Abstract

Network security is an area that needs to be constantly monitored. New forms of network attacks are being discovered and can be divided into several categories. New forms of computer vulnerability can be monitored in various ways. It is important to rapidly discover ways to eliminate vulnerabilities and prevent their abuse. In the thesis, we have set ourselves the aim to conduct a review of recent network attacks and seek measures to prevent them. For this purpose, we have produced a short overview of network attacks. More specifically, we analyzed denial of service attacks and security vulnerabilities which have been discovered in recent years in the SSL / TLS protocol. To demonstrate how easy it is to implement a network attack with modern tools, we carried out an attack using the Heartbleed vulnerability and prepared instructions for eliminating the vulnerability.
