Namuhla, ama-USB flash drive asephenduke amathuluzi abalulekile. Kungakhathaliseki ukuthi ungumfundi ophethe amanothi noma uchwepheshe onamafayela abalulekile, lawa madivayisi asindisa impilo ngenxa yokusebenza kwawo kanye nomthamo wawo wokugcina . Kodwa-ke, lokho kulula kuwenza abe yisisulu esilula; njengoba emancane kakhulu, kulula kakhulu ukuwalahla noma kuphi noma, okubi nakakhulu, awele ezandleni ezingafanele.
Inkinga akuyona nje umuntu othola izithombe noma amadokhumenti akho, kodwa ingozi yangempela yokwebiwa kobunikazi kanye nokusabalala kwe-malware. Uma singaqapheli, idrayivu ye-USB ingasuka ekubeni ithuluzi eliwusizo iye ekubeni umnyango ovulekile wokuthi umgebengu afinyelele ikhompyutha yethu. Yingakho kubalulekile ukwazi ukuthi ungawavikela kanjani amadivayisi akho nazo zonke izendlalelo zokuphepha ezitholakalayo ukuze idatha yethu ingashiywa ivulekele ingozi.
Ukuvikelwa kwedatha ngokubethela
Uma uphatha ulwazi olubucayi kakhulu, njengezitatimende zasebhange noma amadokhumenti omazisi, ukuthembela enhlanhleni akwanele. Inketho eqinile kakhulu ukubethela, okwenza idatha ingafundeki kunoma ubani ongenalo ukhiye. Kunezindlela ezahlukahlukene zokufeza lokhu, kuye ngohlelo lwakho lokusebenza.
Kulabo abafuna ikhambi elihlanganisa amapulatifomu amaningi, i-VeraCrypt iyithuluzi elihle kakhulu elitholakala kwiWindows, macOS, kanye neLinux. Le nqubo ihilela ukudala ivolumu ebethelwe ngokukhetha i-USB partition bese unikeza iphasiwedi eqinile. Kodwa-ke, kubalulekile ukuqaphela ukuthi le nqubo isula idatha ekhona, ngakho-ke kungcono ukuyenza ngaphambi kokukopisha noma yiluphi ulwazi. Ukuze ufinyelele amafayela ngemva kwalokho, mane ufake idrayivu ngephasiwedi efanele.
Uma ungumsebenzisi we-Windows onenguqulo ye-Pro noma ye-Enterprise, unokufinyelela ku- BitLocker To Go . Lesi sici esakhelwe ngaphakathi sikuvumela ukuthi ubethele idrayivu yakho ngokuchofoza kwesokudla kudivayisi futhi uvumele ukuvikelwa kwedatha. Ukuze uqonde kangcono izinzuzo zayo, ungabheka lokhu kuqhathanisa phakathi kwe-BitLocker nokubethela kwedivayisi . Kubalulekile ukwenza isipele sesitifiketi sakho sokubethela, ngoba uma ulahlekelwa ukhiye, ngisho nochwepheshe othuthuke kakhulu ngeke akwazi ukubuyisa amafayela akho.
Kulabo abafuna ukuphepha okukhulu, kukhona ukubethela kwehadiwe . Lawa madivayisi ememori afika nekhiphedi ebonakalayo ehlanganisiwe yokufaka i-PIN. Kuyindlela ephephile kakhulu, yize inengozi: uma ukhohlwa ikhodi noma ulahlekelwa ukhiye ongokoqobo, ulwazi lulahleka unomphela. Kunconywa kakhulu ukuthi uhlale ugcina ikhophi yasenqolobaneni kwenye indawo ephephile.
Ukulawula ukubhala kanye nokuvikela ukusula
Ngezinye izikhathi asidingi ukubethela kwebanga lezempi, kodwa simane nje sivimbele othile ekususeni ifayela ngephutha noma umsebenzisi ongagunyaziwe ekushintsheni okuqukethwe kwalo. Ku-Windows 10, singalungisa izimvume zokuphepha. Ngokufometha idrayivu ngesistimu yefayela le-NTFS , singafinyelela kuthebhu Yokuphepha, sihlele izimvume, bese sikhetha inketho yokwenqaba ukufinyelela kokubhala kwabo bonke abasebenzisi.
