Recently, a mining virus using Powershell has broken out frequently in the enterprise network. The virus uses the WMI+Powershell method to carry out file-free mining and stays in memory for mining. The mining virus of Powershell has the high level of no files.
IP address conflict is a common problem in network management. Especially in the enterprise local area network, due to the existence of management and control strategy, someone will always try to change the IP address to bypass the control, get more Internet access and higher bandwidth. If the modified IP conflicts with the IP sent by the company's server, it will go straight.

How to measure the degree of similarity or difference between data points is the basic problem of clustering algorithm, which will directly affect the effect of clustering analysis. The most intuitive method is to use distance function or similarity function. A common method for calculating the degree of similarity or difference. 1. Calculation formula 1.Minkowski dista
For the data center, the importance of operation and maintenance work is self-evident. Operation and maintenance management is the longest phase in the data center life cycle. The work of the operation and maintenance of the data center is mainly to systematically plan, organize, coordinate and control the management objects of the data center, and to manage the information system services.
Experiment 4: DAI1. This experiment is done on the basis of experiment 3. DAI is enabled on 2.SW1 and Fa0/23 is designated as Trust. Clear R1 ARP entry. 3. Observe and think about the phenomenon on R1 by ping10.10.1.4/10.10.1.3
