Sniffer mapasiwedi, maukonde. Sniffer - ndichiyani?

Ambiri owerenga makompyuta tamva za chinthu chotero monga "sniffer". Kodi ndi Komabe, kwathunthu kulingalira osati onse. Komanso, lero n'zotheka kuonetsetsa bwalo chochepa kwambiri cha anthu amene amadziwa kumene ntchito ngati pulogalamu ndi "chitsulo" zida. Tiyeni yesetsani kuthetsa zimene zomwe ziri.

Sniffer: ndichiyani?

Tiyeni tiyambe ndi tanthauzo la mawu. Kuti timvetse akamanena za nkhaniyi, zikhale zosavuta kuti ayambe kumasulira mawu akuti "sniffer". Ndi chiyani icho? The pomasulira Chingelezi mfundo sniffer ndi "Sniffer".

Mwachidule, ndi pulogalamu kapena zida angathe zochokera kusanthula magalimoto mu mawonekedwe a mapaketi opatsirana kapena kulandira deta pa maukonde kupeza mfundo zimene muyenela, kaya ndi kunja maukonde IP-maadiresi mapasiwedi encrypted kapena deta chinsinsi. Okha sniffers angagwiritsidwe ntchito kuvulaza ndi phindu.

The mitundu ikuluikulu ya sniffers

Monga mitundu ikuluikulu ya sniffers, izo si vuto mapulogalamu kuti waikidwa pa osachiritsika computer, kapena mu mawonekedwe a applet Intaneti.

Kawiri kawiri mutha kupeza sniffers mu mawonekedwe a "chitsulo" wa zida kapena zigawo kuti kuphatikiza ndi mapulogalamu, ndi ululu. Choncho, waukulu gulu sniffers monga mitundu zotsatirazi:

• mapulogalamu;
• hardware;
• fimuweya;
• Intaneti zigawo zikuluzikulu.

Pamene gulu chachikulu tingaone ndi kusanthula zina ndi malangizo kulekana. Mwachitsanzo, mitundu ambiri monga mapasiwedi sniffer, amene ntchito yaikulu ndi kuchotsa kwa deta mapaketi lotseguka kapena encrypted zizindikiro kulumikiza mfundo iliyonse. Pali sniffers yokhudza yekha mawerengedwe a yeniyeni osachiritsika IP-maadiresi kuti kulumikiza wosuta kompyuta ndi kusungidwa mu mfundo zake.

Kodi ntchito?

Technology kukakumana maukonde magalimoto ntchito yokhayo Intaneti zochokera ndondomeko TCP / IP ndi zomwe zagwiridwa kugwirizana kudzera makadi Efaneti maukonde. Intaneti opanda zingwe akhoza bwinobwino poyamba mulimonse chifukwa m'dongosolo amenewa pali kugwirizana yikidwa mawaya (kuti rauta, ndi Wopereka ndi laputopu kapena kompyuta PC).

Data kufala mu maukonde si yofunika wagawo, ndipo kudzera magawano ake mu kaphukusi ndi zigawo muyezo, imene kulandira mbali kulandira amaphatikizidwa mu amodzi umodzi. Program-sniffer akhoza younikira ndi zotheka kufala njira zonse lililonse gawo, ndipo pa nthawi ya kutengerapo (kutumiza) mapaketi mosadziteteza ndi zipangizo olumikizidwa kwa maukonde (routers, Aang'onoang'ono, masiwichi, kompyuta kapena mafoni zipangizo) opangidwa Tingafinye deta zogwirizana, amene anyamula ndi mapasiwedi chomwecho. Choncho, kuswa achinsinsi amakhala njira kwambiri makamaka ngati si encrypted.

Koma ngakhale pamene ntchito njira zamakono zapamwamba achinsinsi kubisa, akhoza opatsirana pamodzi ndi kiyi chogwirizana. Ngati ndi lotseguka kiyi kuti achinsinsi yosavuta. Ngati chofunika kwambiri encrypted, ndi tizilomboto mosavuta ntchito iliyonse pulogalamu-decoder, zomwe pamapeto pake komanso kuyambitsa akulimbana deta.

Kodi ntchito sniffer maukonde?

