The gateways are deployed at consequence boundaries. The biggest \u201cspeed bump\u201d in the learning curve for this tech is \u201cI see how this might work for others, but I have special needs.\u201d In this session we review unidirectional use cases, design patterns, and technologies for consequence boundaries that include unidirectional outbound, unidirectional inbound with TPM security, time-limited bi-directional, time-limited unidirectional, two-way unidirectional, and hardware enforced remote access.<br \/>\nThese tools and designs do not replace all firewalls in a defensive architecture \u2013 far from it. In this workshop we review where unidirectional technology is used and why, and what security benefits are provided in these contexts.<\/p>\n<p>Speaker: Tjeerd Zwijnenberg \u2013 Waterfall Security<\/p>\n<p><a class=\"header__button button\" href=\"https:\/\/events.fhi.nl\/it-infra-2026\/begin?ref=Website\">Register<\/a><\/p>\n<p><em>Tjeerd is the Regional (Sales) Director Europe for Waterfall Security Solutions, the global leader in Industrial (OT) Cyber Security based on Unidirectional Security Gateway technologies.<\/em><\/p>\n<p><em>Prior to this, he worked for 20 years at OSIsoft\/AVEVA and Honeywell Process Solutions at the OT side of the business.<\/em><\/p>\n<p><em>His background is Aviation Engineering in Amsterdam (BSc) and Technical Business Administration at the University of Eindhoven (MSc).<\/em><\/p>\n<p><em>He&#039;s working with largest CNI in Europe, NCSCs, Regulators, and being a member of FHI and European Energy ISAC.<\/em><\/p>\n<p><em>His goal is to make the industry more resilient against outside attacks including targeted ransomware.<\/em><\/p>\n<p><em>Compliance, business continuity, and safety of people and environment are key in here.<\/em><\/p>\n<\/div>\n\t\t\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t<\/div>\n<\/div>","protected":false},"excerpt":{"rendered":"","protected":false},"author":43,"featured_media":0,"parent":0,"menu_order":0,"comment_status":"closed","ping_status":"closed","template":"","meta":{"_acf_changed":false,"footnotes":""},"branches":[13],"events":[364],"secretariat":[],"categories":[],"themes_tax":[],"class_list":["post-87473","page","type-page","status-publish","hentry"],"acf":[],"yoast_head":"<!-- This site is optimized with the Yoast SEO plugin v28.3 -
