1. BACKGROUND

This document has been developed generically. It must be tailored for the individual site. Specifically, only the version of figure 4-2 that corresponds to the site's size should be retained.


2. EXECUTIVE SUMMARY

The System/Network Security Concept of Operations (SECONOPS) is the first of the required ADP accreditation documentation, and all remaining documentation flows from and is based upon the documentation it provides. The SECONOPS identifies all of the intended users of the AIS or network, their clearance levels, access approvals, and need-to-know authorizations. This, plus the knowledge of the sensitivity of the information to be processed on the AIS/network, leads to the early identification of the expected mode of operation. This in turn results in the establishment of the preliminary minimum security requirements that must be achieved. Inputs to this document include the system purpose, the system description, mode of operation, and system accreditation schedule.


3. PURPOSE OF SYSTEM

3a. Mission Supported

[Site Specific: Describe the site's general mission.]

The mission of the DoDIIS AMHS is to provide:

3b. Requirement for the System

The AMHS improves automated message handling capabilities in the military intelligence community. It replaces the Modular Architecture for the eXchange of Intelligence (MAXI), the current DoDIIS standard, and other existing message handling systems within the community. The AMHS also provides automated message handling for sites that do not currently have an automated capability.

The AMHS enhances the process of intelligence data analysis and related product development at DoDIIS sites by providing sophisticated information management tools for analysts and system administrators. Site users will correlate message intelligence data more efficiently and effectively using current communication sources (automatically routed by the AMHS), and stored message data. Analysis will be comprehensive; documents will be produced, coordinated, and distributed easily. The system user, regardless of experience level, will be free to concentrate on product development and not be encumbered by the mechanics of system operation.


4. SYSTEM DESCRIPTION

4a. System Name and Location

[Site Specific: Provide as known the base address, building, room(s) for the system and any subsystems.]

4b. AMHS System Architecture

The generic architecture for an AMHS site is shown Figure 4-1. The site LAN interconnects a number of intelligence applications and user workstations. The architecture is based on the the client/server model. Each intelligence application is configured as a server that supports (application specific) client software on the user workstations.

The DoDIIS AMHS is one of these intelligence applications. Figure 4-1 shows that it receives and transmits formal message traffic via the Communications Support Processor (CSP).

Figure 4-1. Generic Site Architecture

[Site Specific: Small/Medium/Large Site] The AMHS Server Architecture is shown in Figure 4-2. The AMHS server is connected to the site LAN. The synchronous and asynchronous communication ports, magnetic disks and tape drives are shown as rectangles.

In the event that a redundant component fails or a spared single point of failure component fails, the site will warmswap the redundant component or replace the spared component and restart the system.

Figure 4-2. AMHS Hardware Architecture and External Interfaces

[Site Specific: miniAMHS site] The miniAMHS Server Architecture is generally illustrated in Figure 4-2. For the miniAMHS, however, the 20GB tape unit is replaced by a 6GB tape unit. All other system features are as depicted.

In the event that a redundant component fails or a spared single point of failure component fails, the site will warmswap the redundant component or replace the spared component and restart the system.

The hardware, software, firmware, and communication components of the AMHS are summarized in Table 4-1. Significant aspects of these components are elaborated in the following paragraphs.

Table 4-1 Summary of AMHS Architecture Components

4b (1) Hardware

Server: For a small, medium, or large AMHS configuration, the AMHS Server hardware is the DEC 2100, a RISC based processor running OSF/1. The miniAMHS employs a DEC 2300 RISC computer, also running OSF/1. Both computers are configured with a color terminal and LK401 keyboard. Each supports an internal thick Ethernet port, two serial communications ports, and a synchronous SCSI controller on the base system module.

Magnetic Disk Drive 2.1 GB: The 2.1 GB System is comprised of a Digital RZ28-MY 5400 rpm, random access, fixed-media disk drive arrangement. The drive is internally mounted and supports 2.1 GB formatted disks. Access is via a standard SCSI interface.

