1. The existence and development inevitability of IDS (Intrusion Detection System) (1) complexity of network security itself, and passive defense methods are not powerful. (2) related firewalls: devices with network boundaries can be attacked by themselves, and some attacks are poorly protected. Not all threats come from outside the firewall. (3) Easy intrusion:

Currently, computer networks face two types of threats: one is the threat to information in the network, and the other is the threat to devices in the network. There are many factors that affect the computer network, mainly network software vulnerabilities and "backdoors". These vulnerabilities and defects are exactly

The subnets is connected to router via a network interface on the OvS Br-int Bridge. The network interfaces are

The Transportation Management Information System of the Ministry of Railways will move railway operation management from experience to modernization. With the rapid development of China's economy, the transportation volume of Railways has increased significantly, requiring the transition from experience management to modern management. Management personnel must have a complete information system to obtain timely, accurate, and complete information and provide decision-making support. The Ministr

restored to normal without packet loss, it seems that this network problem is completely caused by this network management host, but this phenomenon is hard to understand. Why does the network management host cause network problems. We use the Decode function of Sniffer to Decode the captured

the source address and destination address refers to the network card hardware address (also called MAC address), the length is 48 bits, is in the network card Factory curing.(2) Note that the data received by the network card chip (for example, dm9000a) is a long string of data as shown above, including the Ethernet frame header, the IP datagram header, the Tra

The two-level structure of the IP address may cause the IP address utilization to be low. For example, each network in the B-type network can accommodate more than 60 thousand hosts, but the average enterprise does not need such a large capacity, therefore, IP resource utilization is low. In addition, when an enterprise needs to add a new network, it needs to app
