Vulnerability discussion

Input devices attached to A/B switches that are in turn attached to ISs of different classification levels could input data to the wrong IS compromising sensitive or classified data and/or the IS involved.Output from output devices attached to A/B switches that are in turn attached to ISs of different classification levels could be picked up by an individual other than the one the data was intended, leading to a compromise of sensitive or classified data.The ISSO will ensure input and output devices including but not limited to scanners, printers, or plotters are not attached to A/B switches that span classification levels.

Check content

The reviewer will view the A/B switch to verify input and output devices including, but not limited to, scanners, printers, or plotters are not attached to an A/B switch that spans classification levels. If input and output devices are attached to an A/B switch that spans classification levels, this is a finding.

Fix text

Remove the A/B switch attached to ISs of different classification levels and an input or output peripheral.

Pro Tips

Lavender hyperlinks in small type off to the right (of CSS class id, if you view the page source) point to globally unique URIs for each document and item. Copy the link location and paste anywhere you need to talk unambiguously about these things.

You can obtain data about documents and items in other formats. Simply provide an HTTP header Accept: text/turtle or Accept: application/rdf+xml.
