Ingqumbo yayo inokwenkqonkqo kwokhuseleko lwengcaciso ukuba ezininzi iimpawu ezisebenzisa iikhompyutheni zilula okanye zisebenza kakuhle kwaye izixhobo ezisetyenziselwa ukukhusela nokukhusela umnxibelelwano zingasetyenziselwa ukuxhaphaza kwaye zidibanise iikhomputha kunye namanethiwekhi afanayo. Le yimeko ngepakethi yokufutha.
I- packet sniffer , ngamanye amaxesha ebizwa ngokuba ngumboniso wenethiwekhi okanye i-analyzer network, ingasetyenziselwa ngokusemthethweni ngethungelwano okanye umphathi wenkqubo ukujonga nokujongana neengxaki zentengiso. Ukusebenzisa ulwazi olufakwe yi-packet sniffer umlawuli angakwazi ukubona iipakethe eziphosakeleyo kwaye asebenzise idatha ukuze abone iipotenecks kwaye ancede ukugcina ukuhanjiswa kwedatha efanelekileyo.
Ngendlela yayo elula ipakethe sniffer imane ithatha zonke iipakethi zedata ezidlulayo kwi-interface yomnatha. Ngokuqhelekileyo, i-packet sniffer yayiza kubamba iipakethi ezazijoliswe kumatshini. Nangona kunjalo, ukuba ifakwe kwindlela yokuziphatha, i-packet sniffer nayo iyakwazi ukuthatha zonke iipakethi eziwela inethiwekhi ngaphandle kokuya kuyo.
Ngokubeka ipakethi yefayile kwi-intanethi kwimo ekhohlakeleyo , umntu onobungozi onokuthi angabamba aze ahlalutye yonke inethiwekhi yendlela. Kwinkonzo enikeziweyo, igama lomsebenzisi kunye nolwazi lwephasiwedi ngokubanzi ludluliselwa kwisicatshulwa esicacileyo esithetha ukuba ulwazi luya kubukwa ngokuhlaziya iipakethi ezihanjiswayo.
I-packet sniffer iyakuthatha kuphela ulwazi lwepakethe ngaphakathi kwiphantsi. Ngoko ke, akunakwenzeka ukuba umhlaseli onobungozi abeke ipakethi ye-packet kwi-home network ye- ISP kwaye athathe inethiwekhi yendlela yokunxibelelanisa esuka ngaphakathi kwintanethi yakho yenkampani (nangona kukho iindlela ezikhoyo kwiinkonzo ezingaphezulu okanye ngaphantsi "zokugxila" ezisebenza kwinethiwekhi yakho yangaphakathi ukuya ukwenza ipakethi yokufuduza kwindawo ekude). Ukuze wenze njalo, i-packet sniffer kufuneka isebenze kwikhompyutha ephakathi kwintanethi yenkampani kunye. Nangona kunjalo, ukuba umatshini omnye kwi-intanethi yangaphakathi ehlaselwa yiTrojan okanye enye ukuphulwa kwezokukhusela, umntu ongenakho ukuqhuba i-packet sniffer esuka kuloo matshini kwaye asebenzise ulwazi lomsebenzisi kunye nephasiwedi ebanjwe ukunciphisa abanye oomatshini kwinethiwekhi.
Ukufumanisa iipakethe eziphambili kwi-intanethi akuyona into elula. Ngokweyona ndlela i-packet sniffer ayihambelani. Uthabatha nje iipakethi ezihamba kwi-interface yomnatha ekuqwalaseleni. Oko kuthetha ukuba akukho mqondiso okanye i-erratic tracking look for which would identify a machine that runs a packet sniffer. Kukho iindlela zokuchonga izixhobo zokunxibelelana kwintanethi kwi-intanethi yakho esebenza kwindlela yokuziphatha kwaye le nto ingasetyenziselwa njengendlela yokufumana iipakethe eziphambili.
Ukuba ungomnye wabantu abalungileyo kwaye kufuneka ugcine kwaye ulonge inethwekhi, ndincoma ukuba uqhelane nabagadi beenethwekhi okanye iipakethi ezinjenge-Ethereal. Funda ukuba uluphi uhlobo lwengcaciso oluya kuqondwa kwi-data efunyenweyo kwaye ungayisebenzisa njani ukugcina inethiwekhi yakho isebenza kakuhle. Kodwa, uqaphele ukuba abasebenzisi kwi-intanethi banokuqhuba iipakethe eziphambili, okanye bazama ukufuna umdla okanye ngenjongo enobungozi, kwaye kufuneka wenze okusemandleni akho ukuqinisekisa ukuba oku kwenzekayo.
