A/B switches must not be cascaded when connected to devices or ISs which are at different classification levels.
Overview
| Finding ID | Version | Rule ID | IA Controls | Severity |

| Description |

| When A/B switches are cascaded it is difficult to verify the currently selected connection is the correct selection. When A/B switches are used with ISs of differing classification levels this can lead to the compromise of sensitive data. When A/B switches are attached to ISs of different classification levels the ISSO or SA will ensure that A/B switches are not cascaded. |
