Ukubaluleka Kokunakekelwa Kwenethiwekhi
Esikhathini sanamuhla sedijithali, amanethiwekhi ekhompyutha ayinsika cishe yayo yonke imisebenzi yenhlangano—kusukela ekuxhumaneni nge-imeyili kanye nokufinyelela kwezicelo zebhizinisi kuya ekuthengisweni kwezezimali kuya enkonzweni yamakhasimende. Lapho inethiwekhi ingasebenzi kahle, umthelela awuzwakali nje yithimba le-IT, kodwa yiwo wonke umkhakha: umsebenzi uyaphazamiseka, izinsizakalo ziyaphazamiseka, umkhiqizo uyancipha, ngisho nedumela lenkampani lingathinteka. Ngakho-ke, ukulungiswa kwenethiwekhi akuseyona inketho kodwa kuyisidingo esibalulekile okumele senziwe njalo nangendlela ehleliwe.
Ukuqonda Ukugcinwa Kwenethiwekhi
Ukugcinwa kwenethiwekhi kuwuchungechunge lwemisebenzi eyenziwa ukuqinisekisa ukuthi inethiwekhi ihlala izinzile, iphephile, futhi isebenza kahle kakhulu. Le misebenzi ihlanganisa ukuqapha, izibuyekezo zesofthiwe ne-firmware, ukuhlolwa kwehadiwe, ukuphathwa kokucushwa, kanye nokuvimbela kanye nokuphendula kokungasebenzi. Ukugcinwa kwayo kuhilela nokubhala njalo kanye nokuhlola ukuqinisekisa ukuthi inethiwekhi ingathuthuka ngokwezidingo zenhlangano.
Ngokuvamile, ukulungiswa kwenethiwekhi kuhlukaniswe izinhlobo ezimbili: ukuvimbela kanye nokulungisa. Ukuvimbela kugxila ekuvimbeleni izinkinga ngaphambi kokuba zenzeke, njengokwenza izibuyekezo zesistimu kanye nokuqapha ithrafikhi. Ukulungiswa kokulungisa kwenziwa ngemva kokuphazamiseka, njengokulungisa iswishi eyonakele noma ukuxazulula uxhumano lwe-inthanethi oluwile.
Kungani Ukugcinwa Kwenethiwekhi Kubaluleke Kangaka?
1. Ukugcina Ukutholakala Kwesevisi (Isikhathi Sokusebenza)
Enye yezinhloso eziyinhloko zokugcinwa kwenethiwekhi ukuqinisekisa ukutholakala okuqhubekayo kwezinsizakalo zenethiwekhi. Ngisho nemizuzu embalwa yokungasebenzi ingaba nomthelela omkhulu, ikakhulukazi ezinkampanini ezithembele ezinhlelweni eziku-inthanethi njenge-e-commerce, izinsizakalo zebhange, noma izibhedlela. Ngokulungiswa okuhleliwe, ukuphazamiseka okungenzeka kungatholakala kusenesikhathi, isibonelo, lapho amadivayisi eqala ukubonisa izimpawu zokushisa ngokweqile noma lapho i-bandwidth igcwala ngokweqile ngenxa yokusetshenziswa okwengeziwe.
Ukuqapha amahora angu-24 ngosuku, izinsuku ezingu-7 ngesonto, kanye nezinhlelo zezaziso ezizenzakalelayo kungasiza amaqembu e-IT ukuthi aphendule ngaphambi kokuba abasebenzisi babhekane nokuphazamiseka. Ngenxa yalokho, ukusebenza kuhlala kubushelelezi futhi ukuzethemba komsebenzisi kuyanda.
2. Khulisa Ukuphepha Futhi Unciphise Ingozi Yokuhlaselwa
Izinsongo ze-cyber zishintsha njalo: i-malware, i-ransomware, i-phishing, ngisho nokuhlasela kwe-DDoS kungahlasela noma nini. Ukuhlasela okuningi okuphumelelayo kungenxa yezinhlelo eziphelelwe yisikhathi noma ukucushwa kwenethiwekhi okubuthakathaka. Ukugcinwa kwenethiwekhi kudlala indima ebalulekile ekuvaleni lezi zikhala zokuphepha.
