20.500.12556/DKUM-19360 ANALIZA IZPOSTAVLJENOSTI VARNE LUPINE NA NAPADE Z GROBO SILO ANALYSIS OF SECURE SHELL EXPOSURE TO BRUTE FORCE ATTACKS Raziskava obravnava analizo izpostavljenosti varne lupine na napade z grobo silo. V javnem naslovnem prostoru medmrežja smo postavili limanico z nizko stopnjo interakcije, ki simulira delovanje strežnika varne lupine. V eksperimentalnem delu diplomske naloge je bila izvedena analiza poskusov prijave z uporabo grobe sile v obdobju desetih tednov. Ugotovili smo, da je bilo narejeno izjemno veliko število poskusov prijave na sistem. Opravljene meritve so pokazale karakteristike napadov. Zbrani podatki nam omogočajo vzpostavitev varnostnih mehanizmov, ki pomagajo pri preprečevanju napadov z uporabo grobe sile. The research deals with analysis of secure shell exposure to brute force attacks. We used the public internet address space to set up a honeypot, which simulates the operation of a secure shell server. In the experimental part of the thesis we have performed an analysis of login attempts using brute force in a period of ten weeks. We found out that an exceptional number of login attempts was made. The measurements we have carried out showed the characteristics of the attacks. The data gathered allows us to establish security mechanisms that help prevent brute force attacks.
