Department of Defense Now Blocking HTML Email

oKAMi-InfoSec writes "The Department of Defense (DoD) has taken the step of blocking HTML-based email. They are also banning the use of Outlook Web Access email clients. The DoD is making this move because HTML messages can easily be infected with spyware and executable lines of code that enable hackers to access DoD networks, according to an article in Federal Computer Week by Bob Brewin . A spokesman for the Joint Task Force for Global Network Operations (JTF-GNO) claims that this is a response to an increased network threat condition. The network threat condition has risen from Information Condition 5 to Information Condition 4 (also called Infocon 4). InfoCon 5 is normal operating conditions and Infocon 4 comes as a result of 'continuing and sophisticated threats' against DoD Networks. The change to Infocon 4 came in mid-November, after the Naval War College suffered devastating attacks that required their entire system be taken offline, but the JTF-GNO spokesman claims there is no connection."

    It still makes it through, it's just converted to plain text according to the article.

    Good! HTML email is very annoying. Most of the time it doesn't display as intended anyway. Many clients will only support a safer reduced set of html thus only parts of the page will display properly. This makes the page even harder to decipher. HTML email is really only useful for spammers and advertisers usually anyway. If something needs to be that heavily formatted, attach it as a word processor document. If you can't get a basic idea across in plain-text, then the problem probably isn't because you are missing your bold tag.

    Folks, the DOD is NOT blocking HTML mail, just converting it to plain text and disabling scripts, something ANY Exchange admin should already be doing in addition to Sender ID.

    Instead of facts, we get just another bash Microsoft thread. Figures.
