20.500.12556/DKUM-55421 Odzivnost sistema ob napadih DoS System Responsiveness During DoS Attacks V magistrskem delu predstavimo odzivnost sistema pri različnih tipih napadov DoS. Različne tipe napadov DoS smo izbrali glede na pogostost njihovega pojavljanja v realnem svetu: poplavljanje SYN, poplavljanje UDP, poplavljanje ICMP in napad poplavljanje HTTP. Simulacija bo izvršena na spletnem procesu, ki bo pridobival podatke iz podatkovne baze. Med sinhrono komunikacijo uporabnikov po principu vprašanje-odgovor (ang. request-response) bo izveden določen tip napada DoS. Ta bo upočasnil delovanje procesa in posledično zmanjšal njegovo odzivnost, ki jo bomo izmerili v simuliranem okolju. Pridobljeni rezultati bodo prikazani na grafih, s katerimi si bomo pomagali pri analizi in ugotavljanju moči različnih tipov napadov DoS. In this thesis, we present responsiveness of systems with different types of DoS attacks. We selected different types of DoS attacks according to the frequency of their appearance in the real world: SYN flooding, UDP flooding, ICMP flooding and HTTP flooding attacks. The simulation is performed on web process, which acquires data from database. A specific type of DoS attack will be performed during users synchronous communication on the principle of request-response. This slows down the operating process and consequently reduce it’s response, that we measured in a simulated environment. Received results are shown on the charts, which helps us with analysis and determination of the strength of different types of DoS attacks. napadi DoS poplavljanje SYN poplavljanje UDP poplavljanje ICMP poplavljanje HTTP.
