Kev ruaj ntseg wireless pib nrog koj lub router
Txhawb koj lub tsev wireless network yog ib qho tseemceeb uas yuav tsum tiv thaiv cov neeg tiv thaiv hackers. Nyob rau hauv ntau lub tsev, tus router yog nruab nrab ntawm cov neeg siv hauv tsev thiab cov neeg uas yuav cuam tshuam lawv cov ntaub ntawv rau cov tsis muaj laj thawj. Txawm li cas los, tsuas yog ntsaws rau hauv lub router tsis txaus kom koj lub wireless network . Koj xav tau ib lub ntsiab tseem ceeb rau lub router thiab rau tag nrho cov khoom siv hauv koj lub tsev uas siv lub router. Lub wireless qhov tseem ceeb yog ib hom password uas siv rau ntawm Wi-nkaus wireless computer network kom lawv muaj kev ruaj ntseg.
WEP, WPA thiab WPA2 Yuam sij
WI-Fi Protected Access (WPA) yog qhov kev tiv thaiv kev ruaj ntseg uas siv rau Wi-nkaus tes hauj lwm. Tus qauv WPA qub tau pib rau xyoo 1999, hloov qhov txheej txheem hu ua Wired Equivalent Privacy (WEP) . Ib qho tshiab ntawm WPA hu ua WPA2 tau tshwm sim nyob rau xyoo 2004.
Tag nrho cov qauv no muaj xws li kev pab txhawb kev encryption, uas yog kev muaj peev xwm los daws cov ntaub ntawv xa mus rau ib lub wireless txuas kom nws tsis yooj yim yuav to taub los ntawm outsiders. Wireless network encryption siv cov txheej txheem kev ua lej raws li computer-generated random numbers. WEP siv ib qho kev xauv npawb hu ua RC4, uas yog tus thawj WPA hloov nrog Txoj Cai Tiv Thaiv Ib Ncig Tawm (TKIP). Ob leeg RC4 thiab TKIP raws li siv los ntawm Wi-nkaus tau raug xaus raws li kev soj ntsuam xyuas kev ruaj ntseg pom tau lawv cov kev ua haujlwm uas tau yooj yim los ntawm cov neeg tua neeg. WPA2 tau tshaj tawm Encryption Standard (AES) ua ib qho kev hloov rau TKIP.
RC4, TKIP, thiab AES txhua tus siv cov yawm sij wireless uas sib txawv ntev. Cov kev siv wireless no yog cov zauv hexadecimal uas sib txawv hauv ntev-feem ntau ntawm 128 thiab 256 khoom ntev-nyob ntawm qhov kev siv txoj kev siv encryption. Txhua qhov hexadecimal ntu nruab nrab yog plaub khoom ntawm tus yuam sij. Piv txwv, lub 128-ntsis qhov tseem ceeb yuav muab sau ua ib pawg neeg ntawm 32 tus lej.
Passphrases vs. Daws
Ib lub tshuas yog ib lo lus zais txuas nrog qhov tseem ceeb hauv Wi-nkaus. Cov ntawv Passphrases tuaj yeem yog qhov tsawg kawg nkaus ntawm yim thiab mus txog ntau tshaj 63 cim hauv ntev. Txhua tus neeg tuaj yeem yog ib daim ntawv loj, tsab ntawv txo qis, naj npawb, lossis cim. Cov cuab yeej ntawm Wi-nkaus tau txais kev hloov cov passphrases ntawm kev sib txawv ua ib qho tseem ceeb hexadecimal ntawm qhov yuav tsum tau ntev.
Siv Wireless Daws
Siv ib lub ntsiab tseem ceeb ntawm lub network hauv tsev, tus thawj tswj hwm yuav tsum xub ua kom muaj txoj kev ruaj ntseg ntawm txoj kev sib txuas hauv broadband . Cov neeg khiav dej num hauv tsev tau xaiv ntau txoj hauv kev xaiv xws li
- WEP
- WPA
- WPA2-TKIP
- WPA2-AES
Ntawm no, WPA2-AES yuav tsum tau siv thaum twg ua tau. Tag nrho cov khoom siv txuas mus rau lub router yuav tsum tau teem caij siv tib qho kev xaiv raws li lub router, tab sis tsuas yog qub Wi-nkaus cov cuab yeej tsis muaj AES kev txhawb nqa. Xaiv ib qho kev xaiv tseem hais kom tus neeg siv yuav tsum nkag mus rau ib qho kev sau ntawv yoojyim lossis tus yuam sij. Qee qhov kev tso cai nkag rau ntau lub pob uas tsis yog ib qho los muab cov thawj xibfwb tswj xyuas ntau tshaj kev ntxiv thiab tshem tawm cov cuab yeej ntawm lawv tes hauj lwm.
Txhua tus wireless ntaus ntawv txuas mus rau ib lub tsev network yuav tsum raug teem nrog tib lub phoojywg los yog tus tseem ceeb ntawm lub router. Lub ntsiab tseem ceeb tsis pub koom nrog cov neeg tsis paub.
