The Seagulls' winless run has seen them slip to 21st in the table, just a point clear of the relegation zone.
The manager told BBC Sport: "I don't need [assurances]. Nobody has said anything else to me and we haven't talked about the situation a lot. I think it is an unnecessary conversation.
"I haven't noticed or heard anything that would be different. If they put pressure on me or say something to me like 'it's not good, we have to win the next game or otherwise you can walk' then I would say straight away.
"As long as I am in this position I know that I have the backing of everyone in the club. When that day comes that they say 'thanks a lot, that's enough' then I know the backing is not there any more. Until that day comes I know nobody has to say to me that I have their backing. I know it is there."
