roundup Securing mobile devices is still a hot topic, but the spotlight is now being cast on the security of communication tools--old or new--used in the workplace.

As technologies such as VoIP (voice over Internet Protocol) and RFID (radio frequency identification), become more mainstream, the impact of vulnerabilities in these technologies is naturally more strongly felt.

Instant messaging (IM), which use in the enterprise is on the rise, has emerged as an area where security deserves some attention. According to Gartner, organizations that are unable to adequately control the way IM is used will be much more vulnerable to security attacks.

Here's a look at what went on in the communications security space in recent months.
