Iingcebiso zokukunceda ukuba ungatshisi
Ngaba uhlawuliswe ngokugcina umbane wenethiwekhi yomnatha? Oku kunokuba ngumsebenzi onzima, ingakumbi ukuba inethwekhi ekhuselwe yi-firewall ineendawo ezahlukeneyo zabaxumi, iinkonzo, kunye nezinye izixhobo zonxibelelwano ezineemfuno ezizodwa zonxibelelwano.
Izikhuni ze-Firewalls zinika ulawulo olusisiseko lokukhusela kwintanethi yakho kwaye luyinxalenye ebalulekileyo yesicwangciso sakho sokukhusela ukhuseleko lwenethiwekhi jikelele. Ukuba ayilawulwa kwaye iphunyezwe ngokufanelekileyo, i-firewall yomnatha inokushiya imingxuma ekhuselekileyo ekukhuselekeni kwakho, ukuvumela abacuki nabagwenxa kunye nokuphuma kwinethiwekhi yakho.
Ngoko, uqala phi na kumzamo wakho wokuhlawula eli lwanyana?
Ukuba uvele ungene ngaphakathi kwaye uqale ukulahla ngeList Control Lists, ungazibeka ngokungafaniyo umncedisi othile obalulekileyo obunomsebenzi obunokuthukuthela umphathi wakho kwaye uphume.
Intanethi yomntu wonke iyahluke. Ayikho i-panacea okanye inyango-yonke into yokudala ukucwangciswa kwe-firewall yenethiwekhi ye-hacker-proof, kodwa kukho ezinye iindlela eziphambili eziphakanyisiweyo zokulawula i-firewall yenethiwekhi yakho. Njengoko yonke inhlangano iyingqayizivele, isikhokelo esilandelayo asiyi kuba "bhetele" kuyo yonke imeko, kodwa ubuncinci iya kukunika inqaku lokuqala lokunceda ufumane i-firewall yakho phantsi kolawulo ukuze ungatshiswa.
Yenza ifom ye-Firewall Tshintsha Control Board
Ukwenza ibhodi yokulawula utshintsho lomlilo eyenziwe ngabameli abasebenzisi, abaphathi benkqubo, abaphathi kunye nabasebenzi bezokhuseleko banokukuncedisa ukuququzelela intetho phakathi kwamaqela ahlukeneyo kwaye kunokukunceda ukuphepha iingxabano, ingakumbi ukuba utshintsho olucetywayo luboniswa kwaye lulungelelaniswe nabo bonke abanokuchaphazeleka ngaphambi kokutshintshwa.
Ukuba kukho utshintsho oluvotelweyo lukunceda ekuqinisekiseni ukuba uxanduva lokuphendula ingxelo xa iimeko ezinxulumene neshintsho lomlilo oluthile lwenzeka.
Abasebenzisi be-Alert kunye ne-Admins Ngaphambi kwe-Firewall Rule Changes
Abasebenzisi, abalawuli, kunye nezonxibelelwano zeseva banokuchaphazeleka ngenguqu kwi-firewall yakho. Nokuba utshintsho olubonakala ngathi luncinci kwimithetho ye-firewall kunye nee-ACL zingaba nefuthe elikhulu ekuxhumeni. Ngenxa yoko, kukulungele ukuqaphela abasebenzisi ukuba batyekele utshintsho kwimithetho ye-firewall. Abalawuli benkqubo mabaxelelwe ukuba yiziphi iinguqu ezicetywayo kwaye xa ziya kusebenza.
Ukuba ngaba abasebenzisi okanye abalawuli banemiba ethile neenguqu ezicetywayo zokuguqulwa komlilo, kufuneka banike ixesha elaneleyo (ukuba kunokwenzeka) ukwenzela ukuba bathethe ukukhathazeka kwabo ngaphambi kokuba kwenziwe utshintsho, ngaphandle kokuba kwenzeka imeko engxamisekileyo efuna ukutshintsha kwangoko.
Umbhalo Wonke iMithetho kunye nokuSebenzisa izimvo zokuchazwa kweNjongo yeMithetho ekhethekileyo
Ukuzama ukufumanisa injongo yombuso we-firewall kunokuba nzima, ngakumbi xa umntu owabhala kuqala umgaqo uye washiya intlangano yaye ushiywe uzama ukufumanisa ukuba ngubani ochaphazelekayo ngokususwa komthetho.
