Kunzwisisa kutyisidzika uye nzira yekudzivirira mitero yako pamusoro pavo
Kunakidzwa Pasi
Iko kushandiswa kwemasiterevhiti asina maturo anouya nemutengo kunyange zvakadaro. Wired network access inogona kudzorwa nokuti data iri mune mukati mekateti iyo inobatanidza kombiyuta kuchinja. Neine wireless network, "cabling" pakati pemakombiyuta uye shandura inonzi "air", iyo ipi zvayo iri mukati mayo inokwanisa kuwana. Kana munhu angashandura ne-wireless access point kubva pamamita mazana matatu kubva ipapo, ipapo munyanzvi kuitira kuti pane mumwe munhu ari mukati memakiromita mazana matatu emusana usina kufanira.
Zvinotyisidzira kuWinless Network Network
- Rogue WLAN's - Chero basa renyu rakagamuchirwa mvumo yekutengesa wireless network kana kwete, midzi dzisina wireless dzinodhura, uye vashandisi vezvido vanogona kuvhara midziyo isina kupiwa mumutambo. Izvo zvinotyisa zvisingabviri mitambo zvingave zvisina kuchengeteka kana zvisina kukodzera kuchengetedzwa uye zvinokonzera njodzi kumusangano mukuru.
- Spoofing Communications Internal - Anokurwisa kubva kunze kwenhare inowanzoonekwa seichi. Kana munhu anopikisa achigona kushamwaridzana neWLAN yako, vanogona kuderedza hutano hunoonekwa hunobva kumadziro edzikati. Vashandi vakanyanya kunyanya kuvimba nekuita zvekutengesa mukati mehuta.
- Kubva kweNetongwa Resources - Kunyange kana muchengeti asingasviki makombiyuta ako kana kuisa purogiramu yako data, vangave vauya kuWLAN yako uye kuvhara network yako bandwidth kuti vashandise paWebhu. Vanogona kutora bhizimusi rakakwirira rakawanikwa pane dzakawanda mabhizinesi ekutengesa mimhanzi nemavhidhiyo mavhidhiyo, uchishandisa yako inokosha mitero yemichina uye inokonzera mitambo yevashandi kune vashandisi vako vakarurama.
Kuchengetedza Your Network kubva WLAN Yako
Kuvandudzwa kwakachengeteka chikonzero chakanakisisa chekuisa WLAN yako pachayo paVLAN. Iwe unogona kubvumira zvese zvese zvisina chipfeve kuti zvibatanidze kune WLAN, asi chengetedza zvese zvekunze kwenhare yako kubva kune dzimwe nyaya kana kushorwa kunogona kuitika pane wireless network.
Uchishandisa firewall, kana router ACL (access control control lists), unogona kurega kutaurirana pakati peWLAN nedzimwe nhare. Kana iwe ukanyatsobatanidza WLAN kune inyanzvi yekunze kuburikidza ne proxy web kana VPN, unogona kunyange kudzivirira kusvikirwa nemagadziri asina tsvina kuitira kuti vanokwanisa kungovhura paIndaneti, kana kuti vanongobvumirwa kusvika kune mamwe mafaira kana maitiro.
Secure WLAN Access
Wireless Encryption
Imwe yenzira dzekuita kuti vashandi vasingabvumirwi vasaita yevesdrop pane yako ye wireless network ndeyekuvhara deta yako isina deta. Nzira yepakutanga yakavhara, WEP (wired yakafanana yega), yakawanikwa yakakanganisika. WEP inotenderera pane chinhu chakagoverana, kana kuti password, kudzivirira kusvika. Chero ani anoziva chinyorwa cheWEP anogona kubatanidzwa nesezera risina mutambo. Pakanga pasina maitiro akavakirwa kuWEP kuti achinje chinangwa chacho, uye kune zvishandiso zvinogona kuparadzanisa hutu hweWEP mumaminitsi, naizvozvo hazvizotora kwenguva refu kuti munhu anorwisa awane WEP-yakavharidzirwa isina wire network.
