Stands for "Acceptable Use Policy." An AUP is list of rules you must follow in order to use a website or Internet service. It is similar to a software license agreement (SLA), but is used specifically for Internet services.
Most well-known, high traffic websites include an AUP, which may also be called Terms of Service (TOS) or Terms of Use (TOU). You can often find a link to the to the website's AUP in the footer of the home page. Many web services, such as cloud applications require you to agree to an AUP in order to use the online service. ISPs often provide an AUP with each account, which states specific guidelines you must follow.
