Sniffer sniffer Network. Yintoni a sniffer: inkcazo

Abantu abaninzi abasebenzisa iiwebhsayithi computer, ngokubanzi, esingaziwayo into enjalo njenge "sniffer". Yintoni sniffer, kwaye izame ukumisela ngendlela elula usaqala. Kodwa kuqala, kusafuneka ukuba sijonge ikamva kwikota.

Sniffer: yintoni sniffer ngokwemigaqo kulwimi IsiNgesi kunye nezixhobo zekhompyutha?

Enyanisweni, ukuba ukujonga uhlobo software okanye hardware ne-software kulula ukuyenza, ukuba igama nje ukuguqulela.

Eli gama livela zijoje igama IsiNgesi (zijoje). Kungoko kubalulekile elithi "sniffer" elithetha isiRashiya. Yintoni a sniffer ukuqonda kwethu? "Sniffer" ezinokuthi ukulandelela ukusetyenziswa kwezithuthi womnatha, yaye, kalula, ndiyintlola ezinokuthi ukuphazamisa umsebenzi kothungelwano zasekuhlaleni okanye ojolise Internet ngokuthi ukuthatha iinkcukacha kufuneka ngokwesiseko ukufikelela kwi-transfer data kwiiprothokholi zeTCP / IP.

Analyzer Traffic: kusebenza njani?

Yithi kanye: sniffer, nokuba isoftware okanye software shareware candelo bakwazi ukuhlalutya kunye alukhawulele yezithuthi (ukukhupha nowamkela) ngokukodwa nge ikhadi network (Ethernet). kwenzeka ntoni?

Umsebenzisi womnatha akusoloko ukhuselwe ngodonga (kwakhona - software okanye "intsimbi"), kwaye ke ngoko esweni ezosulela okanye idatha eyafunyanwa kuba indaba kuphela yokuzenza.

Ngaphakathi network ulwazi ngapha komsindo. Phakathi ingxenye eyodwa kulindeleke uthumela iipakethi data ukuba ngokupheleleyo zonke izixhobo eqhagamshelwe kwinethiwekhi. ulwazi Segmental kuthunyelwa imizila (yasekhaya), kwaye ke ngoko ixesha sokuyivula (itshintshela) kunye concentrator (hub). Ithumela ulwazi eveliswe ngokwahlula zepakethe, ukuze umsebenzisi isiphelo sithi elidityaniswe kuyo zonke iindawo yempahla kunye ngokugqibeleleyo evela iindlela ezahlukeneyo. Ngoko ke, i "ukuphulaphula" zonke iindlela ezinokubakho ukususela omnye umsebenzisi ukuya kwenye, okanye intsebenziswano lwemvelaphi Internet kunye umsebenzisi ukunika nje kuphela ukufikelela data ingafihlwanga, kodwa kwabanye isitshixo efihlakeleyo, leyo nayo abanokuthunyelwa loonkqubo yentsebenziswano. Kwaye ngoko ke umsebenzisi womnatha akakhuselekanga ngokupheleleyo, ekubeni kukho ungenelelo ngumntu wesithathu.

neenjongo ezintle kunye neenjongo ngolunya?

Sniffers inokusetyenziswa ukwenzakalisa nokuzuza. Singasathethi nefuthe elibi, kubalulekile ukukhumbula ukuba iinkqubo hardware kunye software ezo asetyenziswa rhoqo ngabalawuli inkqubo abazama ukugcina umkhondo umsebenzi umsebenzisi hayi kuphela womnatha, kodwa ukuziphatha kwabo kwi-Internet ngokwemiqathango kwezibonelelo batyelela iyasebenza zokulanda kwiikhompyutha okanye ukuthumela kubo .

Inkqubo sokuqhuba analyzer womnatha, ilula. Sniffer ibona umatshini yendlela eziphumayo nezingenayo. Kule meko ke asithethi malunga IP yangaphakathi okanye yangaphandle thina. Isibaluli ibalulekileyo ekuthiwa-Mac-idilesi, unique ukuba isixhobo ngasinye eqhagamshelwe web ehlabathini. Loo nto yenzeka ukuchonga kumatshini ngamnye kwi-network.

iintlobo sniffers

Kodwa kwakhona ziindidi lungahlulwa-hlulwa zibe ezininzi:

• hardware;
• software;
• hardware kunye software;
• applets intanethi.

definition yokuziphatha sniffer phambi online

Fumana WiFi sniffer inye ibe phezu umthwalo womnatha. Xa ubona ukuba ugqithiso lwedata okanye uqhagamshelwano ayikho kwelo zinga, leyo kuthiwa yi ISP yakho (okanye ovumela umzila), kufuneka sinikele ingqalelo kuyo kwangoko.

