Yini Odinga Ukukwazi Ngobungozi Be-Log4j Ngo-2023?
Isingeniso: Kuyini ukuba sengozini kwe-Log4j?
Ukuba sengozini kwe-Log4j iphutha lokuvikeleka elitholwe kulabhulali yokugawulwa kwemithombo evulekile edumile, i-Log4j. Ivumela abahlaseli ukwenza ikhodi engafanele kumasistimu asebenzisa izinguqulo ezisengozini ze-Log4j, okungenzeka ziholele ekwephulweni kwedatha nezinye izinhlobo ze ukuhlaselwa kwe-cyber.
Iyini i-Log4j futhi isetshenziswa kanjani?
I-Log4j iwumtapo wolwazi wokugawula osuselwa ku-Java osetshenziswa kakhulu ngabathuthukisi ukubhala imiyalezo yokungena ezinhlelweni zokusebenza. Ivumela onjiniyela ukuthi bakhiphe izitatimende zelogi kusuka kuzinhlelo zokusebenza baye ezindaweni ezihlukahlukene, njengefayela, isizindalwazi, noma ikhonsoli. I-Log4j isetshenziswa ezinhlelweni ezahlukahlukene, kufaka phakathi amaseva ewebhu, izinhlelo zokusebenza zeselula, kanye nebhizinisi isofthiwe.
Kuyini ukuba sengozini kwe-Log4j futhi isebenza kanjani?
Ukuba sengozini kwe-Log4j, okwaziwa nangokuthi i-CVE-2017-5645, iphutha lezokuphepha elivumela abahlaseli ukuthi basebenzise ikhodi engafanele kumasistimu asebenzisa izinguqulo ezisengozini ze-Log4j. Kubangelwa ukuba sengozini kwe-deserialization kulabhulali ye-Log4j evumela abahlaseli ukuthi bathumele imilayezo yelogi eklanywe kabi kuhlelo lokusebenza, bese isuswa futhi isetshenziswe uhlelo lokusebenza. Lokhu kungavumela abahlaseli ukuthi bathole ukufinyelela kudatha ebucayi, bantshontshe imininingwane yokungena, noma balawule isistimu.
Ungavikela kanjani ekusengozini ye-Log4j?
Ukuze uvikele ubungozi be-Log4j, kubalulekile ukuqinisekisa ukuthi usebenzisa inguqulo ye-Log4j engathinteki ukuba sengozini. Ithimba le-Log4j likhiphe izinguqulo ezifakwe nezichibiyelo zelabhulali ezilungisa ukuba sengozini, futhi kuyanconywa ukuthi uthuthukele kwenye yalezi zinguqulo ngokushesha okukhulu. Ngaphezu kwalokho, kufanele futhi uqinisekise ukuthi usebenzisa ilabhulali evikelekile yokususa izinto futhi usebenzisa ukuqinisekiswa okufanele kokufakwayo ukuze uvimbele abahlaseli ekuthumeleni imilayezo yefayela lokungena eliyingozi kuhlelo lwakho lokusebenza.
Yini okufanele uyenze uma uthintwe ukuba sengozini kwe-Log4j?
Uma ukholelwa ukuthi isistimu yakho ithintwa ukuba sengozini kwe-Log4j, kubalulekile ukuthatha isinyathelo esisheshayo ukuze uvikele isistimu yakho futhi uvimbele ukulimala okwengeziwe. Lokhu kungase kuhlanganise ukuchibiyela ukuba sengozini, ukusetha kabusha amagama ayimfihlo, nokusebenzisa izinyathelo zokuphepha ezengeziwe ukuze uvikele ekuhlaselweni okuzayo. Kufanele futhi ucabange ukubika udaba ethimbeni le-Log4j nanoma yiziphi iziphathimandla ezifanele, ezifana ne- Ukuphepha kwe-Cybersecurity kanye ne-Ejensi Yezokuphepha Kwengqalasizinda (CISA) e-United States.
Isiphetho: Ukuvikela ngokumelene nokuba sengozini kwe-Log4j
Sengiphetha, ukuba sengozini kwe-Log4j kuwukushiyeka okukhulu kwezokuvikela okungavumela abahlaseli ukuthi basebenzise ikhodi engafanele kumasistimu asebenzisa izinguqulo ezisengozini zelabhulali. Kubalulekile ukuqinisekisa ukuthi usebenzisa inguqulo ebhayishiwe ye-Log4j nokusebenzisa izinyathelo ezifanele zokuphepha ukuze uvikele kulobu sengozini futhi uvimbele ukuphulwa kwedatha nezinye izinhlobo zokuhlaselwa ku-inthanethi.
