The great thing about using Tenable OT Security is working with the Tenable people .
This improved visibility helps customers protect critical infrastructure while meeting compliance requirements .
“ There is no silver bullet when asset scanning in an OT environment . Some of these old devices are not compatible with any proprietary protocols or even Simple Network Management Protocol ,” said Bailey . “ A flexible tool like Tenable OT Security – which allows for manual asset enrichment – is essential .”
Wärtsilä is also helping its customers save time and increase productivity .
Before integrating Tenable OT Security , the asset inventory was tedious and time-consuming , taking , on average , two technicians around seven hours per installation . Automated processes help technicians work more efficiently , with improved accuracy .
“ Automating the asset inventory process saves Wärtsilä ’ s suppliers several hours of tedious work while improving the accuracy of the inventories for customers ,” added Bailey . “ With fewer errors and more consistency in the data , Wärtsilä can standardise and normalise the data .”
Tenable OT Security can also create an asset map based on what it senses on the network . As various OT assets ‘ talk ’ to each other across the network , Tenable OT Security uses that information to gather valuable context .
“ Our vision is to use Tenable OT Security to create a digital twin – a 3D map of how devices are connected and snapshots of all configuration changes – with near real-time asset visibility ,” said Bailey . “ In the past , we ’ ve done it on an ad-hoc basis , but the data is only good for that point in time , the process is timeconsuming and we may not get all of the device contexts we need .”
In addition to providing customers with complete and accurate asset inventories , Tenable is enabling Wärtsilä to develop new services that help customers visualise their OT environment . Tenable Security Center – a vulnerability reporting engine that gathers and evaluates vulnerability data distributed across the enterprise – will enable rich reports that illustrate vulnerability trends over time , allowing Wärtsilä ’ s customers to assess risk and prioritise vulnerabilities .
“ In the future , we will install Tenable Security Center and provide a dashboard and reports to customers through a service we ’ re calling the ‘ Asset Visualisation Service ’. When customers don ’ t know what assets they have , we can provide an inventory and a vulnerability report ,” concluded Bailey . u
