IoT Security Landscape & Analysis

Technology allows society to accelerate exponentially. People are connecting Things to the Internet but the benefits arenít realized without tradeoffs. Companies are embracing IoT to enhance their business plans. Due to many difficult challenges, some IoT Security Alliances have begun to form. At the federal government level, FTC, FCC, DHS and NIST have become involved. Finally, security companies are now proposing IoT security architectures to complement Enterprise solutions. We will review and discuss all these topics.
