Common security attacks and countermeasures

As a security professional, I talk to a lot of people about common security attacks and countermeasures. I’m not always certain the people I’m talking to know what these things mean. I am almost certain they aren’t willing to ask.

I know it’s more complicated than it was when I took my Security+ exam a decade ago. The stakes are much higher now. The attacks I had to identify caused inconvenience, but someone conducting a successful smurf attack on your printer won’t get you in the headlines. Today’s attacks will.

What to look for in a USB flash drive

What to look for in a USB flash drive

USB flash drives are pretty much a necessity these days. They’re far more convenient for moving files around than optical discs, and they make good backup devices. But not all USB flash drives are created equal. Here’s what to look for in a USB flash drive.

Here’s a tip: I don’t just use USB flash drives for transporting data and backups. I like to keep a modest-sized USB flash drive plugged into my router, turning it into a small NAS. It gives me a convenient, reliable place to back up data from any of my computers.

How easily can someone hack my home computer and steal personal information?

On Monday, March 13 at approximately 10:30 AM CST, I will be appearing on KFUO Radio’s Faith and Family program to discuss home computer security with host Andy Bates. Here’s the scariest question he’s planning to ask: How easily can someone hack my home computer and steal personal information?

Someone asked me that question at work once, except it was about a work computer. I whipped out a copy of a book about Metasploit, flipped to page 137, and started reading. My point was that I could teach this guy how. He didn’t take it well, so I don’t recommend doing that.

Another member of my team sent us a warning that a big DDoS attack was happening, and not to count on being able to issue very many quotes today. So what, exactly, is a DDoS attack and how do DDoS attacks work?

I suppose there’s another question to ask too: What can you do to avoid being part of the problem? We’ll save that for the end.
