2. SMS is a secure communications tool.
In fact, SMS, or Short Message Service, is a key vector for the distribution of mobile malware. While modern cellular protocols encrypt data sent over the air, the carriers themselves provide no guarantees of security. Opportunities for compromise on the wired part of the network, after the over-the-air encryption is removed, are well known.
For this reason, be cautious about any SMS, instant messaging or similar service. Because these services don’t provide tracking or auditing, management has no visibility into precisely what information might have been exposed.
While instant messaging is undeniably convenient, organizations seeking security should only deploy this capability as part of an enterprisewide unified communications strategy.
