Sniffer mavara echivande, nomumbure. Sniffer - chii?

vanozvishandisa Vakawanda makombiyuta vakanzwa chinhu chakadai se "sniffer". Chii, zvisinei, kuti zvakazara fungidzira kwete zvose. Uyezve, nhasi zvinoita govera mashoma chaizvo denderedzwa vanhu vanoziva kushandisa chirongwa uye "simbi" midziyo yakadai sei uye kupi. Ngatiedzei wofunga chii chii.

Sniffer: chii?

Ngatitange pamwe tsanangudzo rokuti. Yokunzwisisa zvinorehwa nemashoko yacho, zvinofanira kuva nyore kutanga kushandura shoko "sniffer". Chii? The shanduro chaiyoiyo of Chirungu pfungwa sniffer ndiye "Sniffer".

Zvichitaurwa zviri nyore, ndiko chirongwa kana zvokushandisa inokwanisa kwakavakirwa motokari kuongorora muchimiro omumasherufu zvitange kana akagamuchira mashoko pamusoro pomumbure kuti anotora mashoko aunoda, kana zviri zvokunze rezvebonde IP-kero, encrypted mavara echivande kana zvakavanzika mashoko. Pachavo sniffers zvinogona kushandiswa kukuvadza uye kubatsira.

The Mhando chikuru sniffers

Kana huru mhando sniffers, zvingava hazvo kuva Software iri yakaiswa pakombiyuta chinouraya, kana akaita muchimiro paIndaneti applet.

Kazhinji ungawana sniffers muchimiro "simbi" zvokushandisa kana zvinoriumba kuti zvinobatana uye software, uye mumuviri zviratidzo. Nokudaro, mukuru kupatsanura sniffers zvinosanganisira marudzi anotevera:

• Software;
• Hardware;
• firmware;
• paIndaneti zvinoriumba.

Kana chikuru kupatsanura inogona chinozivikanwa mberi kuongorora uye nekupatsanurwa gwara. Somuenzaniso, rakajairika kwemarudzi akadai sniffer mavara echivande, ane basa chikuru ndiko dzokubvisa kubva mashoko omumasherufu rakazaruka kana encrypted Codes kuwana chero ruzivo. Pane sniffers nechokuita chete kukarukureta zvimwe chinouraya IP-kero kuti kuwana inodzidzisa kombiyuta uye inochengetwa mashoko ayo.

Ungazviita sei?

Technology gamha Network motokari rinoshanda chete flow kwakavakirwa TCP / IP protocols uye rakatangwa chokuita Via Ethernet Network nemakadhi. Wireless network inogona vakaongorora, pakutanga zvakadaro nekuti zvakadaro ezvinhu pane that no wired kubatana (kune router, anopa imwe Laptop kana pakombiyuta PC).

Data Kupfuudzwa ari paIndaneti hakusi chinokosha Unit, uye vachishandisa ayo kupesana mukati omumasherufu uye mwero zvikamu, iyo, kana kugamuchira nokupiwa divi ikashandiswa kuva chete chimwe. Program-sniffer anokwanisa chamber zvose zvinobvira hutachiwana hova nomumwe chidimbu, uye panguva kutapurirana (vorega) kudzivirirwa omumasherufu kuti mano chokuita pomumbure (routers, hubs, haizoshandisi, makombiyuta kana pafoni mano) yakabereka mushoma akakodzera data, izvo ingasanganisira zvakafanana mavara echivande. Saka, nokuputsa pasiwedhi kunova nevakawanda nzira, kunyanya kana haina encrypted.

Asi kunyange paaishandisa yemhando pasiwedhi encryption michina, rinogona kuparadzirwa pamwe runoenzanirana kiyi. Kana yakazaruka kiyi vawane Password nyore. Kana Chinokosha encrypted, imwe chibharo anogona kushandisa nyore chero Software-decoder, iyo pakupedzisira kutungamirira cracking walnut mashoko.

Where kushandisa sniffer Network?

