Zipline – a VPN security product.

Wednesday, December 16th, 2009

How many of those wordpress, joomla, drupal blogs, web2.0 products of various sort and other websites do you go to that are encrypted using SSL(https)? How many times a day to you enter your credentials, or use cookie based (the ‘remember me’ checkbox type) authentication on websites a day? Do you find yourself in coffee shops, or other public wifi frequently and sometimes wonder who is watching your traffic?

I know I do. Up until now I’ve been using SSH tunnels to get my traffic back home where I know nobody is running a packetsniffer. The trouble with SSH tunnels though is that they’re fickle, and often drop. I wanted a better solution – so I made one.

Making Security Research Relevant

Monday, January 19th, 2009

I’m very very open and transparent about security, technology and what I do. I’ve written documentation so thorough that my clients have ended the contracts stating “we dont need you anymore – with these docs we can do the work ourselves” – in the grander scheme of things thats awesome. I love it when clients learn from me and it makes me feel really good about what I do – especially if it sticks the first time – but it certainly is prohibitive towards me paying my rent.

I’ve been very vocal in the last year about what I do – to the point it manifests itself as talks I give during BarCamp (LA and San Diego), and Refresh San Diego which is held at Qualcomm. Here is my most recent talk

Log Auditing for fun and profit

Tuesday, December 9th, 2008

Again I find myself in a postion where I am in need of full time work. I was able to sustain myself as a full time freelancer for 8 months (not too shabby!), but now it seems the market is drying up and while not for a lack of effort on my part to find sales people or to promote myself by basically bribing people with a 10% commission I’ve not been able to get enough business to sustain myself any longer. I’ll not go into any of the nasty business of clients who decided they didn’t feel like paying me, or clients that had me draw up proposals only to vanish into the ether – because this post is about fun stuff!

All that being said – I like to be clever. I like to use ingenuity to do basically what everyone else does but put a fancy little twist on it. Historically when someone is looking for a job, they will hit some job search sites like monster and dice and then send their resume to people – never knowing if it gets seen with human eyes, or ever gets any attention. Who knows? Does your resume even get read? If it does, how soon? Wouldnt it be nice to see the time correlation between when you sent your resume to someone and when they actually looked at it – or even if they looked at it at all?
