Abstract

Classic firewalls have long been unable to cope with modern threats that ordinary Internet users are exposed to. This thesis discusses their successors - the next-generation firewalls. The first part of the thesis describes modern threats and attacks. We described in detail the DoS and APT attacks, which are among the most frequent and which may cause most damage to the system under attack. Then we explained the theoretical basics of firewalls and described the functionalities of next generation firewalls. In the following chapter we performed various tests on three models of next-generation firewalls analyzing and presenting the test results. The aim of the thesis was to determine whether the next-generation firewalls are appropriate to replace conventional firewalls and so to contribute to the adequate protection of Internet users.
