Sniffer password, network. Sniffer - ntoni na?

Abasebenzisi abaninzi lweenkqubo zeekhompyutha weva into enje njenge "sniffer". Ntoni na, ke, ukuba ngqondweni ngokupheleleyo asingabo bonke. Ngaphezu koko, namhlanje kusenokwenzeka ukuba anikezele isangqa abambalwa kakhulu abantu abayaziyo ukuba usebenzise inkqubo enjalo kwaye 'nentsimbi' izixhobo njani yaye phi. Makhe zama ukulungisa oko nto.

Sniffer: ntoni na?

Makhe siqale kwenkcazo kota. Ukuze siqonde kakuhle lo mbandela, kufanele kube lula ukuqala ukuguqulela igama elithi "sniffer". Yintoni na? Le kukuguqulela IsiNgesi iingqiqo sniffer yi "Sniffer".

Ngamafutshane, le program okanye izixhobo ekwaziyo ezicingisisiweyo ezisekelwe ekuhleleni nasephicotheni wezothutho ngohlobo ipakethe ezosulela okanye wafumana data kwi network ukufumana ulwazi oludingayo, nokuba uthungelwano lwangaphandle IP-iidilesi, password asongiweyo okanye idatha eyimfihlo. Ngokwabo sniffers zingasetyenziswa ukwenzakalisa nokuzuza.

Eyona eziphambili ze sniffers

Ke iintlobo eziphambili sniffers, kusenokuba kungabi kwisoftwe efakwe kwi computer, okanye ezenziwe ngohlobo ye applet online.

Ngokufuthi ungafumana sniffers ngohlobo "intsimbi" izixhobo okanye izinto ezidibanisa kunye software, kunye neempawu zomzimba. Ngako oko, le sniffers engundoqo yokuhlela zibandakanya ezi ndidi zilandelayo:

• software;
• hardware;
• firmware;
• izakhi intanethi.

Xa ulwahlulohlulo Prayimari sinokuba bungabonakala buhlolwe ngokubanzi kunye nolwalathiso ngokwahlukana. Umzekelo, iintlobo zixhaphakileyo ezifana agqithisiweyo sniffer, umsebenzi wayo ophambili kukuba athabathe iipakethi data codes evulekileyo okanye ofihliweyo lokufikelela nakoluphi ulwazi. Kukho sniffers eziquka ukubala kuphela terminal IP-iidilesi ezithile ukwenzela ukufikelela computer umsebenzisi kwaye zigcinwe inkcazelo yayo.

Zisebenza njani?

Technology zenethiwekhi traffic kusebenza kuphela based networks kwiiprothokholi zeTCP / IP kwaye yaphunyezwa uqhagamshelwano nge amakhadi womnatha Ethernet. iinethiwekhi ze-wireless nazo zihlalutywe, ekuqaleni kunjalo kuba nkqubo kukho unxibelelwaniso ngeengcingo (ukuba umzila, ngomzi kwi laptop okanye desktop PC).

ukudluliselwa Data kwi network ayikho unit ebalulekileyo, yaye nge kwisahlulo yalo iipakethi kunye namacandelo standard, apho, xa efumana icala ukwamkelwa ziye zidityaniswe zibe iyunithi enye. Inkqubo-sniffer uyakwazi ukulandelela yonke imijelo zothumelo kunokwenzeka of kwilungu ngalinye, kwaye ngexesha of transfer (ukudlulisela) iipakethi ngendlela engakhuselekanga ukuze izixhobo ezinxulumene kwinethiwekhi (imizila, neenafu, itshintshela, iikhompyutha okanye izixhobo mobile) livelise idatha efanelekileyo, nto leyo inokuba liqulathe passwords efanayo. Ngenxa yoko, waphula lokugqitha uba ayibobuchule eqhelekileyo, ingakumbi ukuba akukho kwi khowudi.

Kodwa xa usebenzisa ubuchwepheshe igama encryption phambili, oko enokusasazwa kunye iqhosha elihambelanayo. Ukuba ivuliwe isitshixo ukuze ufumane elula password. Ukuba isitshixo ngokufihlisa, ohlaselayo lula ukusebenzisa nayiphi software-idikhowuda, nto leyo ekugqibeleni nayo kukhokelela ng data.

Apho ukusebenzisa inethiwekhi sniffer?

