The U.S. Citizenship and Immigration Services might be exposing its data to greater risks because of workers carrying files home for teleworking, a report says.
The U.S. Citizenship and Immigration Services agency might be putting data with personally identifiable information at a higher risk of exposure by allowing its employees to telework, according to a report issued June 13 by the Homeland Security Department’s Office of Inspector General.
The IG analyzed whether teleworking contributed to higher rates of lost files at the four USCIS service centers.
The centers together lose an average of 27,000 alien registration files each month, by in-office workers and teleworkers, the IG said. The missing files typically contain personally identifiable information such as Social Security numbers, fingerprints and photographs, the report states.
The IG found that the two service centers with the highest rates of telework participation experienced the highest rates of missing files. The Vermont service center was responsible for 39 percent of the lost files; its telework participation rate was 23 percent. The Texas service center accounted for 32 percent of the lost files, and its telework participation rate was 24 percent.
The Nebraska center accounted for 17 percent of the lost files and had a 17 percent teleworking rate, while the California center was responsible for 12 percent of the lost files and had a 7 percent telework rate, the report states.
“Greater telework participation increases the risks to personally identifiable information because teleworkers are transporting more Alien Registration Files to additional locations than if the [files] were processed at the office,” the report states.
One area of risk is from vehicle accidents while the files are being transferred, according to the report. In one such accident, numerous files were “scattered out of the car and across the highway,” the report states. In another incident, the driver was incapacitated and “unable to protect the personally identifiable information being transported in the car.”
On average, a USCIS adjudicator at a service center who teleworks four days per week will transport about 2,000 files a year between the office and the telework site, the report states.
The investigation also identified privacy risks from data contained on unsecured data storage devices and privacy weaknesses due to gaps in encryption, system auditing and monitoring.
The IG recommended that USCIS identify vulnerabilities and mitigation strategies at its service centers, issue privacy rules of conduct for teleworkers, and develop privacy requirements to address removable data devices and system weaknesses.
USCIS officials agreed with the recommendations.
