Using the web or another research tool, search for alternative means of defending against either general dos attacks or a particular type of dosattack. this should be any defense other than the ones already mentioned in chapter 4. write one-page summary regarding your found defense techniques (at least two techniques). you are required to cite all your references that you used to write the summary. your answer should include the following information for each of the alternative defending approaches:

Answer and Explanation:

DOS attacks refer to Denial of Service attack. It is a sort of digital attack where a programmer hacks the system of a framework and makes it inaccessible for the clients which results in intruding on the internet providers of the machine.  

At the end of the day, access to online administrations is denied for the client. Any sort of system administration can be upset by DOS assaults be it either bank site or an online business site.

Following is one of the defense techniques against DOS attacks:

Using Routers and Firewalls - As switches have rate constraining and access control capacities, so they can be set up in a legitimate manner to stop basic ping assaults by permeating unessential conventions and can likewise stop invalid IP addresses. In any case, the main hindrance for utilizing switches is that they are usually ineffective against an increasingly advanced parodied assault and application-level assaults utilizing substantial IP addresses. Presently here comes the job of firewalls. Firewalls can ensure the system by dismissing all the traffic landing from aggressor's end. This insurance by firewalls depends on basic principles dependent on conventions, ports or the starting IP addresses.  

Be that as it may, it is difficult to hinder some mind boggling assaults by these straightforward standards. For instance, if there is a progressing assault on port 80 (web administration), it is beyond the realm of imagination to expect to drop all approaching traffic on this port in light of the fact that doing so will keep the server from serving genuine traffic.  

One detriment of firewall is that Firewalls can close down a particular stream related with an assault, however like switches, they can't perform hostile to ridiculing.