Ezinye izinyathelo ezibalulekile zokugcina ukuphepha kwenethiwekhi zifaka phakathi ukubuyekeza ama-patches okuphepha, ukuhlola abasebenzisi namalungelo okufinyelela, ukushintsha amaphasiwedi njalo, kanye nokulungiselela kahle ama-firewall. Ngaphezu kwalokho, ukusebenzisa ukuhlukaniswa kwenethiwekhi nokusebenzisa ama-VPN ukuze kufinyelelwe kude nakho kuyimikhuba evamile. Ngale ndlela, ingozi yokwephulwa kwedatha nokulahlekelwa yizimali ingancishiswa.
3. Gcina Ukusebenza Okuhle Kwenethiwekhi
Ngokuhamba kwesikhathi, inani labasebenzisi, amadivayisi, kanye nezinhlelo zokusebenza kunethiwekhi livame ukwanda. Ngaphandle kokulungiswa, inethiwekhi eyayishesha ekuqaleni ingaba yimbi ngenxa yomthwalo owandisiwe. Izinkinga ezifana nokubambezeleka okuphezulu, ukulahleka kwephakethe, kanye nokuvinjelwa komkhawulokudonsa kungaphazamisa imisebenzi yansuku zonke.
Ukulungiswa kusiza ekuboneni imithombo yokwehla kwejubane, njengamadivayisi enethiwekhi agcwele ngokweqile, ama-topology angasebenzi kahle, noma ukucushwa kwe-QoS (Ikhwalithi Yesevisi) okungafanele. Ngokuhlolwa kokusebenza okuvamile, izinhlangano zingenza ukuthuthukiswa noma ukulungiswa ngaphambi kokuba izinkinga zibe yizinkinga ezinkulu.
4. Nciphisa Izindleko Zokulungisa kanye Nokulahlekelwa Kokusebenza
Ukulungisa okuvimbelayo kuvame ukubiza kancane kunokulungisa okuphuthumayo. Uma kungalashwa, ukwehluleka kwemishini kungaholela ekuphazamisekeni okukhulu kakhulu futhi kulimaze neminye imishini. Isibonelo, uhlelo lokupholisa igumbi leseva olungakahlolwa lungabangela amazinga okushisa aphezulu futhi lufinyeze isikhathi sokuphila samaswishi, ama-router, noma amaseva.
Ngaphezu kwezindleko zemishini, isikhathi sokungasebenzi siphinde sibe nezindleko ezingaqondile ezifana namathuba okuthengisa alahlekile, ukubambezeleka komsebenzi, kanye nezikhalazo zamakhasimende. Ngohlelo lokulungisa oluhlelekile kahle, izinhlangano zingonga izindleko zesikhathi eside futhi zigweme ukulahlekelwa okukhulu kokusebenza.
5. Isekela Ukwanda Nokuhlela Intuthuko
Inethiwekhi enhle ayigcini nje ngokusebenza namuhla, imayelana nokuhlangabezana nezidingo zesikhathi esizayo. Ukugcinwa kwenethiwekhi kuhlinzeka ngemininingwane yomlando—njengezindlela zokusetshenziswa kwe-bandwidth, amazinga omthwalo wedivayisi, kanye namaphethini ethrafikhi—engasetshenziswa njengesisekelo sokuhlela intuthuko.
Ngokusekelwe kulolu lwazi, amaqembu e-IT anganquma ukuthi kufanele afake nini izindawo zokufinyelela, ashintshe ama-router anomthamo ophezulu, noma athuthukise amaphakheji e-inthanethi. Ngamanye amazwi, ukulungiswa kusiza izinhlangano ukuba zikhule ngaphandle kokubhekana nezinkinga zenethiwekhi njalo lapho isidingo sikhula.
