    We ran OWA with SSL, didn't mean our server didn't get owned by a hacker.
    Consider running a reverse proxy 'nix based box in front of your OWA box
    which runs on IIS.

    Aren't we talking about :

    "Are you using Exchange? Why not use OWA and secure it with SSL?"

    If so the idea is to authenticate to the Exchange Server with
    Credentials which may not be encrypted, but flow through an encrypted
    tunnel. SSL does not provide Authentication, correct, but it does
    provide a secure transport for said authentication via other means, in
    this case the OWA Authentication (via whatever method setup by the
    user).

    Maybe he means there is no Authentication to HTTPS?

    Anyone can type https:// and accept a certificate.

    All that does is make the traffic past that point illegible to an IDS,
    etc....

    I'd have to agree with Eric on this one. SSL is a proven encryption
    method.
    Billions of dollars are transefer via SSL encypted sites every year. If
    was as trivial to 'hack' as you suggest, Kevin, I don't think it would
    be in use. Perhaps you could do as Eric suggested and provide some
    factual proof.

    Your joking right.

    "SSL in and of itself provides very little security"

    That's why most of the internet uses it right?.

    Your gonna have to back up statements like yours with some serious
    factual backing otherwise your comments will be discarded as B.S coming
    form someone who doesn't know what they are talking about.

    SSL in and of itself provides very little security... Way to easy to
    hack.
    Look into a Neoteris (now Juniper) SSL VPN/Proxy. This way evil hack3r
    can not ride the SSL stream into your network and past any IDS or IPS
    systems.

    Hi List,
    We are thinking about deploying RPC over HTTP to access email from the
    Internet

    Wanted to get some information on the technology and the security
    implications of same

    Not much info from Microsoft's site

    any help would be greatly apreciated

    Thanks,
    Ronish
