Section 1.0: APPLICATION/SYSTEM Description and Identification

    1. Application/System Name and Identification: This section should state the name and mission of the application.

Distance Support Version 2.0 (DS2) Server.
The information system to be described in this Application Security Information (ASI) sheet is called the Distance Support 2.0 Server. DS2 Servers are deployed to IT-21 shipboard environments, and contain software specifically configured to enhance the ship’s intranet environment.

    1. Application/System Description: This section should describe what type of application it is (i.e. is it tech manual application, drawing application, training application, etc.).

      The DS2 Server is an intranet web-based information system used to support, distribute, and collect information in an Information Technology – 21 (IT-21) shipboard environment. This system hosts an intranet that maintains information such as: training courses, maintenance documents, and maintenance data collection, as well as morale and welfare support.
      Examples of content on the DS2 Server include: NetG courses for training, Advanced Technical Information System (ATIS) for technical documentation, along with PMS Scheduling (SKED) and Electronic Portable Maintenance Assistance (ePMA) for maintenance data collection. For morale and welfare support, DS2 hosts local web content that includes AnchorDesk.Navy.Mil, NKO.Navy.Mil and BUPERS. The DS2 Server has many other pages cached locally, which allows the warfighter to use the fast internal shipboard bandwidth as compared to using external ship bandwidth and expensive satellite time.
      The DS2 local intranet server provides this information to users during times that networking external to the ship is unavailable. When the ship has network connectivity, updates to the content can be obtained through the DS2 Amendment Server, located at Naval Surface Warfare Center (NSWC) Crane Division, Crane, Indiana.

    2. Functional Description: This section should provide a functional description of the application and the purpose or mission for which it will be used. Include functional diagrams of the application. Describe functions performed jointly with other systems and identify the other systems. Included functional diagrams should be at the macro-level. Provide the intended flows of data into the application, data manipulation, and product output. (Properly labeled diagrams or data flows can be included at the end of this document)

The Knowledge Management Center (KMC) and the DS2 Amendment Server are both located at NSWC Crane Division, while the DS2 Server is installed on a US Navy vessel.
The DS2 Server is designed to provide value-added solutions in shipboard environments. The DS2 system maintains current data with the KMC through the DS2 Amendment Server.
The DS2 system is a web-based information system used to support, distribute and collect information that exists in an IT-21 shipboard environment. The local intranet server (DS2 Server) then provides this off-line information to users during times that external network connectivity to the ship is unavailable. When the ship has external network connectivity, updates to the content on the DS2 Server can be obtained from DS2 Amendment Server, which provides timely and accurate information updates to the fleet. This central management of distance support relieves the burden of administration from local ship Information Technology (IT) personnel, and provides a highly trained workforce to maintain and manage information flow throughout each deployed DS2 shipboard system.
Amendments are comprised of changes to web based content, training materials, ship manuals, technical drawings, human resource data, and other data intended to reside on DS2 deployed servers. Basically, amendments are highly compressed files that are only readable by the deployed DS2 systems.

When a DS2 system is deployed, it is loaded with initial content from the KMC. When the content changes on the KMC, that change becomes the new amendment that is provided to all deployed DS2 systems via DS2 Amendment Server.

      1. Application/System Capabilities: This section should include the description of the capabilities of the application to be certified and accredited. These capabilities include functions the application should perform, desired interfaces and capabilities associated with those interfaces and the information to be processed.

The DS2 Server provides the ability to serve intranet documentation for maintenance, training, and other services that would normally be obtained via external network connectivity. It also collects data for delivery to shore via DS2 Amendment Server.
The following are capabilities of DS2 Server:

  • Unclassified Trusted Network Protection Policy (UTNP) compliant (All communications between the amendment server and the deployed DS2 Server are conducted using Secure Socket Layer (SSL) encryption over port 443.)

  • Receives amendments from the KMC through the DS2 Amendment Server

  • Sends updates from the ship to the DS2 Amendment Server

  • Provides useful intranet data to sailors, even when external network connectivity is unavailable

  • Synchronizes content between the ships and the KMC through the Amendment Server

    • Improvement of data validity

    • Lead time reduction

    • Labor and time savings

    • Fully integrated system

Data security and integrity maintained

      1. Application/System Criticality: This section should describe the overall criticality of the application’s capability to support mission accomplishments.

