As industrial systems have adopted Ethernet infrastructure
and become interconnected to corporate IT systems, firewalls have become
essential components for ensuring network security and increasing system robustness
and resiliency. Firewalls come in a variety of form factors with a range of
features and technologies optimized to play different roles as part of a
comprehensive security architecture.
There are a number of different types of firewalls for
industrial control systems. A layered approach may be best depending on the
situation. Some firewall examples include:
- Network-Firewall
- Client-Firewall
- IP Firewall
- Deep Packet Inspection
- Layer 2 Firewall
- Stateless
- Access Control Lists
- Stateful Packet Inspection
- MAC Filter
- Learning Mode
- Industrial Firewall
- WLAN Firewall
- Transparent Firewall
- SPI
As the Internet of Things (IoT) grows, it becomes
increasingly important to determine how to securely and flexibly connect previously
isolated networks. Yet, firewalls can also cause frustration when legitimate
access is denied.
Are firewalls part of
your work or home network? How do you feel about them?
Learn more about firewalls, including the types, how various
security mechanisms increase security, and how firewalls can be integrated into
existing networks. Sign up for a free webinar by Belden.
