Za posledních patnáct let dochází k nárůstu počtu i závažnosti datových úniků u firem nakládajících s důvěrnými daty zákazníků a dalších osob. Cílem řady zkoumání bylo posoudit dopad takovýchto incidentů na tržní hodnotu postižených firem, nicméně všechny se zabývaly úniky před rokem 2008. Cílem tohoto příspěvku je představit výzkum, v rámci kterého byla provedena analýza dopadu úniků dat na tržní hodnotu na vzorku 27 firem postižených takovýmto incidentem mezi léty 2008 a 2012.

Keywords: únik dat, tržní hodnota, analýza dopadu
