Security concerns raised by Republican critics of the U.S. Department of Health and Human Services' botched rollout of HealthCare.gov have been overstated, according to a memo released Friday by two Democratic members of Congress.
HHS officials, in a briefing to lawmakers this week, reported just 32 security incidents at HealthCare.gov since its Oct. 1 launch, and "there have been no successful security attacks," said the memo from Democratic Representatives Henry Waxman of California and Diana DeGette of Colorado.
The briefing was "reassuring," the lawmakers wrote. "The security of Healthcare.gov has not been breached, and hackers have had no access to personally identifiable information. HHS officials indicated that they were conducting 24-7 system monitoring and ongoing assessments in order to ensure and strengthen system security."
But it's concerning that HHS officials have found so few security incidents, said a spokeswoman for Representative Mike Rogers, a Michigan Republican who has questioned the site's security. Websites of comparable size to HealthCare.gov averaged more than 230 security incidents a day in the past year, said spokeswoman Kelsey Knight.
The lack of reported security incidents "is more concerning to us," she said. "That report shows that there's no system monitoring."
A cybersecurity expert has pointed out one security flaw at the site that could lead to phishing exploits, said Knight, whose boss is chairman of the House Intelligence Committee.
Eleven of the 32 security events remained under investigation as of Wednesday, Waxman and DeGette wrote in the memo.
Security investigators at HHS classified one of the remaining 21 events as an unsuccessful probe of the site and two incidents as inappropriate use of the site in violation of acceptable use policies. One of those two incidents was a denial-of-service attempt using malware called Destroy Obamacare, the memo said. Obamacare is the common name for the 2010 Affordable Care Act, the health insurance reform law that created HealthCare.gov.
Security investigators classified 15 of the incidents as unauthorized access, in which a website user gained unauthorized access to information. Those cases "were isolated in nature" and generally involved software bugs, the memo said. In one case that's been publicized, one user's personal information was shared with another user, the memo said, but "none of these events involved a significant breach of personal information."
In addition, security researchers ultimately decided two other events turned out to be "non-incidents," the memo said.
