-Notice the following lines near the top of the report.  These indicate that tripwire is not monitoring these, so it would be best to update the Tripwire configuration by including these missing objects. See [[Tripwire:Configure Tripwire|Configure Tripwire]].

-===== Do an interactive check =====
-<code bash>
-sudo tripwire --check --interactive
-</code>
-This will run the same tests as normal, but at the end, instead of outputting the report to the screen, it is copied into a text file and opened with the default editor.
-This report goes into quite a lot of detail about each file that changed. In fact, on my machine, the report generated was 2,275 lines long. This amount of information is extremely helpful in the event of a real security problem, but in our case, it's generally probably not too interesting for the most part.
-The important part is near the top.  After some introductory information, you should see some lines with check boxes for each of the added or modified files:
-<code>
-Rule Name: Other binaries (/usr/sbin)
-Severity Level: 66
--------------------------------------------------------------------------------
-Remove the "x" from the adjacent box to prevent updating the database
-with the new values for this object.
-Added:
-[x] "/usr/sbin/maidag"
-Modified:
-[x] "/usr/sbin"
-. . .
-</code>
-These check boxes indicate that you want to update the database to allow these changes.  You should search for every box that has an "x" in it and verify that those are changes that you made or are okay with.
-If you are not okay with a change, you can remove the "x" from the box and that file will not be updated in the database.  This will cause this file to still flag tripwire on the next run.
-After you have decided on which file changes are okay, you can save and close the file.
-At this point, it will ask for your local passphrase so that tripwire can update its database files.
