Isixhobosovavanyo lwemifanekiso: ngokunyula kunye nokukhuselwa kulo

isixhobosovavanyo lwemifanekiso yenye imisebenzi kakhulu ethandwa eyenziwa ngabalawuli nkqubo. Akuthandeki ukuba kukho enjalo IT-specialist ongakaze kwimisebenzi yabo zange ukusebenzisa umyalelo ping, ekwimo omnye okanye omnye ifakiwe nayo nayiphi na inkqubo yokusebenza. Iyafuna ingqalelo lo mbandela ngokweenkcukacha.

indawo scan

Enyanisweni, a scan womnatha sisixhobo esinamandla kakhulu, esetyenziswa rhoqo ukuze kumiswe njenge womnatha, kunye nezixhobo womnatha. Xa zokusombulula nodes kwaye lwenziwa nokusebenza. Hi ndlela leyi, ukongeza ukusebenzisa iinjongo zoshishino, lwemifanekiso - kukwayinto entle sisixhobo othandwayo nayiphi umhlaseli. Zonke sesona sixhobo idume uvavanyo womnatha sadalwa imigewu abaqeqeshiweyo. Ngoncedo lwabo kunokwenzeka ukuba aqhube bahlolwa womnatha kwaye uqokelele zonke eziyimfuneko iinkcukacha malunga iikhompyutha ezinento kuyo. Ngoko ufumanise uhlobo yintoni network lwezakhiwo, isetyenziswa ntoni izixhobo, nto leyo amazibuko zivuleleke esuka kwikhompyutha. Oku zonke iinkcukacha yokuqala efunekayo ukuze ukuzivula. Ekubeni eziluncedo zisetyenziswa abahlaseli, emva koko uzisebenzise ukufumana phandle zonke iindawo womnatha sesichengeni ngexesha nokusetha.

Ngokubanzi, inkqubo lungohlulwa lube iintlobo ezimbini. Amanye asebenza ukuhlolisisa IP-iidilesi kumnatha womsebenzi wobulali, kunye nezinye amazibuko ziya kuskenwa. Loo lwahlulo kuthiwa ngendlela engaqondakaliyo, ekubeni inkoliso izixhobo idibanisa zombini imisebenzi.

Uvavanyo IP Idilesi-

Uthungelwano Windows idla oluninzi iimoto. Indlela sokuNgqinisisa IP-needilesi zazo uthumela ICMP-iipakethi kwaye elindele impendulo. Ukuba packet ifunyenwe, ikhompyutha okwangoku isanxulumane kwi thungelwano kule dilesi.

Xa kucingwa izakhono ICMP-protocol kufuneka kuqatshelwe ukuba womnatha Izakuvavanya usebenzisa ping kwaye efanayo eziluncedo nje isesisiqalo. Xa iipakethi exchange uyakwazi ukufumana iinkcukacha ezibaluleke ngakumbi isibakala yokuqhagamshelana esiludumbo kwinethiwekhi kwi dilesi ethile.

Indlela yokukhusela wena ukusuka isixhobosovavanyo lwemifanekiso IP-iidilesi?

Ngaba kunokwenzeka ukuba uzikhusele ngokwakho koku? Ewe, ufuna i lock kwi iimpendulo izicelo ICMP-protocol. Le yeyona ndlela isetyenziswa ngabalawuli abakukhathaleleyo ukhuseleko womnatha. Okubaluleke ngokulinganayo ukukwazi ukuthintela ngowona scan womnatha. Ngokuba lo unxibelelwano encinane nge ICMP-protocol. Nangona lula wayo, ukuqinisekiswa iingxaki womnatha, ngayo nayo le ngxaki kunye nokudala. Nokufikelela okungenasithintelo, imigewu bayakwazi ukwenza uhlaselo.

port ukuskena

Kwiimeko apho ICMP ipakethe Exchange ivaliwe, indlela isixhobosovavanyo lwemifanekiso Izibuko isebenziselwa. Ukuba umgangatho amazibuko scanning idilesi nganye kunokwenzeka, kunokwenzeka ukuba ukwazi yeyiphi iindawo oxhulumene kwi-network. Kwimeko yokuvulwa uyezibuko okanye kwimo yokulinda, ungabona ukuba kule dilesi kukho ikhompyutha into edityaniswe kwi network.

amazibuko lwemifanekiso kuba kudidi lwe TCP-ukumamela.

Indlela uzikhusele amazibuko ukuphulaphula?

Akubonakali, kunokwenzeka ukuba ukuthintela umntu uzame ukuze ajonge amazibuko kwi computer. Kodwa kusenokwenzeka ukuba nitrogen Enyanisweni zokumamela, emva koko ukuba kungenzeka ukuba kuncitshiswe imiphumo kunokwenzeka ezingemnandi. Ukwenza oku ngokufanelekileyo ukuze uqwalaselo kwaye ukhubaze iinkonzo firewall ezingasetyenziswayo. Yintoni ukusetwa kwinkqubo yokusebenza firewall? Xa ndivala, onke amazibuko ezingasetyenziswanga. Ukongeza, zombini software kunye firewalls iintsimbi Sithole ubukho umsebenzi inkxaso egqiba izama ukuhlola kumazibuko. Eli thuba kufuneka ityeshelwe.
