SMS is Broken and Hackers can Read Text Messages. Never use Regular Texting for ePHI.

Thursday, June 23rd, 2016

Security firm Positive Technologies has published a report (see their overview of attack on one time passwords and PDF of the SS7 security problems) that explains how attackers can easily attack the protocols underlying the mobile text messaging networks (i.e. the Signaling System 7 or “SS7” protocol).  In their report, they indicate how this makes it easy to attack the two-factor login methods and password recovery schemes where a one-time security code is sent via an insecure text message.

Devices and applications send SMS messages via the SS7 network to verify identity, and an attacker can easily intercept these and assume identity of the legitimate user.

Infographic: Texting in healthcare – a not-so-simple exchange

Monday, April 18th, 2016

Sending text messages between health care providers and patients is incredibly common but it is also generally a violation of HIPAA.  See: To Text of Not To Text.  Texting and healthcare.  This infographic covers when texting occurs and where the risk arises.

Are you encouraging insecurity via your Web site contact and intake forms?

Friday, April 15th, 2016

Many Web sites have “contact us” pages and other Web forms for receiving requests from existing or potential customers.  This includes “new patient intake” forms on the Web sites of healthcare providers.

 

The garden variety Web form suffers from several serious problems:

  • Spam – Getting unwanted form submissions from Web robots.
  • Privacy – Often, sensitive data is submitted insecurely through these forms.
  • Archival – You may need an archived record and backup of all submissions.
  • Notices – You may need to be alerted of form submissions, even if you are not online.

Proactive privacy vs. neglect of privacy

When your Web forms transmit data insecurely, store or send data insecurely, or otherwise to do not treat the data submitted with the level protection that it deserves, you are putting the users of your forms at risk.

The typical argument is that “it is up to the user of the forms to decide if they want to submit sensitive information.” In fact, many insecure forms even have disclaimers requesting people to not submit sensitive information if they have concerns … and then the forms go on to ask lots of sensitive questions.   Especially without a disclaimer, but even with one, the form is actively soliciting people to submit their information insecurely and requesting them to take risks with their private data.   This is not good.

In areas such as healthcare, where these forms are often collecting sensitive health data (protected health information – PHI), the fact that an organization solicits the submission of PHI through insecure, non-HIPAA-compliant means is far from a “best practice”.  Why?

DuoSecurity: Advanced Two-Factor Login for LuxSci’s Web Interface

Friday, December 30th, 2011

Two-Factor logins require users to

  1. Enter their username and password properly (the 1st factor)
  2. Authenticate a second way (e.g. by entering a code delivered to their mobile phones).
Use of two-factor authentication ensures that even if a user’s password is discovered, guessed, or captured, a malicious user still cannot gain access to the user’s account … at least not without also having access to the second factor.
Two-factor authentication significantly enhances the security of any system:
  • LuxSci staff use it for all administrative actions both through our web interface and at the server command line.
  • It is required for PCI compliance
  • It is good for HIPAA compliance
LuxSci has long offered a simple and effective Two-factor option for its web interface.  Now, LuxSci also supports DuoSecurity Two-Factor authentication with its web interface.  This option provides many advanced user and administration features and is very cost-effective (usually free) for small organizations.
