24 Security Security issues are a threat to the entire IT space Stuxnet shows us that all systems can be vulnerable Smart Grid is both “wired” and wireless Biggest security issue remains at the staff/human interface level. Active system monitoring and critical system redundancy Design security and privacy into the system from the start – and TEST IT!
