网络安全与防火墙 英文文献翻译

网络安全技术英语With the rapid development of information technology, the Internet has become an indispensable tool in our lives, bringing us great convenience. However, along with the convenience, we also face various risks and threats. Therefore, it is necessary to improve our network security technology.First of all, a strong firewall is essential for network security. A firewall is like a protective shield that stands between our computer and the Internet. It helps to filter out and block malicious attacks, such as viruses, worms, and Trojans. By analyzing the data packets and monitoring the network traffic, the firewall can identify suspicious activities and take prompt actions to prevent intrusion.Secondly, using encryption technology is another effective way to enhance network security. Encryption is the process of converting plain text into cipher text, which is not readily understandable by unauthorized users. By applying encryption algorithms, sensitive information, such as passwords and credit card numbers, can be securely transmitted over the network. Even if the data is intercepted, it is extremely difficult for hackers to decrypt and obtain the original content.In addition, regularly updating the system and software is crucial for network security. Software developers release updates and patches to fix vulnerabilities and bugs that can be exploited by hackers. By keeping our system and software up to date, we can prevent potential security breaches and ensure the smooth operation of our network. It is also important to install antivirussoftware and scan the system regularly to detect and remove any malware that may have been accidentally downloaded.Furthermore, using strong and unique passwords is a fundamental measure to protect our network security. Weak passwords, such as simple words or numbers, are easily cracked by brute-force attacks. To create a strong password, it is recommended to use a combination of uppercase and lowercase letters, numbers, and special characters. It is also advisable to change passwords regularly and avoid reusing passwords for different accounts.Lastly, educating and raising awareness among users is essential for network security. Many security breaches are caused by human error, such as clicking on phishing links or opening suspicious email attachments. Therefore, it is important to educate users on how to identify and avoid potential threats. Regular training sessions and workshops can provide users with the necessary knowledge and skills to protect themselves and their networks.In conclusion, network security plays a vital role in our daily lives. By implementing strong firewalls, encryption technology, updating systems and software, using strong passwords, and raising awareness among users, we can effectively enhance our network security and protect ourselves from various risks and threats.。

Research of Network Security and Firewalls Techniques Abstract:As the key facility that maintains the network security , firewalls take the purpose of establishing an obstacle between trust and trustless network, and put corresponding safety strategy into practice. In this paper , the computer network security and the techniques of firewalls were mainly discussed, the concept and classification of the firewalls were introduced. It also introduced three kind's of basic implement techniques of the firewalls: Packet filtering , Application Proxy and Monitor model in detail. Finally described the trend of development of the firewalls techniques in Internet briefly.Key words: network security, firewalls, Packet filtering, monitor1. IntroductionNow with the computer network and e-commerce used widely, network security has become an important problem that we must consider and resolve. More and more professions. enterprises and individuals surfer from the security problem in different degree. they are looking for the more reliable safety solution . In the defense system adopted by network security at present, the firewalls stand the very important position.As the key facility that maintains the network security. firewalls take the purpose of establishing an obstacle between trust and trustless network, and put corresponding safety strategy into practice.All the firewalls have the function to filter the IP address. This task checks the IP packet, makes the decision whether to release or to abandon it according to the source address and destination address of the IP. Shown in Fig.I, there is a firewall between two network sections, an UNIX computer is on one side of the firewall, and the other side is a PC client. While the PC client asks a telnet request for the UNIX computer, the client procedure of telnet in the PC produces a TCP packet and passes the packet to the local protocol stack to prepare to send. The protocol stack fills it in one IP packet. then, sends it to UNIX computer through the path defined by the TCP/IP stack of PC. The IP packet can't reach the UNIX computer until it passes the firewall between the PC and the UNIX computer.Fig. I Ip Address FilteringThe application firewall is a very efficient means of network security on Internet,it is installed between the trust and trustless network, can isolate the connection between the trust and trustless network, and doesn't hamper people's access to the trustless network at the same time. It can isolate the connection between the risk area (namely there may be a certain risk on Internet) and the safe area (LAN), and doesn't hamper people's access to the risk area at the same time. Firewall can monitor the traffic flowing in and out from the network to finish the task seemingly impossible;it only allows the safe and checked information to enter into, and meanwhile resists on the data that may bring about the threat to enterprise. As the fault and defect of the security problem becomemore and more general, the invasion to the network not only comes from the super attack means, but also may be from the lower-level mistakes or improper password selections on the configuration. So, the function of the firewalls is preventing the communication that not hoped and authorized passes in and out of the network protected. forcing the companies to strengthen their own network security policy. The general firewalls can achieve the following purposes: First, restraining others from entering the inside network, filtering the unsafe service and illegal user; Second, preventing the invaders from closing to your defense installation; Third,limiting the user to access the special site; Fourth,providing convenience for monitoring the Internet security.2. The classification and implement technology of firewallsAn integrated firewalls system usually consists of screening router and proxy server. The screening router is a multi-port IP router. it check the each coming IP packet according to the group regular to judge whether to transmit it. The screening router gets information from the packet. fot example the protocol number. the IP address and port number that receiving and sending massages. the flag of link even some other IP selections. filtering IP packet. The proxy server are server process in the firewall. it can