in a World Without Perimeters

   During this session, Dave McGinnis, Director of Managed Security
Services Architecture at ISS will examine the strategies and
architectures for data center security in a world where the
"perimeter" is melting away. The erosion of the traditional enterprise
perimeter, due to increased worker mobility and connectivity, has made
it necessary to devise new strategies to protect data and systems.
McGinnis will discuss the benefits of delivering preemptive, layered
protection via the data center.

   Wednesday, September 20, 2:15 - 3:15 pm ET - Emerging Trends in
Information Security

   Information security is an ever-changing concept. Both the threats
that are posed to organizations and the solutions used to protect
against those threats are constantly evolving. Joshua Corman, Host
Protection Architect at ISS, will join this panel to discuss emerging
trends in information security, including the need to implement
multi-layered solutions in order to effectively address the full range
of online threats.
