One of the most difficult challenges in managing networks is their inherent vulnerability to human error. No matter how robust an organization’s security policies or how dedicated its IT staff, a silly oversight by one or more employees can render many precautions meaningless.
A startling example of just how quickly and thoughtlessly network security can be compromised occurred recently when the Wi-Fi network name and password for the security center at the World Cup in Brazil were accidentally posted online.
A newspaper photo of Luiz Cravo Dorea, head of International cooperation for the Brazilian Federal Police, was taken inside the center, run by Israeli security firm Risco, in front of a bank of computer screens, one of which showcased the sensitive information. Soon after the photo was posted, it was re-tweeted repeatedly for the entire world to see. Once the newspaper was made aware of the photo it was taken down and presumably, the network name and password were changed. But it is impossible to know if any intrusions occurred in the interim.
While businesses should make every effort to avoid these kinds of blunders, the unfortunate fact is that they do sometimes happen despite network engineers’ best efforts. When these mistakes occur, it’s imperative that businesses have network monitoring and security solutions in place that keep a simple oversight from turning into a total disaster.
Best-in-class network forensic appliances can be used to monitor compliance with security policies and to intercept and analyze unauthorized attempts to access a network. These products can automatically respond to security threats in a variety of ways, meaning that even if a password is leaked, intruders can’t freely enter a system and steal or compromise data.
