Over the last ten years, our world has become interconnected in ways not previously imaginable. Today, for instance, people in Spain, the US, and Brazil can find out simultaneously that soccer-star David Beckham has switched teams. Small companies can now affordably be spread across the globe, and big companies can now have inter-office collaboration on a daily basis. But all of that interconnectedness relies in large part on our ability to protect the networks that create those connections. Unfortunately, and despite the best efforts of network security managers, the last five years have seen hackers and criminals become increasingly effective at compromising these networks, as they have quickly developed new and ever more malicious threats to network security.

These newly created threats have been so successful in large part because most employees of companies, despite being regular internet users themselves, have no idea how these new network security attacks work, and have only a vague conception that these new threats even exist. This article will introduce you to ten of the biggest and most dangerous threats to network security, in an effort to make everyone more aware of the security problems facing networks today.
