Me pēhea te whakatū i tētahi Pātūahi: He Aratohu Katoa mō te Haumarutanga o tō Whatunga
He wāhanga nui ngā pareārai ahi o ngā whatunga rorohiko o ēnei rā, e mahi ana hei kaitiaki tatau hei tiaki i ngā mōhiohio tairongo mai i ngā tūmomo riri me ngā whakaeke ipurangi. He mea nui te whirihora tika i tētahi pareārai ahi hei pupuri i te pono me te muna o ngā raraunga. Ka matapakihia e tēnei tuhinga ngā mahi me ngā tikanga pai mō te whirihora i tētahi pareārai ahi hei whakarite i te tiakitanga pai mō tō whatunga.
He aha te Pātūahi?
Ko te pareārai he taputapu, he pūmanawa rānei i hangaia hei aroturuki me te whakahaere i ngā waka whatunga, e haere mai ana, e haere atu ana hoki, i runga i ngā ture haumarutanga kua whakatūria. Ka āwhina ngā pareārai ki te aukati i te urunga kore mana ki ngā pūnaha whatunga, me te tiaki hoki i ngā tūmomo riri ipurangi, pērā i te pūmanawa kino, ngā whakaeke DDoS, me ngā nganatanga whakauru.

4. Whirihoranga Pātūahi Taketake
– Wāhitau IP me ngā Tautuhinga Whatunga: Tautapahia he wāhitau IP tūmau ki te pareārai ahi, ā, whakatakotoria ngā tawhā whatunga pēnei i te kopare whatunga iti me te kēti taunoa kia rite ki ō hiahia whatunga.
– Ngā Ture Kaupapahere Taketake: Waihangahia he kaupapahere taketake e tautuhi ana i ngā mea e whakaaetia ana me ngā mea e rāhuitia ana. Hei tauira, āraia ngā waka katoa mai i ngā pūtake kāore i te mōhiotia, ā, whakaaetia anake ngā tono me ngā ratonga pono.
5. Whakatakotoria ngā Ture me ngā Kaupapa Here Haumarutanga
– Rārangi Mā me te Rārangi Pango: Tautuhia he rārangi o ngā wāhitau IP, o ngā rohe rānei e whakaaetia ana (rārangi mā) me te āraia (rārangi pango).
– Tātari Ihirangi: Whakamahia he tātari hei aukati i te urunga atu ki ngā ihirangi kino, kāore rānei e hiahiatia ana pērā i ngā pae hītinihanga me ngā pae pūmanawa kino.
– Te Ārai i te Urupare: Whakahohehia te pūnaha ārai urutomo (IPS) kia kitea me te aukati i ngā nganatanga urutomo.
6. Te Wehewehenga Whatunga
He taahiraa nui te wehewehenga whatunga i roto i te whakatūnga pareārai, e āwhina ana ki te wehewehe i tētahi whatunga ki ngā wāhanga, ki ngā rohe rānei me ngā ture haumarutanga rerekē. Hei tauira, ka taea e koe te waihanga rohe motuhake mō te whatunga rohe ā-rohe (LAN), te whatunga manuhiri, me te whatunga Rohe Whakakore Hiko (DMZ).
