“Over the last few years, the smart grid has created both real concerns and dramatized fears about cybersecurity weaknesses and the risk of potential attacks…[T]here are a few guiding principles that can help in the analysis of these potential attacks and even prevent them. “Guiding principle #1: Assume that any security system can be breached, and plan ahead for breaches, in order to ensure that a successful attack is detected, localized and compartmentalized. Following this principle lowers the value and likelihood of an attack.”

The system must anticipate and counter these simple attacks…Other[s] require expert cryptologists and super computers…If the reward of a successful attack at this surface does not yield a proportionate benefit [to the needed resources], the likelihood of this attack is reduced. “Guiding principle #3: Use standard security protocols and best practices that have been applied in IT systems that have been - and continue to be - attacked…[If] known access control, authentication and encryption techniques…have been attacked (and revised when an attack was successful), it makes them generally stronger than a proprietary technique that has not been subjected to relentless attacks…If the industry follows…[these] guiding principles, smart meters can provide a more reliable, theft-resistant and attack-resistant grid than what is currently in place…”