Izingxenye Eziyinhloko Ekunakekelweni Kwenethiwekhi
Ukugcinwa kwenethiwekhi kuhlanganisa izici ezahlukene ezihlobene, okuhlanganisa:
1. Ukuqapha Inethiwekhi
Gada ithrafikhi, ukusetshenziswa komkhawulokudonsa, kanye nesimo sedivayisi ngesikhathi sangempela usebenzisa amathuluzi okuqapha. Umgomo ukuthola ngokushesha izinto ezingavamile.
2. Izibuyekezo Zesistimu Ne-Firmware
Ama-router, amaswishi, izindawo zokufinyelela, kanye nama-firewall ngokuvamile anezibuyekezo ze-firmware ezithuthukisa ukuphepha nokuzinza.
3. Ukuhlolwa Kwehadiwe
Lokhu kufaka phakathi ukuhlola izintambo, ama-switch port, amamojula e-SFP, ama-UPS, kanye nesimo se-server rack. Umonakalo ongokwenyama uvame ukuba umthombo wezinkinga okunzima ukuzibona ngaphandle kokuhlolwa njalo.
4. Ukuphathwa Kokucushwa kanye Nesipele
Ukucushwa kwedivayisi yenethiwekhi kudinga ukubhalwa phansi futhi kwenziwe isipele. Lokhu kuvumela ukululama okusheshayo uma kwenzeka umonakalo noma ukulungiselelwa okungalungile.
5. Ukuhlolwa Kokuphepha kanye Nokufinyelela Komsebenzisi
Ukuhlola ama-akhawunti angasebenzi, imikhawulo yokufinyelela, kanye nezilungiselelo zenqubomgomo yenethiwekhi ukuze kuvinjelwe ukusetshenziswa kabi.
6. Imibhalo kanye Nokubika
Zonke izenzo zokulungisa kufanele ziqoshwe: okwenziwe, nini, kanye nemiphumela. Lokhu kubalulekile ekuhlolweni nasekubhekiseleni kukho uma kuba nezinkinga zesikhathi esizayo.
Izibonelo Zemiphumela Uma Inethiwekhi Ingagcinwa
Ngaphandle kokulungiswa, amanethiwekhi angabhekana nezinkinga ezahlukahlukene: ukwehla kokuxhumeka njalo, ukwehla kwesivinini se-inthanethi, ukumiswa kwamadivayisi njalo, kanye nezingozi zokuphepha ezandayo. Ngezinga elikhulu, izinkampani zingabhekana nokuvuza kwedatha yamakhasimende noma ukuphazamiseka kwezinsizakalo ezibalulekile. Ngisho nezinkinga ezilula njengezintambo ezikhululekile noma ubuningi bezindawo zokufinyelela kungaba yizikhalazo zansuku zonke zomsebenzisi uma zingaxazululwa njalo.
Isiphetho
Ukugcinwa kwenethiwekhi kuyindlela ebalulekile yokugcina ukuzinza, ukuphepha, kanye nokusebenza kwengqalasizinda ye-IT. Ngokugcinwa okufanele, izinhlangano zingaqinisekisa ukusebenza isikhathi eside, zivimbele ukuhlaselwa kwe-cyber, zithuthukise ukusebenza kwenethiwekhi, zonge izindleko, futhi zilungiselele ukwanda kwesikhathi esizayo. Ngokuthembela okwandayo kubuchwepheshe, ukulungiswa kwenethiwekhi kuyisihluthulelo sokugcina ukuthembeka kwesistimu nokusekela ukuqhubeka kokusebenza okuqhubekayo.
Uma kwenziwa njalo nangendlela ehleliwe—ngokuqapha, ukuvuselela, ukuhlolwa kwezokuphepha, ukuhlolwa kwamadivayisi, kanye namadokhumenti—ukulungiswa kwenethiwekhi kuzosiza izinhlangano ukuthi zisebenze kahle futhi zilungele ukubhekana nezinselele zedijithali ezishintsha njalo.
