Grid Security. 3 Reasons Concrete Beats High Tech Security

• most effective way to reduce damage:  installing physical barriers around substations and armoring transformers were the most effective means of reducing damage
• “security mitigation strategies are most effective when focused on improving physical barriers”
• “highest level of security upgrades considered by McGrath—daylight-quality lighting, removing vegetation, extensive physical barriers, advanced sensors, and a patrolling security guard—reduced the damage to less than one transformer damaged and none destroyed by amateur attackers.”

The data: modeling showed that an attack would “damage 77.3% of the model substation’s 20 transformers but destroy just 4.65% when only basic security measures”
