Intelligence

Intelligence is the section which records your Sabotaging and Reconaissance activities. It keeps a record of all the enemies that were caught spying on you or trying to sabotage you, and of all the enemies you tried or succeeded to sabotage or recon. It is separated in two sections; "Intercepted Intelligence Operations" and "Intelligence Files".

{Intercepted Intelligence Operations}
These list the enemies that tried to sabotage or recon you. An example is this:
Intercepted Intelligence Operations
  

Basically, it lists the time when it happened (in minutes, hours, days or weeks ago at that time), who did it, what the type of Intelligence it was, the number of spies sent in, and the number of spies you executed (killed). You can click on the name of the enemy to go to his stats page.

{Intelligence Files}
The enemies you reconned or sabotaged are listed here, it doesn't matter whether it failed or succeeded, they are all listed here. An example of mine is:
Intelligence Files

Again, from the left to the right, the name, the number of recons/sabotages (these two are added up, not individually listed) and a link to the details are mentioned.
You can click the name of the enemy to go to his stats page, or click the "details" button for details on your operations.

Details are more detailed reports on your Sabotage or Recon actions on one specific enemy. It looks like this:

Listed here are the time, the type of attack, the result, the number of spies you sent, and a link to an even more detailed report. The link to the more detailed report speaks for itself; it basically tells you what happened on the operation.
