网络安全普及英文缩写
网络安全普及英文缩写With the rapid development of the Internet, network security has become a major concern for individuals, businesses, and governments around the world. To effectively discuss network security topics, it is important to be familiar with the common abbreviations used in this field. Here, we will introduce some of the most commonly used abbreviations related to network security:1. VPN: Virtual Private NetworkA VPN is a private network that encrypts and securely connects users across a public network, such as the Internet. It creates a secure connection to protect data transmission and ensure privacy.2. TLS: Transport Layer SecurityTLS is a protocol that provides secure communication over a network. It is commonly used in web browsers to establish a secure connection between a client and a server, preventing eavesdropping and tampering.3. SSL: Secure Sockets LayerSSL is a predecessor of TLS and is used to ensure secure communication between a client and a server. It provides encryption and authentication to protect sensitive information during transmission.4. IDS: Intrusion Detection SystemAn IDS is a security system that monitors network traffic for suspicious activities or potential threats. It detects attacks and alerts system administrators to take appropriate actions.5. IPS: Intrusion Prevention SystemAn IPS is similar to an IDS, but it not only detects network attacks but also actively blocks and prevents them from compromising a network. It can be a standalone system or integrated with other security solutions.6. DDoS: Distributed Denial of ServiceA DDoS attack is an attempt to overwhelm a target network or website by flooding it with a massive volume of traffic from multiple sources. The goal is to make the targeted system unavailable to its users.7. ACL: Access Control ListAn ACL is a set of rules that defines what network traffic is allowed or denied to pass through a network device, such as a firewall or router. It helps protect a network by filtering and controlling traffic flow.8. WAF: Web Application FirewallA WAF is a firewall specifically designed to protect web applications from attacks, such as SQL injection, cross-site scripting, and brute force attempts. It monitors and filters HTTP and HTTPS traffic to ensure application security.9. OTP: One-Time PasswordAn OTP is a password that is valid for only one login session or transaction on a computer system or network. It provides an extra layer of security, as the password changes with each use and is not reusable.10. DMZ: Demilitarized ZoneA DMZ is a separate network segment that acts as a buffer zone between an internal network and the Internet. It is commonly used to host public-facing servers, such as web servers, while providing an additional layer of security.These are just a few of the many abbreviations related to network security. Staying familiar with them will help individuals and organizations stay informed and up-to-date with the latest developments in network security. Remember, cybersecurity is an ongoing battle, and being knowledgeable about these abbreviations is an important step in protecting our digital assets.。
网络信息安全英语练习题
网络信息安全英语练习题### Network Information Security Practice Questions1. Understanding Network Security Basics- Question: What is the primary function of a firewall in network security?- Answer: A firewall's primary function is to monitor and control incoming and outgoing network traffic based on predetermined security rules.2. Types of Network Attacks- Question: Differentiate between a DDoS attack and a phishing attack.- Answer: A DDoS (Distributed Denial of Service) attack overwhelms a website or server with a flood of traffic, making it inaccessible. A phishing attack, on the other hand, involves tricking individuals into revealing sensitive information, such as passwords or credit card numbers, through deceptive emails or websites.3. Cryptography- Question: Explain the difference between symmetric and asymmetric encryption.- Answer: Symmetric encryption uses the same key for both encryption and decryption, making it faster but requiring secure key distribution. Asymmetric encryption uses a pair of keys, a public key for encryption and a private key for decryption, which enhances security but is computationallyslower.4. Secure Communication Protocols- Question: What is SSL/TLS and why is it important for secure communication?- Answer: SSL/TLS (Secure Sockets Layer/Transport Layer Security) is a protocol used to provide secure communication over the internet. It is important because it encrypts data being transmitted, ensuring that it cannot be intercepted and read by unauthorized parties.5. Vulnerability Management- Question: How can organizations manage and mitigate software vulnerabilities?