The Defense Message System or Defense Messaging System (DMS) is a deployment of secure electronic mail and directory services in the United States Department of Defense. DMS was intended to replace the AUTODIN network, and is based on implementations of the OSI X.400 mail, X.500 directory and X.509 public key certificates, with several extensions to meet the specific needs of military messaging.
DMS is sometimes operated in conjunction with third party products, such as the Navy's DMDS (Defense Message Dissemination System), a profiling system that takes a message and forwards it, based on message criteria, to parties that are required to take action on a message. This combination has met success with the upper echelons of command, since parties do not have to wait for messaging center operators to route the messages to the proper channels for action. The Navy also uses Navy Regional Enterprise Messaging System (NREMS). NREMS uses an AMHS backend to send secure Organizational Messages via a web interface to Naval commands.
The US Army’s version of DMS is run solely on an AMHS platform both for CONUS and OCONUS operations. The Pentagon Telecommunications Center (PTC) is the hub for CONUS operations and there are several AMHS sites OCONUS for strategic messaging. In the tactical environment the Army deploys an independent Tactical Message Systems (TMS) that is also built on an AMHS platform for secure messaging capability in austere environments when communications with OCONUS AMHS sites are unavailable.
DMS has been coordinated by the Defense Information Systems Agency (DISA), and testing began in 1995. DMS has many third-party vendor products, such as DMDS, DMDS Proxy MR, CP-XP (the CommPower XML Portal), AMHS (Automated Message Handling System), MMHS, and CMS 1.0.
Famous quotes containing the words defense, message and/or system:
“He said, truly, that the reason why such greatly superior numbers quailed before him was, as one of his prisoners confessed, because they lacked a cause,—a kind of armor which he and his party never lacked. When the time came, few men were found willing to lay down their lives in defense of what they knew to be wrong; they did not like that this should be their last act in this world.”
—Henry David Thoreau (1817–1862)
“Here [in London, history] ... seemed the very fabric of things, as if the city were a single growth of stone and brick, uncounted strata of message and meaning, age upon age, generated over the centuries to the dictates of some now all-but-unreadable DNA of commerce and empire.”
—William Gibson (b. 1948)
“The individual protests against the world, but he doesn’t get beyond protest, he is just a single protester. When he wants to be more than that, he has to counter power with power, he has to oppose the system with another system.”
—Friedrich Dürrenmatt (1921–1990)
