SCADA Problems Too Big To Call 'Bugs,' Says DHS

chicksdaddy writes "With the one year anniversary of Stuxnet upon us, a senior cybersecurity official at the Department of Homeland Security says the agency is reevaluating whether it makes sense to warn the public about all of the security failings of industrial control system (ICS) and SCADA software used to control the U.S.'s critical infrastructure. DHS says it is rethinking the conditions under which it will use security advisories from ICS-CERT to warn the public about security issues in ICS products. The changes could recast certain kinds of vulnerabilities as 'design issues' rather than a security holes. No surprise: independent ICS experts like Ralph Langner worry that DHS is ducking responsibility for forcing changes that will secure the software used to run the nation's critical infrastructure. 'This radically cuts the amount of vulnerabilities in the ICS space by roughly 90%, since the vast majority of security "issues" we have are not bugs, but design flaws,' Langner writes on his blog. 'So today everybody has gotten much more secure because so many vulnerabilities just disappeared.'"