- Answer: Organizations can manage and mitigate software vulnerabilities by regularly updating and patching software, conducting vulnerability assessments, and implementing a strong patch management policy.6. Network Security Policies- Question: What are the key components of a network security policy?- Answer: Key components of a network security policy include access control, password policies, network segmentation, incident response plan, and user education on security practices.7. Wireless Security- Question: What is WPA2 and why is it preferred over WPA for wireless security?- Answer: WPA2 (Wi-Fi Protected Access II) is a securityprotocol for wireless networks that provides stronger encryption and is more secure than WPA. It is preferred dueto its use of the Advanced Encryption Standard (AES), whichis more resistant to hacking attempts.8. Intrusion Detection Systems (IDS)- Question: What is the role of an IDS in network security? - Answer: An IDS monitors network traffic for suspicious activity or policy violations. It can detect and alert administrators to potential intrusions or attacks, allowingfor a timely response to mitigate threats.9. Social Engineering- Question: How can social engineering attacks be prevented?- Answer: Social engineering attacks can be prevented by educating employees about the tactics used in such attacks, implementing strict security policies, and encouraging a culture of skepticism towards unsolicited communications.10. Incident Response- Question: What steps should be taken when a security incident is detected?- Answer: Upon detecting a security incident, stepsshould include isolating the affected system, collecting evidence, analyzing the incident, eradicating the threat, restoring affected systems, and reviewing the incident to improve security measures.11. Data Protection- Question: What measures can be taken to protectsensitive data?- Answer: Measures to protect sensitive data include data encryption, access controls, regular backups, and secure data disposal practices.12. Compliance and Regulations- Question: Why is compliance with data protection regulations important?- Answer: Compliance with data protection regulations is important to protect the privacy of individuals, maintain trust with customers, and avoid legal penalties and reputational damage.Remember, these practice questions are designed to test your understanding of network information security concepts and practices. It is essential to stay updated with the latest security trends and technologies to effectively protect your networks and data.。
NetworkSecurityPlatform1千兆位光纤主动故障旁路套件-McAfee
本文档介绍了 McAfee ® 1 千兆位光纤主动故障旁路套件（套件）的物品、安装方法、工作原理以及正常使用期间的预期功能，该套件用于具有标准小型可插拔 (SFP) 监控端口的 McAfee Network Security Sensor (Sensor) M 系列和 NS 系列型号。
本套件包含主动失效打开光纤绕过交换机（光纤绕过交换机）和所有连接组件，可将交换机连接到 Sensor 的监控端口。
可能还需要用其他电缆将绕过交换机连接到其他网络设备（如路由器或交换机）。
可能不需要使用套件中的全部组件。
例如，您只需要使用套件里两种电缆中的一种。
您可为下列 Sensor 型号配置光纤旁路交换机：NS9300、NS9200、NS9100、M-8000、M-6050、M-4050、M-3050、M-2950、M-2850 和 M-2750。
Sensor 上的 1 千兆位光纤监控端口具有失效关闭功能；因此，如果采用串联模式部署 Sensor ，则发生硬件故障会造成网络中断。
监控端口的失效打开工作模式要求使用此套件提供的可选外部光纤绕过交换机。
光纤绕过交换机安装到位后，交换机从双电源适配器接通电源（冗余电源使用的是两个独立电源）。
Sensor 工作时，交换机处于“On ”(打开) 状态，并将全部流量直接发往 Sensor 。
当 Sensor 出现故障时，交换机自动切换到绕过状态；串联模式下的流量将继续流过网络链路，但不再通过 Sensor 路由。
在 Sensor 恢复正常工作后，交换机返回到“On ”(打开) 状态，再次启用串联监控。
在 Sensor 正常的串联失效打开工作期间，光纤绕过交换机会向监控端口对发送检测信号（1 个/秒）。
如果光纤绕过交换机在设置的间隔时间内没有收到 3 个检测信号，则光纤绕过交换机会从数据路径中删除 Sensor 的监控端口对，并将 Sensor 切换到绕过模式，以提供持续数据流。

New Network Security Based On CloudComputingWeili Huang Information and Electron Department Hebei University of EngineeringHanDan,China997518268@ Jian YangInformation and Electron Department Hebei University of EngineeringHanDan,Chinayjbs11@Abstract—In this paper, we will have the combination of cloud computing and network security to research "cloud" firewall technology. Comparing the "cloud" firewall with the traditional firewall to further study the cloud computing, architecture and virtualization technologies in the "cloud" firewall. It will show the new concept of network security to the readers , which is about its advantages, development trends and possible risks .Keywords-Cloud;Firewall;CloudComputing;Clo-ud Terminal;Virtualization;Network SecurityI.I NTRODUCTIONOur requirements for the network environment was not limited to passive defense, so based on the current most popular cloud computing technology, a new generation of firewall technology, "coming with the clouds ." Cisco believes that the emergence of cloud firewall ,which means that the birth of the fifth-generation firewall, the former four generations are: software firewalls,hardware firewall, ASIC firewalls, UTM. SensorBase is the precondition of cloud firewall, it is the data center in the cloud and the largest email traffic monitoring network in the world, providing real-time