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 IAO 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 that 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.

Fix text

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

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.
