According to cloud security solutions provider Commtouch, inboxes everywhere have seen a 30% drop in spam this December. An earlier 18% drop in October is associated with the closure of spam organization Spamit in September – spam level for Q4 overall was 83%, down from 88% in Q3 2010.

Spam has always been a fairly big issue, which means a company working to decrease it is always a good sign as well as an indication of the growing significance of security for the cloud.

“The nature of the spam attacks has also clearly changed.  The pre-October graph shows large fluctuations in the amounts of spam sent.  In Q4 2010 there were generally lower fluctuations – aside from two large outbreaks in mid-October and mid-December.

As before, we remain cautious about the long-term implications.  Spam levels have decreased in the past only to return to even higher levels within short periods.  Don’t pack away your Anti-Spam just yet. “

As more and more businesses adopt the cloud, ensuring the cloud’s security will gain more significance and increased attention. A recent example supporting this analysis fairly well is the string of data leakages lately involving Honda, Mozilla, iPhone apps and more, which we discussed here. Another is the sophisticated Android Trojan Geinimi detected last week, to which cloud Smartphone security firm Lookout Mobile Security responded recently.