view of global security threats and the "credit reporting service" of e-mail, SensorBase added botnet dominated database to enable it to monitor botnet sensitive development[1].The key technology of cloud firewall is based on cloud computing."Cloud" has a considerable scale,and the provider will build sensors on the major network operators. Cloud computing supports users to use a variety of terminal to get application services in any position. By the cloud computing , we can make better use of network, as long as you are in the "cloud". You can make full use of the "The Top of Cloud" on your terminal , and we always keep in touch with other terminals in the "cloud" , so if it is found somewhere in the attacks, immediately the some terminal notifies the other places to stop the attacks and deploy plans. This is the core idea in the cloud firewall —— it will turn the passive protection into dynamic, collaborative and proactive protection.II.C LOUD F IREWALL I NTRODUCTIONA. Tthe Principle of Cloud FirewallThe most essential feature of cloud firewall is its dynamic and intelligent, and its technology is to take full advantage of "cloud" to sample and share threat informations dynamically and in real time, which ultimately we can realize active and re-active security services. The whole "cloud" is a large group, in this group there is a largest "competent department", which is known as the "The Top Of Clouds".It can collect detailed information threats on the Internet constantly, including the continuous attacks, botnet harvest , malware outbreaks and DarkNets and so on. By passing these real-time information to the cloud firewall, you can filter these attackers before the malicious attackers have the opportunity to damage the important property.2010 Second International Workshop on Education Technology and Computer ScienceHowever, these search behavior and passing behavior are based on cloud computing principle, it will turn a large computing program into numerous small subroutines automatically, and then they are assigned to the large system which is made with a lot of servers.These subroutines were searched ,calculated and analysed to pass the consequence to users.Every user can apply to join the "cloud", as long as you are in the "cloud", you will be able to receive timely security information coming from clouds and processing methods, and you also participated in the transmission to achieve cooperative transmission. By this technology, network service providers can deal with tens of millions or even billions of dollars of information in seconds.It is like "super computer". As shown in Fig. 1[3]:Fig. 1 The Active Defense of Cloud FirewallSo, the defensive and aggressive attack of cloud firewall is just like the following codes to show˄quote "Microsoft Intemet Controls" in the project˅˖Dim dWinFOlder As New ShellWindowsDim eventIE AsSHDocVwˊIntemetExplorerDim objlEAsObjectFor Eachobj~EIndWinFolderSet eventlE=objlEeventlEˊQuitˊNextBy these codes,the personal firewall which is based on cloud security is like a big hand.When you open a malicious link,the cloud firewall will push you to a safe area forcibly, that is to say,it is redirected to a safe URL or HTML documents which we are designed; and it is like a car towing rope, when the car bogged down in the quagmire, the cloud firewall will put you out[2].B.The Features of Cloud FirewallThe top of cloud and these small usersendpoints are just like antennaes, and constantly they explore useful information,thus breaking the protection of traditional firewall , which is passive and waiting.Just for the attack, the traditional firewall is completely passive defence, and it does not know where is the attack and how to attack. The core of the firewall is static ruleprotection,that is to say,after the customers buy a firewall, the suppliers configure matching security policy which is according to customer's pared with traditional firewalls,the cloud firewall updates static protection strategy dynamically to add proactivity to network security,it has some significant features[4]:zFirstly, the cloud firewall freezes botnets. For one thing , the cloud firewall can find malicious Web site in a short time relatively to stop users to access to these sites; for the other thing, if the users' computers become "zombie" or have Trojan Horse, the cloud firewall can stop the computers to send external master site information.zSecondly, the cloud firewall let the world's IPS be Intelligent linkage. The top of cloud was added botnets master database anddynamic strategies to SensorBase to monitor the dynamics of botnets sensitively.If some Internet address have some questions,it will be blocked, and the top of cloud will try to update the information of SensorBase in the shortest time.zThirdly, the cloud