The DS2 Server is a mission support system. The DS2 Server enables Naval Sea Systems Command (NAVSEA) to provide reliable support to the Fleet.

The criticality of the DS2 Server is Mission Assurance Category III. The loss of the DS2 Server is equivalent in severity to losing email and web-browsing capability. Impact includes the inability to retrieve documents quickly resulting in delays and loss of productivity to intranet users. The information served by DS2 is necessary for conducting of day-to-day business, but does not materially affect support to deployed or contingency forces in the short-term. The loss of integrity or availability can be tolerated or overcome without significant impacts on mission effectiveness or operational readiness. The consequences could include the delay or degradation of services or commodities enabling routine activities.

      1. Classification and Sensitivity of Data Processed: This section should describe the security classification of the data processed and any additional sensitivity labels or warnings that accompany the data.

The data processed by the DS2 Server is unclassified. However, since the system contains business sensitive, For Official Use Only (FOUO), and Not Releasable to Foreign Nationals (NOFORN) data, the system is categorized as Controlled Unclassified Information (CUI). All files, programs, tables and related software are protected in accordance with existing standards of the Department of Defense (DOD), the Department of the Navy (DON), NAVSEA, and NSWC Crane Division.

      1. Application/System User Description and Clearance Levels: This section should describe the personnel that are to be the primary users of the application and data on the system or network, and the necessary clearance levels that are required to access the data on the system or network.

Granting of access to data and/or functionality is based upon “need-to-know” and “least privilege.” Security requires operators to log on and off at the start and completion of each approved work period. All users of the DS2 Server must meet the local Automated Data Processing (ADP) security policies of the installed environment (the ship’s ADP policy). The DS2 Server is joined to the ship’s domain.
Any restricted data is password protected. Requests for access may be granted by ship’s force after a background check. Examples of this rule would include the access controls provided by ATIS, SKED, ePMA, Navy Knowledge Online (NKO), and certain web content.
For security purposes, DS2 users can be divided into two broad categories:

Ordinary Users. Ordinary users may be government, military, or contractor personnel that utilize DS2 Server resources to conduct official business. Ordinary users are not tasked with security or system administration. Because DS2 Server data is processed at the CUI level, no special government clearance levels are necessary. Access to information is on a “need-to-know” basis and the principle of “least privilege” applies when granting access to users.

System and Security Managers. System and security managers are government or military personnel that perform security and/or administration for one or more of DS2 resources. Although no formal government clearance is required, system and security managers are strongly encouraged to have a favorable National Agency Check Inquiry (NACI), or a DoD clearance of classified or higher. Access to information is on a “need-to-know” basis and the principle of least privilege applies.

      1. Life Cycle of the Application/System: This section should include the description of the Application/System Development Life Cycle, where your application is relevant to the application development life cycle, and the plans for the near future.

There is no planned retirement for the Distance Support 2.0 system. Hardware and software upgrades are to be updated as needed to satisfy growth requirements.
Future plans include the enablement of Public Key Infrastructure (PKI) authentication. Those services shall be implemented according to Navy instructions, and upon shipboard implementation of PKI authentication. The software to accomplish enablement of PKI authentication on DS2 is in place, but not turned on at this time. As PKI is implemented aboard ship this software will be enabled as appropriate on a per ship basis.
Certificate enabled communications are in use while the DS2 Server reaches back to the DS2 Amendment Server.
As of right now, there is no Secure Internet Protocol Router Network (SIPRNet) component of the Distance Support 2.0 system. If in the future a need exists, a new System Security Authorization Agreement shall be written for that component, and this SSAA shall be updated to make reference to that SSAA.

DS2 is comprised of Commercial Off-The-Shelf (COTS) and Government Off-The-Shelf (GOTS) software, along with specially tailored applications. The expected life cycle of the existing components in this configuration is a minimum of five (5) years. As required, additional COTS equipment may be acquired and integrated into the configuration or used to replace existing components.

Currently, the DS2 Server is past the developmental stage, and is ready for deployment and connection to the Integrated Shipboard Network System (ISNS) aboard ship.

      1. Application/System CONOPS Summary: This section should include a brief summary of the Concept of Operations for the application. What the application is, its major mission, who it supports, and how its users will utilize it when operational.

