Network security in the digital era needs more attention. IDS (Intrusion Detection System) is one of the anticipation method that can be used to protect computer server. Snort IDS only comes with terminal notification or web based, this method has a weakness which to transfer information to administrator network directly. Telegram is an open source instant messaging application. Combination between those applications, produce a perfect transformation to administrator network directly through smartphone. Contrive and testing are the best methods to build this network monitoring system. The Prevention methods is added to support this network monitoring system. Penetration testing is divided by two different types such as, DDoS and port scanning. The result of those two types penetration testing show that Snort IDS is succeeded to detect those tests. The time different between Snort detection and Bot Telegram after ten times attempt in sending messages is 77,1 seconds for Snort detection and 4,05 seconds for Bot Telegram. The time different between two types of penetration after ten times attempt is 6,1 seconds for DDoS UDP and 2 seconds for Nmap portscan.
