What Customers Will See

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!
