Editor's Note: Could the Hollywood hack happen to your organization?
Cyber attacks like the recent hack of Hollywood Presbyterian Medical Center are on the rise.
The event had all the hallmarks of a Hollywood blockbuster, but this month's assault by a hacker on Hollywood Presbyterian Medical Center (HPMC) was frighteningly real. The malware attack locked access to certain computer systems and prevented the medical center from sharing communications electronically, according to a statement by Allen Stefanek, President & CEO. The medical center paid the requested ransom40 Bitcoins, equal to approximately $17,000and restored its electronic medical record (EMR) system. There is no evidence at this time that any patient or employee information was subject to unauthorized access, Stefanek said in his statement.
The HPMC hack is only the latest cyber attack to plague the industry. In this guest blog post, Salim Hafid, product marketing manager for Bitglass, suggests ways organizations can safeguard themselves against these damaging events.
Data breaches in 2015 resulted in a massive 113 million leaked records nationwide, up from 12 million in 2014, according to Bitglass’ Healthcare Breach Report. This means that one in three Americans’ personal information was leaked as a result of cyber attacks. The increase suggests that hackers are increasingly targeting medical records, which contain a trove of valuable information including addresses, Social Security numbers, and patients’ medical history. As hackers become more sophisticated, IT must take steps to secure data both in the cloud and across all employee devices.
Given the rising threat of cyber attacks, healthcare organizations must be proactive when it comes to securing corporate data. Here are five ways IT can both protect healthcare data in the cloud and limit the risk of a large-scale breach:
1. Control access.
Cloud applications have made file-sharing and access to data easier than ever, but for all the flexibility these apps offer, there are risks to sharing files with unsecured, unmanaged devices outside the corporate network. Granular access controls are a critical piece of the security puzzle in that organizations need the ability to limit access in certain risky contexts. In the case of the Anthem breach for examplein which phished credentials were used in China, resulting in 78.8 million leaked recordsaccess controls would have limited the damage.
2. Encrypt, track, protect.
The most sensitive data in an organization is often the most valuable to hackers. Files with customer Social Security numbers, addresses, and medical claims information are the targets of large-scale breaches. To secure data, IT needs a means to identify the files that contain sensitive content and apply Data Loss Prevention (DLP) to those files. Contextual DLP solutions enable IT administrators to distinguish between devices and set policies to encrypt, apply watermarks to track data, or even wrap files with digital rights management (DRM).
3. Secure BYOD.
As demand for bring-your-own-device (BYOD) in healthcare rises, organizations need to protect data on unmanaged devices without impeding user privacy. What is critical here is control over data as it travels to the end-user’s device and data that resides on the device itself. With features like selective wipe and native mail access, organizations can encourage adoption of BYOD while still protecting data and maintaining HIPAA compliance on these unmanaged devices.
4. Quickly identify potential breaches.
As healthcare organizations are now more likely to be targeted by hackers than ever before, IT needs the ability to quickly identify suspicious traffic and be alerted to potential risks. Administrators can leverage tools like cloud access security brokers to act on that information and limit sharing using the aforementioned access control capabilities.
5. Improve authentication.
Major breaches like Anthem and Premera, coupled with the low rate of single sign-on adoption across the healthcare industry, highlight the need for a more secure means of authenticating users. With an integrated identity solution, organizations can maintain control over the key access points to their data and can easily manage user account credentials with tools like Active Directory. Industry standards like single sign-on, multi-factor authentication, and single-use passwords can also help minimize risk of breaches due to stolen credentials.
These are just a few of the many ways healthcare organizations can better secure corporate data in public cloud applications like Google Apps, Box, and Office 365. In light of the massive year-on-year increase in breaches, securing healthcare data has never been more critical. Healthcare organizations need a HIPAA-compliant, comprehensive, data-centric solution that provides complete control and visibility over protected health information (PHI), a means of securely authenticating users, and BYOD security.
