From the perspective of Web hosts, various built-in utility tools of servers can monitor ping or scan activities and record them into log files. If you find that icmp echo packets from a system or network are in a suspicious mode when you view the logs, it may mean some

data reconnaissance, forces the switch to send all data packets and conversation data to him. You can run the "Port Security" command on a high-end Catalyst Switch to avoid this problem. These switch models include 4000, 4500, 5000, and 6500 series switches. Once the "Port Security" function is enabled on the port, you can specify the number of MAC addresses or specify the allowed MAC addresses to connect through this port. The command to enable this

Of course, this requires several tools to track, view, modify, and edit the software. Although there are many tools, I recommend the following combination: OllyDbg-Excellent tracing debugging software in Windows. It can be used for tracking, and software can be easily modified.

the intercepted packets through software, and then learn the specific IP address based on the information. Hide IP Although there are multiple methods for IP reconnaissance, there are also a variety of ways for users to Hide IP addresses. To deal with the most effective "packet analysis method", you can install "Norton Internet Security 2003" that can automatically remove the packet header IP information ". However, the use of "Norton Internet Securi

vehicle array. However, this cavalry is also crucial, because it takes time to form a vehicle array. Therefore, it is necessary to rely on this cavalry for reconnaissance. When marching, the cavalry will be alerted to detect the enemy in time. In the eye of heart, he and Yan felt that this ring-based vehicle fleet was completely a tactic to ban the military from being tailored to the masses at he Shuo.

This method is fast in speech recognition and has a high recognition rate. 2.3 Fingerprint Recognition The uneven skin on the inside of our palms, fingers, feet, and toes forms various patterns. The pattern, breakpoint, and intersection of these skins are different and unique. With this uniqueness, you can compare a person's fingerprint with his fingerprint to verify his real identity. General fingerprints are classified into the following major categories: Left Loop, Right Loop, t

radar, which can be classified by multiple methods: (1) the positioning method can be divided into: active radar, semi-active radar and passive radar. (2) the installation location can be divided into ground radar, onboard radar, aerial radar, and satellite radar. (3) Pulse Radar and continuous wave radar can be divided by radiation types. (4) The operating wavelength band can be divided into two types: radar at the worker wavelength, radar at the shard interval, radar at the worker wavelength,

protocolIt is one of the most important protocols in TCP/IP and provides a connectionless data packet transmission mechanism. Its main functions include addressing, route selection, segmentation, and assembly. 1. Disable IP Source Routing The IP protocol allows a host to specify the route through your network, rather than allowing network components to determine the optimal path. The valid application of this function is used to diagnose connection faults. However, this function is rarely used.

Because of the limitations of traditional financial software, providing leadership is usually limited static data, and when leaders want to compare from another angle, they need to re-provide the corresponding data. In this situation, many potential problems are hidden. While finding the cause of the problem requires more data to support, often the financial data is not enough to account for the problem and require the raw data of the business. Thus, the invisi
