Today I want to talk about something really important - staying safe from the bad guys on the internet. The internet is awesome and lets us learn, play games, watch videos, and talk to our friends. But there are also some meanies out there who try to steal info, break into accounts, and cause trouble online. They're called cybercriminals.College students have to be extra careful because they often have important stuff on their laptops and phones like papers for class, bank info, emails, and private pics. The bad guys would just love to get their hands on that kind of stuff! That's why it's so crucial for college kids to know how to fight back against cybercrime.Here are some tips that can help keep you safe online:Use Strong Password ProtectionThis is like your first line of defense against the hackers. Using weak passwords or the same password across multiple accounts is just asking for trouble. Instead, you want passwords that are really long and complex, with uppercase, lowercase,numbers, and symbols all mixed up. That makes them super hard to crack.It's also best to use a different unique password for each important account you have. That way if one does get hacked, your other accounts are still safe. Writing them all down in a secret notebook can help you remember them.Install Anti-Virus/Anti-MalwareViruses, malware, and other nasty bugs are how a lot of cybercriminals try to infiltrate your devices. But you can stop them by installing anti-virus and anti-malware software. This will scan your computer and zap any threats before they can cause damage.Just be sure to keep the anti-virus updated so it can detect the latest malware strains that pop up. Let it run frequent scans to catch anything fishy. Most colleges provide anti-virus for students, but you can also get it on your own.Use Two-Factor AuthenticationThis adds an extra layer of security on top of your password. Two-factor authentication requires a second step to verify it's really you trying to login, like entering a code sent to your phone.That way, even if a hacker does get your password, they still can't access your account without that second verification step.It takes a tiny bit more work, but two-factor auth will lockout hackers and give you great peace of mind. Be sure to enable it everywhere you can - email, banking, social media, and more.Be Careful What You ClickA lot of cyberattacks happen when you accidentally click on something malicious like a weird link or email attachment. The bad guys are super tricky and will try to disguise these as something legit to lure you in.So be very cautious about any links or attachments you get, even if they seem to come from a friend or company you know. Verify they're safe before clicking. When in doubt, call your friend or the company to check if they really sent you that file. It's better to be safe than sorry!Watch What You ShareWe all love posting fun pics and updates for our friends online. But you have to be smart about what kind of personal info you share, because hackers love to piece things together to steal identities, open credit cards, or commit other crimes in your name.Avoid putting stuff like your birth date, address, full name and location, or passwords/PINs anywhere public. Be cautious aboutsharing private pics or secrets too. The internet is forever, so think twice before posting something you may regret later!By following these cybersecurity tips, you can help fend off the sneaky criminal hackers and enjoy the internet safely during your college years. Stay alert, use protection, and don't make it easy for those bad guys to get into your stuff. Power to the good folks online! Let me know if you have any other questions!篇6How to Fight and Stop Bad Computer CrimesHi there! My name is Timmy and I'm going to tell you all about bad computer crimes that happen on the internet. The grown-ups call them "cyber crimes." A lot of students in university have to learn about this stuff because it's really important.Cyber crimes are any crimes that happen by using a computer or the internet. They can be really bad and hurt a lot of people! Some examples are hackers breaking into systems, viruses that mess up your files, and people trying to steal your private information like passwords. There's also cyber bullieswho are mean online, and predators who try to trick kids. Some cyber criminals even help terrorists! It's a huge problem these days.But don't worry, there are ways to fight back against the bad guys! University students are taught all about cyber security to help protect themselves and others. I'll explain some of the biggest cyber threats and how to stay safe.One of the biggest threats is malware, which means malicious software nasties like viruses and ransomware. Viruses can corrupt your files and make your computer go crazy! Ransomware locks you out of your own files until you pay money to the cyber crooks. It's like they kidnap your data! The best way to stop malware is by using good anti-virus software that catches it before