The current rapid development of technology make network security becomes very important. Increasing number of devices connected to a network makes a lot of security gaps in the network. Administrator plays an important role in protecting the security issues on a network. The problem comes when the administrator can not always be in front of the computer to monitor the network due to illness, fatigue or are there other matters while at the same time need information fast when there is interference on the network. This problem can be solved by adding a system for the detection of traffic data or called by IDS. IDS will be linked to the SMS gateway so that the administrator can receive notification disruption on the network. In this study, researchers conducted the analysis and testing of the problems that arise so that it will produce a system that is able to detect attacks or disruptions on networks quickly and can alert the network administrator so the administrator can take precaution against disturbances more quickly. Attacks can be detected from the pattern of attacks are on the IDS rule that an intruder trying to break will be detected and the system will send SMS to the administrator.
