Wi-Fi kev ruaj ntseg tseem ceeb heev, Thiab tsuas yog vim koj siv lub wireless nkag mus nrog encryption, tsis txhais tau tias koj muaj kev nyab xeeb. Hackers xav kom koj ntseeg tias koj muaj kev tiv thaiv kom koj thiaj li muaj kev cuam tshuam rau lawv qhov kev tawm tsam.
Nov yog plaub yam tseem ceeb uas koj yuav tsum paub txog kev ruaj ntseg Wi-nkaus.
WEP Encryption Tsis Muaj Kev Tiv Thaiv
WEP, uas sawv cev rau Wired Equivalent Privacy yog yooj yim tawg nyob rau hauv feeb thiab tsuas yog muab cov neeg siv nrog qhov tsis tseeb ntawm kev ruaj ntseg. Txawm tias tus neeg nyiag khoom nruab nrab tuaj yeem kov yeej WEP-raws li kev ruaj ntseg hauv ib feeb, ua rau nws tsis muaj txiaj ntsig zoo li kev tiv thaiv mechanism.
Ntau tus neeg teeb tsa lawv lub wireless routers ntau xyoo dhau los thiab tsis tau thab hloov lawv cov wireless encryption los ntawm WEP mus rau qhov tshiab thiab muaj zog WPA2 kev ruaj ntseg. Encrypting koj lub wireless network nrog WPA2 yog txheej txheem ncaj nraim. Mus ntsib koj lub chaw tsim khoom wireless router lub vev xaib rau cov lus qhia.
MAC lim tsis muaj txiaj ntsig thiab yooj yim kov yeej
Txawm hais tias nws yog lub computer, game system, tshuab luam ntawv, lossis lwm yam khoom siv, txhua daim IP-based hardware muaj qhov tshwj xeeb nyuaj-coded MAC chaw nyob hauv nws lub network interface. Ntau lub routers tso cai rau koj tso cai lossis tsis kam nkag mus rau lub network raws li lub cuab yeej MAC chaw nyob.
Lub wireless router tshawb xyuas MAC chaw nyob ntawm lub network ntaus ntawv thov kev nkag thiab muab piv rau koj cov npe tso cai lossis tsis kam lees MAC. Nws suab zoo li ib qho kev ruaj ntseg zoo heev, tab sis qhov teeb meem yog tias hackers tuaj yeem "spoof" lossis forge ib qho chaw nyob MAC cuav uas phim qhov pom zoo.
Txhua yam lawv yuav tsum tau ua yog siv lub pob ntawv kaw lus wireless los hnia (eavesdrop) ntawm kev khiav tsheb tsis muaj zog thiab pom MAC chaw nyob twg tau hla lub network. Lawv tuaj yeem teeb tsa lawv qhov chaw nyob MAC kom phim ib qho uas tau tso cai thiab koom nrog lub network.
Disabling Your Remote Administration Feature Works
Ntau lub wireless routers muaj qhov chaw tso cai rau koj tswj hwm lub router ntawm kev sib txuas wireless. Koj tuaj yeem nkag mus rau tag nrho cov routers kev ruaj ntseg teeb tsa thiab lwm yam yam tsis tas yuav tsum nyob hauv lub khoos phis tawj uas txuas rau lub router siv Ethernet cable.
Thaum qhov no yooj yim rau kev tswj hwm lub router nyob deb, nws kuj tseem muab lwm qhov nkag rau tus neeg nyiag nkag mus rau koj qhov chaw ruaj ntseg thiab hloov lawv mus rau qee yam me ntsis ntxiv rau hacker-phooj ywg.
Ntau tus neeg yeej tsis hloov tus password rau tus thawj tswj hwm ntawm lawv lub wireless router, uas ua rau txhua yam yooj yim dua rau tus neeg nyiag nkas. Peb pom zoo kom tig qhov "tso cai admin ntawm wireless" feature tawm yog li tsuas yog ib tus neeg uas muaj lub cev sib txuas rau lub network tuaj yeem sim tswj hwm lub wireless router teeb tsa.
Public hotspots feem ntau tsis ruaj ntseg
Hackers tuaj yeem siv cov cuab yeej xws li Firesheep thiab AirJack los ua "tus txiv neej hauv nruab nrab" kev tawm tsam. Lawv muab lawv tus kheej tso rau hauv kev sib tham wireless ntawm tus xa thiab tus txais.
Thaum lawv tau ua tiav lawv tus kheej rau hauv txoj kab kev sib txuas lus, lawv tuaj yeem sau koj tus lej password, nyeem koj tus email, saib koj IMs, thiab lwm yam. Lawv tuaj yeem siv cov cuab yeej xws li SSL Sawb kom tau txais lo lus zais rau cov vev xaib ruaj ntseg uas koj mus saib.
Peb pom zoo kom siv cov chaw muab kev pabcuam VPN kev lag luam los tiv thaiv tag nrho koj cov tsheb khiav thaum koj siv wi-fi tes hauj lwm. VPN ruaj ntseg muab ib txheej ntxiv ntawm kev ruaj ntseg uas nyuaj heev rau swb. Koj tuaj yeem txuas rau VPN ntawm lub xov tooj smartphone kom tsis txhob nyob hauv qhov muag nyuj. Tshwj tsis yog tias tus neeg nyiag nkag tau txiav txim siab tshwj xeeb, lawv yuav muaj feem yuav txav mus thiab sim ua lub hom phiaj yooj yim dua.
