Ukuqamba kabusha ilabhulali ye-crypto ngeke kulungise iklayenti elidala
Isixhumanisi esingokomfanekiso sishintsha ukuthi iyiphi ifayela evulwa isilayishi, hhayi isikhombimsebenzisi ibhinari eyakhelwe kuso. Hlola uhlobo lokwehluleka ngaphambi kokuthinta noma iyiphi ilabhulali.
Dlula ngephutha lesilayishi ngokulandelana: iyiphi ifayela engekho, iyiphi i-architecture esetshenziswa ibhinari, iwuphi uphawu ebeluyifuna, nokuthi ukwehluleka kwenzeke ngaphambi noma ngemva kokuqala kwenqubo. Lezi yizinkinga ezine ezihlukene, futhi isixhumanisi esingokomfanekiso sixazulula eyokuqala kuphela. Ukuzenza ngokulandelana kuvimbela umphumela ovamile lapho iklayenti liqala khona bese lihluleka ku-handshake yokuqala. Uhlu lokuhlola luphetha ngokuqinisekisa ngomsunguli wangempela hhayi ngokuhlola ngesandla.
Qopha indlela yefayela elisebenzayo, i-architecture yalo kanye nephutha lokuqala ngokwezwi nezwi ngaphambi kokushintsha noma yini.
Ukwehluleka okune okuhlukene ngemva kwephutha elilodwa
Into ehlanganyelwe engekho iyinkinga yokuthola ifayela: isilayishi safuna igama futhi asitholanga lutho. Uphawu olungekho iyinkinga yesikhombimsebenzisi: ifayela likhona futhi alikukhiphi lokho ibhinari ekhomba kukho. Ukungafani kwenguqulo yophawu kuyisigaba esifanayo ngemininingwane ethe xaxa. I-algorithm engasekelwe ebikwa ngemva kokuqala iwushintsho lokuziphatha ngaphakathi kwelabhulali eyalayishwa ngempumelelo. Ngakunye kudinga impendulo ehlukile, futhi okokuqala kuphela okuyindaba yegama.
ldd kubhinari kanye readelf -d nesigaba saso esiguqukayo kukhombisa lokho elikufunayo, futhi lokho ngokuvamile kwanele ukuhlukanisa inkinga yefayela enkingeni yesikhombimsebenzisi.
Yini OpenSSL 3 eyifunayo ngempela
Umhlahlandlela wokufuduka ku-OpenSSL 3 ucacile ngalokhu: izinhlelo ezakhelwe izinguqulo zangaphambilini zidinga okungenani ukuhlanganiswa kabusha, futhi ukuhambisana kwekhodi yomthombo akuqinisekisiwe. Izikhombimsebenzisi zashintsha, futhi ezinye zahliswa noma zasuswa. Igama lesibonelo lefayela alikwazi ukwenza ukuhlanganiswa kabusha futhi alikwazi ukufundisa ibhinari endala isikhombimsebenzisi esisha. Ukuxhumanisa ilabhulali entsha ngaphansi kwegama elibonakala lidala kukhiqiza uhlelo olungase luqale bese luhluleka endaweni engabonakali kakhulu.
Lokho kubi kunokwehluleka okumsulwa. Iphutha lesilayishi libiza inkinga ngokushesha, kanti ukwehluleka sekwephuzile ngaphakathi komsebenzi kubonakala njengenkinga yenethiwekhi noma yobufakazi futhi kuqondisa uphenyo endleleni engalungile.
Kungani ilabhulali yokusabalalisa iyindawo engalungile
Ukushintsha ilabhulali yokusabalalisa ukuze kwenelise iklayenti elilodwa kushintsha indawo yonke yohlelo ngalunye emshinini, kuhlanganise izibuyekezo zokuphepha nakho konke okuncike esikhombimsebenzisini esikhona. Ukukopisha ilabhulali endala eduze kwebhinari kuncane, futhi kusadala ukuncika okufanele umuntu akunakekele futhi akulungise. Akukho kokubili okuyindlela evunyelwe yokuhambisana, ngisho nalapho kubonakala kusebenza ngosuku lokusetshenziswa. Igama lesibonelo lomhlaba wonke elishiywa ngemva kokuhlola libi kakhulu, ngoba akekho okhumbulayo ukuthi likhona ngani.
Sebenzisa iklayenti elisekelwe nomhlinzeki kanye nesethi yokuncika yenguqulo yangempela ye-OS, i-architecture kanye nesango. Ifomethi yephakethe eyasebenza kumuntu oyedwa ayiqinisekisi indlela yamanje efanele, futhi iresiphi egciniwe iwubufakazi ngokwedlule.
Qinisekisa umsunguli, hhayi ukuqalisa
Ngemva kokushintshwa okusekelwe, hlola ukuthi umsunguli ojwayelekile uxazulula ini: ldd kufayela elisebenzayo elifakiwe, izinguqulo zelabhulali azishoyo, kanye nendawo yonke edluliswa yisevisi. Bese ugijima ukuqinisekisa okuhlosiwe kanye nomsebenzi owodwa wangempela. Ukubiza ngesandla ngendawo yonke eshintshiwe kufakazela kuphela ukuthi i-shell yakho ingayiqalisa. Umqalisi, okufakiwe kudeskithophu noma iyunithi yesevisi yikho abasebenzisi abakugijimayo ngempela.
Uma kungekho kwakhiwo okusekelwe, buza umnikazi we-VPN ngenye indlela noma indlela yokufuduka. Ukushintshela buthule kwenye iphrothokholi, noma ukucabanga ukuthi iklayenti elinegama lomhlinzeki elijwayelekile liyanelisa isango, kuhambisa ukwehluleka esikhundleni sokukulungisa.
Lapho ilungiselelo lokuhambisana lesikhashana lingenakugwenywa, kubhale phansi, kukhawulele kuleyo bhinari, futhi ukususe lapho kwakhiwo okusekelwe kufika.
