To secure industrial IoT, use segmentation instead of firewalls

Network World

The internet of things (IoT) has been top of mind for network and security professionals for the better part of the past five years. This has been particularly true for the area of industrial IoT (IIoT). Connected industrial devices are nothing new, but most IT people aren’t familiar with them because they have been managed by operational technology (OT) teams. More and more, though, business leaders want to bring OT and IT together to drive better insights from the combined data set.

The best enterprise level firewalls: Rating 10 top products

Microsegmentation – Secure Your Internal Network

CTOvision

The problem is that threat actors are able to get through the castle gates (firewalls) and once in, are able to evade the castle guards (IPS). The problem I have with these statements is that every network engineer I know segments their network more than just at the subnet level and their segmentation is not limited to just north-south traffic. Zero trust in my mind doesn’t really mean “trust no one” because then you would have no traffic on your network.

4 tools for managing firewall rules

Fight firewall sprawl with AlgoSec, Tufin, Skybox suites

Network World

New and innovative security tools seem to be emerging all the time, but the frontline defense for just about every network in operation today remains the trusty firewall. They aren’t perfect, but if configured correctly and working as intended, firewalls can do a solid job of blocking threats from entering a network, while restricting unauthorized traffic from leaving. For admins trying to configure firewall rules, the task can quickly become unmanageable.

Tempered Networks simplifies secure network connectivity and microsegmentation

Network World

The TCP/IP protocol is the foundation of the internet and pretty much every single network out there. The fundamental problem with TCP/IP is that the IP address within the protocol represents both the device location and the device identity on a network. This dual functionality of the address lacks the basic mechanisms for security and mobility of devices on a network. This is one of the reasons networks are so complicated today.
