Sniffer: lokho sniffer ngokuya ngolimi lwesiNgisi kanye nemishini computer?

Empeleni, ukuze kutholwe ubunjalo software noma hardware ne-software Kulula ukwenza, uma nje ukuhumusha igama elithi.

Leli gama livela lesiNgisi elithi ehogela (ehogela). Yingakho ukubaluleka elithi "sniffer" abakhuluma isiRashiya. Uyini sniffer ukuqonda kwethu? "Sniffer" ukuthi ungakwazi ukulandelela ukusetshenziswa kwenethiwekhi, futhi, uma sikubeka kalula, ngiyinhloli ukuthi kungaphazamisa umsebenzi amanethiwekhi wendawo noma ngamakhasimende Inthanethi-by okukhipha ulwazi akudingayo ngesisekelo ukufinyelela ngokusebenzisa ukudluliswa kwedatha yezifiso TCP / IP.

Traffic Analyser: Ngabe isebenza kanjani?

Ithi ngesikhathi esisodwa: sniffer, kungaba isofthiwe noma isofthiwe shareware ingxenye uyakwazi ukuhlaziya kanye nciphisa traffic (ezithumela futhi zamukele) kuphela ngokusebenzisa ikhadi inethiwekhi (-Ethernet). Kwenzekani?

Esibonakalayo kwenethiwekhi ngaso sonke isikhathi ivikelwe isivikeli (aphinde - isofthiwe noma 'nensimbi'), ngakho-ke ukuqapha ngocansi noma idatha wathola iba kuphela kuyindaba yokukhathalelwa imiklamo.

Ngaphakathi inethiwekhi Imininingwane idluliselwa yonkana izingxenye. Phakathi eyodwa ingxenye sokulindelwe ukuthumela amaphakethe idatha ku ngokuphelele kuwo wonke amadivayisi ixhunywe kwinethiwekhi. Imininingwane Segmental kuthunyelwa imizila (imizila), bese sekuqalile (ukushintsha) kanye concentrator (HUB). Ukuthumela ukwaziswa ekhiqizwa sokuhlukanisa iphakethe, ukuze umsebenzisi ekupheleni Ufika exhunywe kwi zonke izingxenye iphakethe ndawonye ngokuphelele kusukela imizila ezahlukene. Ngakho, 'ukulalela' yonke imizila bevela umsebenzisi oyedwa kwesinye, noma ukuxhumana yomthombo Inthanethi nge umsebenzisi akakwazi kuphela zinikeza ukufinyelela kudatha ngokufihla, kodwa futhi ukuze ukhiye ezinye imfihlo, okuyinto nayo ingathunyelwa ku inqubo enjalo nokuxhumana. Bese esibonakalayo inethiwekhi engavikelekile ngokuphelele, ngoba kukhona ukungenela wesithathu.

Izisusa ezinhle futhi imigomo enonya?

Sniffers lungasetshenziswa ukulimaza kanye inzuzo. Ingasaphathwa nomthelela omubi, kuyafaneleka ukuthi onjalo hardware ne-software izinhlelo eminingi evame ukusetshenziswa abaqondisi uhlelo abazama ukugcina umkhondo umsebenzi womsebenzisi hhayi kuphela e inethiwekhi, kodwa futhi ukuziphatha kwabo ku-intanethi ngokuya izinsiza wavakashela isebenze okulandwayo ungene amakhompyutha noma ukuthumela kubo .

Inqubo asebenzisa analyzer inethiwekhi, ulula. Sniffer kuthola eziphumayo nezingenayo umshini traffic. Kulokhu asikhulumi mayelana IP yangaphakathi noma yangaphandle. Umbandela ebaluleke kakhulu okuthiwa i-MAC-ikheli, ehlukile kudivayisi ngayinye exhunywe kwi-web global. Lokho-ke kwenzeka ukuze abone emshinini ngamunye kunethiwekhi.

izinhlobo sniffers

Kodwa futhi izinhlobo zingahlukaniswa zibe eziningana:

• hardware;
• isofthiwe;
• hardware ne-software;
• applets inthanethi.

definition yokuziphatha sniffer khona online

Thola i-WiFi sniffer efanayo singaba umthwalo kwenethiwekhi. Uma ubona ukuthi ukudluliswa kwedatha noma uxhumano akuyona ngaleso ezingeni, okuyinto efunwe ISP yakho (noma evumela router), kufanele sinake ngokushesha.

