Cox Technician gaining access to side house box without authorization

From my surveillance camera, yesterday 5/7/20 around 3:30pm a Cox technician came to my house while I was at work and started to fiddle with the box that is mounted to the side of my house (below my breaker box). I did NOT call for service and did not authorize for him to gain access to my property. I called Cox in the evening and was told that there’s a work order in my area to place a TAP. However, the TAP is located in the common area and NOT at the side of my house. This is very concerning.

on a side note, it is possible for someone to install some type of skimmer box that can compromise my internet security at the point of signal entry to/fro my home?