Kwelinye icala, umboneleli kwakhona uyakwazi usebenzise udweliso lwenkqubo sniffer esweni izithuthi ngaphandle ulwazi lomsebenzisi. Kodwa umthetho, umsebenzisi musa nakubona. Kodwa kumbutho elinika iinkonzo ukudibanisa kwi Internet, ngaloo ndlela ukuqinisekisa ukhuseleko oluphezulu kumsebenzisi ngokwemiqathango iimbalelwano onogumbe, zahlukile abathengi self-esalo ' networks peer, Trojans, kubathengisi, njl Kodwa mali ezinjalo software ngakumbi kunye nefuthe okhethekileyo kwi-network, okanye kwi iitheminali umsebenzisi abanazo.

imithombo online

Kodwa analyzer traffic ezinobungozi inokuba on-line hlobo. Ekusetyenzisweni sniffers wakha inkqubo kusiko kwakudala. Technology ngenketho yayo elula kukuqinisekisa ukuba umhlaseli iinkuni original ibe resource ethile, uze emva koko ilayishiwe umfanekiso site. Emva kokuqinisekisa ikhonkco download enikwe kwi online-sniffer, nto leyo iya kuthunyelwa ibe lixhoba, umzekelo, ngohlobo lwe email okanye efanayo SMS-umyalezo kunye itekisi efana "Wena samkelayo umbulisayo into. Ukuvula umfanekiso (iposikhadi), cofa kwi link. "

abasebenzisi kom- nqakraza kwi ngokokugqama wathi, apho ukukhangelwa iyasebenza yaye nokudluliselwa IP Idilesi-lwangaphandle ukuya umhlaseli. Ngesicelo esisiso, akakwazi ukubona kuphela yonke idatha egcinwe kwi computer, kodwa kulula ukutshintsha izicwangciso inkqubo esuka ngaphandle, njengoko umsebenzisi awusayi nokuba unokuthekelela, ukuthatha utshintsho olunjalo ifuthe le ntsholongwane. Kodwa loo nto kuphela xa kutshekishwa vuavanyisi kuya zero izisongelo.

Indlela yokukhusela nxamnye iimbalelwano data?

Nokuba WiFi sniffer, okanye nayiphi na enye analyzer, inkqubo yokhuseleko ngokuchasene ukuskena engagunyaziswanga traffic lisekhona. enye kuphela: kufuneka ifakwe kuphela siqinisekile kwi "i-".

software enjalo ibizwa ngokuba "antisnifferami". Kodwa ke xa ucinga ngayo loo sniffers efanayo ukuhlalutya izithuthi, kodwa iibhloko ezinye iinkqubo ezizama ukufumana imvume yokungena.

Ngenxa yoko ngumbuzo othi: ubalulekile kwaye ufake le software? Mhlawumbi ngenye kwakhe imigewu ziphumeze umonakalo ngakumbi, okanye iya lock ngokwayo ukuba umsebenzi?

Kwimeko elula kunye neenkqubo-based Windows njengokhuselo kungcono ukuba usebenzise eyakhelwe-ngaphakathi Firewall (firewall). Maxa wambi kusenokubakho ukungavisisani Antivirus ifakiwe, kodwa usebenza rhoqo kuphela iiphakheji simahla. Professional wathenga uguqulelo ngenyanga okanye zisebenze ezi iziphene wobubi.

endaweni yokuba UYobi

Kuko konke oko kunxulumene ingcamango "sniffer". Yintoni na le sniffer, ndiyacinga, ngenxa abaninzi baqaphela. Ekugqibeleni lo mbuzo yenye: indlela kakuhle izinto ziya kusebenzisa umsebenzisi avareji? Nokuba eneneni phakathi Abasebenzisi abaselula maxa wambi ingabonwa notyekelo ukuya kalweni computer. Babecinga ukuba enye uthile lomnqweno yimfumba kaThixo "ikhompyutha" - yinto efana kukhuphiswano umdla okanye self-isiqiniselo. Ngelishwa, akukho namnye kubo abazange bade bacinge malunga neziphumo, yaye eneneni ukumisela umhlaseli usebenzisa sniffer online efanayo, ilula kakhulu ngenkangeleko alo IP, umzekelo, kwisiza Whois. Ngenxa indawo, enyanisweni, umboneleli indawo zizakuboniswa, Noko ke, eli lizwe kunye sixeko ngqo. Ke ngoko, nokuba incinane, nokuba kubiza i ISP ukuvala i-terminal, nto leyo eye ukufikelela ongagunyaziswanga okanye umcimbi ukuba iinkundla. Zoba izigqibo zakho.

Ukuba olufakwe inkcazelo inkqubo terminal deployment, ukusuka apho kukho ziinzame zokufikelela, oku kunjalo yaye kulula. Kodwa ngoku imiphumo inokuba yintlekele, ngenxa yokuba ingengabo bonke, abasebenzisi sebenzisa Heh anonymizer okanye proxy iiseva idesktop, kwaye musa nokuba thsuphe njani ukufihla IP yakho kwi-Internet.
