Dave Farquhar — Thu, 07 Jan 2016 12:00:33 +0000

The other question that came out of my recommended DD-WRT settings was why not filter MAC addresses. I hate to be flip, but MAC address filtering doesn’t help, so why bother? The reason is because your MAC addresses are broadcast as

Dave Farquhar — Thu, 24 Dec 2015 12:00:34 +0000

I’ve been asked a few times now for my recommended DD-WRT settings, or at least my good-enough settings. I think that’s a great idea, so I’ll walk through how I configure a DD-WRT router. Follow these steps and I can

My mother in law didn’t have wifi set up, but she picked up a smart TV this year, so she asked me if I could help her with it. So I picked up a D-Link DIR-615 on sale, brought it

Things I wish everyone knew about home computer security

Dave Farquhar — Thu, 17 May 2012 02:22:26 +0000

I’m a security professional by trade, with two certifications. I’m not responsible for defending your computer networks, but I want your networks to be secure. There’s a really simple reason for that. If your computer and your network is secure,

Doc, what security settings are you using on your network?

Dave Farquhar — Tue, 15 May 2012 12:23:42 +0000

A reader who will remain anonymous (he can out himself if he wishes) sent me an interesting observation. He was in his doctor’s office last week, and out of curiosity, he ran a wifi scanner on his phone just to

Securing wi-fi isn’t about price gouging

Dave Farquhar — Wed, 28 Mar 2012 12:22:31 +0000

The so-called wi-fi golden era is over, and apparently being glad about it makes me an absolutist. But John C. Dvorak is wrong. This isn’t about making people pay for Internet access. It’s pure security. Toilets and drinking fountains are

How to make a DMZ with two routers

Dave Farquhar — Mon, 21 Nov 2011 11:35:39 +0000

I’ve alluded in the past to why it’s a good idea to make a DMZ with two routers, but I’ve never gone into depth about how and necessarily why to do it. If your ISP gave you a combination modem/switch/access point/router

Dave Farquhar — Sat, 12 Nov 2011 12:03:02 +0000

For the first time ever, I actually have a wireless router that can cover my whole house. I’ve been interested in wireless security for a long time, but haven’t actually had to do much with it because I wasn’t running

How to secure your wi-fi router

Dave Farquhar — Sun, 10 Oct 2010 20:42:53 +0000

It’s not enough to know what to look for in a router. I wanted to get some solid advice on wi-fi network security. Who better to give that advice than someone who built an airplane that hacks wi-fi? So I
