        DFIR'da Gelecek Perspektifleri ve Teknolojiler<\/h2>\n

        DFIR'\u0131n gelece\u011fi muhtemelen teknolojideki geli\u015fmelerle \u015fekillenecek. Yapay Zeka (AI) ve Makine \u00d6\u011frenimi (ML), olay tespit ve m\u00fcdahale hususlar\u0131n\u0131n otomatikle\u015ftirilmesine yard\u0131mc\u0131 olabilir. Kuantum hesaplama, yeni adli yakla\u015f\u0131mlar gerektirecek \u015fekilde \u015fifreleme standartlar\u0131n\u0131 yeniden tan\u0131mlayabilir.

        DFIR ve Proxy Sunucular\u0131<\/h2>\n

        Proxy sunucular\u0131 DFIR'de \u00f6nemli bir rol oynayabilir. A\u011f trafi\u011finin g\u00fcnl\u00fcklerini tutarak olay incelemesi i\u00e7in de\u011ferli veriler sa\u011flarlar. Ayr\u0131ca k\u00f6t\u00fc ama\u00e7l\u0131 trafi\u011fi engelleyerek olaylar\u0131n kontrol alt\u0131na al\u0131nmas\u0131na da yard\u0131mc\u0131 olabilirler. Bu nedenle, iyi yap\u0131land\u0131r\u0131lm\u0131\u015f bir proxy sunucusu, DFIR stratejisinde de\u011ferli bir varl\u0131k olabilir.<\/p>\n
