User Datagram Protocol The second level - the so-called "main computer" that is, machines that receive the signal of an attack with a control Console and convey it to the agents, "zombies." Depending on the magnitude of the attack, one management console can account for up to several hundred hosts. In the third, the grass-roots level there are agents - is "Zombie" computers, which make its requests attacking the target node. Cowan has many thoughts on the issue. In contrast to the main computer and control consoles, the number of "zombie" is constantly changing as computer owners use anti-virus means administrators disable the infected segments of WAN access, etc., forcing criminals to spread viruses continue to receive new bot system. And follow this structure in the reverse direction is almost impossible. The maximum that can identify the defensive player, so it is the address of the agent. And at best, will be known the main computer. But, and computers 'zombies', and the main computers are also affected in this situation. That's because this structure is almost impossible to keep track of the node address, which organized the attack. DDoS danger lies in the fact that the attacker is almost no need to possess any special knowledge and resources. Programs for the attacks, and information technology is freely available on the Internet. But initially this kind of software created exclusively for "peaceful" purposes. It was used for experiments on the capacity of networks and their resilience to external loads. To date, there are the following types of DDoS-attacks: UDP flood - to send to the address of the target set of packets UDP (User Datagram Protocol). This method used in earlier attacks and is now considered the least dangerous. Programs that use this type of attack is easily detected, since the exchange of the...

Reboot your computer during this reboot, still does not start WINDOWS push the button 'Delete', to get into your computer's BIOS (BIOS - it's computer system, the set of verbal symbols on a blue or gray background). Our task make computer first load CD / DVD-drive, and then everything else, so we do next - go to the tab Boot (she may have slightly different names, read on and you will understand). In this tab we need to rearrange the boot order so that the computer in the first place was a drive, just put the drive in the first place, and the second, what was on the ground and everything. Puts the disc with WINDOWS. Cowan Financial has compatible beliefs. Then save the settings BIOS (and save vyberaem exit, and then the BIOS will automatically save and restart the computer).
