First of all, you need to know the ip address of the person you want to disconnect: use the command to scan the surviving hosts in the network: fping-asg 192.168.1.0 and 24 (which is set according to your own network segment), and then implement the disconnection command through the principle of arp: arpspoof-I network card-t

In my spare time, after thinking about what kind of technology will be often used in the local area network, or what technology the local area network should use to ensure its stability, I have the following list. VLAN data vlan Voice vlanGVRP (VLAN dynamic Registration Protocol) ensures all exchanges
Software Discovery guidelines: both An and * * will build the most vulnerable places on the surface, such as the old version of SSH or Apache;B, what you don't know, what will hurt you; delete / close special software packages you don't need, and be clear about the actual use of the license, which can help you spend
As far as security management is concerned, according to the eleven aspects of ISO27001, the first one is the so-called "security policy".

1. Experimental purpose 1. To learn and master the basic methods of programming based on WinPcap. 2. By monitoring IP packet flow, we can understand the working principle of IP protocol and the basic structure of IP packet. Second, the experiment content uses WinPcap to write a console program to monitor IP packet traffic.
Open source security operation and maintenance platform based on OSSIM whether a security operation and maintenance platform can be effective depends on the ability to collect data. If the data sources are missing, the upper correlation analysis is likely to be biased. For network security equipment, it mainly collects its security log (including alarm) and the running status of the equipment.