it infects your system.Phishing is another big problem where sneaky people try to trick you into giving away your passwords or payment info. They might send fake emails pretending to be your bank, or make copycat websites to steal your login details. You have to be really careful about any links you click or info you enter online. Always double check that websites are legit before logging in!Hacking is when bad guys try to break into computer systems that don't belong to them. Some do it for fun, otherswant to cause trouble, and some are after secret data they can sell. Hackers use clever programs to guess passwords or find security holes. That's why it's super important to have strong passcodes and keep software updated to fix any vulnerabilities.Speaking of passwords, you gotta make them really hard to guess but still memorable for you. Don't use easy words, birthdays, or your name because those are too easy to figure out. Instead, use random combos of letters, numbers, and symbols. And definitely don't use the same password everywhere! If it gets hacked once, the crooks have the key to all your accounts.Anyway, those are some of the biggest cyber crime dangers out there. Now I'll talk about some of the best ways university students can help fight back and keep the internet safe:First off, get good anti-virus protection and keep it updated! Let it scan your system regularly to catch any nasties. And be crazy careful about what programs you download or install, because some can hide malware inside.Next, watch out for any phishy emails or websites asking for private info. Never click sketchy links or enter your login unless you're 100% sure it's the real website. When in doubt, just stay out!Use strong unique passwords everywhere and change them up frequently, especially if you suspect any accounts were compromised. Consider getting password manager software to create and store crazy secure passwords for you.Keep your software and operating systems updated with the latest security patches. The developers are always fixing vulnerabilities that sneaky hackers find.Be careful what you share and post online, because anything can be found and used against you by cyber creeps. Don't share too much personal info or inappropriate pics/vids that could come back to haunt you.Never opening files or clicking links from strangers or untrusted sources. That's one of the top ways malware gets spread around! Be wary of public WiFi hotspots too since they can be snooped on.If you do get caught up in some cyber monkey business like identity theft or stalking, report it right away! Authorities can help track down the bad guys and prevent it from getting worse.Lastly, university students should seriously consider studying cyber security themselves! The good guys need as many white hat hackers and security experts as possible these days. Withmore defenders than attackers, we can help make the internet a safer place for everyone.Well, that's my quick guide on the scary cyber crime world and how to fight back against those computer crooks! I know it's a lot to take in, but this stuff is super important, especially for university students joined at the hip with their tech. Stay safe out there, listen to your computer security lessons, and be cyber heroes! The internet is counting on you!。

计算机网络攻击和防范摘要：网络信息的安全和保密是一个至关重要的问题。
无论是在局域网还是在广域网中，都存在着自然和人为等诸多因素的脆弱性和潜在威胁。
关键词：计算机;网络;安全;防范引言：本文旨在介绍现在的网络安全问题，网络攻击的方式，步骤，防范。
防火墙的结构，类型，和具体应用。
使大家对于一般的网络攻击有所防范，可以用防火墙进行查杀和防护病毒。
正文：网络安全，是计算机信息系统安全的一个重要方面。
如同打开了的潘多拉魔盒，计算机系统的互联，在大大扩展信息资源的共享空间的同时，也将其本身暴露在更多恶意攻击之下。
如何保证网络信息存储、处理的安全和信息传输的安全的问题，就是我们所谓的计算机网络安全。
信息安全是指防止信息财产被故意的或偶然的非法授权泄露、更改、破坏或使信息被非法系统辩识、控制；确保信息的保密性、完整性、可用性、可控性。
信息安全包括操作系统安全、数据库安全、网络安全、病毒防护、访问控制、加密和鉴别七个方面。
设计一个安全网络系统，必须做到既能有效地防止对网络系统的各种各样的攻击，保证系统的安全，同时又要有较高的成本效益，操作的简易性，以及对用户的透明性和界面的友好性。
网络安全攻击，主要有四种方式L中断、截获、修改和伪造。
中断是以可用性作为攻击目标，它毁坏系统资源，使网络不可用。
截获是以保密性作为攻击目标，非授权用户通过某种手段获得对系统资源的访问。
修改是以完整性作为攻击目标，非授权用户不仅获得访问而且对数据进行修改。
伪造是以完整性作为攻击目标，非授权用户将伪造的数据插入到正常传输的数据中。
网络安全的解决方案一、入侵检测系统部署入侵检测能力是衡量一个防御体系是否完整有效的重要因素，强大完整的入侵检测体系可以弥补防火墙相对静态防御的不足。
对来自外部网和校园网内部的各种行为进行实时检测，及时发现各种可能的攻击企图，并采取相应的措施。
具体来讲，就是将入侵检测引擎接入中心交换机上。
入侵检测系统集入侵检测、网络管理和网络监视功能于一身，能实时捕获内外网之间传输的所有数据，利用内置的攻击特征库，使用模式匹配和智能分析的方法，检测网络上发生的入侵行为和异常现象，并在数据库中记录有关事件，作为网络管理员事后分析的依据；如果情况严重，系统可以发出实时报警，使得学校管理员能够及时采取应对措施。
二、漏洞扫描系统采用目前最先进的漏洞扫描系统定期对工作站、服务器、交换机等进行安全检查，并根据检查结果向系统管理员提供详细可靠的安全性分析报告，为提高网络安全整体水平产生重要依据。

