I work as an IT consultant / implementer.
I tend to work in Big Corporations doing infrastructural software projects. This includes introducing new procedures of how IT staff is going to administer their servers in the future (e.g.: how to use SSH in the future) both by technical as well as organisational means.
This also means that the IT staff and I are not often on good terms which in turn again means I don't get cut any slack wrt. accessing the internet or getting software installed on my assigned corporate workstation. I can't download any files bigger than a certain threshold, can't download files ending in
USB is disabled on the workstations and they don't have an optical drive or a floppy drive.
Yes, IT is on lockdown.
When I have to use un-approved software (for example: wireshark for network debugging, vim for efficient file-editing) I usually upload the data I need to a private or corporate cloud instance, download it back onto my laptop via mobile phone network, do my work and transfer it back the same way.
