چکیده (انگلیسی):

A Denial-of-Service (DoS) attack, a menace to the availability of resources and service to the intended user, is
usually by augmenting the traffic in the communication medium. These attacks originate in either ways,
internal or external to a network with the aim to suspend the legitimate user from getting his/her service. The
DoS attacks have been countered through various approaches, yet this problem remains stable in field. The
traceback mechanisms of the attacker necessitate a large amount of valuable information which is usually
hidden by the attacker or not documented in the network. Moreover the network has strict constraints over the
usage of memory resources by the nodes and routers, equivalent to an empty memory nature. The amount of
data reasonably required for computation would increase the processing delay which is usually unexpected.
The counter measures proposed tried to detect the network under attack or to track the attacker with some
degree of information available. Nowadays these attacks have evolved to break out from all those detection
approaches with greater immunity to not reveal their identity. This study works with the physical zone
addresses to detect and traceback the identity of the attacker. The packet sent from the attacker carries merely
the part of its identity. Yet the Provincial Assessment Attributes (PAA) possesses the geographical locality
aspects in terms of Continent Code, Country Code, State Codes and the Area Codes along with its IP address.
Accepting the factor that IP is spoofed in most cases, the routers in the path are still able to keep track of these
PAA prospects irrespective of the faked IP. Hence this mechanism could be implemented with minimal
computation, leading to the attacker with considerable and fruitful results in identifying the same. Besides, this
method takes deep care to authenticate and not to affect the traffic of legitimate users.
