20.500.12556/DKUM-63831 Pregled in regeneracija podatkov z rabljenih računalniških trdih diskov specialistično delo podiplomskega študija informacijska varnost Examination and regeneration of data from used computer hard drives Osebni računalniki tudi v 21. stoletju ostajajajo pomemben dejavnik pri zbiranju, obdelavi in hranjenju podatkov. Uporabljajo se v zasebnih in državnih podjetjih, v raziskovalnih ustanovah, v državni upravi, v ekonomsko razvitih delih sveta so našli pot tudi v že skoraj vsak dom in Slovenija pri tem ni izjema. Popolne varnosti ni in nivo nadzora nad podatki na našem računalniku je odvisen od varnostnih ukrepov vsakega uporabnika posebej. Vprašanje, ki se ob tem postavlja, pa je, kako uporabnik poskrbi za podatke, ko spominski medij zamenja ali odvrže. Ali se zaveda možnosti zlorabe podatkov in ali je sploh seznanjen z možnostjo dokončnega izbrisa podatkov? Izbris podatkov iz Koša namreč ni dovolj in podatke je mogoče priklicati nazaj. Da bi preverili varnostno kulturo uporabnikov, smo za to nalogo zbrali večje število rabljenih odvrženih trdih diskov. Njihovo vsebino smo pregledali z enotno sistematizacijo dela, za obnovitev izbrisanih podatkov pa izbrali programsko opremo, ki je brezplačna in prosto dostopna na spletu. Želeli smo namreč preveriti, ali je brez visokotehnološke opreme in finančnih vložkov obnova podatkov z odvrženih diskov mogoča do te mere, da lahko predstavlja grožnjo uporabnikom z nizko varnostno kulturo. V nalogi opisujemo tudi zgradbo in delovanje trdega diska in obravnavamo možnosti in težave pri revitalizaciji podatkov. Ugotovili smo, da večina uporabnikov podatkov s svojih diskovnih medijev ne zbriše, preden jih odvrže, in da je v večini primerov najdene podatke mogoče povezati z uporabnikom. In the 21st century personal computers have become devices where personal data is being collected, processed, and stored. Computers are being used everywhere, at private and state enterprises, research institutions, state administration, at almost every home, etc. In the economically developed parts of the world computers have found their way into almost every home and Slovenia is no exception. Unfortunately there is no such thing as absolute security, and the level of control over the data that reside on the computer’s hard drive depends solely on the individual user’s information security awareness. The very important information security question is, what do users actually do with their data when their hard drives are being replaced or discarded? Are they actually aware of the potential misuse of their private information and do they know how to permanently and irrevocably delete the data from the hard drives? Deleting the data and even removing the data from the Recycle Bin is insufficient, namely the data can be easily and completely recovered. One of the goals of this work is to test the security awareness of the unknown users. To this end we have collected a number of randomly chosen discarded hard drives. Initially the methodology to systematically test the collected hard drives was set. To restore the deleted or corrupt data the easy accessible and free software was selected. We wanted to demonstrate that the data restoration is possible even without possession of expensive high-tech software and hardware equipment, and even without deeper knowledge of the hard drive technology and operation. First the brief introduction is given on the history of development, structure, and operation of hard drives. The most common problems in the process of revitalization of data are introduced. The results of the presented work clearly show that the majority of computer owners do not erase data from their hard drives before discarding them. In most cases information found on the disks also contains easy accessible owner’s personal data. informacijska varnost trdi diski obnovitev podatkov revitalizacija podatkov osebni podatki specialistične naloge information security hard drive data recovery electronic waste data recovery software personal data true true false P.
