I think my interpretation differs only in the role of Sensor Operations. To me, that's less of a pure Matrix action and more something you do when working through a device. So, I'd put Jump Into Rigged Device under Sensor Operations, Check Overwatch Score under Communications*, and Snoop under Encryption. But, I could see it be interpreted your way just as easily.
* I was originally thinking Encryption, but if Baby Monitor can track it without a test, then it doesn't seem to be something requiring a lot of decoding.