Whether in the LAN or WAN, there are both natural and man-made factors, such as the vulnerability and potential threats.Key words: computer; network; security; preventIntroduction:This paper aims to introduce the current issue of network security, network attack methods, steps to prevent. The structure of the firewall, type, and specific applications. So that in general have to guard against network attacks can be used for killing the firewall and virus protection.The Main body:Network security is the security of computer information systems in an important aspect. As the opening of Pandora's Box, the computer systems of the Internet, greatly expanded information resources sharing space at the same time, will be exposed in their own malicious more under attack. How to ensure that network storage, security and the transmission of information security, is the so-called computer network security. Information security is to prevent information from the property have been deliberately or accidentally leaked authorized illegal, altered, damage or illegal information system identification, control; ensure confidentiality, integrity, availability, controllable. Information security, including operating system security, database security, network security, virus protection, access control, encryption and identification of seven areas. Design of a network security system, we must not only effectively prevent the system to a wide range of network attacks, guarantee the safety of the system, and also have a highercost-effectiveness, operational simplicity, and transparent to the user interface and friendly.In the form of network security attacks,there are four main ways L interruption,interception, modification and forgery.Interruption of availability is the object of the attack, which destroyed the system resources, so that the network is not available.Intercepted by the object of the attack the confidentiality, non-authorized users access to a means of access to system resources.Modify the object of the attack on the integrity, non-authorized users gain access not only data but also to be amended.Forged by the integrity of the object of the attack, non-authorized users to insert forged data to normal data transmission.Network security solutionsFirst, the deployment of Intrusion Detection SystemAbility of intrusion detection is a measure of an effective defense system is an important factor in a complete, powerful intrusion detection system, a complete firewall can make up for the relative lack of static defense. From the external network and the campus network of the various acts of real-time detection, to detect all possible attempts to attack and take corresponding measures. Specifically, intrusion detection is to switch on the engine access center. Intrusion Detection System Intrusion Detection set, network management and network monitoring functions, both inside and outside the network in real-time capture of all data transmission between the use of built-in features of database attacks, the use of pattern matching and intelligence analysis to detect the occurrence of network intrusions and anomalies, and in the database record of the incident, as a network administrator based on hindsight; if in serious condition, the system real-time warning can be issued so that the school administrators to take timely measures to deal with.Second, vulnerability scanning systemUsing the most advanced system of regular vulnerability scanning workstations, servers, switches and other safety checks, and in accordance with the results to the system administrator to provide detailed and reliable analysis of the security, to enhance the overall level of network security have an important basis.Third, the network version of the deployment of antivirus productsIn the network anti-virus program, we eventually have to reach a goal is: To put an end to the LAN in the whole virus infection, dissemination and attack, in order to achieve this, we should be in the entire network at risk of infection and the spread of the virus to take place The anti-virus tools. At the same time in order to effectively and quickly implement and manage the entire network of anti-virus system, should be able to remotely install, smart upgrade, remote alarm, centralized management, distribution of a variety of functions such as killing.Forth, the network host operating system security and physical security measuresNetwork firewall as the first line of defense and can not fully protect the internal network, must be combined with other measures to improve the safety of the system level. After the firewall is based on the network host operating system security and physical security measures. In accordance with the level from low to high, namely, the physical security of the host system, the core operating system security, system security, application services security and file system security; At the same time,host security checks and bug fixes, as well as a backup safety system as a supplementary safety measures. These constitute the entire network system, the second line of defense, the main part of a breakthrough to prevent the firewall as well as attacks from within. System backup is the last line of defense network system, used to attack after the System Restore. The firewall and host security measures is the overall system security by auditing, intrusion detection and response processor constitute the overall safety inspection and response measures. It from the network system firewall, network host or even directly from the network link layer on the extraction of network status information, as input to the intrusion detection subsystem.
