To see if your environment has been exposed to any attacks, navigate to 'Security' when you are inside of your environment.
In case of attacks (DDOS or / and WAF related), you will see a grid with the IP of the attacker, the URL attacked and the time of the attacks.
Every environment deployed on Amazon Web Services (AWS) is protected from DDOS attacks. If you are a victim of a DDOS attack, it will appear under the 'DDOS attacks' section.
Web Application Firewall (WAF) can be enabled on the last step of the environment creation tunnel (advanced settings option must be enabled). The setting is located under 'Performance' and 'Options'. Then WAF is available as a drop down item that you can select.
