People increasingly are substituting ordinary household tools with Internet-connected alternatives. Where once you’d find an ordinary thermostat, you might now encounter the futuristic-looking Nest. Instead of an ordinary CCTV camera that records to tape, you might have one that allows you to monitor your household from your phone.
The convenience this offers has a pretty sizable downside, as in recent years, internet of things (IoT) devices have proven to be somewhat of a security achilles heel.
Many don’t receive security updates, and have troublingly insecure default settings. This has allowed adversaries to use malware like Mirai to bundle them into giant botnets, which are potent enough to attack the underlying foundations of the Internet.
In recent years, we’ve seen a lot of attempts to fix this sorry state of affairs. Some, like Google, have attempted to address the underlying software used by these IoT devices. Others, like the LA-based Cujo, are more interested in stopping threats at the network perimeter, and have built an IoT-oriented firewall.
One of the more interesting IoT security devices I’ve stumbled across is Akita, from Tel Aviv’s HighIoT. This is essentially a consumer-oriented intrusion protection system (IPS), which focuses primarily on IoT threats.