The goal of the DS2 Server is to deliver a knowledge management system that integrates into the framework of a ship's day-to-day work environment. Critical information distributed in documents, training, and feedback will be quickly available even without continuous external network connectivity. The DS2 server will be used as the primary gateway to that information, while using the smallest amount of network bandwidth possible.
The DS2 Server integrates with the existing shipboard environment. It utilizes the ISNS shipboard network, and travels over the ships encrypted Inmarsat satellite link. IT-21 NOCs provide firewall protection for the ISNS shipboard LAN and the DS2 Server. The DS2 utilizes encrypted SSL through port 443, which is Navy UTN (Unclassified Trusted Network) Protect Policy Firewall compliant, to communicate with the Distance Support Amendment server. Please see Figure 1 at the end of this document for a diagram of this interaction.


DS2 Server. DS2 documents and files are stored on the Windows 2000 NTFS File System to allow scanning for viruses, access restrictions, and logging. The disaster recovery method is to ship re-imaged hard disks from the design agent NSWC Crane Division. See Figure 1 at the end of this document for a connectivity diagram of the DS2 Server.
Deployed DS2 Environment. The deployed DS2 server is connected to the IT-21 unclassified network. Because it is considered a member of the ship’s domain, the deployed DS2 server is protected by ISNS/IT-21 security features (specifically a UNTProtect compliant firewall), already in place on the vessel and in the Network Operations Center.
DS2 Innovation Test Lab. Hardware associated with the Distance Support Innovation Test Lab includes servers, workstations, peripherals, and communication equipment required to exchange data. Security protection, allowing the Distance Support Innovation Test Lab to traverse another activity’s firewall boundary, is controlled at that activity’s discretion. Connection to the Distance Support Innovation Test Lab by other government and commercial entities is currently controlled by corporate and local firewalls. Firewalls enforce a Unclassified Trusted Network Protection Policy that can be updated by authorized personnel to meet changing requirements. Firewalls that protect access to NSWC Crane Division are controlled by the ISSM. The DS2 firewall administrator controls the firewall protecting the Distance Support Innovation Test Lab. All changes to the firewall must be approved through the ISSM. All external connectivity is provided by a Defense Information Switch Network (DISN) provisioned 12 Megabit Non-Secure Internet Protocol Router Network (NIPRNet) circuit.

    1. Firmware: This section should describe the firmware that is stored permanently in a hardware Device that allows reading and executing the software, but not writing or modifying it (PROM and EPROM).


    1. Application/System Interfaces and External Connections: This section should describe the application’s external interfaces. The description should include a statement of the purpose of the interface and the relationship between the interface and the application.

See Figure 2: Intra Ship Connectivity Diagram at the end of this document

See Figure 3: Content Update with DS 2.0 Amendment Server at the end of this document

    1. Data Flow (Including Data Flow Diagrams): This section should include the data flow descriptions that show the input and output of all types of data associated with the application, and how the users interface. A line drawing of the flows should be included. (Properly labeled diagrams or data flows can be included at the end of this document)

See Figure 4: Data Flow Diagram at the end of this document.

Examples of information that is relayed by the DS2 Server would be:

  • Discussion threads into NKO Afloat (to and from the ship)

  • Maintenance schedule data in SKED (from the ship)

  • Preventative maintenance data for ePMA (from the ship)

  • Integrated Condition Assessment System (ICAS) sensor data files (from the ship)

  • Data files (to and from the ship)

  • Web and data content (to and from the ship)

The Distance Support platform is used as a secure, reliable transport between ship and shore. Files can be transferred securely because of the encryption, and reliably because of the auto-resuming features of the DS2 Update program and Tumbleweed Secure File Transfer Protocol (FTP) Client.

The Distance Support 2.0 Server communicates with the Distance Support Amendment Server via HTTPS.

The Distance Support Amendment Server is fully described and accredited.

    1. Accreditation Boundary: This section should describe the boundaries of your application to be accredited. Be sure to include all components that are part of your system and inside the boundary, and if necessary, list all of the components that may be in question whether they are inside or outside the certification boundary.

