Developing security strategies that can protect all parts of a complicated network while having a limited effect on ease of use and performance is one of the most important and difficult tasks related to network design.

Security design is challenged by the complexity and porous nature of modern networks that include public servers for electronic commerce, extranet connections for business partners, and remote-access services for users reaching the network from home, customer sites, hotel rooms, Internet cafes, and so on.

According to the most recent Verizon Data Breach Investigations Report [PDF], an estimated "285 million records were compromised in 2008." And 74 percent of those incidents were from outside sources.

The chapter presents a modular approach to security design that will let you apply layered solutions that protect a network in many ways.

The final sections describe methods for securing the components of a typical enterprise network that are most at risk, including Internet connections, remote-access networks, network and user services, and wireless networks.

Individuals and corporations benefit from the elastic deployment of services in the cloud, available at all times from any device, but these dramatic changes in the business services industry exacerbate the risks in protecting data and the entities using it (individuals, businesses, governments, and so on).

Security policies and architectures require sound principles and a lifecycle approach, including whether the data is in the server farm, mobile on the employee’s laptop, or stored in the cloud.

Data security should be an important area of concern for every small-business owner.