Field ntchito sniffers ndi chosiyana kwambiri. Ine sindikuganiza kuti aliyense sniffer yabwino ku Russian ndi njira yokha ndi hackers kuyesera kupanga kusokonezedwa wosaloleka mu magalimoto maukonde kuti apeze zina zofunika.

Ndi sniffers ofanana bwino zitha kugwiritsidwa ntchito ndi ogwira kuti zochokera kusanthula awo magalimoto deta opangidwa owerenga ake, utithandize chitetezo makompyuta. Ngakhale zida ngati ndi ntchito anatchula antisnifferami, kwenikweni ndi sniffers kwambiri wamba akufuna ntchito zosiyana.

Kumene, okonda zimenezi palibe amene amatithandiza WOPEREKA, ndi zomveka kwambiri mu izi. wosuta Private ndi chodziwikiratu kuti athe payekhapayekha kutenga countermeasures iliyonse. Ndipo nthawi WOPEREKA kusanthula magalimoto n'kofunika kwambiri chifukwa chingalepheretse ankafuna kusokoneza ntchito Intaneti zakunja kwa kusanthula mwayi popereka kaphukusi mukhoza younikira mwayi wosaloleka kwa iwo osachepera pa maziko a peripherals chomwecho IP-maadiresi, kuyesera kukakumana zigawo opatsirana. Koma ichi ndi chitsanzo lophweka, chifukwa luso onse ndi zambiri zovuta.

Kuona pamaso pa sniffer

Potuluka pambali chinthu chotero monga "sniffer". Chimene icho chiri, ndi bwino pang'ono tsopano onani pa maziko akhoza chimatanthauza ndi "wiretap" sniffer nazo.

Ngati kompyuta dongosolo ndi kwabwino, ndi maukonde kapena intaneti ikutha bwino, chizindikiro cha phukusi kunja ndi kuchepetsa mlingo paketi poyerekeza kuti imanenera ISP lapansi. M'magulu Windows ofotokoza ndi muyezo zikutanthauza kudziwa liwiro la wosuta pafupifupi sililimbikitsa ngakhale pamene maukonde udindo menyu kuitana mwa kuwonekera pa chizindikirochi kuti kulumikiza. Apa musankhe chokha chiwerengero cha mapaketi anatumiza ndipo analandira.

Mofananamo, ntchito mu "woyang'anira ntchito" anasonyeza anakhumba mfundo zonse, kuchepetsa chomwecho liwiro akhoza zogwirizana ndi zofooka za gwero umene kulumikiza ikuchitika. Ndi bwino kugwiritsa ntchito zipangizo zapadera, analyzers, umenenso njira, ndipo ntchito pa mfundo za sniffer. Chinthu chokha chimene inu muyenera kulipira tcheru, ichi ndi chokhacho chakuti mtundu uwu wa ndondomeko pambuyo unsembe zingachititse zolakwika zimene zimachitika chifukwa mikangano ndi firewalls (a makhoma oteteza anamanga-Windows kapena wachitatu chipani mapulogalamu ndi hardware "chitsulo" mtundu). Choncho, pa nthawi ya Zosefera kusanthula ndi zofunika kuletsa.

Pomaliza

Apa, kwenikweni, ndi chirichonse chochita ndi chinthu chotero monga "sniffer". Ndichiyani mawu a kuwakhadzula zipangizo kapena chitetezo, mfundo yake bwino. Mpaka kuwonjezera mawu ochepa za applets Intaneti. Iwo basi ali makamaka ntchito ndi hackers kupeza IP-adiresi ya munthuyo komanso kupeza zachinsinsi. Komanso kuti online-sniffer amachita ntchito yake mwachindunji, ndi IP-adiresi ya tizilomboto zinasintha. Pa nkhani imeneyi, applets awa chinachake chofanana ndi maseva anonymous tidzakulowereni kuti kubisa weniweni wosuta IP. Zifukwa zoonekeratu, deta pamanambala awa Intaneti si monga kusokonezedwa ndi kompyuta wina mwa izi, mapulogalamu monga, ndipo mwalamulo anaima ndi zoletsedwa ndi chilango.
