Internet services provide many benefits that are public, this is the cause of many people using the internet. Of the many benefits provided, there are many shortcomings in the internet network that can be exploited by hackers to do damage such as data theft and others. The attack that often occurs is a DoS (Denial of Service) attack which is carried out to flood the target with packets sent to the target continuously. Syn attack is a type of DoS (Denial Of Service) attack that implements the TCP/IP protocol by sending SYN request packets into the ports on the router with the aim of absorbing all available resources on the server so that the server becomes too busy and cannot control network traffic well. It can even result in a system crash (hang). MikroTik Router is one type of router that has a complete range of features to support network security such as a firewall. The firewall will filter the data received and track the connections made to determine whether the connection is allowed or denied