monitors Netflow V9 to achieve NOC / SOC combo. Netflow provides a session-level view of network traffic to record every service information from TCP / IP . Its function includes abnormal traffic monitoring, high-speed sampling and timed control ,the amalgamation of network and security, the standard network element management. III.T HE C LOUD C OMPUTING IN C LOUDF IREWALL ˖A. About Cloud Computing ˖Cloud computing is still in its infancycurrently.About the definition of cloudcomputing is still controversial, which aremultiple versions, so far there is no oneconclusive. Cloud computing is not a specifictechnology, but a computing concept or a computing model. Cloud computing is the development of parallel computing, distributed computing and grid computing , or it is commercial realization of the concept of computer science. Cloud computing is themixed-jump result of the evolution of concepts of virtualization, utility computing, IaaS, PaaS, SaaS[5]. It has huge scale, virtualization, high reliability, commonality, high scalability and service on demand. Large scale is its greatest feature,the key of cloud computing is to have enough information collection points and computing capacity.That is to say,usually for the large data calculation, we can divide it into many small sub-blocks to many computing terminals which are in the "cloud". So we can get a large-scale computing system, and the computing capability of this system is better than anyhigh-equipped computer. In this computing model, all servers, networks, applications and other parts related with the data center are provided to the IT department and end-users through the Internet. Customers are only connected to the "cloud", they can access to infrastructure services, platform ( operating system) services, or software as a service —— such as SaaS application, the "cloud" is possible to be the internal data center or computer which has the same function.B. Computational Logic in CloudComputing ˖About n-term computing is defined[6]:F is a computing, and x1ˈx2ˈĂĂ,xn are n variable parameters for computing. So F is n-term computing, S is the result of computing,such as S = F ( x1 , x2 , Ă , xn)˗if a1ˈa2ˈĂˈan were the value data of x1ˈx2ˈĂˈxn, soS= F( a1 , a2 , …, an) is a calculation for F, and S is the result.About n-term rule is defined[7]: If A1ˈA2ˈĂˈAn are n antecedents, B is conclusion,which is called n-term rule as R, R can beexpressed as "If A1 , A2 , Ă, An , then B" DŽCloud computing as a whole calculation process is shown in Fig. 2:Fig. 2 Cloud computing processC.Cloud Firewall Structure Ba Computing ˖on-d ment is the core of cloud com tion of deployment, which they need virtualization technology, high-performance effectively, cloud firewall architecture must be auto ogy to reduce or eliminate manual deployment and management tasks,but it sed on Cloud automa Cloud firewall is based on cloud computing,emand deploy puting. So we have to solve the dynamic reconfiguration of resources, monitoring andstorage technology, processor technology,high-speed Internet technology as the foundation[8-9]. It is shown in Fig.3:invokeDynamicallyReconfigurable,Monitoring ,AutomationVirtua ance StorageProcessor TechnologyFig. 3 The invoking structure of cloud firewalIn order to support cloud computing automation technol nomous, that is to say,they need embeddedallows platform to respond intelligently to theirlizationHigh-perform Cloud Computingapplication requirements. Cloud computing structure must be sharp, which is able to makequick response for changes in the load and demand signal.In other words, the clouds cluster must be able to quickly respond to certain malicious attacks, and rapidly from one to pass to other points, to be co-processing.Typically, "cloud" have a large number of servers, and resources are dynamic, and it need real-time, accurate and dynamic resource information. Cloud computing monitored and manhow they do data mining forsample data , and then form a addil" cloud scanningservid itsapplication form had also presented very manykinds.One serwith the fime, and by thecalcaged all the resources in the computing resources pool by a monitor server,and it configured and monitored every resources server by deploying “Agent” on all the servers in the cloud,and it can pass information data to the data warehouse regularly.Monitor server analysised the using data which is in the "cloud" in the data warehouse and tracked the availability and capability of resource,which offered information for the exclusion of lesion and the balance of resource[10-11].D. Based on the File Reputation Technology˖The real technical focal point of "Cloud security" lies inthe collection ofnew identification technology in the clouds. After ng the concept of cloud security to firewall,the new