  In Sections 3.1 through 3.4, we examined a wide range of ethical concerns affecting the use of search engines, focusing mainly on what can be viewed as the “standard” or received ethical concerns that have come to be associated with search engines during the past three decades. One topic that arguably has been neglected, or perhaps considered only indirectly (e.g., in our earlier discussion of privacy-related issues in Sections 3.2 and 3.3), has to do with ethical concerns affecting (cyber)security. In addition to data security, which is closely related to data privacy (described earlier), issues associated with system and network security, as well as with national and international security, also now arise in light of a specific kind of search search engine that is capable of locating “things.” In this section, we briefly consider some emerging security-related challenges generated by the use of this type of search engine in the context of the Internet of Things (IoT).