System Storage Component: The storage component consists of a BA350 mounted Digital 20 GByte Linear Tape drive(TZ87-VA). Access to the tape drive is via the standard SCSI bus interface. A 6 GB tape unit is included with the miniAMHS configuration.

RAID: The RAID provides fault tolerance and data reliability by incorporating a Redundant Array of Inexpensive Disks (RAID) level 5. With RAID 5, data and parity are "striped" across all disks in the array. Parity provides the data redundancy. The sub-system will tolerate the failure of a disk in the array. The AMHS RAID 5 is a controller based subsystem. RAID firmware is contained in the redundant controllers. The RAID controller is a SCSI device and attaches to the Fast SCSI controller in the DEC 2100 processor and provides 10 MBps bandwidth. The RAID controller provides seven fast SCSI-2 ports which support a maximum of four SCSI-2 drives per port. Modular chassis, redundant power supplies, and disk drives comprise the remainder of the subsystem. Access to the drives is via the SCSI bus interface.

RAID storage is an option for the miniAMHS configuration.

Vertical Frame (Rack): The Vertical Frame (Rack) is comprised of the AMCO FX 61 series heavy duty rack used to house and support the various hardware components which comprise the small, medium, and large AMHS configurations. The rack is equipped with a power controller, rear door, top exhaust fan, casters and levelers. Equipment frames may be bolted together to form multi-bay cabinets; however, small, medium, and large AMHS configurations can all be housed within a single FX 61 cabinet.

No rack is necessary for the miniAMHS configuration.

ACC Communications Device: This device is the hardware which supports the external communications requirements of the AMHS. It supports message traffic in DDCMP I2 and Ver. 4 protocols as well as FBIS and the ANPA protocol for wire services. The ACP 3020 supports four asynchronous and four synchronous serial ports. Communication protocols and device drivers for the external connections are supported in PROM.

4b (2) Software

The AMHS Server operating system is OSF/1.

TOPIC, a standard commercial product, is a text search engine. TOPIC supports both profiling and retrospective search. TOPIC will be used to enforce the Discretionary Access Control (DAC) requirements of the AMHS via System Profiles.

The AMHS provides a user interface on the user workstation to to support message composition and word procesing. The AMHS provides these via Aster*x, a standard commercial product.

Contractor developed software integrates the various commercial software products.

4b (3) Firmware

All firmware within the AMHS is part of standard commercial products that are delivered as components of standard commercial hardware.

4b (4) Communications

AMHS Communications: The AMHS directly supports four (4) external communication links: Communications Support Processor (CSP), the AGT Gateguard, wire services (AP, UPI, Reuters), and Foreign Broadcast Information System (FBIS). The AMHS also receives SMTP messages directly from the site LAN.

The AMHS communicates to the CSP via Generic Gateway using DDCMP and FDMP in accordance with the CSP ICD, CS-IC-11 88-01, Nov 1988.

The AMHS communicates with LDMX circuits via the AGT Gateguard accredited front end. The AGT Gateguard supports the kermit protocol for file transfer and the AMHS interfaces with the Gateguard in a receive only mode.

The AMHS receives wire service traffic from three wire services: Associated Press (AP), United Press International (UPI), and Reuters. The wire service communication links are read only and are received via an asynchronous RS232 line using American Newspaper Publishers Association (ANPA) message coding protocol.

The AMHS receives FBIS wire service messages. The FBIS communication link is read only and complies with FBIS ICD MPD-900-203A.

Site Communications: Site computing resources are interconnected via the site LAN. Through the CSP, the site supports an external communication link to the Automated Digital Network (AUTODIN) network. Through the AGT Gateguard, the site support an external communication link to the LDMX network.

[Site Specific: Describe Site LAN communications. The site LAN interconnects the site's user workstations and application servers. The LAN operates in the system high mode of operation.]

