In last week’s Practical SCADA Security blog, I discussed how the new vulnerabilities discovered in DNP3 SCADA masters are carving big holes in the NERC’s concept of the Electronic Security Perimeter (ESP).

If you have been following SCADA news in the last month, you might have noticed an avalanche of reports and blogs on new security vulnerabilities in power industry equipment. So far, vulnerability disclosures for 9 products using the DNP3 protocol have been released by the ICS-CERT, with another 21 SCADA product disclosures on their way.
