  • Internet (or intranet) accessible

  • A massively scalable, user-configurable pool of elastic computing
    resources (such as network
    bandwidth, compute power, memory, etc.)

  • Multitenancy (one large software instance shared by many customer
    accounts)

  • A broad authentication scheme

  • Subscription or usage-based payment

  • Self-service

  • Location indepedent

All of these traits offer new challenges to the computer security
professional, but accessibility, multitenancy, broad authentication, and lack of
location specificity are the four items responsible for the biggest technology
shift and demand for new security solutions.
