Is your vendor being honest about AI?

Some vendors who claim their products use artificial intelligence or machine learning technology are really using rules-based engines. Here's how to spot the lie.

Why aren't we using SHA-3?

The Secure Hash Algorithm version 3 fixes flaws in the now-standard SHA-2 cipher. Here's how to prepare for a migration to SHA-3 when SHA-2 is inevitably compromised.

How bad are Meltdown and Spectre?

Some people aren't taking hardware vulnerabilities like Meltdown and Spectre seriously. Here's a point-by-point rebuttal to their arguments.

11 sure signs you've been hacked

In today's threatscape, antivirus software provides little piece of mind. In fact, antimalware scanners on the whole are horrifically inaccurate, especially with exploits less than 24 hours old. After all, malicious hackers and malware can change their tactics at will. Swap a few bytes around, and a previously recognized malware program becomes unrecognizable.

Computer security's dubious future

As long-time readers already know, I'm a big fan of Bruce Schneier, CTO and founder of <a href="">BT Counterpane</a>. Besides being a cryptographic and computer security authority, cryptographic algorithm creator, and author of many best-selling books on security, Bruce produces some of the most relevant conversations on computer security. I consider his books, <a href="">Cryptogram newsletter</a>, and <a href="">blog</a> must-reads for anyone in computer security.

Control user installs of software

I've written many times over the years, including as recently as last week, that letting users execute and install their own software will always allow viruses, worms, and Trojans to be successfully installed. Traditionally, I've recommended that users not have admin or root access, that they let system administrators choose what software is allowed and what is blocked. But this recommendation breaks down for several reasons.

Security predictions for 2008

At the beginning of each year I like to talk about what did or didn't happen during the past year, and what to expect in the coming year. Unlike past years, I'll try not to get too emotionally ramped up on all the failures.

How to become an exceptional security manager

I recently listened to a wonderful science program on National Public Radio discussing a book called Better: A Surgeon's Notes on Performance along with its author, Dr. Atul Gawande. The book discusses the reasons why some practitioners excel while others just meet the standards or perform poorly.

Oh so sensible Schneier

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&#8217;s writing gives me moments like that.