Field yekushandiswa sniffers rakanyatsojeka zvakasiyana. Handifungi kuti chero yakakunakira sniffer muchiRussia ndiyo chete nzira hackers kuedza kuita kunze komutemo kuvhiringidzwa mubasa zvakarukwa motokari kuitira kuti mashoko anokosha.

Zvakaenzana kubudirira sniffers zvinogona kushandiswa rubatsiro kuti dzinobva kwavo kuongorora mashoko motokari yakabereka vanoshandisa ayo, dzekugonesa kuchengetedzwa makombiyuta. Kunyange zvazvo michina uye mafomu akadaro anotaurwa antisnifferami, chaizvoizvo ndiyo inonyanya vanhuwo sniffers vanoda kushanda negwara.

Chokwadi, vanoshandisa yezviito zvakadaro hakuna notifies Mugoveri, uye kuti zvikuru pfungwa iyi. Private mushandisi angangotadza kukwanisa vakazvimirira kutora chero countermeasures. Uye kazhinji Mupi motokari kuongorora kunokosha zvikuru nokuti kunogona kuedza kupindira mubasa nechitarisiko network, nokuti pokuongorora kumichina wokushandura omumasherufu, unogona chamber kunze komutemo kuwana kuti kanenge pahwaro chete peripherals IP-kero, vachiedza gamha zvitange zvikamu. Asi ichi ndicho muenzaniso nyore chaizvo, nokuti zvose mabikirwo zvakawanda kunzwisisa.

Pakusarudza kuvapo sniffer

Nepo kusiya parutivi chinhu zvakadai "sniffer". Chii, iri pachena zvishoma zvino kuona pane chikonzero zvinogona ndeakaita "wiretap" sniffer pachake.

Kana yekombiyuta iri OK, uye nomumbure kana Indaneti iri kumhanya zvakanaka, chiratidzo kunze kupindira wokutanga kuderedza packet zvazvingava, zvichienzaniswa kuti yakataurwa ISP. In Windows anotsanangura hurongwa pamureza kunoreva kuona kumhanya avhareji User kashoma kunyange apo nemambure mamiriro Muterere kumutumidza nekudzvanya pamusoro icon kubatanidza. Pano iwe zvakanyatsonanga chete uwandu akatuma uye akagamuchira omumasherufu.

Saizvozvowo, mabasa mu "basa maneja" vanoratidza achida mashoko zvakazara, kuti chete nokukurumidza rutapudzo zvinogona chokuita zvokukwegura zviri zvekuvaka kuti kuwana rinoitwa. Zvakanakisisa kushandisa maturusi analyzers, izvo, panzira, uye basa panheyo sniffer. The chete chinhu unofanira kubhadhara nezvechii, ichi ndicho chete ndechokuti urongwa pashure chokugadza kungaita zvikanganiso kuti kuitika nokuda zvinopesana firewalls (a firewall yakavakwa muna Windows rechitatu-party Software uye Hardware "simbi" mhando kana). Naizvozvo, panguva iyo nenyaya filters, zviri chinodiwa chokukuvadza.

mhedziso

Pano, chaizvoizvo, uye kuti vaite zvose izvozvo se "sniffer". Ko panyaya kugura zvishandiso kana dziviriro, pfungwa, tinofanira kuva pachena. Zvazvinosarira kuwedzera mashoko mashomanana pamusoro paIndaneti applets. Vanongouya vari kunyanya kushandiswa hackers kuwana IP-Kero wacho kuwana zvakavanzika ruzivo. Uyezve, kuti vakadaro paIndaneti-sniffer anoita ayo yakananga basa, kuti IP-kero zvebhinya uyewo achinja. Panyaya iyi, applets aya fananei ane kusazivikanwa Marshal servers kuti kuviga chaiye User IP. Nezvikonzero pachena, mashoko pamusoro izvi Indaneti mari havasi sezvo dzevamhan'ari nomumwe kombiyuta achishandisa izvi, wakafanana, uye pamutemo akamira zvirongwa zviri pamutemo uye kurangwa.
