Šírek, Martin ; Gála, Libor (advisor) ; Hlaváč, Jindřich (referee)
Personal computer connected to the Internet is a phenomenon of our time. Hand in hand with the positive development of the possibilities offered by the Internet is an effort to abuse them. Computer attacks are the crudest way of such abuse. This work explains the nature of cyber attacks and structure of the attacks. The aim is to explain how cyber attackers threat end-users of the computer and what defence exists against it. It's an introduction to the problem. The work is based around the assumption that the reader is a beginner in the field of information technology and the depth and scope of interpretation are adapted to it. For deeper study it refers to the sources in the rich list of used literature. The introductory section describes the structure of attacks and the interrelations between threats, assets (endangered goods) and vulnerability. Considerable space is devoted to the usage of social engineering for cyber attacks. Thereinafter methods,software and objectives of the attackers are explained. Measures against attacks are not missing too. The final section explains connections between the attacker's tools.
