As an undercover agent with the US Drug Enforcement Administration and the Food and Drug Administration, Aaron Graham saw firsthand how counterfeit drugs can slip into the pharmaceutical supply chain. Graham, now VP and chief security officer for Purdue Pharma, once posed as the manager of an "institutional pharmacy" selling drugs at a discount to secondary wholesalers who were then supposed to sell them to nursing homes. Soon after he began, his phone started ringing. Dozens of smaller pharmaceutical wholesale companies were calling, desperate to buy his drugs. These secondary or "grey market" wholesalers scour the country and the world for low-price drugs they can sell back to major wholesalers for a profit.

Even as his dinner bursts into flames, he's unwilling to let go of his phone for fear he'll miss a chance to speak with the next available agent. He tries to put out his flaming dinner with a broom, only to have the broom catch fire.

A year has passed, but Aug. 29, 2005, remains a fresh memory for Mississippi Power CIO Aline Ward: As Hurricane Katrina slammed the Gulf Coast, Ward scrambled to keep communication lines open from a command center in the utility's Gulfport plant. Because this storm center was located several miles inland, Ward thought equipment would be safe from flooding. "We were on the second floor, but soon the water started to rise and come inside the building," recalls Ward. Working in the dark, Ward and her IT colleagues piled sandbags against the door and bailed water from the room to keep radio communications equipment up and running.
