Security engineers spend countless hours tightening the perimeter of their network, purchasing appliances, virus protection and sandbox services to combat the latest
zero-day warnings. Then the one day they think they have it all under control, the unthinkable happens – a breach in the network. The team manages to gain control, closes the gap and remediates the issues. When the disaster recovery plan has been completed and the summary report is due, the source of the invasion was something that was simply overlooked. All the planning, hardware, BMP and employee training was subverted by an issue that deserves the hardest face-palm.
