Vulnerability discussion

Without the presences of tamper resistance seals the A/B switch or its connections can be tampered with and the tampering will go undetected. This can lead to the compromise of sensitive data or the compromise of an IS.When an A/B switch is attached to ISs of different clearance levels the IAO or SA will ensure that tamper resistant seals are attached to the A/B switch and all IS cables at their attachment points.

Check content

The reviewer will, for an A/B switch attached to devices or ISs which are at different classification levels, view the A/B switch to verify that tamper resistant seals are attached to the A/B switch and all IS cables at their attachment points.

Fix text

For an A/B switch attached to devices or ISs which are at different classification levels, attached tamper resistant seals as required by the SPAN STIG.
