Security experts are saying the patchwork method of fixing the federal health insurance exchange site raises concerns, The Wall Street Journal reports.
The doubts raised by experts add to the recent slew of security questions coming from Republicans. Rep. Darrell Issa, R-Calif., chairman of the House Oversight Committee, subpoenaed the Health and Human Services Department for information on HealthCare.gov and whether it is safe from hackers.
Eleven Republicans on the Senate Finance Committee are also requesting more information about the site's security and sent a letter to HHS Secretary Kathleen Sebelius indicating their concerns.
A Sept. 27 memo signed by Centers for Medicare and Medicaid Services Administrator Marilyn Tavenner said the security of HealthCare.gov was not been tested end-to-end.
