Seclab<\/span>\u00a0Xplore enables verification and documentation of the zones-and-conduits architecture defined by IEC 62443. The Purdue view, the flow matrix, and the segmentation diagnostics provide the necessary evidence to\u00a0<\/span>validate<\/span>\u00a0compliance and prioritize corrective actions.<\/span><\/span>\u00a0<\/span><\/strong><\/p>\n

\n

Zones-and-conduits segmentation verification<\/span><\/span><\/h3>\n
\n
The Purdue view automatically organizes equipment according to ISA-95 levels. It allows instant verification that segmentation meets IEC 62443 requirements and flags any communications crossing levels non-compliantly.<\/span><\/span>\u00a0<\/span><\/div>\n<\/div>\n<\/div>\n
\n

Validation of the least privilege principle<\/span><\/span><\/h3>\n
\n
The flow matrix exhaustively documents communications between zones. It ensures that only the necessary operational flows are allowed \u2013 in line with the least <\/span>privilege<\/span> principle prescribed by the standard \u2013 and highlights any unauthorized traffic.<\/span><\/span>\u00a0<\/span><\/div>\n<\/div>\n<\/div>\n
\n

Diagnostics and prioritized remediation<\/span><\/span><\/h3>\n<\/div>\n

Segmentation diagnostics\u00a0identify\u00a0gaps between the theoretical segmentation (as designed) and the observed segmentation (as actually deployed). Correction recommendations are prioritized according to impact. Vulnerability analysis (CVE) complements this approach by allowing remediation prioritization based on the target security levels of each zone.<\/span>\u00a0<\/span><\/p>\n

Comprehensive information is aligned with IEC 62443 requirements and is directly usable for audits. The solution pairs naturally with Seclab Xchange to ensure physical isolation of critical zones (SL-3 to SL-4).<\/span><\/p>\n

\n

Key takeaway<\/span><\/span><\/strong> \u2013 Seclab<\/span>\u00a0Xplore verifies IEC 62443 segmentation using the Purdue view and flow matrix,\u00a0<\/span>identifies<\/span> gaps, and produces audit-ready information. It integrates with <\/span>Seclab<\/span>\u00a0Xchange to physically isolate the most critical zones (SL-3\/SL-4).<\/span><\/p>\n<\/blockquote>\n<\/div>\n<\/div><\/div><\/div><\/div><\/div>\n","protected":false},"excerpt":{"rendered":"","protected":false},"author":4,"featured_media":0,"menu_order":0,"comment_status":"open","ping_status":"closed","template":"","format":"standard","meta":{"footnotes":""},"faq_category":[82],"class_list":["post-3126","avada_faq","type-avada_faq","status-publish","format-standard","hentry","faq_category-xplore"],"yoast_head":"\nHow to Verify OT Segmentation According to IEC 62443 With Seclab Xplore -
