When dealing with something as invaluable as customer data, think about creating a unified strategy that incorporates the network, people, and tools. Security is like a chain: It is only as strong as its weakest link. So, do not be tempted by a piecemeal approach. Instead, create a single, integrated strategy that focuses on return on value rather than return on investment.

It helps to work with trusted vendors that can provide end-to-end security, from the network foundation to the most remote laptop. You should also find the right balance between security and usability. The more secure your network is, the more difficult it can be to use.
