Iindidi zooMlilo: Izibonelelo kunye nezinto ezingalunganga

Sele siyazi i Firewall Uluhlu lwenethiwekhi okanye ukucoca ipakethi, lixesha lokuba ufunde ngolunye uhlobo lweFirewall. Sithumela umaleko wesicelo okanye iGateway. Zizo ezo, njengoko igama labo libonisa, zisebenza phantsi kwenqanaba lesi-7 kumaleko esicelo semodeli ye-OSI (Vula iNkqubo yoQhagamshelo, eyimodeli eyenziwe yi-International Standard Organisation okanye i-ISO yonxibelelwano lwenethiwekhi zekhompyuter).

Inqanaba 7 libhekisa kwinqanaba elichaza, lihlalutya kwaye lihlole iinkqubo ezisetyenziswayo Ukutshintshiselana kwedatha, njengee-imeyile, iifayile ze-FTP, amaphepha ewebhu (i-HTTP), phakathi kwabanye. Oko kukuthi, balawula uhlobo lomgaqo oza kusetyenziswa. Umzekelo, ukufikelela kwamanye amaphepha ewebhu kunokuthintelwa kusetyenziswa esi sixhobo. Enye yezona ndawo zibalulekileyo zomlilo kule nkqubo yi-Sonicwall kunye ne-iTinySoft.

Sikwafumana ifayile ye Amatye omlilo, Ezizizo zifakwe kwikhompyuter njengesoftware, kwaye ucofe ulwazi phakathi kwekhompyuter kunye nenethiwekhi yonke.
Phakathi kwezibonelelo kunye nezinto ezingalunganga zokuba ne-firewall zezi zilandelayo:

Inzuzo:
ukuya. Ukukhuselwa kweenkcukacha zabucala: Chaza ukuba yeyiphi abasebenzisi benethiwekhi kwaye loluphi ulwazi umntu ngamnye azakufumana
b. Ukufikelela kokufikelela: Chaza ngokuthe ngqo iinkqubo ezisetyenziswayo
c. Ukukhuselwa kongenelelo: Kukhusela abantu bangaphandle ngokuthintela ukufikelela kwinethiwekhi.

Iingxaki:
ukuya. Ayikhuseli kuhlaselo olungadluli kwi-firewall.
b. Ayizikhuseli izoyikiso kunye nohlaselo lwabasebenzisi abangakhathaliyo.
c. Ayikhuseli ekukopisheni idatha ebalulekileyo ukuba ifunyenwe.
d. Ayikhuseli kuhlaselo lobunjineli kwezentlalo (uhlaselo kusetyenziswa iindlela ezisemthethweni. Umzekelo, umhlaseli unxibelelana nexhoba elizenza njengomsebenzi webhanki, kwaye acele ulwazi oluyimfihlo, umzekelo, iinkcukacha zekhadi letyala, phantsi kwesizathu sokuhlaziya ikhadi elichaziweyo)
