SIM - A robust  Instant Messaging and Chat Solution designed to meet the requirements of operational military environments

Integrated with Microsoft Live Communication Server (LCS), SIM’s principal function is to provide an enhanced level of information assurance for IM / Chat sessions. It achieves this through the addition of protective marking for Chat Rooms and security clearance / access checks for users to ensure they can only see and enter a room for which they have the appropriate security clearance. SIM also supports conversation archive, persistence and audit.

Key Features

• User Authentication - SIM uses optional smart cards and passwords as well as Windows authenticated log-on to ensure users are who they claim to be.
• Security Labelling and Clearance Control - All Chat Rooms have a protective classification mark and all users have a security clearance. Users are therefore only able to see and enter room sessions for which they are cleared.
• Zero-Footprint Web Client Interface - SIM uses a web browser, such as Microsoft Internet Explorer, as its client interface, therefore, it does not require any pre-loaded applications or dynamic downloads before it can be used.
• Lockable Chat Rooms - All rooms can be ‘locked’ preventing other cleared but unwanted individuals joining. 
• Guest Invitations - Chat Room participants can ‘invite’ a non-cleared guest into the room to join the conversation, for example to give their expertise on meteorological reports. Whilst the guest is in the room, the identities of all the other participants are hidden from the guest’s view, and the room’s classification is lowered appropriately. The guests also cannot see the conversation prior to them joining the room.
• Guest Conversation Filtering - When a guest of a lower clearance level is in the Chat Room, the other members can see that they are now operating at a lower clearance level.
• Conversation Persistence - When a new cleared attendee joins a Chat Room session, they can use the ‘scroll-back’ facility to easily see the full conversation’s history, allowing them quickly to catch-up.
• Secure IM Booths - If there are only two participants, SIM allows for these individuals to move into a Secure Booth for one-to-one conversation through the IM Booth facility.
• Secure Archive and Audit - The full conversation from Chat Rooms and Secure IM Booths can be archived to an SQL server database. The archive contains the full conversation history as well as the participants, leavers and joiners, and all entries are date and time-stamped for ease of retrieval and audit trails.
