Fumana ukuba i-firewall yakho ye-PC / network yenza umsebenzi wayo?
Uvumelekile ukuguqula i-PC okanye i-Wireless Router ye-firewall kwindawo ethile, kodwa uyazi njani ukuba wenza umsebenzi walo?
Injongo ephambili yomnatha womnatha womlilo ukugcina nayiphi na into ekhuselekileyo ekukhuselekeni (kunye nengozi endithethayo ngabagculi kunye ne-malware).
Ukuba isebenze ngokuchanekileyo, i- firewall yenethiwekhi ingabangela ukuba iPC yakho ibonakali kubantu ababi. Ukuba abayiboni ikhompyutha yakho, ke abakwazi ukukujolisa ekuhlaseleni kusekelwe kwinethiwekhi.
I-Hackers isebenzisa amathuluzi okutshintshwa kwe- port ukuskena iikhomputha kunye namachweba avulekileyo angase adibanise amandla, awanikeze nge-backdoors kwikhompyutha yakho. Ngokomzekelo, usenokuba ufake ifayile kwikhompyutha yakho evula ichweba le-FTP. Inkonzo ye-FTP eqhubayo kuloo port ingaba nobuthathaka obufunyenwe. Ukuba umqwengqayo uyakubona ukuba unesivule evulekileyo kwaye unobungozi obunobungozi obusebenzayo, ngoko banokukuxhaphaza ubungozi kwaye bafumane ukufikelela kwikhompyutha yakho.
Omnye wabaqeshi abakhulu bokukhuseleka kwenethiwekhi ukuvumela kuphela izibuko kunye neenkonzo eziyimfuneko. Iiphulo ezimbalwa ezivulekileyo kunye neenkonzo ezisebenzayo kwinethiwekhi yakho kunye / okanye kwi-PC, iindlela ezimbalwa zokugculela kufuneka zizame kwaye zihlasele inkqubo yakho. I-firewall yakho kufuneka ikhusele ukufikelela okungenayo kwi-intanethi ngaphandle kokuba unezicelo ezithile ezizifunayo, njengesixhobo sokulawula esikude.
Unokuba ne-firewall eyingxenye yesistimu yokusebenza yekhompyutha . Unokuthi ube ne-firewall eyinxalenye yomzila wakho ongenazintambo .
Ngokuqhelekileyo yindlela ekhuselekileyo yokukhusela ukuvumela ukuba "i-stealth" imo kwi-firewall kwi-router yakho. Oku kunceda ukwenza inethwekhi yakho kunye nekhompyutheni ebonakalayo kubacuki. Hlola iwebhusayithi yakho yomenzi we-router ukuze uthole iinkcukacha malunga nendlela yokwenza inkqubela yefowuni.
Uyazi Njani Ukuba i-firewall yakho iyakhusela?
Ufanele uvavanye rhoqo i-firewall yakho. Indlela engcono yokuvavanya i-firewall yakho ivela ngaphandle kwintanethi yakho (ie intanethi). Kukho izixhobo ezininzi zamahhala ngaphandle apho kukukunceda ukufezekisa oku. Enye yeyona ndlela elula kwaye iluncedo kakhulu ifumaneka yiShieldsUP kwiwebsite ye-Gibson Research. I-ShieldsUP iya kukuvumela ukuba usebenze iiphakheji ezahlukeneyo kunye neenkonzo zokukhangela idilesi yakho ye- Intanethi leyo eya kubeka kuyo xa uvakashela isayithi. Kukho iintlobo ezine zezicatshulwa ezifumaneka kwisiza seShieldsUP:
Uvavanyo lokwabelana ngeFayile
Uvavanyo lokwabelana ngefayile luhlola iifama eziqhelekileyo ezichaphazelekayo kunye neenkonzo zokungenisa iifayile ezinobungozi. Ukuba ezi zibuko kunye neenkonzo ziqhuba oko kuthetha ukuba unakho umncedisi wefayili ofihliweyo osebenza kwikhompyutheni yakho, mhlawumbi uvumela abacuki ukuba bafikelele kwinkqubo yakho yefayili
Uvavanyo lweePorts eziqhelekileyo
Uvavanyo oluqhelekileyo lwamachweba luhlola iimangxube ezisetyenziselwa (ezinokuthi zisengozini) iinkonzo ezibandakanya i-FTP, iTelnet, i- NetBIOS kunye nabanye abaninzi. Uvavanyo luya kukuxelela ukuba umbane wakho okanye iimodi yekhompyutheni esebenzayo iyasebenza njengoko ipapashwe.
Zonke iiPorts kunye neeNkonzo zoVavanyo
Oku kuhlola iimvavanyo nganye kwi-port enye ukusuka ku-0 ukuya ku-1056 ukujonga ukuba zivulekile (kuboniswe obomvu), zivaliwe (kuboniswe eluhlaza okwesibhakabhaka), okanye kwimodi ye-stealth (iboniswe eluhlaza). Ukuba ubona naziphi na izibuko ebomvu kufuneka uphonononge ngakumbi ukuba ubone oko kusebenza kwezo zibuko. Khangela ukusethwa kwe-firewall yakho ukuze ubone ukuba ngaba ezi zibuko zenziwe ngeenjongo ezithile.
Ukuba awuboni nantoni kwi-firewall yakho ubeka uluhlu malunga nala machweba, kunokubonisa ukuba unayo i- malware esebenza kwikhompyuter yakho kwaye kungenzeka ukuba iPC yakho ibe yinxalenye yebhokisi . Ukuba kukho into ebonakala iyinhlanzi, kufuneka usebenzise umatshini wokulwa ne-malware ukujonga ikhompyutha yakho kwiinkonzo ze-malware ezifihliweyo
Uvavanyo logaxekile lomthunywa
Uvavanyo lwe-Spam Spam luzama ukuthumela umyalezo wokuvavanya we- Microsoft Windows Messenger kwikhompyutheni yakho ukubona ukuba i-firewall yakho ivimbela le nkonzo ingaqhutyelwa kwaye isetyenziswe ngabagaxekile ukuthumela imiyalezo kuwe. Olu vavanyo lujoliswe kubasebenzisi baseMicrosoft kuphela. Abasebenzisi beMac / Linux banokunqumla lo vavanyo.
Uvavanyo lokuValulwa kweSiphequluli
Ngelixa uvavanyo lwe-firewall, olu vavanyo lubonisa ukuba yeyiphi inkcazelo engabonakaliyo kwi-browser yakho malunga nawe kunye nenkqubo yakho.
Iziphumo ezingcono kakhulu onokuzithemba kuzo kule mvavanyo ziyakuxelelwa ukuba ikhompyutheni yakho in "I-Stealth True" kwaye i-scan ibonisa ukuba awunazo izibuko ezivulekile kwindlela yakho ebonakalayo / efumaneka kwi-Intanethi. Emva kokuba ufezekisile le nto, ungalala lula ngokungazi ukuba ikhomputer yakho ayinayo ibonakaliso enkulu enokuthi "Hayi! Nceda undihlasele."
