Anti-spam filtering can no longer be considered a reliable tool for protecting your e-mail infrastructure and/or your users from the many threats that use e-mail as their primary insertion vector. Smart IT professionals have come to realize it is impossible to determine intent from content. As we move into the 2nd decade of the 21st century, security on the Internet in general, and for e-mail specifically, must become personalized. We can no longer afford to count on the ability, or lack thereof, of a filter to guess what is good/safe and what is not. The next era for e-mail security will be ruled by systems that provide and promote Sender Address Verification and Authentication.
Domain forgery must be stopped; and we have the tools at our disposal to make this happen. The time has come, once and for all, for IT professionals to embrace and deploy BOTH Sender Policy Framework (SPF — www.openspf.org) and Domain Keys Identified Mail (DKIM — www.dkim.org).
While its true that “cloud computing” is well on its way to becoming the “2009 Buzzword of the Year,” the time has come for IT professionals to seriously consider moving the major security components of their e-mail infrastructure onto their own private islands within the greater computing cloud. Processes like anti-spam, anti-virus, anti-threat, compliance, data leakage prevention, and managed file transfer can be addressed more effectively and more efficiently before any data ever reaches the threshold of your private network.
In a difficult economy like we have today, e-mail is a more important tool than ever. E-mail is the ultimate asynchronous communication tool and is critical as a cost effective means for individuals to communicate over long (and short) distances. In both the medium and long terms, IT professionals must continue to strengthen their e-mail infrastructures. Now is not the time for cost cutting with respect to e-mail.
Early this month Google announced their newest project: Wave (wave.google.com/help/wave/about.html). While it is too early to tell if this new project/protocol will have any real impact in the near term, looking forward 18 – 36 months, this is something upon which IT professionals should keep close watch. If Google is even remotely successfully, and who would bet against Google, this new and open protocol has the potential to completely change the way people communicate on the Internet through the merging of e-mail, instant messaging (IM), and real-time collaboration.
