Hey Everyone,

I am looking for a pre written legal banner for my cisco routers. Basically a detourent for any unauthorized users. I was looking for something like:

Unauthorized Users Prohibited
If you are an unauthorized user please logoff now or you will be proscecuted!

I know how to apply it to the router, but I dont really know what to say and our company doesn't really have a true legal department.

Thanks in advance.

    Just state something like 'data theft is a crime and is punishment is subject to the laws of the land. If found guilty, it could result in imprisonment'

    The reason why they use banners I suppose is.. if there is an infringement, you could always say there was a warning message for the person committing it.

    I know this is closed but for future reference, General Rules of Banners:
    1- Do not include your company name of any company info
    2- Never say 'Welcome' (this is debatable, some say that a hacker being prosecuted once used this as a defense and was acquitted. This might be an urban legend, but why take chances?)
    3- Be brief, vague and inclusive in your threat to prosecute.
    We use this:
    WARNING:  Private Network
    ***Authorized Personnel Only***
