What makes e-mail trustworthy? There are at least two factors at play here: e-mail authentication, as described in a recent article, ensures that outbound e-mail really comes from the purported sending domain.

Brian DeWolfe, senior property manager at Lincoln Property, has a big challenge. The high-end properties he manages in the fast-growing south Florida region require security; indeed, it's one of the biggest line items in the budget, as well as a big draw for potential tenants.

More importantly, what can a business owner, an IT manager, a software developer, a consumer or a risk manager do about stopping ID theft when the problem seems so poorly understood?...

Bob Graham doesn't wait for a threat to become a pandemic. Several years ago, when one of his employees decided to start using a Treo handheld for phone and e-mail, he purchased and installed Symantec anti-virus software on the device -- even though there had never been a documented case of a virus hitting the Treo.

Increasingly clever hackers, thieves and scoundrels are using the Internet, peer-to-peer products, instant messaging and e-mail to wreak havoc, in ways and for purposes never before seen. Their motivation is clear: They want money, and lots of it. Worst of all, they prey on human nature -- and business infrastructure -- to do their dirty work for them...

The past several weeks have seen an onslaught of articles regarding privacy, identity and security. Most of them bemoan the fact that we all have too many passwords, they are difficult and costly to manage, and that "there must be a better way!" Suggestions have ranged from password-reset and password-synchronization software, to biometrics such as finger scans, to third-party "trusted sites" that will act as a broker for all your private information...

President Bush let it be known on April 14 of this year that he does not send e-mail -- not even to his twin daughters -- because he fears his "personal stuff" may be made public.

Imagine you're the CEO of a major bank. Now, imagine paying more and more for security guards, only to find that the risk is increasing, not decreasing, due to threats that can't be countered by security guards.
