Someone asked me the other day how does MAC address filtering help to secure a wireless network? If you’re in a position where it would help, I argue there are other things you need to do. But I’ll explain how it works, then what I’d rather you do instead.
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.
Skycure helps keep your Android devices secure. A coworker who came up through the mobile space recommended I check out Skycure. I liked it right away. This is my Skycure review for Android.
Vulnerability management and patch management are close relatives. In most companies, think of them as siblings who hate each other. That’s usually how it plays out. It doesn’t always have to be that way, but it takes some thought and strategy from both sides. Here are some ideas for patch management strategy.
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.
The best Pfsense hardware is rather subjective. I think the ideal Pfsense box should deliver solid performance while being affordable.
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?
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.
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: “What can I do to improve the security of my digital information?”
This, fortunately, may be the easiest question to answer and the easiest step to implement.
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.
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.
