DOD bars use of HTML e-mail, Outlook Web Access
BY Bob Brewin Published on Dec. 22, 2006
Due to an increased network threat condition, the Defense Department is blocking all HTML-based e-mail messages and has banned the use of Outlook Web Access e-mail applications, according to a spokesman for the Joint Task Force for Global Network Operations.
An internal message available on the Internet from the Defense Security Service (DSS) states that JTF-GNO raised the network threat condition from Information Condition 5, which indicates normal operating conditions, to Infocon 4 “in the face of continuing and sophisticated threats” against Defense Department networks.
Infocon 4 usually indicates heightened vigilance in preparation for operations or exercises or increased monitoring of networks due to increased risk of attack.
The JTF-GNO mandated use of plain text e-mail because HTML messages pose a threat to DOD because HTML text can be infected with spyware and, in some cases, executable code that could enable intruders to gain access to DOD networks, the JTF-GNO spokesman said.
In an e-mail to Federal Computer Week, a Navy user said that any HTML messages sent to his account are automatically converted to plain text.
The JTF-GNO spokesman declined to say why the command raised the threat level except to say that Infocon levels are adjusted to reflect worldwide social and political events and activities. He said the current threat level does not bar the use of attachments, including Power Point slides used for briefings.
He also declined to tell FCW what other restrictions on e-mail that JTF-GNO has imposed. But a December 2006 newsletter of the Colorado National Guard said that under Infocon 4, Guard members receiving e-mails from any unknown source, including “mail received from unrecognized Department of Defense accounts,” should be viewed as potentially harmful.
The Colorado Guard newsletter also alerted personnel to be vigilant against e-mail “phishing” attempts to gain personal information.
The ban on use of Outlook Web mail will hit thousands of users at Robins Air Force Base, Ga., according to an internal message available on the Internet. The ban on the use of Outlook Web Access “will significantly impact the way we presently conduct business,” due to the fact that that Web mail is the primary means of e-mail access for 4,500 employees at the base, according to the message.
Robins has developed a work-around for these users to access Outlook directly by logging on to government computers with their common access cards, the internal message said.
JTF-GNO raised the DOD network threat level to Infocon 4 in mid-November after an attack on the networks at the Naval War College (NWC) required NWC to take its systems offline. The JTF-GNO spokesman said at the time that the increase in threat conditions had no relation to the attack against NWC.
Pings.
ping for future.
Somebody please help me out . . . what is HTML-based e-mail, exactly? Technical response ok.

What's the over/under on the point when Iggle injects his ignorant self into this thread?
It's making life difficult, to say the least.
We streamlined a lot of our correspondence by using HTML in e-mail...now it is text-only and we've gone back to including attachments instead of links.
The load on our Outlook Server has gone way up - many of the documents we attach are 2-5 Mbytes in size and go to multiple recipients.
Good question...
It goes 5 to 1 in the infocon world as well....
In Outlook, your emails can be formatted in HTML OR with Word.
HTML has some serious holes in it and unless the firewall grabs it, there can be active content within that HTML.
And those damn sigs crash your Outlook if you go to fast :)
Don't forget that one :)
I'm not betting :)
whoops!
I'd say the over/under is 47 1/2...
Well, I am not a tech geek, so someone will probably correct me, but I am in the Navy and was familiar with all of this already. In fact I am surprised that this even made the news.
Basically, "HTML email" refers to the encoding of the email text, and the ability to embed HTML links or graphics in an email message. All of our email is now text only, if we receive an email from someone with links, the links are disabled, and we only see text. Also, graphics are disabled, so if someone were to send an image embedded in an email, all we see is the file name of the original image.
As for web mail, such as Gmail, or Yahoo email accounts, they have been banned for a long time, at least at my command.
Golden Iggle...the resident "expert" on everything...who (allegedly) lives in a 3-story condo by the beach...who (supposedly) has a wife who still looks like a supermodel...no one more clueless you will ever find!
