. Unfortunately, apart from XP, in other versions of Windows, even if this is done, after receiving the forged ARP reply, the system will update its ARP cache and replace the old MAC address with the new MAC address, therefore, arpspoof cannot be defended against. In addition, there is a defect in adopting static ARP, that is, if the network is large, the workload will be very large. ARP listener DetectionThe first is to use a tool that detects the corresponding IP address and MAC address, such

Packetfence is an openSource codeNetwork access control tools, which are actively maintained and used by some large organizations. It can effectively ensure network security, including different types of networks from small to very large. Features of packetfence include registering new network devices, detecting abnormal network activities (in combination with SNORT), and isolating problematic network devices, based on registered and planned vulnera

Snort is now recognized as the best IDs on Linux . Using SELinuxSELinux is used to secure Linux, and with it, users and administrators can gain more control over access control. SELinux adds finer granularity control to access control. Unlike the ability to specify only who can read, write, or execute a file, SELinux lets you specify more control over who can delete links, append only, move one file, and so on.

Programmers are a very special group, because they have a long time to deal with the computer's character and temper is relatively similar. Of course, since it is a person, of course, there will be character, but also will have a temper. Now, let me take a look at 10 things that can annoy the program. On the one hand we can look at the commonality of programmers, on the other hand we can look at the shortcomings of programmers. In any case, I hope they will be a help to your daily work. Tenth-b
