Zosasinthika, Zothandizira, ndi Zovomerezeka pa Zokonda pa Chipangizo cha Mawu

Chigawochi chili ndi malingaliro enaake a mawu omwe sanakhazikitsidwe ngati kasinthidwe otuluka m'bokosi. Nthawi zambiri amalangizidwa kuti ayang'ane zoikamo zomwe zikugwirizana ndi zosowa za netiweki ya WLAN ndi zomwe zimayendera. Nthawi zina, kusintha kosasinthika kumatha kuwononga magwiridwe antchito amtundu uliwonse.

Kupatula malingaliro enieni omwe angafunikire kuwunika mosamala, zosintha zambiri za chipangizocho zakonzedwa kale kuti zigwirizane ndi mawu. Pazifukwa izi, tikulimbikitsidwa kuti musunge zosintha ndikulola chipangizochi kuti chisinthire magawo osankhidwa a netiweki ya WLAN. Masinthidwe a chipangizo akuyenera kusintha pokhapokha ngati pali ma netiweki a WLAN (Wireless LAN controller (WLC), ma access point (AP)) omwe amalamula kuti zisinthidwe pazida zitheke kuti zilole kugwilizana koyenera.

Dziwani izi:

• Pairwise master key identifier (PMKID) ndiyozimitsa pachidacho mwachisawawa. Ngati kasinthidwe kanu kakonzedwe ka PMKID, yambitsani PMKID ndi kuletsa makiyi opezeka mwa mwayi (OKC).
• Gawo la Subnet Roam limakupatsani mwayi wosintha ma IP a netiweki ya mawonekedwe a WLAN pomwe netiweki yakonzedwa kuti ikhale ndi subnet yosiyana pa chizindikiritso chofananira cha service (ESSID).
• Pochita kusintha kwachangu (FT) (yomwe imadziwikanso kuti FT Over-the-Air), ngati Njira zina zosagwirizana ndi FT Fast Roaming Njira zitha kupezeka pa SSID yomweyo, onani Njira Zoyenda Mwachangu mu Table 5 ndi zolemba zogwirizana mu General WLAN Malangizo pa.
• Gwiritsani ntchito othandizira owongolera zida zam'manja (MDM) kuti musinthe zokonda. Gwiritsani ntchito mawonekedwe ogwiritsira ntchito (UI) kuti musinthe magawo ang'onoang'ono.
• Pamawu omvera, komanso pamapulogalamu aliwonse olumikizirana ndi kasitomala-odalira kwambiri, sizovomerezeka kugwiritsa ntchito mawonekedwe a batire ya Android (yomwe imadziwikanso kuti Doze Mode) pazida zowongolera zida. Kukhathamiritsa kwa batri kumasokoneza kulumikizana pakati pa mathero odalira ndi ma seva.
• Media access control (MAC) mwachisawawa:
• Kuchokera ku Android Oreo kupita mtsogolo, zida za Zebra zimathandizira mawonekedwe a MAC randomisation, omwe amathandizidwa mwachisawawa. Zimitsani kapena yambitsani izi kudzera pa MDM kapena kudzera pazinsinsi za Android Gwiritsani ntchito Chipangizo cha MAC:
• Ikayatsidwa m'mitundu ya Android 10 komanso m'mbuyomu, mtengo wa MAC wokhazikika umagwiritsidwa ntchito posanthula ma netiweki atsopano a Wi-Fi musanalumikizane ndi netiweki yomwe mukufuna (asanalumikizane chatsopano), komabe, sagwiritsidwa ntchito ngati adilesi ya MAC ya chipangizocho. . Adilesi ya MAC yolumikizidwa nthawi zonse imakhala adilesi yapakhomo ya MAC.
• Mukayatsidwa mu Android 11 kupita mtsogolo, mtengo wa MAC wosasinthika umagwiritsidwanso ntchito polumikizana ndi netiweki yomwe mukufuna. Mtengo wosasinthika ndi wapadera pa dzina lililonse la netiweki (SSID). Zimakhalabe chimodzimodzi pamene chipangizocho chikuyendayenda kuchokera ku AP imodzi ya netiweki yolumikizidwa kupita ku ma AP (ma) osiyanasiyana a netiweki yomweyo, ndi/kapena ikayenera kulumikizanso netiweki inayake itatha kulumikizidwa.
• Chiwonetsero cha MAC cha randomisation sichimakhudza momwe mawu amagwiritsidwira ntchito ndipo sikofunikira kuti muyimitse izi kuti muthetse mavuto. Komabe, muzochitika zina, kuyimitsa kungakhale kothandiza pakusonkhanitsa deta.

Tebulo ili m'munsiyi likuwonetsa zokonda, zothandizidwa, ndi zovomerezeka za mawu.
