The National Institute of Standards and Technology (“NIST”) is planning on updating NIST Special Publication (SP) 800-66, Revision 1, An Introductory Resource Guide for Implementing the Health Insurance Portability and Accountability Act (HIPAA) Security Rule and has opened a call for comments. The last version of this resource guide was published in 2008. The comment period is open through June 15. Once the resulting draft of Revision 2 is completed, it will be published for public review and comment.
