Public safety practitioners utilizing the forthcoming Nationwide Public Safety Broadband Network (NPSBN) will have smartphones, tablets, and wearables at their disposal. Although these devices should enable first responders to complete their missions, any influx of new technologies will introduce new security vulnerabilities. This document analyzes the needs of public safety mobile devices and wearables from a cybersecurity perspective, specifically for the fire service, emergency medical service (EMS), and law enforcement. To accomplish this goal, cybersecurity use cases were analyzed, previously known attacks against related systems were reviewed, and a threat model was created. The overarching goal of this work is to identify security objectives for these devices, enabling jurisdictions to more easily select and purchase secure devices and industry to design and build more secure public safety devices. Why buy an eBook when you can access data on a website for free? HYPERLINKS First you gotta find it and make sure it’s the latest version, not always easy. It’s much more cost-effective to just order the latest version from Amazon.com Anyone that has worked with NIST documents knows how difficult it is to search to find that one bit of critical information. You could go to a government web site and click thru pages endlessly. Not only is it time consuming, but it is exhausting. This book is long, so printing that out on a network printer is out of the question. ePublishing changes all that. Yes, the book is available as a PDF file, but how easy is it to navigate a large PDF document on a mobile device? Do you really want to search a PDF document manually? Load this copy onto your Kindle, PC, iPad, Android Tablet, Nook, or iPhone (download the FREE kindle App from the APP Store) and you have an easily searchable copy. We recommend the Kindle Paperwhite. It’s inexpensive, has long battery life (weeks) and can hold a lot of documents. Most devices will allow you to easily navigate this ePub version to any Chapter. Note that there is a distinction between a Table of Contents and “Page Navigation”. Page Navigation refers to a different sort of Table of Contents. Not one appearing as a page in the book, but one that shows up on the device itself when the reader accesses the navigation feature. Readers can click on a navigation link to jump to a Chapter or Subchapter. Once there, most devices allow you to “pinch and zoom” in or out to easily read the text. (Unfortunately, downloading the free sample file at Amazon.com does not include this feature. You have to buy a copy to get that functionality, but as inexpensive as this is, it’s worth it.) Kindle allows you to do word search and Page Flip (temporary place holder takes you back when you want to go back and check something). https://usgovpub.com This book includes original commentary which is copyright material. 4th Watch Publishing Co. is not affiliated with the National Institute of Standards and Technology.
