    Scanning legal?

    I have a question about the legal aspects of scanning a network. I am having a mild debate with a friend of mine about this and I thought that scanning was illegal, he says it is not. Neither of us know for sure so we decided to bring the discussion here. Would anyone like to help us settle the debate? Thank you.

    I was under the assumption that scanning is only allowed if you have permission, either from the Network admin or the ISP, mabey both....

    The legality of scanning is dependent on the area you live in.

    So you would need to check with the local authorities and your AUP (Acceptable Use Policy) of your ISP.

    I was under the impression that scanning isnt illegal (in Australia anyway).

    But I do know of a few ISP's that wont allow any form of scanning, and have cancelled users Internet accounts for scanning.

    Some ISP's strictly prohibit scanning in their TOS agreements - when they detect a violation of that agreement, they take the actions set forth in the agreements. Before performing scans of any kind (unless on your own network), it would be a good idea to read over the agreement you have with your ISP to determine their views on scanning.

    There's a link to help clear things up a bit. The last I heard...strictly scanning ports is not illegal...
    But if one invades a server/system in order to gain information that is not gleaned by the port scan by itself, is illegal. Forinstance, one can easily obtain the aforementioned server/system's software/version/etc through a simple scan. Any INVASION into that system/server based on the gleaned information is illegal.
    Basically, it's all about intent.

    I beg to differ. I use a local Sydney ISP and the fascist bastards disconnect me and send me a nasty email every time I run a port scan.
