But over time the security aspects in the exchange of information and data to be ignored even become mandatory aspect to make the exchange of information and data to be safe from people who are not interested. To answer these challenges, Suricata comes as one solution to reducing crime in computer security that make it as an alarm when the computer server where data and information are under attack. One of the computer crime is a DOS attack is to make a server serving multiple clients at one time. It?s led to the use of bandwidth and computer memory quickly drained away. So when there is a client or other user who attempts to access the server can?t receive the service of the server because the server was down. Having conducted more in-depth a series of views of the descriptive analysis of pre-test and post-test can be concluded that the Suricata IDS is able to reduce DOS attack based on http.log, fast.log and stat.log that proved attacker with IP Flooding attack. From http header log the information that could be concluded is attacker uses Siege application doing attacking from IP address 192.168.1.2 to IP address server exactly 192.168.1.1. Fast log shows attacking data absolutely TCPv4 invalid checksum. Stat log can shows the network traffic completely. } }
