When it comes to the dangers of public wifi, many people tend to take one of two extreme approaches. Some don’t give it a thought at all. Some refuse to use it at all. Neither approach is completely practical. So what are the dangers of public wifi, and how can you avoid them?
Here are the dangers and the precautions to take against them.
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. One of the questions he’s planning to ask: How can I know how secure my home computer is? Or, to put his question another way, how safe is my computer from hackers?
I’m going to use this space to elaborate ahead of time on some of the things we are going to talk about. We could talk for an hour on any of the questions he’s going to ask, and he gave me three questions and 25 minutes. This is my workaround.

This, fortunately, may be the easiest question to answer and the easiest step to implement.

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.
My point that I could teach this guy how to do it still stands, though. And I think I could teach Andy how too.
I had a client with a huge list of hostnames that they needed to convert to IP addresses so they could scan them. That’s common. I used to have a Windows batch file to convert a list of hostnames to a list of IP addresses, so I dug it out of my archives. This isn’t like a ping sweep; they knew the machine names but their tool needed IPs.
I used the file to resolve lists of machines so I could load them into a centralized logging or vulnerability management system. This client had the same need and nobody there had a similar tool. So I shared mine with them. And I present it here so I won’t lose it again, and if you need it, you can use it too.
As a security professional, “is DD-WRT safe?” is a question I hear a lot. While there are options that I think are safer, I’m perfectly fine with admitting I use DD-WRT myself. I know a lot of other people like me do as well.
One thing is almost certain: DD-WRT is safer than what shipped on your router from the factory.
I recently saw advice to buy a Cisco RV130W instead of buying an Asus router such as an RT-AC66U and souping it up with Asuswrt-Merlin. I can see both sides of the argument but in the end I favor the Asus solution when I consider Asuswrt-Merlin vs Cisco. Here’s why.
Now, if you’re arguing business vs personal use, there’s no contest. In a business setting, buy the Cisco.
Whether you’ve gotten a tech support scam phone call or not, it can be helpful to know how to clean viruses off your computer for free. And yes, I do mean free.
A lot of people get ripped off due to virus scares and it makes me mad. I’m a computer security professional. I advise large companies on computer security for a living. Today I’ll take a few minutes to advise you.
