Packet inofungidzira inogona kunge yakanzwika seyakagadzirwa nemugwagwa, asi iri kure nayo. Packet sniffers kana protocol analyzers ndiwo mashandisi anowanzoshandiswa nevanowanikwa mumagetsi kuti vaongorore zvinetso zvehutano. Packet sniffers inogonawo kushandiswa nevekugadzirisa zvishoma pane zvinangwa zvakanaka zvakadai sokutsvaga pane network user user uye kuunganidza pasi password.
Ngatitarisei kuti pakiti pikiti inopisa uye chii chainoita:
Packet sniffers inouya nenzira dzakasiyana-siyana. Mamwe mapepa ekufambisa anoshandiswa nevashandisi vemagetsi ndeye-single-purpose dedicated dedicated hardware solutions apo imwe pikisa sniffers mapurogiramu epurogiramu anoshandiswa pamakombiyuta akaenzana yevashandi-bhidhiyo, achishandisa hardware yehutano inowanikwa pamakombiyuta anogadzirisa kuita mapepa ekutora nekujekesa mabasa.
Ko Packet Sniffers Inoshanda Sei?
Packet sniffers inoshanda kuburikidza nekubvisa uye kugadzira mitambo yenzira iyo vanogona 'kuona' kuburikidza newired or wireless network interface iyo packet sniffing software inogona kuwana pane kombiyuta yayo.
Pachikwata chemawindo, chii chinogona kutorwa chinoenderana nesarudzo yehutano. Pepetti sniffer inogona kukwanisa kuona mutengesi pane imwe nhandare kana imwe nzvimbo imwe chete yayo, zvichienderana nekuti network network switches yakagadziriswa sei, yakaiswa, nezvimwewo. Pakombiyuta isina michina, packet sniffers inowanzotora rimwe chiteshi panguva imwe chete kunze iyo yekombiyuta yakawanda ine yakawanda isina wire interfaces inobvumira multichannel kubata.
Kana imwe nguva papepa yepaketeni yakatorwa, pakambodheta purogiramu software inofanira kuiongorora uye kuiisa mumhando yevanhu inogona kuverengwa kuitira kuti munhu anoshandisa purogiramu yekufema purogiramu anogona kuve nenzwisisiro. Munhu ari kuongorora deta anogona kutarisa mashoko e'kukurukurirana 'kunoitika pakati peviri kana kupfuura nodes pane network. Nyanzvi dzemagetsi dzinogona kushandisa ruzivo urwu kuti rurege kuti pane chinenge chakanganisa, zvakadai sekuona kuti chipi icho chakakundikana kupindura kubasa rekunamata.
Vanokanganisa vanogona kushandisa sniffers kuti vavedrop pane data isina kunyorwa mumapatete kuti vaone kuti ndeupi ruzivo rwakapatsanurana pakati pemapato maviri. Vanogonawo kutora ruzivo rwakadai sepa passwords uye zvinyorwa zvekutendesa (kana zvakatumirwa kune zvakajeka). Vanokanganisa vanogonawo kutora mapepa okuzorora gare gare mu replay, man-in-the-middle, uye kushandiswa kwepaketeni inokonzerwa nezvimwe zvirongwa zvingave zvisingakwanisi.
Ndezvipi Zvishandiso Zveshandisi Zvinowanzoshandiswa muPaketet Kuchenesa?
Kungofanana nevamwe vose, vose vanogadzira injini nevanotengesa vanoda zvinhu zvisingabhadharwi, ndicho chikonzero chakazaruka chivako uye freeware sniffer software yekushandura inowanzova zvishandiso zvekusarudza kwepakete yekunyora mabasa. Chimwe chezvinyanya kuzivikanwa zvakasununguka zvipo zvinonzi Wireshark (yaimbozivikanwa seEthereal).
Ndingadzivirira Sei My Network uye Dhiyabhorosi Yaro Kubva Pakutengesa Kushandisa Sniffers?
Kana iwe uri nyanzvi yekugadzira mitambo kana mutungamiri uye iwe unoda kuona kana munhu ari paunetaneti yako achishandisa chigadziro che sniffer, chengeta chigoni chinonzi Antisniff. Antisniff inogona kuona kana network inoshandiswa pane yako network yakagadzirirwa mu 'promiscuous mode' (usaseka iyo ndiyo zita chaiyo rayo), iyo ndiyo inodiwa mode ye packet capture tasks.
Imwe nzira yekudzivirira mitero yako yekutengesa kubva kunyoreswa ndeyokushandisa kuvhara seSecure Sockets Layer (SSL) kana Transport Layer Security (TLS) . Kuvharidzira hakubvumiri packet sniffers kubva pakuona ruzivo rwekubva kune imwe nzvimbo uye kune imwe nzvimbo, asi inonyora purogiramu yekubhadharwa kwepa data kuitira kuti iyo yose inononoka ione yakavharwa gibberish. Chero chero chiedza chekuchinja kana kuisa dhamusi mumapatete zvingangokundikana kubva pakushambadzira ne data yakavharidzirwa inogona kuita kuti zvikanganiso zvingaratidzike apo mashoko akavharidzirwa akadziviswa pane imwe mugumo.
Sniffers ndiyo midziyo yakaisvonaka yekuongorora pasi-in-the-weeds network matambudziko. Zvinosuruvarisa, zvinobatsirawo pakutsvaga zvinangwa zvakare. Zvakakosha kune vadzidzisi vekuchengeteka kuti vazive nemathuluzi aya kuitira kuti vaone kuti mutengesi angashandise sei pamusangano wavo.
