Implementing LWM2M in Constrained IoT Devices

March 1, 2016

Lightweight M2M (LWM2M) is a system standard in the Open Mobile Alliance (OMA). It aims to develop a fast deployable client-server specification to provide machine to machine (M2M) services. It acts as an OMA device management (OMA-DM) successor for use in M2M and provides efficient device management as well as security workflow for IoT applications using the same protocol, thus offering enhanced simplicity. It also addresses service and management needs of constrained M2M devices over a number of transports and bearers. The LWM2M specification provides APIs for device configuration, connectivity monitoring/statistics, security, firmware update, server provisioning and so on. The widely used Constrained Application Protocol (CoAP) provides in-built binding for LWM2M, thus making it particularly appealing for the Internet of Things (IoT).

How to meet the IoT security requirements of today and tomorrow

whitePaper | July 4, 2023

Governments around the world are creating Internet of Things (IoT) security legislation and regulations designed to keep users safe in an increasingly connected world. Connectivity is good and, in fact, great but bad things can happen to people with unprotected or poorly protected IoT devices. Failing to meet government regulations or guidelines may lead to the inability to sell products in a region and thus to lost revenue. However, the regulations are constantly in a state of flux. This white paper provides updated background on what governments are suggesting or requiring as well as specific details on how to implement security defenses and obtain security certifications that can satisfy current and even future government requirements

How Virtual Desktop Infrastructure (VDI) Can Help Your Business Survive the Pandemic—And Prevail in the Future

whitePaper | August 23, 2022

Growing demand for remote working solutions in light of the pandemic is bolstering the case for virtual desktop infrastructure (VDI) adoption. In this white paper, we discuss why VDI is best suited for today’s business environments, especially since remote work is poised to play a big role both now and in the “new normal” of a post-COVID-19 world. We discuss VDI’s main advantages, its shortcomings and what can be done to address them.

Empowering DSOs to secure the Smart Grid

whitePaper | February 6, 2020

As the world’s growing need for energy meets the power of the Internet of Things, the traditional energy marketplace is rapidly transforming. Millions of meters and energy assets are connected and digitized each year, providing enormous benefits to the entire ecosystem: real time tracking of energy production and consumption data, optimized load balancing systems, streamlined operations and billing systems to name a few. As connectivity expands and the landscape is digitalizing, new distributed energy resources (DERs) and stakeholders are able to integrate into and expand the grid. DERs offer non-carbon resources that improve the energy sector’s overall carbon footprint, a key benefit for everyone.
