00925njm 22002777a 4500 dc Iturbe, Mikel author Garitano, Iñaki author Etxezarreta, Xabier author Zurutuza, Urko author 2023 Kontrol industrialerako sistemak askotariko instalazio industrialetan erabiltzen dira, azpiegitura kritikoetan barne, segurtasun-eraso anitzen helburu nagusi bihurtuz. Sare industrialen konfigurazio eta topologia estatikoek, abantaila bat suposatzen dute erasotzaileentzat, erasoa egin aurretik gailu edo zerbitzu ahulak eskaneatzeko aukera ematen baitiete. Artikulu honek IP helbide, MAC helbide eta portu zenbakien aleatorizazioan oinarritutako errekonozimendu erasoen aurkako defentsa proaktibo bat aurkezten du. Lortutako informazioaren distortsioak erasotzaileek lortutako ezagutza gutxitzen du, sareko helbidean oinarritzen den edozein eraso oztopatuz. Sareko identifikatzaileen aleatorizazioa modu moldagarrian egiten da, sarean sartutako gainkarga minimizatuz eta komunikazioetan edozein errore eta latentzia saihestuz. Inplementazioa eta probak benetako ekipamendu industrialarekin gauzatu dira, aurkeztutako soluzioaren eraginkortasuna frogatuz. Industrial Control Systems are used in a wide variety of industrial facilities, including critical infrastructures, becoming the main target of multiple security attacks. Static networks configurations and topologies, which characterize Industrial Control Systems, represent an advantage for attackers, allowing them to scan for vulnerable devices or services before carrying out the attack. This paper presents a proactive network reconnaissance defense mechanism based on the temporal randomization of network IP addresses, MAC addresses and port numbers. The obtained information distortion minimizes the knowledge acquired by the attackers, hindering any attack that relies on network addressing. The temporal randomization of network attributes is performed in an adaptive way, minimizing the overhead introduced in the network and avoiding any error and latency in communications. The implementation as well as the tests have been carried out in a laboratory with real industrial equipment, demonstrating the effectiveness of the presented solution. 978-84-8438-865-4 https://katalogoa.mondragon.edu/janium-bin/janium_login_opac.pl?find&ficha_no=174473 https://hdl.handle.net/20.500.11984/6305 Zibersegurtasun industriala Software bidez definitutako sareak Erasoen defentsa proaktiboa Moving Target Defense Industrial cybersecurity Software defined networking Moving Target Defense Proactive intrusion response Latentziarik gabeko sareko identifikatzaileen aleatorizazioa kontrol industrialerako sistemetan proaktiboki errekonozimendu erasoak mitigatzeko
