Using Android KitKat with pfSense IPsec VPN

Getting your Android KitKat device to work with pfSense IPsec VPN server is a finicky process and the settings on both sides need to be exact. Android only supports a small subset of common encryption schemes and this article will show you what settings to use.

Samsung Galaxy S4 (SPH-L720) “FAIL (auth)” and “SW REV CHECK F...

These errors indicate that the phone cannot use the ROM provided (via Samsung’s ODIN loader) because the ROM is either not legitimate or is a version prior to the one currently installed. Basically, if you’ve flashed a ROM that is Android 4.4.2 (KitKat), you will not be able to revert back to an earlier version (such as Android 4.2.2).

Protecting Apache2 Against Slowloris DoS

Slowloris is a tool to DoS an HTTP(S) web server without performing a traditional high-bandwidth “flood” approach. I’ll give you some background on how Slowloris is so effective, even today, and how to protect your Apache servers from this type of attack.

The FIDO Alliance’s “Second Factor Experience” In A Nutshell

The FIDO Alliance is a conglomerate of top technology corporations (Microsoft, Google, Oberthur, NXP, Paypal, etc…) aiming to create standardized enhanced authentication with specific goals of “Passwordless Authentication” (UAF) and “Second Factor Authentication” (U2F). Essentially, they want to be able to framework how companies provide secure access to their web resources as well as how users prove their identity to the companies. Here’s my take on the effort.

Authentication solutions comparison

There’s a lot of debate in the information security industry about what the next-gen solution will be for authenticating users into services (websites, applications, etc…). I’ve collected a list of suggested authentication solutions (both hardware and software mechanisms) and will try to shed some light on their pros and cons.

LogMeIn Rescue SAML 2.0 Authentication Tips

I’ve dealt with a lot of integration projects involving Single Sign-On using SAML2.0 but LogMeIn Rescue’s process for achieving this threw me for a loop initially. I’d like to share a little insight to hopefully help others achieve SSO using LMI Rescue with minimal pain.

HowTo: Fix VMware error “No more space for virtual disk”

Snapshots will grow over time as they have to maintain a delta file to track what changes have happened to the VM since the snapshot was taken. These will eat up space if left for long periods of time and can eventually consume all of the avaiable free space (thus causing this error).

HowTo: Install Android KitKat 4.4.2 on Samsung Galaxy S4 (Sprint)

This tutorial walks you through installing Android 4.4.2 Kit Kat [OmniROM] on your Samsung Galaxy S4 for Sprint networks.

Dell Insprion 1545 upgrades on the cheap

There are 3 areas I’d like to cover as upgrades that either improve performance or just ones that I’ve done myself that I’d like to share. There are a lot of question marks about which CPUs or Wireless adapters are compatible. I will tell you what I know for fact will work and what the results of those upgrades were.

Dell Inspiron 1545 Wireless Adapter Upgrade (802.11agn 5 GHz WiFi + Bluetooth 4....

After recently moving to a new house, I decided to take some time to carefully plan out my home network. One of the sore points of living in a city is that you have neighbors; lots of neighbors with WiFi APs polluting the 2.4 GHz band. I wanted to avoid this at all costs and decided to enable the 5 GHz radio on my Netgear WNDR3700 v4 running DD-WRT build 22118 (highly capable hardware and firmware combination for a home AP).

Great food, cool cats, and more…

I’d like to share a blog that my friend, Caitlin, runs. You’ll be sure to find articles with insight into modern internet users, food pictures/recipes (my favorite), as well as the internet’s current focus, pictures of cats. I love seeing people I know put hard work into running a website/blog and love to be able to say “hey, check out this cool site my friend built!”. http://journeyintothismindofmine.blogspot.com/

Convert Windows Public Certificate (.cer) to OpenSSH Public Key

If you have a PKI certificate in your Windows PC that you would like to use to log in to your OpenSSH-enabled Linux server, it can be a pain to figure out how to extract the public key from this file and convert it into a format OpenSSH can understand.

What’s the Future of Passwords? A Conversation

As professionals in the authentication space, we stay up to date with technology providers and their solutions. For this post I have invited Abby Porter, Director of Product Management at Delfigo Security to discuss whether it’s time to get rid of passwords all together, and the challenges associated with doing so.

Dyn Geek Summer Camp 2013

The Dyn Geek Summer Camp 2013 conference in Manchester, NH was held yesterday and today. It was probably the best conference I’ve been to this year and, best of all, it was a 5 minute walk from work. Great speakers, great entertainment, a great facility, and great food! This was Dyn’s first year hosting this conference and I hope they continue this new tradition as it was a blast and I felt like I’m walking away with a little more insight into what’s to come in the realm of technology. Here’s some photos and videos!

Testing a Hard Drive for Errors with Seagate SeaTools

If you believe your computer may be experiencing hard drive failure or if you would just like to make sure the hard drive you use to store all of your data currently is in good shape, you should test your hard drive for errors! There are many free utilities out there that perform some basic tests or read the S.M.A.R.T. data, but it’s hard to beat a utility made by one of the largest hard drive manufacturers, Seagate (I mean, c’mon, who knows hard drives better than those that create them).

Profiting From Complexity; A Recipe For Disaster

There are two types of software companies; those that profit from improving the user’s experience and those that profit from the user’s lack of technical knowledge. When designing software, it’s easy to take the lazy route and only create the bare minimum required to make a process work (requiring manual editing of configuration files, setting permissions, offloading any other unfinished task to the end-user). Even if the software being created does, in the end, accomplish a complex task, the result will be an alienated customer with dwindling chance of any purchase in the future.
