Department of Defense Now Blocking HTML Email 262
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."

They do. "A Navy user said that any HTML messages sent to his account are automatically converted to plain text." But if you've used tables or such the layout will probably be trashed, so better to reformat as plain text to begin with.
Using something like Lynx to filter HTML into plain text would give pretty good results, it does tables fairly well.

If you are DOD and you want to get Commercial Off the Shelf (COTS) products to resolve your problems without hiring the massively expensive solutions of 1 off stuff built to design, you must be able to accept attachments such as .zip and html mail. Sorry but the commercial guys cannot even tell you what they are doing anymore without this stuff. DOD costs just got higher!
I worked one DOD site where we had to email files of code. The volume of the attachments was beyond the Email limits so we had to zip the files. The filters blocked .zip. So we renamed the files .aaa or something like that. Then the filters didn't catch the files. That way we could get the emails. We had to break our own security just to do our job. This stuff is a real problem.
The US DOD needs to can Microsoft. If they were to run Linux or Apple systems and then to sandbox all emails and web browser stuff under the OS a lot could be done and things would be much more secure. The basic problem is a Microsoft logical design construct. Microsoft thought that they should own your computer and you should rent it from them. Under these conditions they wanted "their" computers to be remotely controlled by various means. The means they designed into their constructs also leave sucking security holes which hackers and other malware designers just walk right through.
There is a real reason most DOD people stick like glue to Microsoft. For Network security people in the DOD they are as worried that some subordinate might actually control his machine as they are of having foreign control. (Foreign to their system) As such they must keep central control. This is the Microsoft construct at a second level. The DOD system I worked on had an entire base having one root password that didn't change folks because of this demand. Linux etc doesn't conform to this as naturally as MS systems. Another level of this sticking like glue to MS systems comes from the fact that most of the people who program (contractors etc) for the Government like to keep their jobs. MS systems do not support legacy software well. As such they are continually "re-inventing the wheel" so to speak and it makes for lots of jobs that last a lifetime. It holds the DOD hostage to continually hiring the same contractor because his software is proprietary and cannot be easily "reverse engineered" without risk of software copyright violations. In the end this synergy of profits and control leaves the US DOD bleeding money, never able to do its job as effectively and wedded to MS systems.
If the taxpayers get involved they will ban such OS like Microsoft because this is completely contrary to the interest of the taxpayers. It however; requires the US DOD to recognize that its only true security lies in the loyalty of its people. In doing so it will have to retract from foreign (non-USA) suppliers and contractors. It will have to seriously look into who it is hiring and it will have to weed out those it has on payroll who are being more selfish than loyal. Let me assure you that if this situation is dealt with properly it will be a top to bottom 10 on the Richter Scale earthquake in US Government operations.
