Detekce narušení počítačové sítě
Continuous spreading and growing bandwidth of computer networks brings many security threats. Intrusion Detection System (IDS) is a mean to provide network security. Software IDS aplications gain only low throughput and that is why hardware accelerators are under heavy development. Probe Traffic Scanner is a hardware accelerator developed in Liberouter project with use of FPGA technology. Main core of acceleration is searching packet payload for simple suspicious strings. Regular expressions provide complex way of describing strings. This bachelor thesis adds feature of searching according to Perl Compatible Regular Expressions (PCRE) to Traffic Scanner Probe by implemented transformer. In addition design and implementation of control software allowing users to use functions provided by the Probe have been created. Conception of intrusion detection in network utilizing Traffic Scanner is outlined so as possibilities of cooperation with other security devices.
