Thank you for your question.
Of course, we have security rules at several levels. First, we screen the staff that we hire. People with more specific access have “Secret” security clearance instead of a lower level of clearance. A whole host of physical security measures are in place. People working in call centres, who have access to screens showing taxpayer information, may not have their personal phones with them. We have measures in that regard.
As for access to taxpayers' data, those data are on separate servers that are not connected to the Internet. There is a mechanism by which the employees' access to the data is reviewed annually, or each time they change jobs. Managers verify the access those employees have on a regular basis.
As for the workload, in my introductory remarks, I talked about the administrative rules. When we give employees their workload, our business fraud management system checks by using algorithms in real time. The system applies several dozen rules. For example, if employees check their own tax accounts, an alert is automatically issued and the system sees it immediately. If employees work on tasks that they have not been assigned, the system will immediately send an alert to the manager, who would then be able to ask an employee what he or she was doing in the system. Screen shots are captured per minute, which allows us to see which pages employees are consulting or which changes they have made. The system was implemented in 2017 and it is very advanced. It allows us to have controls in place.
In terms of preventing data breaches, employees are unable to copy information onto CDs, DVDs or USB keys. The system does not allow it.
