Top Five Security Threats for 2006

In anticipation of the new year ahead, I’d like to look at those things
most likely to test our security patience. Let’s talk about the Top Five
things we can anticipate becoming bigger issues or more insidious threats
in the months to come.

To know the future, you must understand the past and this has never been
more the case in IT than it is today. The future will carry many things
that have foundations in the threats and exploits of the past year or
two. Without a clear understanding of those things, the threats and
vulnerabilities of the new year will seem overwhelming.

Here are my Top Five things to look for in the new year — and why you’ve
already seen foreshadowings of them and should be prepared to deal with
them.

  • Targeted Phishing Scams — It will seem like they are more
    narrowly focused but when you take a look at all the attempts, you’ll
    see that’s not true. It isn’t that they are more targeted, it’s that your
    filtering systems already have taken out the ones most likely to be spam
    and left those that are possibly related to you or your interests. Fuzzy
    logic is a nifty thing.

    The bad news is that your end users are going to be more susceptible to
    these because the scams will look like the real thing. Now is the time to
    start educating your users on methods to protect themselves.

  • Self-Contained Electronic Devices — PDA/pager/phone/email —
    it’s all in one box! Be the first on your block to carry the all-in-one
    solution to staying connected. Be the first on your block to download the
    Blackberry- or Treo-targetted virus. Be the first on your block to bring
    the company Intranet down with a piggy-backed payload designed for
    desktops. I think we’ll be seeing the first cross over infections from
    hand-held devices to desktops and corporate networks in the coming year.

  • Spam — That unwanted bulk email will become more insidious in
    getting around spam filters at both the border and application level. As
    spam filtering becomes more sophisticated, we’ll see messages that are
    less like advertisements and more like email addressed specifically to
    us. Like phishing schemes, spam will feel more personally directed.

  • Voice over IP — VoIP will continue to be the industry’s darling
    ‘innovation’. The media focus, however, has most frequently failed to
    address possible security concerns. In all the articles on the subject
    that I’ve read, only one of them comments on security implications.

    One way to really simplify the matter is to ask two questions: When was
    the last time you had an analog phone compromised and a keystroke logger
    installed? Oh, yeah. Never. When was the last time any one of your
    workstations was compromised with any form of rootkit? A lot more
    frequently than you’d like to admit to probably.

    So, let’s hook the phones up to the computer so any traffic sniffer will
    not only have access to all your data, but all your strategic and
    tactical discussions on how to build your company successfully. Warning
    bells should be going off for even the most inexperienced IT manager at
    this point.

    To be practical about this, you are effectively setting your company up
    for a single point of failure. And it’s one that is known to occur on a
    consistent, if not regular, basis, and one that can cause considerable
    damage before identified and remediated. By adding your phone lines to
    this matrix, you increase the amount of damage possible prior to
    discovery.

    I am not saying that you cannot implement VoIP securely. Setting up your
    VoIP implementation should mean taking the necessary precautions to
    secure the implementation appropriately. Securing the server that will be
    handling your phone calls, setting traffic on a protected subnet and
    other precautions specific to your environment are paramount. I’ve heard
    how some are excited to be able to push phone calls over to wireless
    access points for greater convenience. This indicates to me that they are
    really missing the key point to security.

    As with any technology, proper security implementation has to be included
    from the outset. Attempts to add security as a secondary consideration
    are going to cause difficulties in the implementation. If you come to a
    point where VoIP is no longer a discussion but a directive, it’s time to
    switch to arguing for appropriate security levels and valid descriptions
    of the threats to corporate assets.

  • The House of Gates — Microsoft will continue to experience
    setbacks in the security arena. With more than 5 billion lines of code
    to sort through, Micro$oft will have more zero-day events to deal with
    similar to the one announced in late December.

    The .WMF vulnerability and exploit was reported late in December, and
    published in Microsoft Security Advisor 912840. It has shown that
    Microsoft is not in the clear for future events of this nature. Exploits
    will continue to become more esoteric, as well as virulent in the sense
    that they will affect a wider spectrum of the Windows operating systems.

    In the case of the .WMF vulnerability, every version of Windows is
    vulnerable (even those Microsoft no longer supports security patches for)
    regardless of patch level.

    Second, it’s not just one portion of the operating system that is
    affected but multiple major portions. The Windows Fax and Image Viewer
    library (shimgvw.dll) is used to render images in Windows Explorer,
    Internet Explorer and other applications such as Lotus Notes. Anything
    that gives a view (whether thumbnail image or full view) of an image is
    at risk of processing malicious code in an image that’s been downloaded
    from the Internet, or transmitted by email or instant messenger service.

    System administrators will have to decide whether to use third-party
    patches or wait for the official patch from the House of Gates. This will
    be the case, as well, in future incidences.

    This is the future — more spam, more phishing, more really cool
    technology gone awry, and Microsoft making your life difficult, because
    you can’t live with them and you can’t live without the operating system.
