People should be careful about working themselves into too much of frenzy over the so-called Heartbleed bug. One good sign is that the encryption software flaw has been out there for some two years according to an excited media. No one seems to have noticed. This does not mean that we should not be concerned, but it does mean that nothing has happened in areas that really matter to us. Like banking. There is no word from any of the big banks that their systems have been compromised. Canada Revenue Agency said Wednesday it has temporarily cut off public access to its electronic services over this flaw. This has been done as a precaution. And again, the bug is something that has been out there for a while. If you haven’t noticed anything — lost money, phony bills, nasty e-mail — whatever — it may not be a concern to you.
