Ngophuhliso olukhawulezayo lwe-Intanethi, isoyikiso sokhuseleko lolwazi lwenethiwekhi luya lusiba lukhulu ngakumbi. Ke iintlobo ezahlukeneyo zezicelo zokhuseleko lolwazi zisetyenziswa ngakumbi nangakumbi. Ingaba izixhobo zolawulo lofikelelo lwemveli FW (Firewall) okanye uhlobo olutsha iindlela zokhuseleko oluphambili ngakumbi ezifana inkqubo yokuthintela ukungena (IPS), iqonga Ulawulo isoyikiso ezimanyeneyo (UTM), Anti-ukukhanyela inkqubo yokuhlasela (Anti-DDoS), Anti -span Isango, i-DPI edibeneyo yokuchonga i-Traffic Identification and Control System, kunye nezixhobo ezininzi zokhuseleko / izixhobo zifakwe kwi-inline series network key nodes, ukuphunyezwa komgaqo-nkqubo ohambelanayo wokhuseleko lwedatha ukuchonga nokujongana ne-traffic esemthethweni / engekho mthethweni. Kwangaxeshanye, nangona kunjalo, inethiwekhi yekhompyuter iya kuvelisa ukulibaziseka kwenethiwekhi enkulu, ukulahleka kwepakethi okanye ukuphazamiseka kwenethiwekhi kwimeko yokungaphumeleli, ukugcinwa, ukuphuculwa, ukutshintshwa kwezixhobo kunye nokunye kwindawo ethembekileyo yesicelo sothungelwano lwemveliso, abasebenzisi abanakukwazi. yima.
