This research explores the potential of the Sony PlayStation 4 (PS4) varian Slim, which has been converted into a web server, as an efficient platform for Open Source Security Information and Event Management (OSSEC) in detecting and responding to cyber-attacks. In the era of information technology that continues to develop, cyber-attacks are increasingly complex and threaten data and infrastructure security. Therefore, developing methods and tools that can identify threats and provide a rapid response is very important. The PS4 Slim was chosen as the research platform because of its low power consumption, potential to reduce operational costs in the long term, and ability to run OSSEC and act as a web server. In scenario testing, including penetration testing with Metasploit, Nmap, and SQL injection testing using Sqlmap, this game console successfully detected attacks and provided an efficient response. This research provides insight into the potential for sustainable use of existing resources for network security monitoring in the face of increasingly sophisticated cyber attacks.
