PCI: Best Practices For Point Of Sale Security

In the field of security, the saying "a chain is only as strong as its weakest link" is especially true. Criminals are known to migrate along the path of least resistance to the softest, or least risky, target. Any security system is only as strong as its weakest link.

When it comes to the security of the millions of point of sale (POS) devices in operation today, it is essential to define the operational lifecycle of these terminals. Defining the lifecycle helps to highlight the points at which criminals can attack POS devices.

Once the POS lifecycle has been described and defined, security best practices can be directed at all operational phases so that the whole "chain" is strong and secure.
