Mac İncelenmesi (Mac Forensic)
Mac İncelenmesi (Mac Forensic)
Popüler olan Windows’un incelenemesi için ülkemizde belli başlı bir çok yazılım bulunmakta iken Mac ile alakalı çok fazla seçenek olmadığı gibi dosya sisteminin farklı olmasından kaynaklanan zorluklar bulunduğu aşikardır. Bu bölümde Mac Os X işletim sisteminin Adli Bilişim yönüyle incelenmesi yani sanal makinada açılmış sistemde komut kodlarını Terminal(Komut konsolu)’e yazmanız halinde karşınıza açıklamaları veren ve incelemeyi hayli kolaylaştıracak bilgiler çıkacaktır. Aşağıda örnek olarak 8 Temmuza ( Jul 8 ) ait sorgulamalar yapılmıştır. Tarihi Jan,May,Dec şeklinde kısaltarak değiştirebilirsiniz.

OLAY İNCELEMESİ
Mac OS X sisteminde son aktiviteler nasıl hızlı bir şekilde tespit edilebilir? Bu konuda bash komutları ile sistem logları analiz edilebilir.
