Automated factory systems are increasingly turning to ethernet and IP-enabled networks for industrial device control and monitoring, but this level of connectivity comes at a cost. With cyber attacks on the rise, the need for integrated security is greater than ever before.
The need for increased communications between plant floor and main office has driven many factories to adopt ethernet-connected TCP/IP networks for their devices. These technologies also allow for improved diagnostic abilities, with remote access solutions giving technicians the ability to instantly pinpoint and troubleshoot problems on the plant floor from any location. The end result is less downtime, which translates to higher productivity.
But the increased presence of ethernet and TCP/IP in industrial networks is bringing with it a whole new set of security concerns. According to a recent article in Automation World,
Security has become a critical issue… Using [e]thernet and TCP/IP opens doors for the same sort of attacks that plague home and office users. Industrial networks are being hit by more and more assaults. It’s important for the control side to ensure they are taking responsibility in keeping their control networks secure and protected… As these attacks rise, more companies are realizing that these networks are no longer isolated and therefore unlikely to have security breaches. There hasn’t been a need for security technologies that protect industrial assets, so getting financial managers to allocate funds can be difficult. But many proponents say that spending on network security is just as important as buying sprinkler systems that can protect against fires.
