Today's Internet technology is not free from problems. Unfortunately, it is used by people who have no right to steal important data. The National ICT Training and Research Center (PUSTIKNAS) Ministry of Communication and Information Technology the Republic of Indonesia is one of the government agencies that often suffer experimental intrusion by outsiders. One solution is to implement a honeypot system that can be used to improve the security of the Internet network and can detect intrusion attempts or attacks. A honeypot system with a Modern Honey Network (MHN) has been developed to make deployment and management easier and to make the honeypot more secure. The honeypots used in this study are the Kippo, Glastopf, Dionaea honeypots. With testing of the honeypot system in the form of an intrusive attack, it can be concluded that the honeypot system managed to outwit the attacker by opening ports on a server that turned the port into a hoax and was cleared. In addition, the suspicious activity was recorded and the attacks detected.
