What if you only have one "user" who only logs in through SSH using port knocking and all of the server's other communication with the rest of the net is through encrypted binary data in UDP packets with fixed-size fields?
If I were interviewing you, your answer would be considered nonsense and would cause you to not get hired in the first place. I actually need to write such a server for a product I'm working on. All it ever does is encrypted communications with other machines.
True. True for all small and big companies' IT. But if you are a security or even just a forensics firm, then you ought to be in the other 0.1%
Juicy! [making notes to buy a laptop for the express purpose of logging into the server]
maybe I will hit one of the servers communicating with this "secure" computer and see if you remembered to bounds check all the data coming in
All fields are fixed length.
