2. Thoughts on our network
Duane Guilbeau
Network Supervisor

3. Topics to Cover
Security
Home vs. Enterprise
Wireless

4. Security, Why bother? We have personal info on 14,000 students
No credit history, no debt, no loan defaults
We are a target
Network dependency
Testing, grade reporting, food services, purchasing, cameras, clocks, door locks, air conditioning, www
No dedicated security team
Not proactively monitoring traffic flows
Security is everyone’s problem
Physical and electronic

5. Security - Passwords Your username/ password identify YOU
Don’t share passwords
No weak passwords
“Password”, nothing, names
Don’t let students share passwords
No acceptable use form = no internet
Generic Accounts
How to change your password
Control - Alt - Delete

6. Security - Email Phishing - preying on trust / inattention
FedEx, UPS, IRS, PayPal
Don’t click the links
Ransom ware, back doors
We’ve been affected: maintenance, sped server

7. Home vs. Enterprise Networks
Our network is not an extension of your home
Go to your bank, see if you can use their Wi-Fi.
Everything has to work together
Cell phones, tablets, laptops, printers,
Cameras, clocks, a/c, door locks
Active Directory, Web Filter, Radius, vlans,
streaming, SNMP, routing, ACL
Computers from Office Depot and Wal-mart

12. Wireless 1450 access points parish wide IPSB-wifi Uses WPA2-Enterprise
It’s a whole second network, no additional staff
IPSB-wifi
Use your username and password to login
Uses WPA2-Enterprise
Not compatible with Direct Connect
Wireless printers, home electronics
Uses s and ac
Slower standards destroy wireless throughput
a/b/g/n/s/ac

13. Wireless - Why For testing For future BYOD or 1:1 projects
For teacher mobility (wires in wrong places)
Not for:
Cell phones, updates
Because you don’t want to see the blue wires
To watch movies on your tablet

14. Closing Be suspicious of email Much more complex than a home network
Network is a shared resource