Field yokusebenzisa sniffers yinto eyahlukileyo. Andiqondi ukuba sniffer lula in Russian yeyona ndlela kuphela imigewu ngokuzama ukwenza uphazamiseko engagunyaziswanga kwi kwenethiwekhi ukuze ufumane ezinye iinkcukacha ezibalulekileyo.

Kunye sniffers nempumelelo ngokulinganayo zinokusetyenziswa ngababoneleli ezisekelwe kuhlalutyo lwabo yezithuthi data wavelisa abasebenzisi bayo, ekukhuthazeni ukhuseleko lweenkqubo zekhompyutha. Nangona loo izixhobo nezicelo ekuthethwa antisnifferami, enyanisweni ibe yeyona sniffers ezininzi eziqhelekileyo uthanda ukusebenza kwicala elahlukileyo.

Kakade ke, abasebenzisi izenzo ezinjalo kungekho bani azisa umboneleli, kwaye angaqondakali kulo. umsebenzisi yabucala akunakwenzeka ukuba bakwazi ukuthatha ngokuzimeleyo naziphi zokumelana. Kwaye kaninzi umboneleli analysis traffic kubaluleke kakhulu kuba oko kunokuthintela amalinge ukuba aphazamise umsebenzi kothungelwano bangaphandle, zokuhlalutya ukufikelela ukuze adlulisele iipakethi, unako ukulandela olungagunyaziswanga ukufikelela kubo ubuncinane ngokwesiseko peripherals efanayo IP-iidilesi, ezama ukuba ganga ngoku inxalenye ngobulili. Kodwa ngumzekelo elula kakhulu, ngenxa yokuba bonke obu bugcisa nelunzima kakhulu uninzi lwawo.

Ukumisela phambi sniffer

Xa ushiya bucala into enjalo njenge "sniffer". Ntoni na, yinto ecacileyo encinane ngoku kubona oko ngezizathu unako ukuchaza "wiretap" sniffer neyakhe.

Ukuba inkqubo yekhompyutha KULUNGILE, kwaye uthungelwano okanye Internet uxhulumaniso isebenza kakuhle, uphawu lokuqala ngoncedo ngaphandle kukunciphisa izinga ipakethe, xa kuthelekiswa loo lowu yi le ISP. Kwiinkqubo-based Windows ebhanileni kuthetha ukumisela isantya umsebenzisi komndilili ngenkankulu naxa uthungelwano ubume menu umnxeba ngokunqakraza kwi icon ukudibanisa. Apha ungakhankanya kuphela inani iipakethi wathumela ezifunyenweyo.

Ngokufanayo, ukusebenza kwi "umphathi umsebenzi" bonisa ulwazi olufunayo ngokupheleleyo, ukuba isantya ekunciphiseni efanayo kunokunxulunyaniswa kunye neentsilelo lwemvelaphi yokufumana yenziwa ngawo. Kungcono kakhulu ukusebenzisa izixhobo ezikhethekileyo, analyzers, leyo, ngasendleleni, kwaye umsebenzi umgaqo sniffer. Inye kuphela udinga ukuhlawula ingqalelo, oku kuphela kukuba olu hlobo lwenkqubo emva kokufakwa kunokubangela iimpazamo ezithe zenzeka ngenxa yempixano kunye firewalls (a firewall eyakhelwe-Windows okanye "intsimbi" uhlobo software and hardware wesithathu). Ngenxa yoko, ngelo xesha uhlahlelo okucoca, kungakuhle ukuba ukhubaze.

isiphelo

Apha, okunene, yaye yonke into yokwenza loo nto njenge "sniffer". Yintoni na ngokwemiqathango lokubulala izixhobo okanye ukhuselo, umgaqo, kufuneka icace. Kuhleli ukuba ukongeza amagama ambalwa malunga applets online. Bathi nje ukuba ubukhulu becala isetyenziswa imigewu ukuba afumane i-IP-idilesi nexhoba kunye nokufikelela kulwazi oluyimfihlo. Ngaphezu koko, ukuba loo intanethi-sniffer wenza umsebenzi wayo ngqo, i-IP-idilesi umhlaseli zatshintsha. Kule nkalo, le applet thile ezifanayo abancedisi beproxy engaziwa ukuba sifihle IP umsebenzisi lokwenene. Ngenxa yezizathu ezicacileyo, data kwi ezi zibonelelo intanethi azikho nje ukungenelela yekhompyutha somnye esebenzisa ezi, iinkqubo ezifana, wawamisa ngokusemthethweni akukho mthethweni kunye wohlwaywe.
