Many companies have traditionally assumed any IoT solution is secure, and although they have had skilled IT departments working with digital security overall, they often have not focused on developing an implementation plan specifically for their IoT solutions.
At the same time, security experts have long pointed to the potential risk of large numbers of unsecured connected devices, with some saying there will have to be several major global attacks before security is taken seriously – once that happens everyone will realize just how important it is for any company deploying IoT to have a strategy regarding security.
As awareness increases the quality of security measures has also increased. This means that most IoT components have some level of security, but it is still up to whomever develops or designs the solution to make sure those components work well together.
In other words, there is no magic bullet – you still have to develop and implement your own strategy for security.
