The invasion examination is preliminary
Previous chapter of we talked about the Win2000 Server safe disposition, undergoes the careful disposition the Win2000 server to be possible to defend 90% above invasions and the seepage, but, on elephant time a chapter of conclusion I mentioned: The system safety is a continual process, along with the new crack's appearance and the server application's change, system's safe condition unceasingly is also changing; Simultaneously because the attack and defense is the contradictory entity, the road disappears the evil spirit length and the evil spirit disappears the Daoist priest also in the unceasing transformation, therefore, the wise system manager cannot guarantee that is providing the service the server long time not to invade absolutely.
Therefore, the security disposed the server is not the trouble-free service conclusion, on the contrary will actually be the long tasteless trouble-free service start, this article we will discuss the Win2000 server invasion examination initially the preliminary skill, hoped that could help you to maintain server's security for a long time.
In this article said what the invasion examination refers to the examination which using Win2000 Server is own function and system manager compiles the software/script which carries on, uses the firewall (Firewall) or invades the observation system (IDS) skill not in this article discussion scope.
Now supposes: We have a Win2000 Server server, and underwent the preliminary safe disposition (to be possible to refer to Win2000 about the safe disposition details the Server safe disposition to cross the threshold < one >), in this case, the majority of intruder will keep them out. (ha, my manager might go home to sleep) has been being slow, what I said was majority, was not completely, underwent the preliminary security disposition the server, although might defend (procedure which the overwhelming majority Script kid script race - will only use others to write to invade server's person), has run into the genuine master, collapsed at the first blow. Although said that the genuine master will not enter others' server casually, but was also unable to say for certain to have several bad conduct the evil faction master to have a liking for your server. (I really such fades? ) moreover, at crack's discovery and between the patch issue often some period of time's vacuum, any knew crack material the human may seize the opportunity to sneak, by now, the invasion examination technology appeared unusual important.
The invasion examination mainly carried on according to the application, provides the corresponding service to have the corresponding examination analysis system to carry on the protection, regarding the common main engine, mainly should pay attention to the following several aspects:
1st, invades the examination based on 80 ports
The WWW service was probably one of most common services, moreover, because this service facing the user community, the service current capacity and the order of complexity was very high, therefore were also most in view of this service's crack and the invasion skill. Regarding NT, IIS has been a part which the system manager compared has a headache (wishes one could to turn off 80 ports), but was good because of the IIS bringing journal function the efficient helper who might become the invasion examination from some kind of degree. The IIS bringing journal file default deposits under the System32/LogFiles table of contents, generally is according to 24 hour trundle, may carry on the detailed disposition in the IIS supervisor to it. (how to match me specifically, no matter you, but you, if detailed record, turns head does not look up intruder's IP to be possible not to need to cry)
