False

The popularity of services such as Facebook, LinkedIn, and Twitter has made the loss of information or loss of control of that information through social media less of a concern.

False

Whenever possible, security practitioners work to encourage people to use their social network for both their professional activities and their personal activities.

False

A buffer overflow can result in data being corrupted or overwritten.
