Thola ukuthi i-firewall yakho ye-PC / yenethiwekhi yenza umsebenzi wayo?
Kungenzeka ukuthi uphendule isici sakho se-PC noma i-Wireless Router's firewall ngesikhathi esithile, kodwa wazi kanjani ukuthi wenza umsebenzi wakhe ngempela?
Inhloso eyinhloko ye-firewall yomuntu siqu yokugcina inethiwekhi ukugcina noma yikuphi okukuyo ephephile engozini (nangomonakalo engikukhuluma ngabo abaduni kanye ne-malware).
Uma kusetshenziswe kahle, i- firewall yenethiwekhi ingenza ukuthi i-PC yakho ibonakale kubantu ababi. Uma behluleka ukubona ikhompyutha yakho, ngeke bakwazi ukukukhomba ekuhlaselweni okusekelwe enethiwekhi.
Abaqaphi bangasebenzisa amathuluzi wokuskena kwe-port ukuskena ama-computer ngamapayipi avulekile okungenzeka ahlose ukukhubazeka, abanikeze nge-backdoors kukhompyutha yakho. Isibonelo, kungenzeka ukuthi ufake ifoni kwikhompyutha yakho evula i-port FTP. Isevisi ye-FTP egijima kuleso port ingaba nengcupheni esanda kutholakala. Uma umqaphi angabona ukuthi unezibuko ezivulekile futhi unomsebenzi osengozini osebenzayo, khona-ke bangakwazi ukuxhaphaza ukutheleleka futhi bathole ukufinyelela kukhompyutha yakho.
Omunye wabaqashi abakhulu bokuphepha kwenethiwekhi ukuvumela kuphela amarekhodi namasevisi adingekayo ngokuphelele. Amapayipi ambalwa avulekile namasevisi asebenza kwinethiwekhi yakho kanye / noma i-PC, imizila embalwa abaduni kumele bazame ukuhlasela uhlelo lwakho. I-firewall yakho kufanele ivimbele ukufinyelela okungenayo kusuka ku-intanethi ngaphandle kokuthi unezinhlelo ezithile eziyidingayo, njengethuluzi lokuphatha elikude.
Cishe ube ne-firewall eyingxenye yesistimu yokusebenza yekhompyutha yakho . Ungase futhi ube ne-firewall engxenyeni yomzila wakho ongenazintambo .
Ngokuvamile kuyindlela yokuphepha engcono kakhulu yokuvumela imodi "ye-stealth" ku-firewall ku-router yakho. Lokhu kusiza ukwenza inethiwekhi yakho nekhompyutha engabonakali kubaduni. Hlola iwebhusayithi yakho yomkhiqizi we-router ukuze uthole imininingwane yokuthi ungayenza kanjani isici semodi ye-stealth.
Ngakho Uyazi kanjani ukuthi i-Firewall yakho iqinisile ikuvikela?
Kufanele uhlole ngezikhathi ezithile i-firewall yakho. Indlela engcono yokuhlola i-firewall yakho iphuma ngaphandle kwenethiwekhi yakho (ie Internet). Kunamathuluzi amaningi wamahhala ngaphandle lapho ukukusiza ukuthi ufeze lokhu. Enye yezinto ezilula futhi eziwusizo ezitholakalayo yiShieldsUP kusuka kuwebhusayithi ye-Gibson Research. I-ShieldsUP izokuvumela ukuba ugijime amathrekhi amaningana namasevisi ahlukahlukene ahlose ngokumelene nekheli lakho le-IP yenethiwekhi elizokwenza ukuthi unqume nini lapho uvakashela isayithi. Kunezinhlobo ezine zezilinganiso ezitholakala kusayithi le-ShieldsUP:
Ukuhlola Ikwabelana Ngefayela
Ukuhlolwa kwe-share sharing kuhlola amarekhodi ajwayelekile ahlobene namaphakheji nokwabelana ngamafayela afanelekayo. Uma lezi zichwephesha nezinsizakalo zigijima kusho ukuthi ungaba nesiphakeli sefayela efihliwe esebenza kukhompyutheni yakho, mhlawumbe evumela abaduni ukuba bafinyelele ohlelweni lwakho lwefayela
Ukuhlolwa kwamachweba avamile
Izivivinyo ezijwayelekile ezihlolwayo zihlola amachweba asetshenziselwa izinsizakalo ezithandwayo (futhi kungenzeka zisengozini) kuhlanganise ne-FTP, iTelnet, NetBIOS , nabanye abaningi. Ukuhlolwa kuzokutshela ukuthi imoto yakho noma imodi ye-stealth yekhompiyutha isebenza noma isetshenzisiwe noma cha.
Zonke Ukuhlolwa Kwezindawo Nezinkonzo
Lokhu kuhlola ukuhlola zonke izibuko ezivela ku-0 kuya ku-1056 ukubona ukuthi zivulekile (kuboniswe ngokubomvu), ivaliwe (kuboniswe eluhlaza okwesibhakabhaka), noma kumodi ye-stealth (kuboniswe eluhlaza). Uma ubona noma yiziphi izikebhe ezibomvu kufanele uphenye ngokuqhubekayo ukuze ubone ukuthi kusebenza yini kulawo machweba. Hlola isethaphu sakho se-firewall ukuze ubone ukuthi lezi zichweba zengezwe ngenjongo ethile.
Uma ungaboni noma yini ohlwini lwakho lwemithetho ye-firewall uhlu oluphathelene nalezi zichweba, lungabonisa ukuthi unayo i- malware esebenza kukhompyutheni yakho futhi kungenzeka ukuthi i-PC yakho ingaba yingxenye ye- botnet . Uma okuthile kubonakala kunenhlanzi, kufanele usebenzise isithwebuli se- anti-malware ukuhlola ikhompyutha yakho ngezinsizakalo ze-malware ezifihlekile
Ukuhlolwa kogaxekile kwabangani
Uhlolo logaxekile lwe-Messenger luzama ukuthumela umyalezo wokuhlola we- Microsoft Windows Messenger kwikhompyutha yakho ukubona ukuthi i-firewall yakho ivimbela le nsizakalo engasetshenziswa futhi isetshenziswe ngabagaxekile ukukuthumela imiyalezo. Lokhu kuhlolwa kuhloswe kubasebenzisi be-Microsoft Windows kuphela. Abasebenzisi be-Mac / Linux bangase badlule lesi sivivinyo.
Isivivinyo sokudalula kwesiphequluli
Nakuba kungenjalo ukuhlolwa kwe-firewall, lokhu kuhlolwa kubonisa ukuthi yiluphi ulwazi isiphequluli sakho esingase sichaze ngawe nesistimu yakho.
Imiphumela engcono kakhulu ongayethemba kuyo kulezi zivivinyo kufanele utshelwe ukuthi ikhompyutha yakho imodi ye "True Stealth" nokuthi ukuskena kwembula ukuthi awunawo amarekhodi avulekile ohlelweni lwakho olubonakalayo / olufinyeleleka kusuka ku-inthanethi. Uma usuzuzile lokhu, ungalala lula ukuthi ukwazi ukuthi ikhompyutha yakho ayibambeli uphawu olukhulu oluthi "Hamba! Ngicela ungishaye."
