Open source identity: Bitcoin technical lead Gavin Andresen

Originally from Melbourne, Australia but now living in the US, Gavin Andresen is the technical lead of the Bitcoin virtual currency system. Started by Satoshi Nakamoto in 2009, Bitcoin is a digital currency system consisting of an open source client and P2P network. The aim of the Bitcoin project is a decentralised, secure peer-to-peer currency system that does not rely on banks or central transaction processing authorities. To generate “Bitcoins” people on the network use a cross-platform, open source client developed in C++. In addition to the open source aspect of Bitcoin, there is now an emerging market in services around the cryptocurrency such as exchange portals and virtual clearing houses. Previously, the Open Source Identity series has featured interviews with Ruby on Rails creator David Heinemeier Hansson, Linux’s Linus Torvalds, Jan Schneider of Horde, Mark Spencer of Asterisk fame, Spine CMS creator Hendrick van Belleghem, Free Telephony Project founder David Rowe, and PulseAudio creator Lennart Poettering. This time we talk to Gavin Andresen about the new, decentralised approach to money – Bitcoin.

Estonia readies for the next cyberattack

More than anyone else, Jaak Aaviksoo has first-hand knowledge of what a cyberwar might feel like. In April 2007, Estonia's banking, media and government presence online was disrupted by several waves of distributed denial of service attacks that knocked services offline. The country is heavily wired -- 90 percent of all financial transactions are conducted over the Internet and 70 percent of the population files their tax returns electronically -- so the incident was widely felt by the country's 1.3 million citizens.

Five Ways To Survive a Data Breach Investigation

Security experts say it all the time: If a company thinks it has suffered a data security breach, the key to getting at the truth unscathed is to have a response plan in place for what needs to be done and who needs to be in charge of certain tasks. And, as SANS Institute instructor Lenny Zeltser advised in CSOonline's recent How to Respond to an Unexpected IT Security Incident article, "ask lots and lots of questions" before making rash decisions.

McAfee looks to security in virtual environments

McAfee is hunkering down to integrate the security technologies it has bought over the past several months into its varied line of security software and appliances. Two trends in the company's activities are developing parallel products for deployment as software on endpoints and as network-based appliances. This week, for instance, the company is announcing that NAC software can be installed on its IntruShield IPS appliance to give customers the option of enforcing NAC policies in the network, not just on the endpoint. The company is bringing management of these platforms under control of its ePolicy Orchestrator (ePO) in an effort to centralize control of network security. Network World Senior Editor Tim Greene spoke with McAfee CEO Dave DeWalt about these efforts as well as other issues facing the company.
