Kodi Bypass ndi chiyani?
Network Security Equipment imagwiritsidwa ntchito kwambiri pakati pa maukonde awiri kapena angapo, monga pakati pa netiweki yamkati ndi netiweki yakunja. The Network Security Equipment kudzera kusanthula paketi paketi maukonde, kudziwa ngati pali kuopseza, pambuyo kukonzedwa malinga ndi malamulo ena routing kutumiza paketi kupita kunja, ndipo ngati zida zotetezera maukonde zinasokonekera, Mwachitsanzo, pambuyo kulephera mphamvu kapena ngozi. , magawo a netiweki olumikizidwa ku chipangizocho amachotsedwa wina ndi mnzake. Pankhaniyi, ngati netiweki iliyonse iyenera kulumikizidwa wina ndi mnzake, ndiye kuti Bypass iyenera kuwonekera.
Ntchito ya Bypass, monga momwe dzinalo limatanthawuzira, imathandizira maukonde awiriwa kuti agwirizane popanda kudutsa dongosolo la chipangizo chachitetezo cha netiweki kudzera mumtundu wina woyambitsa (kulephera kwamagetsi kapena kuwonongeka). Chifukwa chake, chipangizo chachitetezo cha maukonde chikalephera, maukonde olumikizidwa ndi chipangizo cha Bypass amatha kulumikizana wina ndi mnzake. Inde, chipangizo cha intaneti sichimayendetsa mapaketi pa intaneti.
Kodi mumayika bwanji Bypass Application Mode?
Bypass imagawidwa m'njira zowongolera kapena zoyambitsa, zomwe zili motere
1. Kuyambitsidwa ndi magetsi. Munjira iyi, ntchito ya Bypass imathandizira pomwe chipangizocho chidazimitsidwa. Ngati chipangizocho chiyatsidwa, ntchito ya Bypass idzayimitsidwa nthawi yomweyo.
2. Kulamulidwa ndi GPIO. Mukalowa mu OS, mutha kugwiritsa ntchito GPIO kugwiritsa ntchito madoko ena kuti muwongolere kusintha kwa Bypass.
3. Kulamulira ndi Watchdog. Izi ndizowonjezera mode 2. Mukhoza kugwiritsa ntchito Watchdog kuti muyang'ane kuthandizira ndi kulepheretsa pulogalamu ya GPIO Bypass kuti muwongolere mawonekedwe a Bypass. Mwanjira iyi, ngati nsanja ikugwa, Bypass ikhoza kutsegulidwa ndi Watchdog.
Muzogwiritsira ntchito, maiko atatuwa nthawi zambiri amakhalapo nthawi imodzi, makamaka mitundu iwiri ya 1 ndi 2. Njira yogwiritsira ntchito ndi: pamene chipangizocho chikuzimitsidwa, Bypass imathandizidwa. Chidacho chikayatsidwa, Bypass imathandizidwa ndi BIOS. BIOS ikatenga chipangizocho, Bypass imayatsidwabe. Zimitsani Bypass kuti pulogalamuyo igwire ntchito. Panthawi yonse yoyambira, palibe kulumikizidwa kwa netiweki.
Kodi Mfundo Yoyendetsera Bypass ndi chiyani?
1. Mulingo wa Hardware
Pamlingo wa hardware, ma relay amagwiritsidwa ntchito makamaka kukwaniritsa Bypass. Ma relay awa amalumikizidwa ndi zingwe zama siginecha zamadoko awiri a Bypass network. Chithunzi chotsatira chikuwonetsa njira yogwirira ntchito ya relay pogwiritsa ntchito chingwe chimodzi cha chizindikiro.
Tengani choyambitsa mphamvu monga chitsanzo. Pankhani ya kulephera kwa mphamvu, chosinthira mu relay chidzalumphira ku dziko la 1, ndiko kuti, Rx pa RJ45 mawonekedwe a LAN1 idzalumikizana mwachindunji ndi RJ45 Tx ya LAN2, ndipo chipangizocho chikayatsidwa, chosinthira chidzagwirizana. kulumikiza ku 2. Mwa njira iyi, ngati kulankhulana maukonde pakati LAN1 ndi LAN2 chofunika, Muyenera kutero kudzera ntchito pa chipangizo.