cloud-client file reputation (CCFR) technology will become the users' focus.In the cloud security,the core is cloud-client file reputation,which is to change the mode to manually update the protection.For the ordinary users ,the cloud security which is based on the cloud-client file reputation can be understood:It reached interaction between "anti-virus vendor's computer cluster" and "user terminal" ,which can change the issue of the virus code into the uploading of the characteristics of the file to compare in the top of cloud.But it cannot upload the whole codes to compare,rather than features in the files.The whole process is just some milliseconds[12].From general technology, CCFR reduces the updates of client-side in the traditional update-mode, most of these updates is now available "local or globaces, which would significantly reduce the re-update mode of the terminal system to minimize the download of anti-virus codes. Traditional client-side virus pattern updates, about 2-3 times per day, 2-3Mb download traffic every time , while the CCFR client cloud virus code only updates once a week, 2-3Mb every time. Precisely ,CCFR can decrease virus database in the client-side about 90%[13].IV.T RENDS AND R ISKS˖At present, the cloud firewall is still in the embryonic stage of development,antrend,which is to connect the uirewall software platforms closely by Internet in order to form a huge monitoring for Trojan / malicious software , spyware network. Every user will contribute to the firewall "Cloud security" , while sharing the results from the other users. This is similar to the P2P. If we can really dig into the user's enthusiasm , build a new security system is not impossible. But now, users don't still fully accept this cloud firewall, which means everyone's enthusiasm was not high .This is something we have to face.Another trend ,is to set up a sufficient number of servers (tens of thousands or even more) in the world to collect application requests from global users in real tulation in the top of cloud,it is to judge the safety of these requests. For example,a user requests to connect a corporate Web site. By a number of technical indicators ,the operator will determine whether the site's URL was normal and secure, whether the web links embedded in the text and Button were normal and secure, whether the user will be directed to non-performing Web site or lead to other dangerous behavior. If the site is secure, the user can link to, but if not, this link in the text will be block ,not the whole web page. Accordingly, theproblematic URL will also be added to the problem database in the top of cloud.Once theother usersĄrequests access to this data, according to the problem database ,"the top of cloud" can decide whether to allow the user to access by judging the data [14].The first challenge cloud firewall faced was network environment issues. If security threats had emerged and destroyed the network connection, at this time, then no matter how stronghave to achieve the whole cloud security protection model finally,ch se. Becauseprocessing on large clusters. In Proc.33-78.Āy_2 [4]ysis with Sawzall.Scientific Pr m13(4),pp.12-30.[6]2007..[7]EEmputing, HongLBM[10] f, and. I m ond[12]n[13] large-scale[14] . Active and accelerated learning of cost[15] R.oc. 9th CCGrid. IEEE Press, 2009."the top of cloud" to protect, the client's losses are inevitable. Second, the cloud security standards in the cloud firewall is still in a chaotic state, there is no uniform standard, various vendors are still fighting each other, vendors have their own standards.So the client may get a different judgement, which is harm to unify the cloud security in future. The root of these problems was that cloud computing has not yet been spread extensively, complete cloud computing environment is still not perfect.That is to say,the cloud security was born from the cloud computing will not lay a good foundation, so now cloud security environment is not safe enough , and only after the popularity of cloud computing , will cloud security begin truly.V.C ONCLUSION˖Cloud firewall is a popular form of security software, but it is a tightly fur products, wewhi is the real purpoof the agility and high spreadability of the cloud security , it determined its security model is definitely the future development trend, and even the most difficult to guard against the so-called "zero-day attacks" [15] ,this hacker is also easy to be guarded. But, before cloud computing become mainstream,the cloud security will not lay a good foundation.That is to say,we will have a long road to real cloud security,which will need the strong support from all users and the unity from the major manufacturers.Only in this way,can achieve the real cloud security.R EFERENCES[1] H. chih Yang, A.
