Every time we access an Internet resource (web, mail, IRC, etc…) our ADSL modem or router is connected “directly”: all packets transmitted by our computer are addressed via routers and switches across the net to their final destination.
Every time our packets pass through a network device, someone could read, analyze, intercept and hijack our communications.
In order to avoid this and protect our information, our identity and our connections we can use the widely downloaded software FreeNet.
Using Freenet we can access anonymous resources across the internet, using a decentralized encrypted network or we can create our private network between friends to chat, share information and messages.
OpenVPN accelerator on AlixBoard using PfSense
I have setup an Open Source firewall/VPN terminator using an excellent AlixBoard 2D.13 and PfSense.
Actually PfSense release 2.0 has just been released, but I’ll upgrade as soon as possible and this post is related to PfSense 1.2.3
I think that AlixBoard 2D.13 + PfSense setup is a really good solution to have an OpenSource UTM box for small networks (SOHO): stable, cheap and open-source! In this post I will not explain how to setup PfSense on AlixBoard (you can find lots of great HowTo’s on Google) but how to improve your OpenVPN performance using the AlixBoard embedded cryptographic accelerator.
This post is based on great articles and site available on PfSense Web Site and Gorlani.com
How to synchronize your data in the cloud securely
Today we can easily access lots of free services “in the cloud” for documents sharing, photo publishing and filessynchronization. Most user will be happy to have same pics or documents available on different devices (think about a “classic” scenario with a single user accessing data from Home Desktop, company laptop and personal iPAD) forfree but we must think securely when we move or copy personal information across the internet.Dropboxcompromission is a clear example about “cloud security”. In this post I will try to explain how the data can be lost and how we can improve data protection using Free Software over different platforms.
