<h2>Abstract</h2>
<p>This document provides non-normative guidance on Web of
Things (WoT) security and privacy. The Web of Things is
descriptive, not prescriptive, and so is generally designed to
support the security models and mechanisms of the systems it
describes, not introduce new ones. However, a WoT system also
has its own unique assets, such as a Scripting API and Thing
Descriptions, that need to be protected and also have security
and privacy implications.</p>
<p>We define the general security requirements for a Web of
Things system using a threat model. The WoT threat model
defines the main security stakeholders, security-relevant
assets, possible attackers, attack surfaces, and finally
threats for a WoT system. Using this generic WoT threat model
for guidance, it should be possible to select a specific set of
security objectives for a concrete WoT system implementation.
We provide several examples using common scenarios based on
home, enterprise, and industrial use cases. We also provide
more general suggestions for the design and deployment of a
secure WoT system. All recommendations are linked to the
corresponding WoT threats in the generic woT threat model in
order to facilitate understanding of why they are needed.</p>
<p>It is not the intention of this document to limit the set of
security mechanisms that can be used to secure a WoT network.
In particular, while we provide examples and recommendations
based on the best available practices in the industry, this
document contains informative statements only. Specific
normative security aspects of the WoT specification are defined
in the corresponding normative WoT documents for each WoT
building block.</p>
