Today there was unusual traffic patterns occurring on the network and servers containing sensitive information is sending traffic outside of the internal network.
Instructions:

Also write up any vulnerabilities that may be discovered during the incident and include recommendations on how to address them.
In addition to the criteria above, provide a vulnerability framework and explain how built-in security versus that of bolt-on security could help increase the security posture of the nuclear facility against attacks. Pleas cite reputable sources.
