By now almost everyone has heard or read about the security leaks exposed by WikiLeaks. WikiLeaks has published hundred of thousands of classified and confidential information that was leaked from within the United States Government. This has been extremely embarrassing to the United States to say the least. Now in a turn of events, WikiLeaks has exposed confidential information on a US public company. WikiLeaks has exposed a series of cables about the US Pharmaceutical company, Pfizer. These leaks have been very embarrassing to Pfizer just as they are to the US.
This got me thinking and what I came up with is pretty chilling. If these leaks can happen to the United States Government and to Pfizer, could it happen to smaller organizations? I think the answer is clearly YES! You might be saying to yourself that WikiLeaks isn’t coming after my healthcare organization or medical practice. You may be right but lets take a look at another scenario.
What if an employee of your healthcare organization decided to steal electronic protected health information (ePHI)? Say they downloaded a report from your EMR and emailed the information to an external email account. Or say they took the information and copied it onto a USB flash drive. Would you even know that this has occurred?
And imagine that a week after your employee has accessed and stolen your patient information, you receive an email or letter from an unknown source letting you know they have your data. They include a sample of some of the patient information to ensure that your are convinced they really have your data. The amount of data they have could be 1,000 records (you pick the number – 5, 100, 10,000 records). And what if the email or letter demanded $100,000 (you pick the number – $10,000, $250,000, $1,000,000) or they would sell it or release it on a public website. As I said it is a pretty chilling scenario. But you may be saying to yourself that the scenario is far fetched and couldn’t happen to your organization. Don’t be so sure.
It is a well know fact that ePHI is very valuable. It can be used to commit various types of fraud. Some examples can be found here, here and here.
An employee could be motivated my many different factors that would push them to steal and blackmail an organization. The scenario is not that far fetched. Now let’s look at some steps that you can take to minimize the risk of this scenario.
Believe it or not, your best prevention is to implement the safeguards defined in the HIPAA Security Rule. Yep HIPAA can actually help you protect yourself against theft and blackmail.
The first step of this scenario was that an employee was stealing your data and you had no idea it occurred. Unfortunately I believe this is a reality in a lot of smaller healthcare organizations. In order to combat this from occurring you need to implement Audit Controls. Audit Controls as defined by HIPAA are:
STANDARD§ 164.312(b) Audit Controls
“Implement hardware, software, and/or procedural mechanisms that record and examine activity in information systems that contain or use electronic protected health information.”
STANDARD§ 164.308(a)(1)(ii)(D) Information System Activity Review
“Implement procedures to regularly review records of information system activity, such as audit logs, access reports, and security incident tracking reports.”
Basically this says that everytime someone accesses or attempts to access ePHI, you record who accessed it, when was it accessed and what was accessed. This will give you a full record of all attempts and accesses to your patient information. In addition the HIPAA Security Rule states that you have to periodically review the Audit records (Information System Activity Review). During the Audit Review maybe you see that a large number of ePHI is being access, or that repeated failed attempts to access ePHI are occurring. Audit Controls give you the insight that you need to know what is going on within your network and to your data.
Other safeguards that can help you is to implement both Technical Access Controls and Access Authorization
STANDARD§ 164.312(a)(1) Access Control
“the ability or the means necessary to read, write, modify, or communicate data/information or otherwise use any system resource. “
Access controls provide users with rights and/or privileges to access and perform functions using information systems, applications, programs, or files. Access controls should enable authorized users to access the minimum necessary information needed to perform job functions.
STANDARD§ 164.308(a)(4)(ii)(B) Access Authorization
“Implement policies and procedures for granting access to electronic protected health information, for example, through access to a workstation, transaction, program, process, or other mechanism.”
Both Access Control and Access Authorization will limit who has access to ePHI. It will also put in place technical controls and security to ensure that only the appropriate people can access ePHI. Maybe these safeguards would have prevented your employee from accessing and stealing your data.
Another safeguard that can help you would be employee education.
STANDARD § 164.308(a)(5) Security Awareness and Training
“Implement a security awareness and training program for all members of its workforce (including management).”
And an implementation specification under Security Awareness and Training is Log-in Monitoring
§ 164.308(a)(5)(ii)(C) Log-in Monitoring
“Procedures for monitoring log-in attempts and reporting discrepancies.”
A security awareness program is important to help employees protect ePHI but it is also very useful to let them know that all activity is being monitored and audited. Let them know that all log-ins are being tracked and that all access and attempts at access are being recorded. Sometimes a good offense is the best defense. If employees know that access is being monitored and recorded it may prevent them from attempting to access data that is inappropriate or prevent them from stealing your data.
Hopefully the scenario that I described never happens to your organization. But being hopeful doesn’t really help you. Implementing safeguards to prevent the scenario is the best thing that you can do.
