Leyo fayili owacabanga ukuthi isusiwe sakho kungenzeka ukuthi ikhona kuDrayivu yakho
Uma usula ifayela kukhompyutheni yakho, ukuyeka kokuqala ngokuvamile kuvolda yakho "yokubuyisela kabusha" noma "udoti" wesistimu yakho yokusebenza. Ubekwe endaweni yesikhumba yesikhashana uma kwenzeka ushintshe ingqondo yakho futhi ufuna ukuthola kamuva ifayela .
Iningi labantu licabanga ukuthi uma bathatha isinyathelo esengeziwe sokuthi "unomphela" basuse ifayela kusuka ebhodini lokuvuselela kabusha, manje sebesuka ngokusemthethweni kwi-hard drive yabo, futhi badlulile iphuzu lokubuyiselwa.
Abantu abaningi abangazi ukuthi kungenzeka ukuthi kungenzeka ukuthi idatha evuselelekayo ingase ihlale ku-hard drive yabo ngisho nangemva kokuthi isuse ifayela kusuka endaweni yokuvuselela / udoti.
Uma Ngisusa iFayili, Kungani Kungenzeka Iphinde Ibuyiswe?
Ngokusho kwe-Wikipedia, i-Data Remanence "ukumelela kokuhlala kwedatha yedijithali ehlala ngisho nangemva kokuzama ukukhipha noma ukusula idatha".
Uma ususa ifayela, isistimu yokusebenza ingamane isuse irekhodi le-pointer efayeleni, okwenza lifinyeleleke ngamathuluzi wokuphequlula amafayela wesistimu yokusebenza. Lokhu akusho ukuthi idatha yangempela isusiwe ku-disk drive.
Idatha Yokubikezela Amathuluzi Ingase Iseze Ukuletha Amafayela Emuva Kulabafileyo
Abaningi bezobuchwepheshe be-forensics baphila ngokuvusa amafayela abantu (kubandakanya nezigebengu) okungenzeka bacabanga ukuthi babhujiswe. Basebenzisa isofthiwe yokutakula ekhethekile ehlola i-disk media ngemininingwane ebonakalayo. Lawa mathuluzi akhethekile adalwe ukungazibali izinkinga zendabuko ezibekwa uhlelo lokusebenza kanye nesistimu yefayela. Amathuluzi afuna izinhlokweni zamafayela asetshenziswe izinhlelo zokusebenza ze-software njenge-Excel, iZwi nabanye ukuze banqume ukuthi yiluphi uhlobo lwedatha olungatholakala futhi.
Lokho amathuluzi angakwazi ukululama empeleni kuncike ezintweni eziningana, njengokuthi noma ngabe idatha yefayili isasebenza yini, ibhalwe ngaphezulu, ibhalwe ngekhodi, njll.
Ngokumangalisa ngokwanele, ngezinye izikhathi kungenzeka ngisho nokubuyisela idatha kudrayivu obekucatshangwa ukuthi ifomathiwe. Uma "ifomethi esheshayo" isetshenzisiwe, khona-ke kuphela iThebula lokwabiwa kwefayela (FAT) kungenzeka lisusiwe, mhlawumbe kuvumela ukutholakala kwamafayela okuzocatshangwa ukuthi asusiwe ngesikhathi senqubo yokufometha.
Izigebengu Zithenga Amashayeli Asebenza Kanzima
Abakwa-Cybercriminals bayazi ukuthi idatha ivame ukubuyiselwa kwizinkinobho ezinzima eziye zaxoshwa ngaphandle. Bangase bafune ukudayiswa kwegceke, amasheya e-Ebay, izikhangiso ze-Craigslist, njll, kumakhompyutha asetshenzisiwe enethemba lokusebenzisa amathuluzi angaphambili ukuze alulame idatha yomuntu siqu ngaphandle kwezingcingo ezilahlayo. Bangasebenzisa lolu lwazi ngenhloso yokwebiwa kwezazisi, ukuthungatha, ukuphanga, njll.
Ungaqiniseka Kanjani Ifayela Lakho Lehlelekile?
Ngaphambi kokuthi uthengise, noma ulahle ikhompyutha endala, kungcono ukususa nokugcina kuyinkimbinkimbi yedrayivu. Ungasula i-hard drive ngokuphelele nge-disk-grade disk ukusula izinsizakalo, kodwa awukwazi ngokuphelele ukuthi ubuchwepheshe obusha obungaphambili ngeke buphume esikhathini esizayo esingasemuva, okuvumela ukutholakala kwedatha okungakafinyeleki ngaphambili usebenzisa izindlela zamanje. Ngenxa yalesi sizathu, kungcono kakhulu ukuthi ungathengisi i-hard drive yakho yakudala nekhompyutha yakho endala.
Izinto ezingasiza ukuqeda lelo fayela elifakiwe ngokuhle:
Ukuhlukunyezwa
Izinsiza eziningi zokutakula ifayela zixwayisa abasebenzisi abahlukumeza i -hard drive banganciphisa izinkinga zokukwazi ukubuyisela amafayela ngoba inqubo yokuzikhukhumeza ngokwayo ihlanganisa idatha futhi ingase ibhale ngaphezulu izindawo lapho idatha esusiwe ikhona khona. Nakuba kungasiza, ukumane ukuphazamisa idrayivu yakho ngeke kuqinisekiswe ukuthi idatha ayitholakali ngakho akufanele uthembele kuyo njengendlela yokususa.
Ukubethela Idatha
Amathuluzi wokuhlaziya angakwazi ukuchofoza idatha, kodwa uma ukubethela kunamandla ngokwanele ke amathuluzi angeke akwazi ukuvusa okuqukethwe kwefayela. Cabanga ngokuvula isici sokufaka isikhala sakho se-disk ukuze usebenzise leli lungelo. Futhi cabanga ukusebenzisa amathuluzi afana ne- TrueCrypt ekubetheni amafayela akho azwelayo.
Zama ukubuyiswa kwefayela elincane le-DIY Kukho Yakho
Uma ufuna ukubona ukuthi yimaphi amafayela angase alulameke ohlelweni lwakho siqu, kungani ungazami ku-forensics yakho encane ye-Do-it-Yourself bese uzama ukubona ukuthi ungabuyiselwa kanjani usebenzisa inguqulo yamahhala ye-thuluzi yokutakula ifayela? Ungathola kabanzi mayelana nendlela yokuthola amafayela asusiwe ku-athikili yethu: Ifayela le-DIY Forensics .
