Research Data Protection:
An Overview of the VCUeRA System
Jim Ward
Director of Research Information Systems
Office of Research
What Types of Data Protection?
• Physical Protection
• Physical access and environmental controls
• Network Protection
• Network attacks and threats
• Application Protection
• Authentication and Authorization
• Hardware Protection
• Hardware failures, backups and redundancy
Current Configuration
• Office of Research currently manages eleven
servers
• Windows 2003 Server
• The VCUeRA production system consists of
four servers
• Two Web servers
• IIS (Internet Information Services) 6.0
• Two Database servers
• SQL Server 2000
• Database size: 95GB (24 DVDs or 132 CDs)
Physical Security
• Located at University Computer Center
• Building and VCU Computer Center have 24 hour
security and access
• Require passwords at
system console
• Renamed administrator’s
account
• Disable guest accounts
Physical Security Cont.
• Environmental Controls
• Dedicated air conditioning and noise containment
• Dedicated Power and UPS
• All servers have redundant power supplies
• Servers should be on a dedicated circuit
• Multiple circuits are installed at Computer Center
• UPS (Uninterruptable Power Supply)
• Computer Center has a dedicate USP for entire center
Network Security
• VLAN (Virtual Local Area Network)
•
•
•
•
Server VLAN
Desktop VLAN (SECNet)
Wireless VLAN
Residence Hall VLAN

Desktop VLAN
VCU Network
Wireless VLAN
Residence Hall VLAN
Network Security Cont.
• Firewall – defines which ports the system is
allowed to use
Only allow
Web access
from
anywhere
Only allow web
access from VCU
address
• Web Servers
• Only allow access to http and
https ports from anywhere
• Database Servers
• Only allow access to SQL
port from web server
• Implemented using two firewalls
• Network based (controlled
by VCU Network Services)
• Server based (installed on
server and controlled by OR
IT staff)
Application Security
• Secure HTTP (HTTPS)
• A secure method for viewing web pages
• Same technology as used by banks and other
online commercial retailers
• At VCU, a certificate must be issued and installed
on each server yearly
• A certificate is issued for https://vcuera.research.vcu.edu
• Application Authentication
• Process for determining user identity
• VCUeRA uses VCU eID
Application Security Cont.
• Application Authorization
• Process by which user is granted access to specific area of
the application
• VCUeRA uses application roles
• Access granted to a specific department or school requires
department chair or school dean approval
• Access to a entire module requires approval from the Vice President
for Research
Hardware Failures
• Disk Failures
• RAID
• Web servers use RAID 1
• Database servers use RAID 5 with hot spare
• Sever Log Monitoring
• Software installed to monitor servers log (application,
security, system log)
• Sends e-mail notification when an error or warning is written
to any server log
• DELL Open Manage
• Monitors server for dell specific hardware issues and writes
error to server logs when error occurs
Backups
• Backups of Servers
• VCU has a dedicated VLAN for backups and
requires using a second dedicated network card
• Perform nightly incremental backups using
Computer Center’s Tivoli Storage Management
• Additional Database Backups
• A full copy of the database is created each night on
the server (takes about 15 minutes)
• Every 20 minutes a copy of any database changes
are copied to disk
• These are backed up using Tivoli
Redundancy
• Website
• Two servers acting as one
• If one fails, we can continue to function on other
• Database
• The files created from the changes backup are also
copied to the second database server.
• If a manual restore of the production database was
required, it would take 8-10 hours.
• 4-5 hours to restore the backup file from tape, plus
• 4-5 hours to restore the database
• Can restore in a little as 20 minutes
Additional Protections
• Security Patches
• Security patches are manually installed within 1
week of release from Microsoft
• Usually installed after hours
• Remote Access
• On campus, use Remote Desktop for remote
administration of servers
• Off campus, a VPN (Virtual Private Network)
session is required for all administrative functions

Future Plans
• Perform yearly vulnerability scans by
Technology Services
• System Logs sent to Technology Services
MARS system (Technology Services’
Monitoring, Analysis and Response System)
• Move two servers to Computer Center’s hot site
• Second web server
• Backup database server
What does this mean for me?
• Data needs to be protected with numerous
layers of security
• Make backups of your data and secure them
• If you require a server or storage space, you
should contact Technology Services at
http://www.ucc.vcu.edu/
• Provide storage space
• Provide server support, maintenance, and security
for dedicated servers at a cost of $100 per server
per month
• DO NOT install a server in your office
Inquisite
• Accounts are distributed to departments
• Annual fee of $800 per year per account
• Department assigns an account administrator
• Manage all surveys for account
• Serve as primary contact for department regarding
Inquisite
• Investigators can request an account separate
• Still need to designate an account administrator
• Still required to pay $800 per year per account
