When the internet "was new"....
... as far as the company I worked for was concerned anyway, I ended up unofficially-officially running the sites web proxy.
Chatting with the boss from another unit, he was interested in the setup, logging, infrastructure etc.
Rather than explain, I invited him into my office to show him.
Whilst showing him the format of the access log, I told him that whilst I didn't actively monitor them, invariably if I was tweaking/debugging, something dodgy would soon pop up.
[ I'd ignore it. Not my problem. If corporate got wind of it, and wanted to cross-reference my proxy logs with the national proxy logs, so be it, but if not, (and they never did - the whole threat of all accesses being monitored was a bluff), it's up to the persons manager to pick up if the employee is unproductive. ]
Right on cue, some softcore links popped up. "See? Told you!" I beamed. "Who is it?" he replied. I recognised the IP range as being his teams, and on looking up the specific IP, had to reply "err, it's you"!
Apparently an employee of his from another site was on site, using the bosses computer to view porn whilst he was away from his desk! I don't think it went any further than a "quiet word"!
