In the institution in which I wanted to give some free desktop support to my professors, I was prohibited from installing ANY remote access apps due to their IT policy, which prohibits such apps due to the security risks.

My questions are:

1.) Is this a reasonable and common restriction in companies and institutions ?

2.) Are some remote desktop apps that are known to have exposed vulnerabilities that were easily exploited by hackers ?

3.) Does anyone have some suggestions on how I might share a remote user’s desktop while respecting IT department’s concerns over security vulnerabilities ?
