Managing outbound email security threats

SCmagazine

When the subject of email security is mentioned, the first thought that comes to mind is "spam" or more appropriately "anti-spam."

Historically, messaging security solutions focused on protecting corporate networks from outside annoyances like spam, as well as messaging-based threats, such as viruses, phishing attempts, directory harvest attacks and other such external threats. This mentality of "keeping the bad stuff out" has allowed internally driven threats to go virtually unchecked. However, we always seem to think that firewalls and antivirus are all we need to "keep the good stuff in."

Vendors across the mail security space tout their effectiveness at spam detection and speed-to-market with anti-virus signatures. Both of these approaches are both completely reactive, as well as focused on the wrong direction of critical data flow. We must recognize that the scope of threats to email security includes the inside menace.
