Uchunguzi wa Kidijiti
[edit]Uchunguzi wa Kidijitali ni taaluma ya kisayansi inayohusisha urejeshaji, uchunguzi, ukaguzi na uchanganuzi wa data zinazopatikana katika vifaa vya kidijiti, mara nyingi kuhusiana na vifaa vya mkononi na uhalifu wa tarakilishi. Uchunguzi wa kidijiti unaweza kuwa na matumizi mengi lakini lengo lake kuu ni kukusanya, kuhifadhi, kuchanganua na kuwasilisha ushahidi ili kusaidia kuunga mkono au kupingana na nadharia kwa njia ambayo inakubalika mahakamani.
Kipengele cha kiufundi cha uchunguzi kimegawanywa katika matawi kadhaa madogo yanayohusiana na aina ya vifaa vya dijiti vinavyohusika: uchunguzi wa kompyuta,mtandao wa uchunguzi, uchambuzi wa data ya mahakama, uchunguzi wa kifaa cha rununu[1].Mchakato wa kawaida wa kiuchunguzi unajumuisha utekaji nyara, uchunguzi wa kimahakama (upatikanaji), na uchanganuzi wa vyombo vya habari vya kidijitali, ukifuatiwa na utoaji wa ripoti ya ushahidi uliokusanywa.
Pamoja na kutambua ushahidi wa moja kwa moja wa uhalifu, uchunguzi wa kidijitali unaweza kutumika kuhusisha ushahidi kwa washukiwa mahususi, kuthibitisha alibis au taarifa, kuamua nia, kutambua vyanzo (kwa mfano, katika kesi za hakimiliki), au kuthibitisha hati[2]Uchunguzi ni mpana zaidi katika wigo kuliko maeneo mengine ya uchanganuzi wa kitaalamu (ambapo lengo la kawaida ni kutoa majibu kwa msururu wa maswali rahisi), mara nyingi yanahusisha mistari changamano ya saa au dhahania.[3]
Uchunguzi wa kisayansi wa kidijitali
[edit]Uchunguzi wa kisayansi wa kidijitali kwa kawaida huwa na hatua tatu ambazo ni;
- upatikanaji au taswira ya maonyesho
- uchambuzi
- ripoti
tutazungumzia kila hatua kwa undani wake moja baada ya nyingine
Upatikanaji au taswira ya maonyesho
[edit]Upataji kwa kawaida hauhusishi kunasa picha ya kumbukumbu tete ya kompyuta (RAM) isipokuwa hii ifanywe kama sehemu ya uchunguzi wa majibu ya tukio.Kawaida kazi inahusisha kuunda nakala halisi ya kiwango cha sekta (au "duplicate ya uchunguzi") ya media, mara nyingi kwa kutumia kifaa cha kuzuia maandishi ili kuzuia urekebishaji wa asili.Walakini, ukuaji wa saizi ya media ya uhifadhi na maendeleo kama vile kompyuta ya wingu[4]imesababisha matumizi zaidi ya upataji wa 'moja kwa moja' ambapo nakala 'mantiki' ya data hupatikana badala ya picha kamili ya kifaa halisi cha kuhifadhi.[5]https://en.wikipedia.org/wiki/Digital_forensics#cite_note-dams-26 sahihi.
