Isithwebuli nokhuseleko computer Port

Into yokuba kukho inkqubo zibuko kugqibeke, uyazi yonke umsebenzisi computer. Yintoni umdla kukuba, ngokuyinxenye wachaza kulwazi ukhuphiswano ezinzima phakathi abaziingcibi izisombululo software zokuzikhusela ngezifo. Ngokomzekelo, iinguqulelo zangaphambili software wesi evela Kaspersky Labs iseshoni kunye uthungelwano lwehlabathi waphuma waya ngayo imiyalezo malunga ukuhlolisiswa uthotho lwakho ikhompyutha (ngokuxhomekeke kubungakanani yomsebenzi ngezibonelelo network). Kwi pop up-window, kwavakala ukuba umzamo ukuba scan kunye neyunithi yingozi evalekileyo. Iyaqondakala into yokuba abantu, ukubona izilumkiso ezininzi ngokuphathelele "neutralization" yimpumelelo, ukugqiba ukusebenza eliphezulu iinkqubo zokuzikhusela. Ngethamsanqa, ngendlela ukutsala ingqalelo ngokwakhe imisebenzi nokhuseleko, kwaye phantse lixesha ezininzi siyasebenza ngasemva.

Ngaphambi kokuba ujonge ukuba vuavanyisi port, ukuchonga kunye namanye amagama. Port - Eli candelo ikhowudi ye-network yedata (TCP okanye UDP), nto leyo ibonakalisa ekujoliswe kwaye abakhwetha isicelo. Masithi inkqubo lubangela inkqubo yokusebenza, isicelo sokufikelela kwinethiwekhi. Le nkqubo uphumeza zoququzelelo lokuqala lwenkqubo inani lezibuko, nto leyo iba yimali kuyo. Okulandelayo, oyithumela iipakethi data. Xa ukufumana impendulo uyezibuko, inkqubo uyisa data program oyifunayo. Yini eyenza? Yangaphandle port kugqibeke sijonga womnatha isinxulumanisi yekhompyutha ngokuthumela izicelo. Le aba "uziva phandle" interface, kukho uhlobo lovavanyo. Lo msebenzi ikuvumela ukuba ukujonga kumazibuko evulekileyo, ukuba ikhadi zabo. Kucacile ukuba, xa isicelo lwangaphandle ukuba izibuko closed akukho mpendulo ziya kuba, kodwa xa msebenzi ufumanise ukuba kanye kanye kwafuneka data alinde kule program. Emva esicacisa kumazibuko kunye izicelo, uhlaselo ngokwayo iqala. Kakade ke, ukuba iimeko zemvume: firewall ihleliwe ngokungachanekanga, amazibuko zivulekile, njalo njalo Kufuneka kuqatshelwe ukuba isixhobosovavanyo lwemifanekiso nje ukhuseleko ikhompyutha :. Ukuba ngaba uqinisekile emnyango Wozisibekekisa zisendlwini, makangehli knock njengoko befuna.

Loluphi uhlobo ukuhlasela ekuLunyukisiweyo ngazo zinakho ukuqhutywa ngendlela efanayo? Ekubeni isicelo kuyo yaziwa, unako ukwenza iphakheji ngendlela yokuba xa kusingathwa wasilela kwinkonzo womnatha (daemon ukuba ujongana izicelo network), kunye neziphumo aziwayo. Umzekelo, unako ukufikelela ulahliwe olupheleleyo zokulungisa iipakethi data engenayo (dos ukuhlasela) okanye usebenzisa semngciphekweni ezikhoyo ukuze bakwazi ukufikelela kwi ukwenziwa ekude imiyalelo kumatshini target. Amaninzi amaqonga ezizodwa iinkonzo ezikhoyo esidlangalaleni ukuze ikhubaze of a resource network (site) okwethutyana. oku kwenzeka njani kwaye ingaba isithwebuli zibuko? elula kakhulu. Ekubeni uyicacisile nkqubo, kumncediswe target ithunyelwa njengesihlambo enkulu (trash) ulwazi ngamampunge. Ngenxa yoko, umthamo omkhulu umncedisi kukho ukulibaziseka kakhulu ekusetyenzweni imibuzo luncedo ukuba kufuneka kuqala 'ukubamba' ukuhamba odla data. Noko ke, njengoko umgaqo, ukunqanda sithwalisa inkonzo wahlaselwa esanqunyanyiswe okwethutyana ngumlawuli. Le ndlela kuthiwa ngomkhukula.

Ukwandisa ukhuseleko computer yakho kuphunyezwa ngokufaka ukhuseleko ezizodwa lwesoftwe - firewalls. Baye kuzimela kwiindlela umgangatho zamazibuko ukukrwaqula, ukwenza ikhompyutha, enyanisweni, ezingabonakaliyo. Ukutyeshela yokufaka ayikho imfuneko. Hi ndlela leyi, i-firewall iqukwe kwiphakheji wesi Class Ukhuseleko Internet.

Khangela amazibuko evulekileyo ilula ngoncedo iziza ezizodwa detectors. Nje ukuya kuyo uze ucofe 'amazibuko Scan "(igama ziyahluka). Omnye kakuhle yaziwa - a 2ip Russian.
