The Security BILL HUSTED 09-18-2002 The Atlanta Journal and Constitution
“On a quick drive through Atlanta---from its residential streets
to the downtown business districts---even a klutz of a computer hacker has literallyhundreds of chances to view everything from
your credit card informationto confidential business”

Focus on SecurityGC&SU announces WLAN
Includes future plans for enhanced security
Wireless security problems close to home?
Atlanta TV reports possible WLAN security breach at a key location
GC&SU temporarily curtails WLAN access
Expedites plans for security solution
Meetinghouse Solution

The Challenges
Immaturity of testing equipment
Pioneering efforts … Traffic simulation
Historical buildings
Camouflaged installation and transmission
• Roof top antennas (white cabling blending into architecture)
• Penetration issues in older buildings and the great outdoors
Enforcing networking policies
Required 802.1X security software (manual configuration)
• Required 128 bit WEP NICs compatible with RoamAbout R2
• Mixed operating systems, NICs, and firmware versions
• Dealing with users denied network access

Next Steps - Continued Success
Continue Partnership
• Collaborative development
Geographical Expansion
• Main Street, Milledgeville, GA
• New Campus Residence Apartments
• The Historic District
• Rural Georgia
Feature Expansion
• Enhanced wireless security
• PDAs - campus police & physical plant
• Innovation contest – “Best Practices”

Lifespan of 802.11b, 802.11a, 802.11g, 802.11? Upgradeability Compatibility Expanding availability of end user devices Competition Signal interference Regulatory restrictions Funding to stay current Differences between higher education and the corporate
environment The digital divide between the “have and have not”
institutions
The Future Network Issues
Georgia College & State UniversityGeorgia’s Public Liberal Arts University
Allow time for researching and evaluating emerging technologies
It will take longer than you thought it would!!! Real life in higher education is not the same as real life in the
corporate world Homogeneous hardware deployment streamlines the effort Be prepared to consider external factors The final product will be the result of continuous
reengineering Partnerships require an ongoing, open communication plan If you build it “They WILL come”
The Lessons Learned
Georgia College & State UniversityGeorgia’s Public Liberal Arts University
Mobility and seamless coverage Flexibility for educational locations Every classroom becomes an electronic classroom Reduces overload on lab facilities No “Is this a wireless area?” questions Addresses the “Total College Experience” Opportunities for innovative activities Opportunities for cooperative corporate interaction Network contingency/redundancy “Take the office to the students” Develop “Learning Communities” And....................................................
The Benefits
