Kodwa-ke, zingase futhi zibe sengozini yokuvikeleka uma amafayela evulwa emithonjeni engaziwa. Kubalulekile ukuthatha izinyathelo zokuphepha futhi ulandele izinqubo ezihamba phambili ukuze ugweme ubungozi obungaba khona kumasistimu ethu.

Esinye sezinyathelo zokuqala zokuvula ngokuphephile ifayela le-XXE ukuthi qinisekisa umsuka wefayela. Akufanele sivule amafayela emithonjeni engaziwa, njengoba angase enzelwe ukusizakala ngokuba sengozini kwethu. Ngaphezu kwalokho, kuhle ukuba gcina amasistimu ethu nezinhlelo zokusebenza kusesikhathini, njengoba izibuyekezo zivame ukuqukatha iziqephu zokuphepha ezingasivikela ezinsongweni ezaziwayo.

Uma sesiqinisekile ukuthi ifayela le-XXE livela emthonjeni onokwethenjelwa, kubalulekile sebenzisa ithuluzi lokuhlaziya ukuphepha ukuskena ifayela ukuze uthole izinsongo ezingaba khona. Lawa mathuluzi akhethekile aklanyelwe ukuthola nokususa uhlelo olungayilungele ikhompuyutha kanye nenye ikhodi enonya efihlwe kumafayela. Ngaphezu kwalokho, kufanele sebenzisa amasu nezinqubo zokufaka amakhodi ezivikelekile ⁣ lapho usebenzisana namafayela e-XXE, njengokuqinisekisa nokuhlunga okokufaka komsebenzisi ukuze kuvinjelwe ukuhlaselwa kwe-XSS (Cross-Site Scripting) nokunye ukuhlasela okuvamile.

Sengiphetha, ukuvula amafayela e-XXE emithonjeni engaziwa kungaba yingozi ekuvikelekeni kwamasistimu ethu. Kubalulekile ukuqinisekisa umsuka wefayela, ugcine izinhlelo zethu zokusebenza zisesikhathini samanje, futhi usebenzise amathuluzi okuskena okuvikeleka. Ukwengeza, ukulandela imikhuba emihle yokubhala ikhodi evikelekile lapho usebenzisana namafayela e-XXE kuzosisiza ukuba sinciphise ubungozi futhi sivikele amasistimu ethu ezinsongweni ezingaba khona.
