Descriptive Language

Network Security Logs are the records of the important activities and changes of the network, which not only records the state changes of network or mainframe at any time, but also provides the data bases for the network administrators to conduct network management. How to obtain the effective information of security events from the logs with different formats, thus realizing the detection, analysis and evaluation of the security events, has always been the key point to improve the important content of information security protection and focused on by the network administrators. The paper presents a kind of descriptive language of computer network security focusing on the log management, which realizes the uniform description of the common logs in the network with its effectiveness being verified in the actual network environment. It provides the infrastructural support to improve the early warning capacity towards the information security events.

Computer networks are basically not safe to access freely. Security gaps in the network can be seen by irresponsible people with various techniques. Opening a port for access carries a high risk of being attacked by an attacker. In this connection, network administrators are required to work more to be able to secure the computer network they manage. One form of network security that is often used by network administrators in server management is through remote login such as ports on telnet, SSH, etc. A port that is always open is a network security hole that can be used by people who are not responsible for logging into the server. Focusing on these problems, in this study, Random Port Knocking is the right way and can be used to increase network security. With Random Port Knocking, the port will be opened as needed, the port will automatically change when it fails to log in more than three times and IP will automatically be blocked and access will not continue so that attacks on the network can be avoided and network security stability can be further improved. The final result of this research shows that the method applied in this research makes server safe. Because port randomization and IP block make irresponsible parties try harder to penetrate firewall walls.

Writing a chapter on network security is something like writing a brief introduction to flying a commercial airliner. Dissimilar, data communications of the past, today's networks incorporate varied devices that handle the data because it passes from the sender to the receiver. The first question to address is what we mean “network security”. Network security consists of the provisions and policies adopted by a network administrator to prevent and monitor unauthorized access, misuse, modification, or denial of a computer network and network-accessible resources. A generic definition of security is “freedom from risk or danger and safety”. However it is not only human errors that can cause problem to network security, problems can also be caused by natural forces like fire breakouts, earthquakes, floods lightning etc. The ways network administrators think about securing networks has been changed by an increasingly dynamic and technically challenging risk environment. Security is an assessment of risk. Secure environments are designed and developed through an intentional effort.

Computers are closely related to our life and work. We have entered an era in which computers are not available in all walks of life. Among them, many important documents and materials will be stored in the form of electronic files in the computer. However, computers are not absolutely safe, and cases of information theft occur from time to time. Most people usually keep information confidential in the form of encryption. How to avoid the problem of computer information security. Computer network security involves all aspects. To solve these problems, there are many levels of technology, such as cryptography technology, network security technology and so on. Our country has also done a lot of research on the security protection of computer network technology, and these research results have also achieved certain results in the actual construction of computer network. In order to ensure the normal operation of computer networks, ensure information security and prevent information leakage and theft, a special protection system has been established to ensure the security of computer network information by setting up computer detection, security assessment and other links. However, with the rapid development of science and technology, the updating of electronic products is faster and faster, and the challenge of Wechat for network security information is more severe. How to protect computer network information security needs to be solved urgently, this paper discusses this.
