EThis paper is study regarding banking institution and DoS attack regarding government organization which occurred in 2008. We used a tool aggressive actual DoS You install the N-IDS which used Snort in networks in order to detect a DoS attack. Storages of Winpcap and a packet to detect a packet and MySQL, HSC, to analyze. We install NET Framework etc. E-Watch etc. analyzes Packet regarding a DoS attack of a hacker and TCP, UDP etc. information, Port, MAC and IP information etc. through packet analysis tools. There is a meaning you analyze data regarding the cyber DoS, DDoS attack that is dysfunction of Ubiquitous Information Society, and it generates forensics data regarding an invader and back-tracking analysis data, and to ensure safe Internet information system through this paper study.
