Presented @ Saudi Aramco Global Reliability Forum 2013
Houston, TX, June 19-20, 2013
The only totally secure system is one that is shutoff, unplugged, and locked in a completely sealed box. Security is a balancing act of managing risk and maintaining operations. Too little security and the system may become compromised. Too much security may affect core system functionality, usability, or reliability. Finding the right level of security for a particular system may seem like a daunting task for many industrial control system vendors, integrators, and end-users.
There are many different aspects to security and there is no single countermeasure that will work in all situations. This talk will discuss some of the different aspects to security and discuss how some of the more common countermeasures may affect the overall reliability of the system.
