also shows that more than 90% of students who have been exposed to online pornography have sexual crimes or motives.

The psychological characteristics of online game addicts are: more and more times to enter internet cafes, from which they can get certain psychological satisfaction; When you don't play online games, you will have withdrawal symptoms, such as depression, irritability and emotional irritability; The actual time to play games in the online game room is longer than expected, and I have considered stopping or reducing my access to the online game room, but I can't control myself; In order to enter the online game room, you can give up studying and other life activities; Have a strong desire for self-expression.

situation

1 Taizhou, Jiangsu 12-year-old boy, who was addicted to online games, left home for two months.

2. A 14-year-old middle school student in Lincheng Town, Lingao County, Hainan Province, played computer games for a long time without eating or drinking during the May Day holiday and died suddenly at his computer desk.

Cai Ba, the youngest hacker in China's history, spent six days and six nights breaking into Tencent's internal system, but was immediately detained by the Public Security Bureau.

A sophomore with 2 1 has been playing games in the internet bar for dozens of hours. When he was about to leave the Internet cafe and go back to school, he suddenly felt a headache, his eyes went black, and then he fell to the ground and fell into a coma. After admission, he was diagnosed as "retinal fatigue and hypoglycemia caused by excessive Internet access".

5. In May 2004, a senior student in a university in Jiangxi Province became addicted to the Internet, causing paranoia, and then two people died and five people were seriously injured.

The harm of Internet addiction to students is mainly reflected in the following points:

(1) Harm to health. Students are in a long-term healthy period. Sitting in front of the computer for a long time without proper exercise will lead to their poor eyesight and mental fatigue, which will seriously affect their growth and development. Classmates who often surf the internet will cause left brain dysplasia, decreased language expression ability and even confusion.

(2) Personality alienation affects social communication. Excessive use of the internet will lead to an increase in loneliness and depression, and will lead to a decrease in social participation and psychological well-being. (3) Causing role confusion and inducing criminal behavior: Online games give students opportunities to play various roles, but at the same time, they also bury hidden dangers for students' role confusion. Most online games are mainly composed of "attack, fighting and competition". Playing racing, slashing, blasting, gunfight and other games for a long time, the hot and exciting content can easily make players lose their moral cognition and lose themselves, so they can't rationally exercise their roles in the real society. They mistakenly believe that this way of achieving their goals by hurting others is reasonable. Once this wrong view is formed, they will cheat, steal and even violence others by any means. (4) obstructing the completion of studies. Excessive use of the Internet encroaches on study time, weakens study interest, destroys study habits and reduces study efficiency, thus affecting academic performance.

(5) Dilute moral constraints and abuse and attack on the Internet. The students' minds are not yet mature. You can't be "cautious and independent" when surfing the internet, and you can't keep a clear head when facing the network. Say whatever you want online, regardless of the consequences. Many students regard the internet as a window to vent their dissatisfaction, abuse it at will, and dare to say anything uncivilized without self-discipline.

Network is not only a hot topic in recent years, but also an indispensable tool for people to exchange information, which has made great contributions to our modern culture and technology. 2 1 century people must know computers, or they will be illiterate in modern science and technology. Everything has advantages and disadvantages, which is also the inevitable relationship of things. As a result, various problems have arisen, such as online games, pornographic networks and a series of web pages, which have harmed many young students!

How to overcome the negative influence of network on the healthy growth of teenagers? Due to the negative influence of the Internet, we must not "give up eating because of choking". We should try our best to minimize the negative impact through various means and methods. Schools and families, including Internet cafes, should strengthen the guidance and supervision of students' use of the Internet. Relevant departments should strengthen the monitoring and supervision of the internet, promote the rule of law, enrich students' off-network topic activities as much as possible, and let them feel the beauty of the outside world without indulging in the internet.

In a word, this is a long-term and complicated work, which needs the unremitting efforts and cooperation of the whole society and family. Strengthen network legislation, purify the network environment, deepen education reform, purify social atmosphere, let the whole society act and give children a healthy environment for growth.

Speech 2 on Network Security 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 done by 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! ! !

Hello, everyone, I am very happy to attend this speech. Life is so wonderful and splendid, but there is no great sadness between life and death in my speech today, and there is no plain and gorgeous rhetoric. My topic 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's 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 xx website 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 the information is tantamount to entrusting the confidentiality of the information to the management, and the password setting should not be too simple. Don't use your birthday as a password, which is not good for 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 hacking.

Network security is a big topic. Well, that's all for my little speech. I wish everyone a safe and harmonious online life.
