In this Episode of Packet Forensics Files, Endace's Michael Morris talks to Lionel Jacobs, Senior Partner Engineer, ICS and SCADA security expert, at Palo Alto Networks. Lionel draws on his more than 25 years of experience in OT and almost a decade at Palo Alto Networks in discussing some of the challenges of securing OT, IoT and critical infrastructure from cyber-attack.
Lionel talks about the challenge of detecting attacks in OT environments, how to spot unusual activity, and the importance of having a reference baseline to compare against. He highlights the importance of packet data in providing insight into what is happening on OT networks.
Lionel also stresses the importance of close collaboration between OT security teams and the operators of OT networks. It’s crucial to ensure that the safe and effective operation of critical infrastructure isn’t adversely impacted by security teams that don’t understand the operational processes and procedures that are designed to ensure the safety of the plant and the people that work there.
Lastly, Lionel reiterates the importance of gathering reliable evidence, and enabling security analysts to quickly get to the evidence that’s pertinent to their investigation. It’s not just about collecting data, but about making sure that data is relevant and easy to access.