[Site Specific: Describe AUTODIN communications. The sites communicate to the AUTODIN network via the CSP. The CSP system is accredited and certified by USAF/INS and DCA, respectively, to handle DSSCS and GENSER record message traffic in accordance with DOI-103 and JANAP 128. USAF/INXDX conducts security accreditation tests on behalf of USAF/INS.]

4c. Systems Operations

4c (1) System/Subsystem Functions

Incoming Message Processing: The AMHS receives message traffic from the CSP, FBIS, LDMX via the AGT Gateguard, and the Wire Services, stores it on disk, and then distributes it based on the address list and special handling indicators appearing in the message headers.

The AMHS compares received traffic (formal message traffic, FBIS, and wire services) against stored user and system profiles. The AMHS disseminates messages to analysts' Message Queues (stored on AMHS Servers) based on the results of these comparisons. The AMHS sends alarms for high precedence messages directly to the active user workstations.

User Services: From their workstations, users can select and display messages from an In-Box, perform profile creation and refinement, formulate retrospective queries against the MDB and compose record messages for transmission.

Outgoing Message Processing: The AMHS Servers and the workstations cooperate during message coordination leading up to authorized release. When a message is approved for release, the AMHS transmits it to the CSP. After transmission, the AMHS compares the message with user and system profiles to determine local distribution. The AMHS also distributes released messages to local addresses supplied during message composition/release.

System Administration: The AMHS supports System Administrator operations for startup, shut down, AMHS user account management only, system advisories, and system monitoring. The AMHS also supports ISSO operations and profile administrator operations to manage and maintain user and system profiles.

4c (2) Functions performed jointly with other system(s)

[Site Specific: Provide a description of those functions and identify the systems with which these functions are performed jointly. Identify which system performs which function and operation. Include high level functional diagram(s).]

4c (3) Information Flow

The information flow within the AMHS is summarized within Table 4c (3)-1.
Item Description
a. Inputs Formal Message Traffic Formal messages arrive via CSP. The AMHS performs address-based distribution and profile-based distribution to deliver these to the appropriate users' Message Queues. Messages transmitted across the LDMX network are received by the AMHS through the AGT Gateguard front end system. Messages received via the Gateguard are processed identically as those messages delivered by the CSP.
Wire Service Traffic Wire Service traffic (read only) arrives from AP, UPI, and Reuters. The AMHS performs profile based distribution to deliver these to the appropriate user queues.
FBIS Traffic The AMHS performs profile based distribution to deliver FBIS traffic to the appropriate user queues.
Text Users will be able to "cut and paste" text between windows on their workstations. Text is an AMHS input when it is cut from another window and pasted into an AMHS window. User may also introduce ASCII text files to the AMHS for profiling by mailing documents to the AMHS server via SMTP.
b. Outputs Formal Message Traffic AMHS users compose formal messages for transmission over the AUTODIN network.
Text Users will be able to "cut and paste" text between windows on their workstations. Text is an AMHS output when it is cut from an AMHS window and pasted into another window. Users may also store AMHS generated/displayed files to personal storage areas by providing an appropriate path name.

7. SYSTEM SCOPE

This section explicitly delineates the division of responsibility between the AMHS system and the Site LAN in which it operates. This division of responsibility is significant since the AMHS is not being developed as an independent and isolated system. Rather, the AMHS is intended as a hardware and software add-on to existing environments that include user workstations and application servers connected via a Site LAN. (Recall Figure 4b-1, Generic Site Architecture.)

It is anticipated that these environments will have been previously accredited at System High. The AMHS does not attempt to override or duplicate the security features that are or ought to be present in the site environment (e.g. workstation login and deadman timeout mechanisms). The AMHS does, however, build on these existing security features where appropriate. Thus, AMHS identification and authentication relies on workstation login.

Table 7-1 identifies the scope of responsibility for the AMHS.
