Practical Internet of Things Security - Second Edition

System design updates

When security flaws are discovered in IoT systems and devices, it is important to hold retrospectives focused on determining whether there are design or configuration changes that must be made to the systems and networks, or whether the devices should be allowed to operate on them at all.

At least quarterly, review the flaws discovered during the preceding three months, and focus on identifying any changes to baselines and architectures that are required. In many cases, a severe vulnerability in a particular device can be mitigated by a simple configuration change to the network.
