What is WiFiPineapple? I believe you all have your own answers to this question. Here is a quote from radiowar: since 2008, WiFi PineApple has become the most popular security testing device in open source wireless security.
The predecessor of snmp simple Network Management Protocol (SNMP) (Simple Network Management Protocol, simple Network Management Protocol) is simple Gateway Monitoring Protocol (SGMP), which is used to manage communication lines. Then, people pay attention to S.
Splunk provides very powerful data visualization capabilities comparable to Tableau. Refer to the following map data for display:
With the accelerated penetration of the Internet, it can be said that the network has become an indispensable part, which is called the fifth largest sovereign space after sea, land, air and space. Just as the territory of the country is inviolable, the cyberspace of our country is also inviolable, so network security is also very important. Especially recently.
I believe everyone will not be unfamiliar with the data. Jack Ma put forward the idea of changing from the IT era to the DT era a few years ago. And now we have basically reached a consensus, that is, data has become the "oil" of the digital age. As for the data, should we also pay attention to the data while using it?

The simple description of the host communication of arp deception principle is shown above. PC1 and PC2 are in the same network segment. PC2 wants to communicate with PC1. Due to the communication mechanism of Ethernet, PC2 needs to know the mac address of PC1 first and communicate with PC1 through mac address. PC2 will pass its own ar first.
RIP protocol can not adapt to the network environment when networking using RIP protocol, but with the development of the network, expanded into the situation shown in figure 9.1, the increasing number of devices makes RIP protocol unable to adapt to this network environment, resulting in the current R1 and R16 router users can not access each other, figure
As an open source storage engine, RocksDB supports the ACID feature of transactions, and concurrency control is necessary to support I (Isolation) in ACID. This paper mainly discusses the implementation of the locking mechanism of RocksDB. The details will involve source code analysis.
