Knowing your network is akin to understanding your military capabilities, strengths, and weaknesses when preparing for an enemy attack.

Success depends on both the currency’s reliable, unique, and falsification-proof security features, and the cashier’s ability to acknowledge these signs. Policy-based network monitoring is practical where acceptable conditions can be documented as policies. For example, a security colleague once discovered a Windows server in the data center making dozens of connections to sites outside his company’s address space, and determined that those sites were botnet controllers. If his company had applied policy monitoring, the server would have been allowed to initiate connections to only a handful of sites.

To ensure the integrity of financial applications, especially those with direct relevance to SOX controls, you must monitor for data integrity within such applications. ).
