Telecommunications Strategy
■ Short Term
■ Investigate several options for capturing shrinking telephone
revenues.
■ Do two revenue-sharing contracts (Nextel & AT&T)
■ Seek lower-cost LD rates.
■ Extend Verizon contract at same or lower rates for two years
(June ’07) to “lock in” low Centrex rates.
■ Investigate several options for enhancing voice service.
■ VoIP Centrex
■ Do VoIP SIP as an app on PennNet (Broadsoft)
■ Do VoIP SIP as an app on PennNet (open source)
11/17/03
6
Telecommunications Strategy
(Continued)
■ Mid term (1-3 years)
■ Do all network readiness work.
■ NGP (enhanced capacity, reliability, redundancy)
■ Upgrade electronics
■ Prepare staff and customers for transition.
■ Do VoIP pilots in College Houses and elsewhere.
■ Do softphone pilot of VoIP using campus wireless
network (Dartmouth model).
11/17/03
7
Telecommunications Strategy
(Continued)
■ Long term (5 years)
■ Full deployment of VoIP with all associated
services including:
■ Unified messaging
■ “Follow me” features (Presence)
■ Enhanced ACDs
■ Video picture phone calls
■ Softphones
11/17/03
8
Telecommunications StrategyNext Steps
■ Expand VoIP SIP pilot within N&T from 20 to
80 phones.
■ Expand pilots beyond N&T to ISC and some
external customers.
■
■
■
■
■
11/17/03

10
Security Strategies
■ Implement a multi-layered security-in-depth
architecture consisting of:
■ Host security
■ Security out-of the box
■ Patch management, anti-virus, strong passwords
■
■
■
■
■
11/17/03
Network authentication and authorization
Anti-virus
Firewalls
Intrusion detection
Improved incident response processes
11
Security Strategies (Continued)
■ Establish policies that resolve privacy concerns and
provide a mandate to justify funding a security in
depth architecture.
■ Provide tools and resources to empower LSPs to
implement these policies
■
■
■
■
■
11/17/03
Patch management service
Personal and workstation/server firewall and VPN standards
VLAN Support
Antivirus tools for large mail servers
Education and training

ISC Security Progress
■
■
■
■
■
■
ISC, in collaboration with its customers, is developing
a multi-year strategy for campus computing security.
Support for VLAN network topology for fee in support
of local firewalls.
Support for short-term filtering on edge routers for
problematic services.
Virus scanning on POBOX.
Campus-wide and focused, critical host vulnerability
scanning and reporting.
Security incident response
11/17/03
13
Security Plans/Near-term
■
■
■
■
■
Implement a PennNet host security policy
mandating patch management, anti-virus software
and strong desktop/server passwords.
Take proposals to NPC & IT Roundtable for
intrusion-detection and campus-wide virus email
scanning.
Help leverage virus scanning service for other
campus email servers. ($5 per account per year)
Identify vendors/consultants who can assist with
implementation of local firewalls on a for-fee basis.
Evaluation to identify standard firewall and VPN
software.
11/17/03
14
Security Plans/Near-term (Continued)
■ Improve notification and disconnect/reconnect
processes
■ Develop tools to rapidly associate wallplates with IP addresses.
■ Improved assignments accuracy and support quick lookups
■ Reduce the number of unregistered IP addresses
■ Targeted deployment of PennKey authenticated network access in
College Houses, GreekNet, Library and other public spaces. ($100k for
wireless)
■ Research ways of ensuring security of newly connected
machines:
■ Vulnerability scan of machines as they connect to PennNet
■ Network authorization: Ability to block infected/vulnerable
machines based on MAC address
11/17/03
15
Security Plans/Medium-term
■ Improved security on Fall Truckload disk images.
■ Evaluate personal firewalls with goal of sharing
information among, and making recommendations for,
local support providers.
■ Patch management
■ ISC to run opt-in software update service for fee. ($28k year)
■ In lieu of patch testing, Penn to wait 1-2 days before
implementing new patches on ISC run SUS server except in
cases where ISC Information Security determines immediate
release of patch is critical.
■ ISC to do more education and training. ($20k year)
11/17/03
16
Security Plans/Medium-term
■
■
■
■
11/17/03
Pursue volume discount pricing for patch management
software as appropriate based on the recommendations of
the patch management evaluation effort.
Additional TSS second-tier support for LSPs. ($15k)
ISC costs to manage port disconnects, reconnects associated
with enforcement of patch management policy. ($150$200k FY ‘05; $100k ongoing)
Similar local costs possible with supporting enforcement of
patch management policy.
17
Security/Medium-term (Continued)
■
■
■
■
■
Evaluate and recommend server and workgroup
firewalls.
Select standard VPN and firewall software.
Determine if ISC should operate a centrally managed
firewall service.
Develop a migration strategy and cost proposals to
move towards campus-wide network authentication
on both the wired and wireless networks.
After policy is accepted, pilot Intrusion-detection.
($100k)
11/17/03
18
Security Plans/Long-term
■
■
Implement campus-wide authentication (PennKey) on
both the wired ($2M) and wireless ($100k) networks.
Evaluate a network design and migration strategy
that better balances availability against security, and
capable of supporting broader intrusion detection and
firewalling.

Strategy
■ Wireless as an “overlay” technology - not
replacement for wired.
■ Scalable & Secure Solutions
■ Use Enterprise Class Technologies
■ Cisco AP350 & Newer 1200 AP
■
■
■
■
Adjustable Signal Strength
Stability
Monitoring & Statistics
Tri-Band Capabilities
■ Staged Approach
■ Standards Based Products
■ Avoid being locked in to single vendor
■ Cards that Comply with Wi-Fi Standards

21
Challenges
■ Funding
■ No Central Funding
■ Slower Roll Out in Some Areas
■ Should we subsidize public wireless IP addresses? ($50k)
■ Should we subsidize wireless authentication? ($100k)
■ Security
■ Authenticated Access
■ Data Encryption Lacking
■ Not able yet to do authorization with wireless authentication.
■ Support
■ Challenges supporting mobile users.

Current Status
■ Authentication Gateway Tests
■ Testing with New Vendor Going Well
■ Short Term Plans
■

■
■
■
Work with Both Vendors (support exiting base)
Deployed New Auth. Device at Vance Hall 11/11
Upgraded OS on Existing Gateways on 11/13.
Expand Larger Pilot and another wLAN Mid December
Van Pelt PennKey authentication possible for next semester.
■ Long Term Plans
■ Resume replacement of MAC Authentication
■ Hit Target Dates for FY04
■ Pursue Strategic Plans
■ Determining funding model for a full-campus deployment
