Industrial Control Systems (or ICS) are a hot topic in both the security sphere and at large. As critical infrastructure is increasingly internet connected, it is important to understand the realities of “ICS attacks” independently of their threat landscape. Fear, uncertainty, and doubt (FUD) often dominate the conversation around ICS attacks rather than the technical realities of these protocols that both make them difficult to defend and difficult to successfully exploit.Join SANS Principal Instructor, Alissa Torres, and DomainTools Senior Data Systems Engineer, Mike Thompson, to understand ICS infrastructure. This presentation will focus on Modbus and DNP3 protocols and aim to demystify what these attack protocols look like, and why they aren’t as bad as the FUD (fear, uncertainty, doubt) may lead us to believe.
