DDoS Attack Mitigation. What is DDoS Mitigation? When the botnet targets a victim's network, each bot sends requests to the target's IP address, possibly overloading the server or network and triggering a denial-of-service to regular traffic. Hence, the best measure to fight against DDoS would be to analyze incoming data, block spammy and malicious messages. The DDoS attack capabilities of Mirai which have been observed to date are well-known and can be successfully mitigated by implementing industry-standard Best Current Practices (BCPs) and by utilizing intelligent DDoS mitigation systems (IDMSes) such as Arbor SP/TMS and APS to defend the targets of these attacks. The easiest way to identify a DDoS attack is when you notice that a site or a network is unusually slow or even unavailable. Your Firewall is your first layer of defense and the most basic cybersecurity tool you can use. #2. Network operators should make use of DDoS mitigation mechanisms such as source-based remotely-triggered blackholes (S/RTBH), flowspec, and/or intelligent DDoS mitigation systems (IDMSes) such as Arbor TMS and APS in order to mitigate DDoS traffic sourced from Mirai-based botnets.
