Ngakho yini i-firewall? Ithuluzi lapho umsebenzi wakhe uncike ngokugcwele kumnikazi we-PC, okungukuthi, ukuphepha kwikhompyutha kuzoqinisekiswa uma kwenzeka umsebenzisi enza izinqumo ezifanele. Ngakho-ke, kubalulekile ukugcina imithetho elandelayo: qapha imiyalezo yomlilo bese uyifunda ngokucophelela; Ukuze unikeze ukufinyelela kuphela kulezo zinhlelo ezidinga ngempela; Uma kukhona ukungabaza, kungcono ukuthi uphephe futhi unqande ukuxhumana.

Kuze kube yimanje, eziningi zokukhokha zomlilo ezikhokhelwayo nezikhululekile zakhiwe, eziphethwe ngokusebenza okufanayo futhi zihluke kuphela ku-interface.

Abakhiqizi balo banikeza abasebenzisi abaningi be-intanethi inguqulo ephelele ye-software yokuvikela ikhompyutha yakho ezinsongweni zangaphandle kanye nokuvuza kolwazi. Kumele kuthiwa yenzelwe abaqhubi bePC abavamile abangazi kahle kuzilungiselelo zenethiwekhi.

Iyini umlilo we-Comodo? Lolu hlelo oluncane aludingi izinsizakalo ezikhethekile, okukwazi ukubona izinhlelo zokusebenza ezingaba ngu-10 000 ezigabeni ezifana nokukhangisa, i-spyware nabanye. Phakathi kwezici zayo eziyinhloko yizinto ezilandelayo:

1. Kuyinto elula futhi eqondakalayo esibonakalayo se-"teapot".
2. Ukuhlinzeka ukuvikelwa emagciwane, izikripthi, ukuhlasela kwe-hacker.
3. Umsebenzi wezinhlelo kuWeb uhlale uqapha.
4. Ukulawula kwe-traffic on-line.
5. Ukuvuselela okuzenzakalelayo kohlelo.

"Komodo" iyi-firewall "ekhuluma" nomsebenzisi ngokusebenzisa amawindi e-pop-up nemilayezo ecacile ngangokunokwenzeka futhi kuyo yonke imininingwane imininingwane mayelana nokuthi kwenzekani inikezwa.
