Which Device Concern Is It?

About this interactive

IT departments usually manage desktops and laptops well. IoT devices and mobile devices are the ones that get overlooked, and the lesson names three concerns with them. Shadow IT: people can buy equipment easily, and they connect it without IT's permission. The organization has to decide which devices are allowed, who may buy them, and how that buying is controlled. Patching and updates: things that were never on the network before are now on it. Many have no update channel IT can reach, or none at all, so their flaws stay open. Wireless communication: mobile devices talk over cellular, Bluetooth, Wi-Fi and near-field communication. Wireless is not a secure way to send data by itself, so the device must use secure protocols. To sort a card, ask what went wrong: who brought the device in, whether it can be kept current, or how its data travels.

What you'll learn

Identify which concern a situation with an IoT or mobile device raises: shadow IT, keeping the device patched and updated, or the security of its wireless communication

Key terms

Shadow IT: The use of unauthorized software, systems, or services within an organization without IT department knowledge or approval. Shadow IT creates security blind spots because unmanaged assets fall outside standard patching, monitoring, and access controls.
Patch Management: The process of acquiring, testing, and installing software updates to fix vulnerabilities and improve functionality.
Internet of Things: A network of physical devices embedded with sensors and software that connect and exchange data over the internet.
Near Field Communication: Near Field Communication is a short-range wireless technology used in contactless payment cards, access badges, and mobile authentication; in security contexts, NFC is subject to eavesdropping, relay, and replay attacks if data is not properly encrypted.
