Identity and Access Management: Securing Networked Infrastructure for the Energy Sector

In order to protect power generation, transmission and distribution, energy companies need to be able to control physical and logical access to their resources, including buildings, equipment, information technology and industrial control systems (ICS). They must be able to authenticate the individuals and systems to which they are giving access rights with a high degree of certainty, whether they are employees, contractors, vendors, or partners. In addition, energy companies must be able to enforce access control policies (e.g. allow, deny, inquire further) consistently, uniformly and in a timely way across all of their resources.
