## Telecommunications System/Security (2004/06 Census Tests)

**FDCA Symposium**
**Breakout Session 2**
**February 28, 2005**
**Ken Walker**
**FDCA Core Team**

## Session Objectives:

- -  Provide Overview of the 2004 Test Hand Held Computer (HHC)
-  -  Provide an 2004 Telecommunications/Data Transmission System Overview
- -   Describe the 2004 Systems Security Features
-  -	Highlight “Lessons Learned” from the 2004 Test

## 2004 Hand Held Computer 

**	**Hardware Highlights:
- 		Hewlett Packard IPAQ 3950,  64 MB RAM, 32 MB ROM, Single 	Secure Digital (SD) Card Slot, Single Compact Flash (CF) Card 	Slot, Holux GPS, Receiver (CF), HP 56 Kbps Modem (CF), 256 	MB Storage Card (SD), 3 Batteries for 12 hours Continuous 	Usage, 2 Device/Battery Charges (110 AC & 12 Volt DC-Auto)
- 	HHC Software Highlights:
- 		Microsoft Windows CE/Pocket PC 2.0 FileCrypto Data 	Encryption 2.03,  Win CEZip File Compression 1.0, PC-cillin 	Virus Protection 2.0, ArcPad 6.0.3, Acrobat Reader 1.0, Afaria 	Client 4.51,  Pocket Excel,  Pocket Word, Assignment 	Management System (AMS), Census Mapping Software

## 2004 Hand Held Computer (Cont)

- Design Highlights:
- 	- All Software Stored/Executed from SD Card – Except AMS
- 	- SD Cards Contained Complete HHC Image
- 	- Device is not User Dependent
- 	- Full Data Back-up and Recovery Functionality
- 		-  Title 13 Data Stored on Both the HHC and SD Card
** **Lessons Learned:
- 	- Users had Trouble Connecting Parts
- 	- “Final Image” was Not Completed
- 	-  HHC was Difficult to Learn/Use
- 	-  Few Products Available

## Telecommunications/Data Transmission Infrastructure

## 2004 Transmission Summary

- 	1. HHC Conducts Dial-in to BOC RADIUS (Remote Access) System
- 	2. Enumerator’s Transmission ID/Password Authenticate
- 	3. Access is Granted and SSL(Secure-Socket Layer) Connection is          Established with the Afaria System
- 	4. Data Transmission Sequence:
- 		- Afaria System Pulls Completed Work from HHC
- 		- Afaria System Pushes New Software to HHC
- 		- Afaria System Pushes New Assignments/LMRs to HHC
- 	5. Afaria Disconnects HHC
- 	6. Post Transmission Processing Executes on HHC
- 	7. HHC Displays Transmission Status Message (Failed/Successful)
- 	8. Enumerator Resets HHC, Ready to Go!

##  Transmission Lessons Learned

- 		- Lost links
- 			- Initial Transmission too Large
- 			- Unable to Load Test Asynchronous Dial-up
- 			- Instability of Device/Async Transmission
- 		- Password Configuration
- 			- Two Passwords-Device Password vs System 			   Password
- 			- Inability to Change System Password
- 		- Initial Preset Transmission Error’s
- 		- Ability to Monitor End-to-End Transmissions

## 2004 Security Features 

- Password Protection:
- 		- Device Access and Transmission Passwords 	Implemented
- 		- Inactivity Lock-out:
- 		- 3 Minutes of Inactivity Invokes Screen Lockout
- 		- Device Password Must Be Entered to Resume
- 		- No Effect on Open Session/Work
-  HHC Data Encryption:
- 		- National Security Agency AES 128 Bit and FIPS 140-2 	   	Compliant
- 		- Real-Time Encryption
- 		- All Title 13 Data (Respondent Data & Maps) is Encrypted!

##  2004 Security Features 

- Data Transmission:
- 		- Secure Socket Layer (SSL) Connection
- 		- Established at Dial-in/Enumerator Authentication
- 		- SSL Connection is a “Secure Pipe” Between HHC and Afaria
- 		- Implementation is FIPS 140 Compliant
