Isode Server Software Solutions for the Military Industry

Isode has been delivering server software product central to military messaging and directory deployments worldwide for more than 20 years.

The firm is a trusted provider of messaging infrastructure products Military Messaging and Internet Protocols, as well as gateways to connect military and non-military messaging systems.

Secure and scalable military messaging and directory solutions

Isode have a strong engineering focus with 75% of its staff dedicated to writing and / or testing code.

Partnering with only experienced systems integrators, the firm delivers successful, competitive, secure and scalable messaging and directory solutions to militaries, intelligence services, aviation authorities and governments worldwide.

Directory services for tactical and strategic systems

Directory services are a critical military component, used for tactical and strategic systems. Military directories, specified by ACP 133, are used to provide information services, support of military messaging, and as supporting infrastructure for other applications such as public key infrastructure (PKI).

The M-Vault X.500 directory server provides a unique set of security features, including strong authentication based on X.509 PKI, security policy, rule-based access control based on security labels, audit logging and password policy.

M-Vault comes with full ACP 133 support and conformance, including graphical user interface (GUI) support for data administration, and using the firm’s Sodium Sync product flexible directory synchronization with lightweight directory access protocol (LDAP) directories is provided.

Secure XMPP for military use

Isode’s M-Link (together with their Swift XMPP Client) was the first extensible messaging and presence protocol (XMPP) server to gain a listing on the Defense Information Systems Agency (DISA) Approved Products List and is used by militaries in Europe, North America and the Middle-East.

M-Link is also the server behind JChat+, which is the system delivering instant messaging, multi-user chat and structured forms services within Nato’s Afghan Mission and Federated Mission Networks.

Isode has incorporated security features that make M-Link the natural choice for XMPP in military, intelligence and government deployments. These features include support for security labels, data confidentiality using transport layer security (TLS) and support for simple authentication and security layer (SASL) authentication, Kerberos authentication and strong authentication for client / server and for server / server connections.

Along with the abundance of security features, Isode has ensured M-Link has a range of capabilities for operating over networks with low bandwidth, including support for federated multi-user chatrooms and extensible markup language (XML) stream compression. M-Link can also be configured to act as a gateway between XMPP multi-user chat rooms and internet relay chat (IRC) channels.

Formal military messaging to handle commands

Formal messaging is used by the military to handle commands, and is primarily communication between roles and organisations rather than individuals.

Isode’s M-Switch SMTP MTA comes with a range of security and management capabilities that make it ideal for military messaging.

Operation over constrained networks is vital for many Military deployments. Isode offers a SMTP messaging solution based on the ACP142 military specification.

This provides optimised communication for both point-to-point and multicast networks, and operation in emission control or radio silence (EMCON). This can be operated over IP networks, such as satellite communication (Satcom) and fast radio links.

Isode also supports direct operation of STANAG 5066 to give optimal performance for high frequency (HF) radio.

Military messaging gateways

Isode provides three gateway products:

  • ACP127 Gateway: Based on Isode’s widely deployed M-Switch MTA and enables exchange of ACP127 messages with STANAG 4406 (including ACP145) and SMTP systems and operation over HF Radio using STANAG 5066
  • ACP145 Gateway: Provides STANAG 4406 edition 2 with digital signatures and security labels. It is designed to interconnect national military networks operating according to different profiles. M-Switch can be deployed as an ACP145 Gateway, including support for Security Labels and Message Digital Signatures
  • M-Switch MIXER: Provides a gateway between SMTP and standard STANAG 4406
  • XMPP for single-user use and large-scale deployments

The Swift XMPP client is suitable for single-user use and large-scale deployments in security conscious environments. Features include easy status setting, security label support, keyword / phrase highlighting and message acknowledgement.

The web and Android versions of the Harrier Military Messaging client, which is the latest product added to the Isode portfolio and currently on beta release, provides a number of military features. Some of these are simply presenting standard email capabilities in a military way, others follow the extended family of standards and in particular RFC 6477.
