5. 2005/6 outcome – efficiency connections vs time

6. Methodologies in use to address this challenge 1.Resist need to network private machines 2.Manage machines as standard corporate machines 3.Outsource residential network 4.Manage the unmanaged by using an emerging technology framework, Network Admission Control (NAC) to address challenges

7. Network Admission Control (NAC) - the wider environment Analysis: Network Access Control Network Computing, October 06, 2006 “NAC (network access control) enforcement products will grow to $3.9 billion by 2008 from $323 million last year--that's more than 1,100 percent growth” Lippis Report Issue 69: 2007 Is The Year of Network Access Control Oct 16, 2006 by Nick Lippis So is 2007 the year of NAC? 1)NAC solves real problems 2)NAC technology works 3)Enterprises are deploying NAC. The data points are building and the trend line is becoming clear. 2007 is the year of NAC.

8. TCD Self Service NAC project objectives From start October 2006: Improve quality of service for students connecting computers to the College network Reduce IS Services staff involvement Maintain or enhance Network Security Provision of dynamic network administration and network security information

9. TCD Self Service NAC scope target customers and areas Initial scope Extended scope Desirable – Wireless/VPN Not under considerations – Guest/EduRoam

10. TCD Self Service NAC project approach Surveyed current market place and Institutions using NAC Solutions identified – approx 20 Short listed - 6 Arranged presentations, trials and site visits Submitted project proposal including business case to Senior Management Initiated restricted Request For Proposals, closing 8 th June

11. TCD Self Service NAC project business case Model 1 Transaction costs Model 2 Staff equivalents Model 3 Qualitative benefits

29. TCD Self service NAC Primary outcome – ability to meet customer needs efficiency

30. TCD Self service NAC Economic perspective outcome Assume total Capex and Opex cost over three years excluding labour Assume cost per user in bands €0-10, €10-25, €25-50, €50-75 and €75-100 Cost per user currently €50-75 but €0-10 achievable within 3 years

31. TCD Self service NAC outcomes Repositioned to better meet network connectivity needs of students both effectively and efficiently as these needs evolve over time Control and support high numbers of “unmanaged” network devices

32. TCD Self service NAC secondary outcomes Improves job design Requires and supports organisational cultural and structural change Wider technical improvements Difficulties Opportunities

33. Campus Network Accession Authentication and Controlling Student Laptops “Each new wave of technology disrupts existing security measures and introduces new vulnerabilities. In the case of information security, failing to deploy defensive solutions at the right time can leave the enterprise vulnerable. Delays in implementing identity, authentication, and access control products or services can leave the enterprise in catch-up mode in terms of business opportunity.” Gartner, Inc. research (ID Number G00123949; The Future of Enterprise Security)

34. Campus Network Accession - Authentication and Controlling Student Laptops “Got connected to the wireless and wired networks yesterday. Such an improvement over the previous system!” “OK, so have connected to the wired network in my room in college now, all nice and easy to set up compared to before!” “It takes 40 seconds for the restart, and this (I think) has to be done everytime you boot up. Bring back the network clinics I say!!!” Boards.ie October 2006
