Security boundaries

Where do trust or privileges change, which flows cross those boundaries, and what controls are evidenced?

This view focuses on whether the supplied material evidences trust or privilege changes around the documented help and keyboard behavior. The material supports Java/Swing-oriented form artifacts and documented function-key help behavior, but it does not identify authentication, authorization, user roles, privilege checks, session boundaries, or a runtime security boundary.E0004E0005E0006

The F1 and Control-F behavior is documented in an embedded Informix-4GL example, while the supplied Java form classes do not show corresponding event-handler logic. It should therefore be read as intended or historical behavior, not verified runtime behavior.E0004E0006

No crossing relationship is asserted because the evidence does not establish that a keyboard event crosses a security boundary or changes trust or privilege. Missing security documentation does not establish either a vulnerability or adequate security.E0004E0006

Elements

Operator

Kind: actor
Basis: inferred
Description: An operator is the implied user of the menu-driven customer, order, stock, and report application and its documented keyboard-help behavior. The supplied evidence does not identify user identities, roles, authentication, or privileges.E0004E0005
Evidence: E0004, E0005
Goal: Obtain field-specific help through the documented F1 or Control-F behavior.E0004E0005

Java/Swing form layer

Kind: component
Basis: reported
Description: The supplied artifacts contain Java/Swing-oriented forms using components such as labels, text boxes, field groups, screen records, and layouts. The evidence supports UI structure, but not complete executable event handling.E0004E0005E0006
Evidence: E0004, E0005, E0006

Help and keyboard behavior

Kind: component
Basis: reported
Description: Help material documents an F1 and Control-F handler for field-specific guidance. The handler appears in embedded Informix-4GL example material, and corresponding Java runtime wiring is not shown.E0004E0006
Evidence: E0004, E0006

Application boundary

Kind: boundary
Basis: inferred
Description: A logical application boundary can be inferred around the documented menu and form behavior, but the supplied material does not define it as a security boundary or state what trust or privilege changes occur at it.E0004E0005E0006
Evidence: E0004, E0005, E0006

Relationships

None are asserted. The evidence describes intended keyboard-help behavior and Java/Swing form artifacts, but does not establish a security-boundary crossing, a trust change, a privilege change, or a control applied to such a crossing.E0004E0005E0006

Gaps

• No authentication mechanism, authorization rule, role model, privilege assignment, session boundary, or identity propagation is evidenced.E0004E0005E0006
• The documented F1 and Control-F behavior is not runtime-confirmed in the supplied Java classes; the corresponding event-handler implementation is absent.E0004E0006
• No evidence identifies whether keyboard help is available before or after authentication, whether it exposes protected information, or whether help access is restricted by role.E0004E0005
• No control can be verified for the implied operator-to-application interaction. Any keyboard-input validation, focus control, event filtering, or authorization check remains unknown.E0005E0006
• Database connectivity, SQL execution, transaction wiring, and broader runtime integration are unresolved, so no downstream trust or privilege boundary can be modeled.E0004E0006
• The supplied source analysis reports incomplete coverage and unavailable framework or implementation details, limiting conclusions about runtime behavior.E0004E0006E0007

Recovery limitations

• No supported relationships reconstructed.
• Some identified concepts have no supported connection.
• The view includes explicitly marked inference.
