So, long story short I've been busy working on a new service for my business.  I've gotten it close enough to the end now I'm happy to talk about it, and thought a blog post about one of the features would be a nice way to start things off. I've been learning a lot of Python over the past week...

For years upon years now people have been using passwords to authenticate themselves. However, the time has come for there to be a new contender. While I do not have the magic answer as to how to solve this issue, I do have my reasons for researching this topic. Take for example password...

Long time no post, hah.  But this post is about something involving SSH and the glorious ssh-keygen (keypair generator).  This won't be beneficial to a lot of people, but for me it has posed to be quite a wonderful asset to my scripts. Idea Behind This Why would anyone want...

I started writing this article late last week or earlier this week, but some unknown issue happened (gotta love driver issues).  The point of this article is to cover the benefits and costs of both passive and restrictive firewalls.  When I first got into I.T. security I always thought...

Its 12:40 AM here as I'm typing this, on a Saturday night, and what better thing to do than to discuss some security? :)  I'm all for healthy competitions (heck, I even partake in some wargames for the fun of it).  But this is one that could really benefit you.  Here's the main points: the GCHQ...

BrowserID, security

Browsing through various articles, there was one on Linux.com that caught my eye. It talked about Mozilla's new "security feature" that is meant to, what seems like, take over the (rather limited) market that OpenID has created.

For the better part of two years now, I've been looking at various flavors of Linux, trying to see which one(s) are right for my needs.  For servers, I stopped after finding Arch Linux, as it gave me the freedom to use as much of my resources as possible, without the overhead of a GUI and such....
