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
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.

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.”

Future of Enterprise Security)

“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!!!”
