Title: Security Aspects of VoIP
Author(s): Lucie Zburníková               

Abstract: VoIP is not used by the Army of the Czech Republic at present, but it can be applied in the future. Therefore, our scientific work is focused on the security of IP telephony. The aim of this work consists in categorizing the DoS (Denial of Service) attacks, making the total and topical list of them, proposing the form of detection and counteraction against them, and practical testing of the security of Cisco CallManager.

Keywords: VoIP, DoS, CallManager.
