Recently I attended a session with a panel of security experts who were discussing process control system security. There were quite a number of surprising revelations from this gathering including the need to ensure that your facility’s control system isn’t found by a search engine called Shodan. It may sound like the villain of some cyberpunk novels, but can be a real threat to the security of your control system. I’d never heard of Shodan, so I was more than a bit taken aback that something like this existed and was regularly being used by hackers to attack industrial control systems.

Here are the final suggestions to get the most out of a leadership role by creating an enjoyable and productive experience for you and your team. 5. Keep in touch. Peters and Waterman popularized the concept of “management by wandering around” in their 1982 book “In Search of Excellence.” Email is a great tool, but informal communication such as face-to-face, voice-to-voice, or even chat-to-chat provides much more information about how the work is progressing. Most of us are hesitant to voice our frustrations in a email that can live forever and be forwarded, but a simple, “How’s it going?” may elicit a lengthy and detailed description of any current frustrations or roadblocks that might adversely affect progress. Sometimes shooting the breeze clears the air. 6. Give them what they need. Make sure your team members have everything they need to keep moving forward, be ...
