Ukuphepha kwe-cyber kuyinkambu ezikhathini zamuva eye yathola ukuvelela okukhulu ezindaweni zebhizinisi.
Yize kuliqiniso ukuthi le nkinga ibilokhu ibalulekile njalo ezinkampanini, izindawo ezintsha, ezinjenge-cloud computing, iRhlengware kanye ne Ukuba sengozini kweMeltdown kanye neSpecter kuphakamise ukukhathazeka emazingeni angakaze abonwe ngaphambili.
En Engxoxweni yakamuva neLuxux.com site, uGreg Kroah-Hartman, unjiniyela weLinux Kernel, ukhulume ngokuphepha kwiLinux Kernel nokuthi bazilungisa kanjani izinkinga zokuphepha esezivele.
Ukuphepha Okokuqala ku-Linux
UGreg Kroah-Hartman, ongomunye wabashayi besisindo ekuthuthukiseni i-Linux kernel, unikeze isitatimende kusayithi leLinux.com ukuthi ungabhekana kanjani futhi ulungise izinkinga zokuphepha.
He ukhulume ngokuthi bazisingatha kanjani futhi bazilungisa kanjani izindaba zokuphepha Futhi kulokho yena ngokwakhe akubona, kubonakala sengathi kwesinye isikhathi imvelaphi yayo ivela ezindaweni ezingalindelekile.
Isibonelo, uKroah-Hartman walungisa isiphazamisi esingalungile esikhathini esithile esedlule, kepha eminyakeni emithathu kamuva iRed Hat yathola ukuthi empeleni kwakuyingozi.
Lokhu kushade isitatimende esenziwe nguLinus Torvalds, lapho ethe khona amaphutha amaningi okuphepha ayizimbungulu.
Engxoxweni yevidiyo ye-Q & A neLinux Foundation, uGreg Kroah-Hartman ukhuluma ngezinkinga ngeMeltdown neSpecter nokuthi kungani iLinux Kernel, yize ithole izinambuzane ezahlukahlukene ezitholakala kuyo, ngokombono wakhe, iphephe kakhulu.
USwapnil Bhartiya unikeze iLinux Foundation ingxoxo emfushane yevidiyo noGreg Kroah-Hartman, osebenza "ibhizinisi eliwumgogodla" ngesikhathi uLinus engekho.
Umthuthukisi we-kernel ukuqinisekisile ukuthi ukuphepha kwe-Linux kuyinkinga ebaluleke kakhulu futhi lokho kubaluleke kakhulu ekusungulweni kwalokhu.
Lokhu kungenxa yokuthi "iLinux inika amandla umhlaba." Isibonelo, abantu abaningi ngokwengeziwe bagcina idatha ebucayi kuma-smartphone abo futhi abafuni abantu besithathu ukuthi bayifinyelele.
Lapho ebuzwa ukuthi imuphi ungqimba lwe-kernel olwalumhlupha kakhulu, uKroah-Hartman wabiza izimbungulu ze-Meltdown ne-Specter.
Isibopho esiningi konjiniyela
Okuhlupha abathuthukisi ukuthi kufanele balungise into abangayiboni endaweni yabo yesikweletu, okuyi-hardware.
Imvamisa usebenza ku-kernel ezungeze i- "black box CPU" nxazonke. Kepha ama-CPU azosebenzisa amaqhinga amaningi nangaphezulu ukuthuthukisa ukusebenza. La maqhinga kwesinye isikhathi angawela ezinyaweni zabathuthukisi, futhi i-kernel kuzodingeka ilungise lezi zinkinga.
Ngokuvamile, UKroah-Hartman wayeqinisekile ukuthi umgogodla uvikeleke kakhulu. Phakathi kokunye, ingqalasizinda yokuhlola esakhiwe eminyakeni edlule izosiza ukuvimbela izimbungulu ukuthi zingaveli lapho i-kernel patch ifinyelela emphakathini.
Ukuchazwa kokuthi ama-fuzzers afana ne-Google's Syzcaller athola izimbungulu eziningi ze-kernel ngenxa yokuthi abacwaningi bezokuphepha banamuhla bahlola amazinga ajulile we-kernel ukuthola izimbungulu ezingakaze zivivinywe ngaphambili.
Kulezi zinga kunamaphutha kwesinye isikhathi asevele akhona isikhathi eside. Kuze kube manje, bambalwa kuphela abantu ababuke le khodi.
Ngakho-ke uKroah-Hartman wayengeke athi "umhlaba uvutha umlilo", kodwa ngenxa yokuhlolwa okuyinkimbinkimbi, abathuthukisi manje sebenhle kakhulu ekutholeni izimbungulu ze-kernel.
Umhleli wohlelo ugcizelele ukuthi "benza izivivinyo eziningi" ukuqinisekisa ukuphepha okuphelele kwe-Linux kernel, nokuthi emzuliswaneni wokugcina wokulungiswa kwezokuphepha basebenze izinyanga ezine bodwa ngoba babanjiwe.
Kepha ngemuva kwenqubo eyinkimbinkimbi, uyavuma ukuthi "izinto zibheke phezulu impela."
Izindaba ezimnandi kochwepheshe ukuthi lokhu kukhathazeka okwandisiwe kuvula amathuba emisebenzi amasha, njengoba ochwepheshe bezokuphepha kwe-cyber bazofunwa ngokuya phambili.
