Tofino Security
Tofino Security is changing the landscape of industrial security by going beyond traditional firewall options and providing tailored protection for zones of devices. Tofino Security provides practical and effective industrial network security and SCADA security products that are simple to implement and do not require plant shutdowns.
3 Ways to Use Industrial Firewalls for Defense in Depth
An important best practice for industrial security is implementing a Defense in Depth (DID) strategy. With this approach, multiple defense layers are implemented, in contrast to just one defense mechanism, such as a single firewall.
Zones and Conduits are integral to a DID strategy is Zones and Conduits (defined ISA IEC 62443 standard) to segment the network into device zones with similar security requirements and use conduits to restrict communication between zones.
