IDS Implementation and Security Analysis on the Public Cloud Network using RouterOS and Alert Notification with Instant Messaging

Cyberattacks have a significant impact on network performance in the public cloud. Sysadmin must be prepared to handle any attacks on the server urgently needed to prevent attacks that may interfere with the public cloud network's performance. A system is required to detect and provide early warning against any cyberattacks. This detection method is called Intrusion Detection System (IDS). This research has succeeded in improving ids network security by adding notification alerts with instant messaging capable of detecting IcmpFlooding, PortScanning, and HttpFlooding attacks. Response time of notification alert delivery in 10x the experiment of each attack obtained an average result of 21.5 seconds for IcmpFlooding, 26 seconds for PortScanning, and 29.8 seconds HTTP flooding, this response following ISO standard 27001:2013 point A.13.1.1 NetworkControls, where IDS and alert notification detect and provide valid and realtime warnings. This is expected to help sysadmin perform the next action handling against threats on the public cloud network.
