Recently we had an interesting thing which happened at work. My colleague was playing some Flash games at work and after some time someone from organization remarked about that and asked to oversee him. The situation is curious, because we are the IT department and while there are more IT specialists in our organization, I was under impression that there is no observation of employees. While it in itself is a trivial matter as we just laughed and dismissed that, I'm still curious how someone can find out activity on computer?
I had tried:
Now, I have administration privileges on my computer. I had removed all sharing and team viewing options in Windows 10 just in case, though most were off either way. I had checked ESET antivirus and could not find anything unusual there either. I had checked the installed programs menu and could not find anything unusual either, all the bare basics and I could say roughly what each software is responsible for. It doesn't seem anything to be installed on my end either. I have only suspicion that my activity could be potentially observed in internal network and through data packets someone could observe that someone is roughly doing.
How my activity on computer could be observed in my case? Is there anything that could be done in order to protect my privacy?