Paunenge uchishandisa WEP zvingave zviri nani pane kushandiswa kusina kuvhara zvachose, hazvina kukwana pakudzivirira kambani yebazi. Chizvarwa chinotevera chekuvhara, WPA (Wi-Fi Protect Access), yakagadzirirwa kuongorora 802.1X-gwaro rinogonesa server, asi rinogonawo kufanana neWEP mu PSK (Pre-Shared Key) mode. Kukurukurirana kukuru kubva kuWEP kusvika kuWPA ndiko kushandiswa kweTKIP (Temporal Key Integrity Protocol), iyo inoshandura chinangwa chekudzivirira nzira dzekunyengera dzinoshandiswa kuputsa WEP encryption.
Kunyange WPA yakanga iri nzira yekubatsira mabhande kunyange zvakadaro. WPA yakanga iri kuedza ne wireless hardware uye vatengesi vepurogiramu kuti vashandise kudzivirirwa zvakakwana pavanenge vakamirira hurumende yepamusoro ye 802.11i. Nzira yakanyanya kunyanya kunyorwa ndiyo WPA2. IWPA2 encryption inopa nzira dzakaoma uye dzakachengeteka dzinosanganisira CCMP, iyo inobva paAES encryption algorithm.
Kuti uchengetedze nhepfenyuro isina tsvina kubva pakurambidzwa uye kudzivirira kusabvumirwa kusina kubvumirwa kunhare yako isina wire, WLAN yako inofanira kuiswa pamwe neWPA encryption, uye zvichida WPA2 encryption.
Wireless Authentication
Kunze kwokungonyora data dzisingabatsiri, WPA inogona kutarisana ne 802.1X kana RADIUS vimbiso dzemasevhisi kuti ipe nzira yakachengeteka yekudzora kuwanikwa kune WLAN. Apo WEP, kana WPA muPSK mode, inobvumira kuti munhu wese asina ruzivo rwakakodzera kana password, 802.1X kana RADIUS vimbiso inoda kuti vashandi vave nevhidhiyo yakakodzera yezita uye zvinyorwa zvepa password kana chidzidzo chakanaka kuti upinde mukati meusiterevhiti.
Zvinoda kuti kuvimbiswa kweWLAN kuwedzere kuchengeteka nekudzivirira kusvikirwa, asi kunopawo kugadzira miti uye nzira yekuongorora inofanirwa kuongorora kana chero chinokanganisa chinopfuurira. Kunyange zvazvo mutsara usina tsvina unobva pachigamba chakagoverwa unogona kuvhara MAC kana IP adresses, iyo ruzivo harubatsiri kana iri pakusarudza kuti chii chinokonzera dambudziko. Kuwedzera kwakavanzika uye kuvimbika kwakapiwa zvinowirirudzirwa, kana zvisingadiwi, nezvemishandiro akawanda ekuchengetedza zvigaro.
NeWPA / WPA2 uye 802.1X kana RADIUS kuvimbiswa server, masangano anogona kuenzanisa zviratidzo zvakasiyana-siyana zvekuvimbika, zvakadai seKerberos, MS-CHAP (Microsoft Challenge Handshake Authentication Protocol), kana TLS (Transport Layer Security), uye kushandisa shanduko credential authentication nzira dzakadai semasernames / passwords, zvitikiti, biometric kuvimbiswa, kana imwe-password password.
Nhare dzesimbi dzinogona kukura zvakanaka, kubudirira kubudirira uye kugadzira mitero yakawanda inodhura, asi kana isingashandisirwe zvakanaka inogonawo kuva Achill chitsitsinho chekuchengetedzwa kwenethiwekhi yako uye inoratidza kuti sangano rako rose rinopesana. Tora nguva yeku kunzwisisa njodzi, uye nzira yekuchengetedza nhare yako isina wire kuitira kuti sangano rako rive nehuwandu hwehutano hwehutachiona husina kushandiswa pasina kusimbisa mukana wekuchengetedzwa kwekuchengeteka.
