Zagawidwa posachedwa m’gulu lathu. Ndemangazi zidakweza vuto lalikulu lachitetezo chazidziwitso cha USB pa IP hardware mayankho, zomwe zimatidetsa nkhawa kwambiri.
Kotero, choyamba, tiyeni tisankhe pazochitika zoyamba.
- Makiyi ambiri achitetezo apakompyuta.
- Ayenera kupezeka kuchokera kumadera osiyanasiyana.
- Tikungoganizira mayankho a USB pa IP okha ndipo tikuyesera kuteteza yankholi potengera njira zina zamagulu ndi zaukadaulo (sitikuganiziranso za njira zina).
- Pakatikati mwa nkhaniyi, sindifotokoza momveka bwino zitsanzo zowopseza zomwe tikuziganizira (mutha kuwona zambiri mu ), koma ndifotokoza mwachidule mfundo ziwiri. Sitiphatikiza uinjiniya wamagulu ndi zochita zoletsedwa za ogwiritsa ntchito pawokha. Tikulingalira za mwayi wopeza zida za USB mosaloledwa kuchokera pa netiweki iliyonse popanda zidziwitso zanthawi zonse.
Kuonetsetsa chitetezo chopezeka pazida za USB, njira zamabungwe ndiukadaulo zatengedwa:
1. Njira zotetezera bungwe.
USB yoyendetsedwa pa IP hub imayikidwa mu kabati ya seva yotsekeka yapamwamba kwambiri. Kufikirako mwakuthupi kumasinthidwa (njira yolowera kumalo komweko, kuyang'anira makanema, makiyi ndi ufulu wopeza anthu ochepa kwambiri).
Zida zonse za USB zomwe zimagwiritsidwa ntchito m'gululi zimagawidwa m'magulu atatu:
- Zovuta. Ma signature a digito azachuma - ogwiritsidwa ntchito molingana ndi malingaliro a mabanki (osati kudzera pa USB pa IP)
- Zofunika. Siginecha zamagetsi zamagetsi zamapulatifomu ogulitsa, ntchito, kutuluka kwa e-document, malipoti, ndi zina zambiri, makiyi angapo apulogalamu - amagwiritsidwa ntchito pogwiritsa ntchito USB yoyendetsedwa pa IP hub.
- Osatsutsa. Makiyi angapo a mapulogalamu, makamera, ma drive angapo ang'onoang'ono ndi ma disks okhala ndi chidziwitso chosafunikira, ma modemu a USB - amagwiritsidwa ntchito pogwiritsa ntchito USB yoyendetsedwa pa IP hub.
2. Miyezo yachitetezo chaukadaulo.
Kufikira kwa netiweki ku USB yoyendetsedwa pa IP hub kumangoperekedwa mkati mwa subnet yokhayokha. Kufikira ku subnet yokhayokha kumaperekedwa:
- kuchokera ku famu ya terminal server,
- kudzera VPN (chiphaso ndi mawu achinsinsi) ku chiwerengero chochepa cha makompyuta ndi laputopu, kudzera VPN amapatsidwa maadiresi okhazikika,
- kudzera mu ngalande za VPN zolumikiza maofesi achigawo.
Pa USB yoyendetsedwa pa IP hub DistKontrolUSB, pogwiritsa ntchito zida zake zonse, ntchito zotsatirazi zimakonzedwa:
- Kuti mupeze zida za USB pa USB pa IP hub, kubisa kumagwiritsidwa ntchito (kubisa kwa SSL kumayatsidwa pakatikati), ngakhale izi zitha kukhala zosafunikira.
- "Kuletsa kupezeka kwa zida za USB ndi adilesi ya IP" kumakonzedwa. Kutengera adilesi ya IP, wogwiritsa ntchito amapatsidwa kapena satha kupeza zida za USB zomwe wapatsidwa.
- "Kuletsa kulowa padoko la USB polowera ndi mawu achinsinsi" yakonzedwa. Chifukwa chake, ogwiritsa ntchito amapatsidwa mwayi wopeza zida za USB.
- "Kuletsa kugwiritsa ntchito chipangizo cha USB polowera ndi mawu achinsinsi" adasankhidwa kuti asagwiritsidwe ntchito, chifukwa Makiyi onse a USB amalumikizidwa ku USB kupita ku IP hub kwamuyaya ndipo sangathe kusunthidwa kuchokera kudoko kupita kudoko. Ndizomveka kuti tipatse ogwiritsa ntchito mwayi wopita ku doko la USB ndi chipangizo cha USB chomwe chayikidwamo kwa nthawi yayitali.
- Kuyatsa ndi kuzimitsa madoko a USB kumachitika:
- Kwa makiyi a mapulogalamu ndi zikalata zamagetsi - pogwiritsa ntchito ndondomeko ya ntchito ndi ntchito zomwe zapatsidwa (makiyi angapo adakonzedwa kuti atsegule pa 9.00 ndikuzimitsa pa 18.00, chiwerengero kuchokera ku 13.00 mpaka 16.00);
- Kwa makiyi a nsanja zamalonda ndi mapulogalamu angapo - ndi ogwiritsa ntchito ovomerezeka kudzera pa WEB mawonekedwe;
- Makamera, ma drive angapo ang'onoang'ono ndi ma disks okhala ndi chidziwitso chosafunikira nthawi zonse amayatsidwa.
Tikuganiza kuti bungwe ili lofikira pazida za USB limatsimikizira kugwiritsidwa ntchito kwawo kotetezeka:
- kuchokera kumaofesi achigawo (moyenera NET No. 1...... NET No. N),
- pamakompyuta ochepa ndi ma laputopu olumikiza zida za USB kudzera pa intaneti yapadziko lonse lapansi,
- kwa ogwiritsa ntchito omwe amasindikizidwa pa ma seva ogwiritsira ntchito terminal.
M'mawuwa, ndikufuna kumva njira zenizeni zomwe zimawonjezera chitetezo chazidziwitso chopereka mwayi wapadziko lonse ku zida za USB.