Yonke imigaqo kufuneka ibhalwe ngokufanelekileyo ukuze abanye abalawuli bakwazi ukuqonda umgaqo ngamnye kwaye baqinisekise ukuba kuyadingeka okanye kufuneka kususwe. Izimvo kwiimigaqo kufuneka zichaze:
- Injongo yolawulo
- Inkonzo elawulwa ngumgaqo
- Abasebenzisi / amaseva / izixhobo ezichaphazelekayo ngumgaqo (Ngubani na?)
- Umhla umgaqo wongezwa kunye kunye nexesha elifunekayo lolawulo (okt Ulawulo lwesikhashana?)
- Igama lomlawuli we-firewall owongezelela umgaqo
Gweba ukusebenzisa kwe & # 34; nayiphi na & # 34; kwi-Firewall & # 34; Vumela & # 34; Imigaqo
Kwinqaku e-Cyberoam malunga nomgaqo wokulawula umlilo we-firewall, bayalwela ukuphepha ukusetyenziswa kwe "Naliphi" kwi "Vumela" imithetho ye-firewall, ngenxa yeendlela zokuhamba kunye neendlela zokulawula ukuhamba. Batsho ukuba ukusetyenziswa kwe "Naliphi na" kunokuba nemiphumo engavumelekanga yokuvumela yonke inkqubo ye-firewall.
& # 34; Denyani konke & # 34; Okokuqala kwaye Emva koko Yongeza ngaphandle
Uninzi lweemlilo ziqhuba inkqubo yazo ngokulandelanayo ukusuka phezulu kwimiqathango yomthetho ukuya ngasezantsi. Umyalelo wemithetho ubaluleke kakhulu. Ngokuqinisekileyo uya kufuna ukuba nomlawuli othi "Hlonipha konke" njengombuso wakho wokuqala we-firewall. Oku kubaluleke kakhulu kwimithetho kunye nokubekwa kwayo kubaluleke kakhulu. Ukubeka umyalelo wokuthi "Hlonipha bonke" kwindawo yesimo 1 kubaluleke kakhulu ukuthi "Gcina wonke umntu kunye nezinto zonke kuqala kwaye siza kugqiba ukuba ngubani na oko sifuna ukukuvumela".
Awunakufuna ukuba ne "Vumela konke" ukulawula njengolawulo lwakho lokuqala kuba oko kuya kunqoba injongo yokuba ne-firewall, njengoko ushiye wonke umntu.
Emva kokuba ulawulo lwakho lwe "Deny All All" luhlala kwindawo yesithuba # 1, ungaqala ukongeza imithetho yakho yokuvumela phantsi kwayo ukuba uvumele i-traffic ethile kunye nokuphuma kwintanethi yakho (kuthatha i-processwall yakho yeenkqubo ezivela phezulu ukuya phezulu).
Imigaqo yokuHlola rhoqo kunye nokuSusa iMigaqo engasetyenzisiweyo kwiSiseko esisisigxina
Kuzo zombini izizathu kunye nezizathu zokhuseleko, uya kufuna "ukuhlambulula ucocekile" i-firewall yakho ilawula ngokukhawuleza. Eyinkimbinkimbi ngakumbi kwaye imigaqo yakho emininzi, ukuqhuba ukusebenza kuya kuba nefuthe. Ukuba unemiyalelo eyakhelwe imisebenzi kunye neeseva ezingekho kwintlangano yakho kwakhona ungafuna ukuzisusa ukuze uncede ukunciphisa imithetho yakho yokucwangcisa ngaphezulu kwaye uncede unciphise inani elipheleleyo lezitshixo zobungozi.
Hlanganisa iMithetho ye-Firewall yokuSebenza
Umyalelo wemithetho yakho ye-firewall ingaba nempembelelo enkulu ekugqibeleni kwendlela yokuthutha. I-EWEEk inomxholo omkhulu kwiindlela ezifanelekileyo zokulungelelanisa imithetho yakho yomlilo wokuphucula isivinini sendlela. Esinye seziphakamiso zabo ziquka ukuthabatha imithwalo yemithwalo yakho ye-firewall ngokucoca ezinye izithuthi ezingafunekiyo ngaphandle kweendlela zokuhamba. Khangela i-athikili yabo ngamanye amacebiso amakhulu.