Ngakolunye uhlangothi, umhlinzeki futhi ungagijima uhlelo sniffer ukuqapha traffic ngaphandle kolwazi yomsebenzisi. Kodwa njengoba umthetho, umsebenzisi nakuqaphela. Kodwa inhlangano inikeza amasevisi ukuxhuma kwi-Inthanethi, ngaleyo ndlela ukuqinisekisa ukuphepha esiphezulu umsebenzisi ngokuya uzamcolo ukucabhela, amakhasimende self-bakubheka 'ahlukahlukene kontanga zokuxhumana, Trojans, spyware, njll Kodwa lezo zimali kukhona isofthiwe okwengeziwe futhi ubungozi ekhethekile kunethiwekhi noma terminals umsebenzisi akudingeki.

izinsiza Online

Kodwa kuyingozi ngokukhethekile sezimoto analyzer kungaba on-line hlobo. On ukusetshenziswa sniffers eyakhelwe bakudala uhlelo nokugenca.

Ngemva kokuqinisekisa isixhumanisi thwebula esinikezwe inthanethi-sniffer, okuyinto ithunyelwa ibe isisulu, isibonelo, ngesimo imeyili noma okufanayo-SMS umyalezo ngombhalo njengokuthi "Wamukele bingelela nga okuthile. Ukuvula isithombe (lokuposa), uchofoze isixhumanisi. "

abasebenzisi Naive uchofoze isixhumanisi wathi, lapho ukuhlonza yasebenza futhi ukudluliswa zangaphandle IP-ikheli le-umhlaseli. Nge isicelo ezifanele, akanakuwubona kuphela yonke idatha egcinwe kukhompyutha, kodwa futhi kulula ukushintsha izilungiselelo zohlelo kusukela ngaphandle, njengoba umsebenzisi wendawo ngeke ngisho ukuqagela, ukuthatha lolo shintsho ngoba umthelela igciwane. Kodwa lokho kuphela uma uhlola isithwebuli uyonika zero izinsongo.

Indlela ukuvikela idatha ukucabhela?

Noma ngabe sniffer WiFi, noma yimuphi omunye analyzer, uhlelo isivikelo ukuskena okungagunyaziwe traffic sisekhona. ngaphansi kombandela owodwa: kufanele afakwe kuphela ngokugcwele "u-".

isofthiwe okunjalo uvame ukubizwa ngokuthi 'antisnifferami ". Kodwa uma ucabanga ngakho le sniffers efanayo ithrafikhi, kodwa amabhlogo nezinye izinhlelo zama ukuthola ukufinyelela okungagunyaziwe.

Ngakho-ke kuyinto kombuzo: kuwufanele futhi ukufaka le software? Mhlawumbe nokugenca yakhe kubaduni inflict umonakalo nakakhulu, noma-ke izokhiya ngokwayo ukuthi kufanele umsebenzi?

Endabeni elula nge izinhlelo Windows-based njengoba Ukuvikelwa kungcono ukusebenzisa esakhelwe firewall (firewall). Ngezinye izikhathi kungase kube liphambana Antivirus ifakiwe, kodwa ngokuvamile usebenza kuphela amaphakheji khulula.

Bese incane: noma ushayele ku-ISP ukuvimba esibulalayo, okuyinto usuqalise ukufinyelela okungagunyaziwe noma udaba ngoba izinkantolo. Zinqumele.

Uma olufakiwe Uhlelo definition esibulalayo ukuthunyelwa, kusukela lapho kukhona ngomzamo ukufinyelela, lokhu kwenzeka futhi kulula. Kodwa manje kungaba nemiphumela eyinhlekelele, ngoba akubona bonke, abasebenzisi ukusebenzisa virtual Heh anonymizer noma ummeleli amaseva, futhi abanayo ngisho nemizi umkhondo kanjani ukufihla IP yakho ku-intanethi. Futhi kuyafaneleka ukufunda ...
