Izinhlelo zokuvikela

Firewalls - ngesikhwama esivikelayo isofthiwe ekhethekile izinhlelo (izinhlelo zokuvikela) ukuvimbela okungagunyaziwe igciwane Inthanethi kuhlasela, kanye nekwakha isithiyo njengoba ikhompyutha olulodwa, noma yonkana inethiwekhi zendawo ezivela ezinonya Trojans. Ngesisekelo injongo yabo eyinhloko - ungalahlekelwa amaphakethe osolisayo, izinhlelo ezinjalo babe elinye igama - izihlungi. Namuhla, abakhiqizi abadume kunabo bonke zokuvikela zokuzivikela zimi kanje: ZyXEL, firewall, TrustPort Ubude Ukuvikelwa, Alamu Yomkhawulo, D-Link, Computing Secure, Watchguard Technologies.

Ilungiselela izinhlelo zokuvikela

Firewalls zilungiswa ngesandla, okuyinto eyenza enemininingwane Ukuvikelwa ukufakwa. Esinye sezici ezibaluleke kakhulu - antivirus ukubeka ngqo ye-USB ezisezingeni. Ecacisa izilungiselelo oyifunayo, usebenzisa isimiso esinjalo kungaba ukudala ukuzilawula ngokuphelele input bese okukhipha kunethiwekhi yasendaweni futhi wonke amadivayisi e-elekthronikhi ngezithako zawo.

Ngokufeza ukulungiswa ibhukwana isihlangu kwenye amakhompyutha akwinethiwekhi, kungenzeka ngesikhathi lemfisha ukudlulisela izilungiselelo ngomumo eyenziwe kwenye inethiwekhi amayunithi. Ngaphezu kwalokho, Synchronicity wokusebenza kuqinisekiswa ngisho noma wireless lwenethiwekhi. Ukubeka imingcele edingekayo yokusebenza firewall kuthatha isikhathi, kodwa uma umphatha usulu, imikhawulo wokuphepha ungaphendulwa uvimbe abanye ezidingekile isevisi.

izici engeziwe kwenethiwekhi izihlungi

Kukhona izinhlelo zokuvikela ukuthi kungenziwa amisiwe for ukuvikelwa okungeziwe la ukungabandakanywa ezinhlelweni ezithize futhi izicelo. Ngokwesibonelo, ukuvimbela nokugenca "Control Zomzali" bese usetha "ogaxekile." Ukusetha i-ukufinyelela ku-intanethi futhi ilungelo ukusebenza inethiwekhi avaliwe for Uhlelo ngalunye futhi isicelo ingachazwa ngokwehlukile. isihlungi Fieldbus ukulawula ukufinyelela kumasayithi zingase zigade kuphuma scan ukuhlunga Web-okuqukethwe. Futhi-ke uyakwazi ukuvimba ukufinyelela kusuka osolisayo IP-ikheli, ukuze sikwazise noma Bebona imizamo kuhlasela.

Izinhlobo izibhulamlilo izibhulamlilo

Firewalls zihlukaniswe lezi zinhlobo ezilandelayo:

- firewall zendabuko, okwenza inikeza gqwa ukufinyelela ukuthumela nokwamukela amaphakethe;

- kweseshini firewall ethungatha amaseshini ngabanye elisungulwe phakathi izicelo batfole Ukuvalwa ngesikhathi esifanele amaphakethe uncertified esetshenziswa ngokuvamile nokugenca, oluyimfihlo idatha ukuskena, njll;..

- UKUHLAZIYWA firewall kokwenza zokuhlunga esekelwe ukuhlaziya ulwazi yangaphakathi e iphakethe, kulandele uvimba we Trojans abaziwayo;

- firewall hardware, ifakwe namafutha esakhelwe kwenza kanyekanye nsada zokuvimbela (IPS), unqulo wesi arab ukuskena, ekuvimbeleni okungagunyaziwe abasebenzisi ngaphakathi senethiwekhi ezimele, futhi i-VPN-yokufihla, kanye ukusebenza ngaphezulu ufeze lokuvikela.

izinyathelo zokuqapha

Ukuqinisekisa izinga isofthiwe nokunokwethenjelwa Ukuvikelwa inethiwekhi ngokumelene intrusions okungagunyaziwe kanye nokugenca, ukufakwa ngaleso ISIZINDA inethiwekhi kuphela eqinisekisiwe lokuvikela. Okwamanje, izenzo zomthetho enikeziwe isitifiketi FSTEC, Gazpromcert futhi e-FSB. Ngokwesibonelo, isitifiketi FSTEC eziqinisekisa ukuthi isihlungi firewall uhambisana nazo zonke izimfuneko babeka phansi ingxenye yokuqala idokhumenti State Technical Commission of Russia. A izitifiketi FSB abonisa ukuthi izinhlelo ukuvikelwa uhlelo oluhambisana Russian State Standard izimfuneko ukuphepha nobumfihlo bolwazi.
