Arp Spoofing sald\u0131r\u0131s\u0131, genellikle bir sald\u0131rgan\u0131n a\u011fdaki bir cihaz\u0131n yerine ge\u00e7mesini gerektirir. Sald\u0131rgan, a\u011fdaki cihazlar\u0131 yan\u0131lt\u0131c\u0131 ARP yan\u0131tlar\u0131 g\u00f6ndererek, hedef cihazlar\u0131n ARP tablolar\u0131n\u0131 de\u011fi\u015ftirir. Bu \u015fekilde, sald\u0131rgan hedef cihazlar\u0131n a\u011f trafi\u011fini kontrol edebilirken hem verileri \u00e7alabilir hem de verileri g\u00f6zetleyebilir.<\/p>\n

Bu sald\u0131r\u0131 t\u00fcr\u00fc genellikle a\u011fdaki cihazlar aras\u0131ndaki g\u00fcven ili\u015fkisini bozar. Sald\u0131rgan, hedef cihazlara g\u00fcvenilir bir kaynak gibi g\u00f6r\u00fcnerek, verilerinizi \u00e7almak veya a\u011f trafi\u011finizi manip\u00fcle etmek i\u00e7in f\u0131rsat yarat\u0131r.<\/p>\n
