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 Gateway, i-DPI edibeneyo yokuchonga iTrafikhi kunye neNkqubo yokuLawula, kunye nezixhobo ezininzi zokhuseleko / izixhobo zifakwe kwi-line series network key nodes, ukuphunyezwa komgaqo-nkqubo wokhuseleko wedatha ohambelanayo ukuchonga nokujongana. ngetrafikhi 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 abanako. yima.