The DS2 server is created in the Distance Support Innovation Test Lab and deployed to US Navy ships. The physical accreditation boundary is confined to DS2 Server.
A System Security Authorization Agreement (SSAA) covers the Distance Support 2.0 Server in its current configuration. The configuration of software has not changed since SPAWAR Automated Test Facility (ATF) testing. This configuration is comprised of the hardware in Section 2.1, the software in section 2.2, and the interfaces depicted in diagrams at the end of this document. The Distance Support 2.0 Server has been issued a SSIL number from SPAWAR ATF testing.


The Disaster Recovery Plan (also known as a Contingency Plan) provides essential guidance for contingency preparations, emergency reactions, backup operations and the restoration of services following the occurrence of a disaster situation related to this application. It basically answers the question of what would need to be done in order to get this application back up and running if there was a hardware failure, software failure, natural disaster or human error. Knowing this information will assist the ship in recovering the application while underway.

    1. Identify all the necessary resources and procedures for restoring the application back to normal conditions.

Significant factors exist that help DS 2.0 Server minimize the effects of fire, flooding, battle damage and other catastrophes. DS 2.0 Server and peripherals consist of ruggedized components and enclosures, which are normally located in areas with restricted access. To further reduce the potential effects of disaster to DS 2.0 Server components and operators, the following procedures should be implemented:

  • For the protection of DS 2.0 Server operators and administrators, evacuation routes should be prominently posted and evacuation drills held on a regular basis.

  • Where possible, personnel should be trained in fire-fighting and damage control techniques. At a minimum, all personnel should be trained in fire, flooding and accident prevention.

  • Personnel who regularly occupy areas where DS 2.0 Server equipment is installed should be trained on the proper procedures for securing ventilation and power to the DS 2.0 Server in the event of an emergency.

  • Personnel should be well versed in Command/Facility emergency procedures, and know which personnel to contact or numbers to call in the event of an emergency.

  • To protect the DS 2.0 Server from malicious attacks, various levels of system access are established. Passwords for Power Users and Administrators should be well guarded and regularly changed.

  • To ensure recovery, DS 2.0 Server backup software, restoration disks and removable media should be maintained in locked, fire-resistant or other secure metal containers.

DS 2.0 Server Backup Procedures

DS 2.0 Server backup procedures begin at installation. The site where the DS 2.0 Server is installed is supplied with copies of the DS 2.0 Server software Installation disks.

Additionally, the following backup procedures are recommended:

  • Operating System recovery disks should be created according to the procedures outlined in the applicable operating systems Installation and Configuration Guide.

  • The DS 2.0 Server Systems Administrator should ensure that backups are performed on a routine basis with a weekly full backup maintained.

  • As previously stated, all DS 2.0 Server backups, restoration disks and removable media should be maintained in locked, fire-resistant or other secure metal containers.

DS 2.0 Server Restoration Procedures

The process of recovery for DS 2.0 Server following a disaster or system failure is the repair/replacement of hardware assets, the reinstallation of DS 2.0 Server software, and the restoration of DS 2.0 Server databases. The following steps detail the recommended procedures for DS 2.0 Server system recovery:

  • A thorough investigation should be conducted by a qualified DS 2.0 Server System Administrator and/or authorized computer repair technician to determine the extent of damage to DS 2.0 Server hardware assets.

  • To preclude further damage to DS 2.0 Server assets or personnel, ensure power and other required system services have been restored and are stable, prior to initiating repairs.

  • After verifying that the affected DS 2.0 Server devices and peripherals are operational, the DS 2.0 Server System Administrator should begin the process of reinstallation/recovery of DS 2.0 Server software and databases. This process can be accomplished by following the procedures for “Installing DS 2.0 Server software” detailed in the DS 2.0 Server Software Installation Guide.

  • The final process is to restore any DS 2.0 Server database backups as described in the DS 2.0 Server System Administrator Manual.

    1. Identify a list of the files, folders, databases, and/or configuration files that need to be backed up on a regular basis.

In the ServerSoftware folder: Serv.root.
In the Data Files sub-folder: AggregatorData.root, WeblogData.root, and WeblogsComData.root.







The entire HTM subdirectory.

The entire Docs subdirectory.

AggregatorData.root and the Service4.exe files have to be in same folder to run.

AggregatorData.root also relies on the files in HTM and Docs subdirectory folder.
