An example of the negative impact of the development of internet technology is attacks from irresponsible parties or often called hackers. Sanggar Tari Natya Lakshita’s Inventory System is a newly built system, so attack testing is needed because network security is important to maintain data integration in the network. The test is carried out using a DoS attack with the LOIC tool. IDS is the method used in research with the Snort tool that functions as an intruder detector. The study aims to determine the results and effects of attacks on the Inventory System and determine how the IDS framework works with the Snort tool in detecting attacks. carried  using 1 computer and 1 laptop. The results of the attack on the inventory system showed that Snort succeeded in detecting an attack sent by LOIC by displaying the attacker's IP and IP target through port 80, then the recommendations were given related to the stages of handling network security based on CSIRT guidelines at Sanggar Tari Natya Lakshita that can be implemented.

Information system is a system that has the ability to collect information from all sources and use various media to display information.  Microsoft Excel is a spreasheet application program (electronic worksheet), the function of Microsoft Excel is to perform calculation operations and can present data in table form, while the filter and sort data functions are used to sort or filter data, for example: the ascending function and descending to sort data from the largest or from the smallest, the Sort By and Sort On features, in addition to the filter function to display data with certain criteria, the filter feature function or often referred to as autofilter, which functions to display certain rows of data according to filters already applied and hides the rest of the remaining rows of data. This study aims to facilitate the search for staffing data at the Health Office of the City of Bima, the method of data collection using 2 methods, namely literature study and observation, the results of research that have been conducted are that there is no personnel information system because the process of searching and recording personnel data is still done manually.