Ukuze kube nendlela enembile kakhudlwana, singakha ifolda ethile futhi sikhubaze ifa lemvume . Lokhu kuvumela noma ubani ukuthi afunde okuqukethwe kodwa kuvimbela noma ubani ukuthi asuse noma ahlele amafayela angaphakathi. Lokhu kulungele ukusabalalisa izinto ezifana namavidiyo omculo noma izethulo, kuvimbela umsebenzisi ojwayelekile ukuthi azisebenzise kabi, yize kungavimbeli umuntu onolwazi oluthuthukile ukuthi afomethe yonke idrayivu.
Endabeni ye-macOS, isimo sihlukile njengoba kungekho izici zokuvikela ukubhala zomdabu ezifanayo. Icebo eliwusizo kakhulu ukufometha idrayivu njenge-NTFS ; njengoba i-Apple ingavumeli ukubhala komdabu kule fomethi, idrayivu izoba kwimodi yokufunda kuphela yanoma iyiphi i-Mac.
Ukuvikela amagciwane kanye ne-malware
Ama-USB drive ayi-vector ethandwa kakhulu ngama-virus amaningi, ikakhulukazi i-shortcut virus edumile. Le malware ifihla amafolda okuqala futhi idale ama-shortcut okuthi, uma esetshenziswa, athelele ikhompyutha. Ukuze kulwiwe nalokhu, isu eliphumelelayo ukudala ifayela elivikelwe le-autorun.inf . Kunezikripthi (amafayela e-.bat) ezingagoma i-USB drive, zidale ifayela lesistimu elifihliwe, elifundwayo kuphela elivimbela igciwane ukuthi libhale i-executable yalo.
Ngaphezu kokugoma, ukwamukela imikhuba enempilo kubalulekile. Ukugwema ukuxhuma amadivayisi okugcina angaziwa kungumthetho wegolide, njengoba singeke sazi ukuthi aqukethe yiphi i-malware. Ngakho-ke, kubalulekile ukwazi ukuthi ungayivikela kanjani ikhompyutha yakho kuma-drive e-USB anonya . Ngokufanayo, ukugcina isofthiwe yakho yokulwa namagciwane ibuyekeziwe nokwenza ukuskena okujulile njalo uma uxhuma idivayisi yangaphandle kuyindlela engcono kakhulu yokuzivikela ekuthelelekeni okungaxhunyiwe ku-inthanethi.
Amathiphu okwandisa isikhathi sokuphila kwedivayisi
Ngale kokuphepha kwe-cyber, kukhona ukuphepha okungokoqobo. Ukuze uvimbele idrayivu ye-USB ukuthi ingaphumeleli ngaphambi kwesikhathi, kubalulekile ukusebenzisa njalo ukususwa kwesistimu yokusebenza okuphephile , ngaleyo ndlela ugweme ukonakala kwedatha. Kunconywa futhi ukuthi usebenzise izinyathelo zokuphepha ezingokoqobo ezibalulekile ukuvikela ihadiwe yakho , njengokusebenzisa isivalo sokuvikela ukuvimbela uthuli noma umswakama ekulimazeni izixhumi zangaphakathi.
Akufanele siphoqelele i-memory stick lapho siyifaka echwebeni, futhi kuyalulekwa ukuthi singashiyi idivayisi ixhunywe unomphela kwi-PC, njengoba ukuguguleka kukagesi kunganciphisa isikhathi sayo sokuphila. Okokugcina, ukwenza ifomethi njalo kusiza ukususa amaphutha ohlelweni lwefayela futhi kugcine idrayivu isesimweni esihle.
Ukugcina ukuphepha kwedatha yethu kuhilela ukuhlanganisa ukusetshenziswa kwesofthiwe yokubethela, ukuphathwa okuhlakaniphile kwezimvume zokubhala, kanye nokuhlanzeka okuqinile kwedijithali ngokumelene namagciwane, ngaphezu kokunakekelwa ngokomzimba kwehadiwe ukuqinisekisa ukuthi ulwazi luhlala lutholakala futhi luvikelwe.
