Izixhobo zomlilo zokhuseleko zikhusela intambo yonxibelelwano evela kwi-intrusions engenayo
I-firewall yenethwekhi ikhusela inethiwekhi yecomputer ekufikeleleni okungagunyaziswanga. Ingaba yinkqubo ye- hardware , inkqubo yesofthiwe, okanye ukudibanisa ezimbini.
Izixhobo zomlilo zomnatha zilinda inethiwekhi yekhomputha yangaphakathi ngokubhekiselele ekungeneni okungalunganga ukusuka ngaphandle, njengeziko le-malware elifakwe kwi-malware okanye amachwephelo avulelekileyo anethiwekhi . Unokuzifumana naphina inethwekhi isetyenzisiweyo, njengasekhaya, isikolo, ishishini, okanye i- intranethi .
I-firewall yenethiwekhi ingaqwalaselwa ukukhawulela ukungena kubangaphakathi kubasebenzisi bangaphakathi, njengokuba kukho ukulawulwa kwabazali okanye ukuvalelwa kwendawo yokusebenzela, zombini ezo zivimbela ukufikelela ekungcakazelweni kwewebhu kunye nabantu abadala, phakathi kweminye imixholo eninzi.

I-firewall inokukhubaza izicelo ezithile ukusuka ekufikeleleni kwinethiwekhi, ukuvimba ii-URL ekulayisheni, nokukhusela i-traffic ngokusebenzisa ezinye izichwephelo zenethiwekhi.
Ezinye izitshixo zomlilo zingasetyenziselwa kwimodi apho zivimba yonke into uze uvumele ngokucacileyo ukufikelela nganye. Le yindlela enye yokuvimba yonke into kwinethiwekhi ukwenzela ukuba ukwazi ukusetha ngesandla ngokukhusela ukukhusela izinto ezinxulumene nenethiwekhi.
I-Firewall Software kunye ne-Broadband Routers
Iimveliso ezininzi zeteknoloji zasekhaya ziquka ukuxhaswa kwe-firewall inkxaso. Uqwalaselo lolawulo lwala ma rou routa luquka ukhetho lwe-firewall. Ii-firewall ziyakhutshwa (zikhutshaziwe), okanye ziyakusetyenziselwa ukucoca ezinye iintlobo zendlela yokuthungelwano kwimizila ebizwa ngokuba yi-firewall.
Iphulo: Bona indlela yokukhusela i-Firewall yakho engenaWindows Router ukuze ufunde kabanzi, kuquka ukujonga ukuba i-router isekela i-firewall.
Zininzi iinkqubo ze-firewall iinkqubo ezikhoyo ukuba ufake ngqo kwi- hard drive yekhomputha eyifunayo. Ezi zikhuni, kodwa zikhusela kuphela ikhompyutha eqhubayo; Izixhobo zomlilo zomnatha zikhusela yonke inethiwekhi. Njengomlilo womnatha womnatha, iifutha-fire based-firewalls zingakhubazeka, kwakhona .
Ukongezelela kwiiprogram ze-firewall ezizinikezelweyo ziinkqubo ze-antivirus ezihlala ziquka i-firewall eyakhelwe ngaphakathi kunye nokufakela.
Iifowuni zomnatha kunye neeNkonzo zeeNkonzo
Olunye uhlobo oluqhelekileyo lwe-firewall yenethiwekhi ngumncedisi we-proxy. Iiseva ze proxy zisebenza njengomlambanisi phakathi kweekhomputha zangaphakathi kunye noxhumo lwangaphandle ngokufumana kunye nokukhethiya iipakethi zedatha kumda womnatha.
Le mililo yomnatha inika kwakhona umlinganiselo owongezelelweyo wokhuseleko ngokufihla idilesi zangaphakathi ze- LAN kwi-intanethi ngaphandle. Kwimeko ye-firewall yomsebenzisi weproxy , izicelo zenethwekhi ezivela kubathengi abaninzi zivela kumntu ongaphandle njengoko zonke zivela kwidilesi enye yee-proxy idilesi.
