A smart grid is an upgraded electricity network depending on two-way digital communications between supplier and consumer that in turn give support to intelligent metering and monitoring systems. Smart grids give clear advantages and benefits to the whole society, but the dependency on computer networks and the Internet into future grids makes our society more vulnerable to malicious attacks with potentially devastating results.

ENISA has issued reports of the following areas of smart grid security:

• Smart Grid Security Certification in  Europe
• Smart Grid Security: Recommendations for Europe and Member States    
• Appropriate security measures for smart grids
• Communication network interdependencies in smart grids
