Article title: quickly locate network services in Linux. Linux is a technology channel of the IT lab in China. Includes basic categories such as desktop applications, Linux system management, kernel research, embedded systems, and open source. For security reasons, it is necessary to find out which services are runnin

Author: panzhutingThis article describes the characteristics, implementation concepts, and principles of network security emergency response from the perspectives of "looking at emergency response", "Three Views", and "Three Views of emergency response. The article first introduces the unique position and complexity of emergency response in network

Wireless NetworkAnd wirelessLanThe emergence of this greatly improves the speed and quality of information exchange, and provides many users with convenient and sub-even network services, however, due to the characteristics of wireless networks, security risks are also caused. With the rapid development of information technology, many networks have begun to achie

Network File System Services common to NFS SMBThe primary function of the RPC service is to record the port number for each NFS feature and to pass the information corresponding to that port and function to the NFS customer service for the requested data when requested by the NFS Customer service client.Process:1. Start the RPC service first2, and then start the NFS service3,nfs the port that the service in

Do you often get bored with a long string of Web sites? Do you often encounter long and hard-to-remember websites?

such as: Computer room, intranet, company network, etc.).It is not possible to attack on the external network (Internet, LAN in non-local area).(d) Prevention of port scanning. 1. PrincipleGenerally speaking, all ports open to the computer are potentially dangerous. Some of the necessary communication ports (such as 80, 8080) cannot be shut down, but we can turn them off for most ports, especially Windows

Different modules of enterprise-class products can be installed on different machines. Third, the state detection mechanismFIREWALL-1 uses Checkpoint's state detection (Stateful inspection) patent technology to differentiate application types with different

devices, manage wireless Internet users reasonably, standardize the working mode and security settings of wireless network devices, and clarify the use scope and access permissions of internet users. For example, do not connect laptops with important unit information to the wireless LAN. Do not share the information in the wireless LAN. do not attach mobile devices to the wireless LAN, protection of the wo

Enhanced Network Security Broadcast on a shared-bandwidth LAN will inevitably cause security issues, because all users on the

This protocol can be used to create end-to-end one-sentence communication. However, the data information in the transport layer mainly depends on the effective Services provided by the network layer, which is greatly affected by the network
