L2Proxy Connect Operations and Resilience

L2Proxy Connect places industrial policy directly in an authenticated session path. Deployment therefore requires explicit availability, performance, policy, and evidence decisions appropriate to the customer's operational risk.

Operational controls

Control	Purpose
Enable / disable	Deliberately activate or suspend Connect inspection
Rule validation	Prevent activation of an invalid rule set
Controlled rule update	Preserve the previous active rules and restart the engine deliberately
Evaluation timeout	Bound how long a frame waits for a decision
Bounded queue	Limit accumulated evaluation work
Failure posture	Apply the customer-approved allow or block behavior when evaluation is unavailable
Runtime supervision	Restart the Connect evaluation service when required
Local logs	Support operating diagnosis on the appliance
Central event archive	Retain dissections and rule decisions for investigation and reporting

Production acceptance checklist

• Approved users and groups are documented.
• Session and access controls match the remote-work purpose.
• Equipment and point mappings are confirmed.
• User-specific rules match the intended identities.
• Representative read, control, invalid-value, and unauthorized-equipment cases are tested.
• Stateful timeout, replay, and same-session assumptions are tested where used.
• The customer approved timeout and failure behavior.
• Event storage and retention meet investigation requirements.
• Session-disconnect and account-containment procedures are assigned.
• Rollback and temporary-disable procedures are documented.

Evidence confirmed in the product

The implemented Connect path provides user, session, virtual access domain, and session type to the Rule Engine. The same identity context is stored with both protocol dissections and rule-match events. Current operational archive records demonstrate this context on multiple users and sessions, including events that retain the rule, verdict, and dynamic metadata together.

Primary enforcement scope

The customer-facing Connect offer focuses on:

• Record for observation and evidence;
• Accept for approved operations;
• Drop for policy violations.

Response generation, request replacement, and frame modification are not part of the primary L2Proxy Connect offer described in this catalog.

Product boundary

L2Proxy Connect does not replace process interlocks, relay protection, safety systems, equipment settings, operator authority, or customer switching procedures. It also does not claim every function associated with a general enterprise ZTNA suite. It provides a specific and powerful result: authenticated-session-aware industrial protocol inspection, policy enforcement, and evidence.