2. Mapulogalamu a Mapulogalamu
Pagulu la Bypass, GPIO ndi Watchdog amatchulidwa kuti aziwongolera ndikuyambitsa Bypass. M'malo mwake, njira ziwirizi zimagwiritsa ntchito GPIO, ndiyeno GPIO imayang'anira kutumizirana ma hardware kuti idumphe. Mwachindunji, ngati GPIO yofananira yakhazikitsidwa pamlingo wapamwamba, relay idzalumphira ku 1 mofanana, pamene chikho cha GPIO chikayikidwa pamlingo wochepa, kubwereza kudzalumphira ku 2 mofanana.
Kwa Watchdog Bypass, imawonjezedwanso Watchdog control Bypass pamaziko a ulamuliro wa GPIO pamwambapa. Woyang'anira akayamba kugwira ntchito, khazikitsani zomwe zingalambalale BIOS. Dongosolo limayendetsa ntchito ya watchdog. Woyang'anira akayamba kugwira ntchito, njira yolumikizira doko ya netiweki imayatsidwa ndipo chipangizocho chimalowa m'malo olambalala. Ndipotu, Bypass imayang'aniridwanso ndi GPIO, koma pakadali pano, kulembedwa kwa magawo otsika ku GPIO kumachitidwa ndi Watchdog, ndipo palibe mapulogalamu owonjezera omwe amafunikira kuti alembe GPIO.
Ntchito ya Hardware Bypass ndi ntchito yovomerezeka yazinthu zotetezedwa pamaneti. Chipangizocho chikazimitsidwa kapena kugwa, madoko amkati ndi akunja amalumikizidwa kuti apange chingwe cha netiweki. Mwanjira iyi, kuchuluka kwa data kumatha kudutsa mwachindunji pa chipangizocho popanda kukhudzidwa ndi momwe chipangizocho chilili.
Kugwiritsa Ntchito Kwambiri (HA):
Mylinking™ imapereka mayankho awiri opezeka kwambiri (HA), Active/Standby ndi Active/Active. Kuyimilira kwa Active (kapena yogwira / kungokhala) ku zida zothandizira kuti zipereke kulephera kuchokera ku zida zoyambira mpaka zosunga zobwezeretsera. Ndipo Active/Active Deployed to redundant links to provide failover pamene chida chilichonse Chogwira chikanika.
Mylinking™ Bypass TAP imathandizira zida ziwiri zosafunikira zapaintaneti, zitha kuyikidwa mu Active/Standby yankho. Imodzi imakhala ngati chipangizo choyambirira kapena "Yogwira". Chipangizo choyimilira kapena "Passive" chimalandirabe kuchuluka kwa magalimoto mu nthawi yeniyeni kudzera mu mndandanda wa Bypass koma sichimaganiziridwa ngati chida chapakati. Izi zimapereka "Hot Standby" redundancy. Ngati chipangizo chogwira ntchito chalephereka ndipo Bypass TAP ikasiya kulandira kugunda kwa mtima, chipangizo choyimiliracho chimangotenga malo ngati chida choyambirira ndikubwera pa intaneti nthawi yomweyo.
Ndi Ubwino Wotani womwe mungapeze potengera Bypass yathu?
1-Gawirani kuchuluka kwa magalimoto musanayambe komanso pambuyo pa chida chapakati (monga WAF, NGFW, kapena IPS) ku chida chakunja
2-Kuwongolera zida zingapo zapaintaneti nthawi imodzi kumathandizira zosungika zachitetezo ndikuchepetsa zovuta zama netiweki
3-Amapereka zosefera, kuphatikizira, ndi kusanja kwapaintaneti
4-Kuchepetsa chiopsezo cha nthawi yosakonzekera
5-Kulephera, kupezeka kwakukulu [HA]