replace the network user to finish the specific TCP/IP function. A proxy server is naturally a gateway of application layer. a gateway of two networks joined specific network application. Users contact with proxy server by one of the TCP/IP application such as Telnet or FTP. the proxy server ask the users for the name of the remote host. which users want to access. After the users have answered and offered the correct users' identities and authentication information, the proxy server communicates the remote host, act as the relay between two communication sites. The whole course can be totally transparent to users.There are mainly three types in the firewalls: packet filtering. application gateways and state detection.Packet filtering firewall works on the network layer.it can filter the source address. destination address. source port and destination port of TCP/IP data packet. It has advantages such as the higher efficiency.transparent to user. and users might not feel the existence of the packer filtering firewall, unless he is the illegal user and has been refused. The shortcomings are that it can't ensure the security to most services and protocols, unable to distinguish the different users of the same IP address effectively,and it is difficult to be configured, monitored and managed. can't offer enough daily records and warning.The application gateways firewall performs its function on the application layer, it connects with specific middle-joint (firewall) by a client procedure, and then the middle-joint connects with the server actually. Unlike the packet filtering firewall. when using the firewall of this kind. there is no direct connection between the outside networks. so even if the matter has happened in the firewall. the outside networks can't connect with networks protected. The application gateway firewall offers the detailed daily records and auditing function, it improved the security of the network greatly. and provides the possibility to improve the security performance of the existing software too. The application gateways firewall solves the safety problem based on the specific application program. the products based on Proxy will be improved to configure the service in common use and non-standard port. However. so long as the application program needs upgrading. the users based on Proxy will find that they must buy new Proxy server. As a technique of network safety. Firewall combined with proxy server has simple and practical characteristics, can reach a certain security request in case of not revising the original network application system. However. if the firewall system is broken through. the network protected is in having no state of protecting. Andif an enterprise hopes to launch the business activity on Internet and carry on communication with numerous customers. it can't meet the demands. In addition, the firewall based on Proxy Service will often makes the performance of the network obviously drop.The third generation of firewall takes the detection technique of state as the core, combines the packet filtering firewall and application gateways firewall. The state detection firewall accesses and analyzes the data achieved from the communication layer through the module of state detection to perform its function. The state monitor act as firewall technique. it is best in security perfonnance, it adopts a software engine.which executes the tactics of network security on the gateways, called the detection module. On the premise of not influencing the network to work normally, detection module collects the relevant data to monitor each of the network communication layers, collects a part of data, namely status information, and stores the data up dynamically for the reference in making security decision afterward. Detection modulesupports many kinds of protocols and application program, and can implement the expansion of application and service very easily. Different from other safety schemes, before the user's access reaches the operating system of network gateways, the state monitor should collect the relevant data to analyze, combine network configuration and safety regulation to make the decisions of acceptance, refutation, appraisal or encrypting to the communication etc Once a certain access violates the security regulation, the safety alarm will refuse it and write down to report the state of the network to the system management device. This technology has defects too, namely the configuration of the state monitor is very complicated, and will decelerate the network.3. New generation technique of firewallsAccording to the present firewalls market, the domestic and international manufacturers of firewall can all support the basic function of the firewall well,including access control, the network address transform, proxy, authentication, daily records audit etc. However, as stated before, with the attack to the network increasing, and user's requisition for network security improving day by day, the firewall must get further development. Combine the present experience of research and development and the achievement,some relevant studies point out, according to the development trend of application and technology, how to strengthen the security of firewall, improve the performance of firewall, enrich the function of firewall, will become the problem that the manufacturer of firewalls must face and solve next.The purpose of the new generation firewall is mainly combining the packet filtering and proxy technology, overcoming the defects in the safety respect of two; being able to exert the omnidirectional control from the layer of data chain to the application layer; implementing the micro-kernel of TCP/IP protocol to perform all the security control on the layer of TCP/IP protocol; based on the micro-kernel above, making the speed to exceed thetraditional packet filtering firewall; Offering the transparent mode of proxy. lightening the configuration work on the client; Supporting the data encryption and decryption (DES and RSA ), offering the strong support to the Virtual Private Network VPN; hiding the Inside information totally; producing a new firewall theory.The new techniqe of firewalls has not only covered all the functions of traditional packet filtering firewalls, but also has remarkable advantages in opposing overall the attack means of IP deception, SYN Flood, ICMP. ARP, etc. strengthening proxy service, merging it with packet filtering, then adding the intelligence filtering technology to make the security of the firewall rising to another height.4. ConclusionNow the firewall has already been widely used on Internet, and because of its characteristic of not limited to the TCP/IP protocol, it has more vitality outside Internet progressively too. To be subjective, the firewall is not the omnipotent prescription of solving the problem of network security, but only a component of the network security policy and tactics. However, understanding the technology of firewall and learning to use it in actual operation, believing that every net friend may be benefited a lot from the network life in the new century.外文资料翻译译文摘要：作为关键设施，维护网络的安全性，防火墙采取建立信任与不可靠的网络障碍的目的，并落实相应的安全策略。
