Many of today's computer passwords are stored and transmitted in a cryptographic hashed form. A strong password hash algorithm ensures that if the password hash is obtained by unauthorized parties that it is non-trivial to convert the hash back to the original plain text password (assuming the password is not trivial to guess at in the first place).

I can't believe my eyes. Eudora WorldMail Mail Management Server has an open exploit hole and Qualcomm says they have no plans to patch.
Microsoft has a cadre of antimalware tools. Most are free, but some current and forthcoming options are commercial. Any marketplace entry by the Redmond-based company becomes an immediate formidable foe lessening competitor profits.
I teach computer security for a living. Last week, a class of mine asked which vendor had the best security. I responded that they all are pretty bad. If you aren't using <a href="http://www.openbsd.org/" target="_blank">OpenBSD</a> or software by <a href="http://cr.yp.to/software.html" target="_blank">D.J. Bernstein</a>, then every other product in the world is pretty bad in comparison.
I first heard that the antivirus scanner was dead in December 1989. Experts had postulated that the increase in the number of different computer viruses, which at the time numbered almost 200, would quickly outpace the ability of antivirus scanners to keep up.
Here's a sobering prediction: One-third of all adults in the United States will have their personal identity information compromised or lost this year by a company that electronically stores the data, according to figures supported by the Privacy Rights Clearinghouse. Whether or not that number is perfectly accurate, the list of publicly known data breaches is staggering nonetheless.
Most security solutions are a trade-off of ease-of-use versus security. As computer security measures grow in importance, previously uninterrupted legitimate processes get reined in or stopped altogether -- like my recommendation of not allowing non-admin users to install software without management approval. As companies grow more valuable, they are willing to accept higher levels of default security as measured against legitimate needs.
I was recently contacted by the company that manages my stock to open up a new Web site log-on account. During new account creation, it asked me to input a secure password. So, I put in my normal password that is 21 characters long followed by 10 characters that are unique per Web site, but only uses lowercase letters. The length of the base password prevents basic password cracking and guessing, while the additional characters make the overall password (or pass phrase) unique so that no two resources ever have the same password.
As expected, I caught a lot of flak for last week's column suggesting that one of the better, real security solutions an administrator could implement is to prevent unauthorised programs from executing on business-owned computers.
Last week, the curmudgeon in me had a bad day. After reading about new exploit after new exploit while people keep recommending the same old security solutions, I lost it.
I had yet another computer journalist call me to ask if Vendor X's security solution was THE security product to solve all our security problems. I get a call or e-mail like this about once every two weeks. Usually they've read the vendor's own PR, another newspaper article, or even my own column touting a particular product.
SSL-evading trojans bypass the secure and authenticated tunnel mechanisms that are the safety backbone of today's Internet banking and financial institutions. As with any trojan, this type can do anything allowed by the user's security permissions.
Have you ever had one of those moments where something you knew to be certain was turned upside down and you learned you had been wrong ... for years? A lot of Bruce Schneier's writing gives me moments like that.
A secure connection between browser and back end underlies Internet commerce. But what if it's already compromised?
During my nearly two-decade computer security career, I've always been amazed by how many security myths are propagated as fact by readers, instructors, leaders, and writers.
