on which the components object of the different IoT projects work reliably, securely and with high
            availability. It shall cover at least:

            •  Authentication and authorization.

            •  Security in communications and security of all the elements deployed in the different components,
                especially the sensing layer.
            •  Monitoring and integrity of the system.


            The use of one or another technology, as noted in previous sections, will depend on different factors
            such as the need for bandwidth, the existence of a municipal corporate network, the coverage of
            operators, and costs.


            Figure 21 describes, in a more summarized form, the main connectivity alternatives and associated
            services:

            Wired connections are required for devices that require high bandwidth and/or where cellular
            technology is not available. This would be the case of cameras deployed to reinforce citizen security
            or traffic management.


            As noted in previous paragraphs, access to the municipal corporate network can be through the
            nearest lighting command or traffic light management centres that have connectivity. It will be
            necessary to analyse the type of connectivity available in order to adapt it to the integration needs
            of the device.
