I-Apple iqinisekisa ukuthi iSpecter neMeltdown kuthinta i-iPhone, i-iPad ne-Mac

Kulo nyaka u-2018 siwuqale ngawo izingqinamba zokuphepha kuma-processor we-Intel, AMD, ne-ARM. Njengoba wazi kahle, i-Apple isebenzisa ezimbili zalezi zinhlobo kumakhompyutha ayo: i-Intel ne-ARM. Futhi ngaphambi kokushicilelwa kwemininingwane eminingi, inkampani ithathe isinqumo sokubonakala phambili futhi qinisekisa ukuthi wonke amakhompyutha akho - ngaphandle kwe-Apple Watch - athinteka yizo zombili izingcuphe ezaziwa ngaphansi kwamagama Ukuncibilika kanye neSpecter.

Into yokuqala okufanele uyazi: wonke amaqembu abo ayathinteka - woza, njengobuningi bomncintiswano. Manje, njengoba kuchaziwe esitatimendeni, ngoDisemba 2017 sebevele bathatha izinyathelo kulolu daba nasekubuyekezweni kwezinhlelo zokusebenza ze-iOS 11.2, iMacOS 10.13.2 ne-tvOS 11.Ama-patches wokuvikela ama-2 asevele akhona ukunciphisa umthelela we-Meltdown kumakhompyutha ethu. Kodwa-ke, kwaSpecter bayaqhubeka nokusebenza futhi isibuyekezo sizokhishwa kungekudala kuzinguqulo zesiphequluli sewebhu seSafari se-macOS kanye ne-iOS.

Ukuncibilika, ngokusho kwenkampani, ukuthi kusengozini "Amandla amakhulu okuxhashazwa". Lokhu kuba sengozini kusebenza kanjena: kuvumela uhlelo ukufinyelela imemori, ngakho-ke futhi nezimfihlo zezinye izinhlelo nohlelo lokusebenza uqobo, njengoba kuchaziwe kusuka Ukuhlaselwa kweMeltdown. Ngaphezu kwalokho, sikushiya nevidiyo yokuthi lokhu kuhlasela kuzokwenziwa kanjani ngesikhathi sangempela ngokukopisha iphasiwedi:

Ngakolunye uhlangothi, ngeSpecter, izinto ziyashintsha. U-Apple uphawula ngombhalo wakhe ukuthi: "Yize kunzima kakhulu ukuxhaphaza, noma ngabe uhlelo lokusebenza olusebenza endaweni ethile kwi-Mac noma i-iOS device, bangaxhashazwa kuJavaScript esebenzisa isiphequluli sewebhu". Kungakho basebenzela ukumaka isiphequluli sewebhu seSafari kunguqulo yedeskithophu nenguqulo yeselula.

Ukukunikeza umbono, iSpecter, ngokweMeltdown Attack ithi: “ISpecter yehlukanisa ukuhlukaniswa phakathi kwezicelo ezahlukahlukene. Vumela umhlaseli bakhohlise izinhlelo ezingenazo iziphazamisi, abalandela imikhuba emihle, ukuze bavuze izimfihlo zabo.

Ngakolunye uhlangothi, uma ukwazile ukufunda eminye imininingwane kulezi zinsuku — isihloko siyisiphithiphithi ngokujwayelekile -, uzokwazi ukuthi izibuyekezo ezivela isofthiwe yiziphi izinkampani ezethula izinhlelo zazo zokusebenza (Microsoft, Google, Apple), behlisa ijubane amaqembu ngo-5-30%. I-Apple iyazi ukuthi lolu daba lubucayi kulezi zinsuku, ikakhulukazi ngemuva kwe- I-Slowgate ukuthi umlingani wami uMiguel ubhapathize ezinsukwini ezimbalwa ezedlule.

Kungakho, embhalweni, labo abavela eCupertio bebefuna ukufihla umhlane wabo futhi babike ukuthi ukusebenza kwemishini, ngemuva kokufakwa kwezibuyekezo, kucishe kungabonakali, ngokusho kwemiphumela etholakele. usebenzisa amathuluzi wokulinganisa afana neGeekBench 4, noma amathuluzi wokulinganisa wokuphequlula iwebhu njenge-Speedometer, i-JetStream ne-ARES-6.
