Following the release of our report, ‘The Myth of Open Source License Proliferation’ and during research for it, we heard and sensed a feeling that open source software licenses had evolved to become a generally well-accepted piece of the the enterprise IT and IP market.

I track security updates for the following vendors: Apple, Cisco, FreeBSD, Microsoft, Red Hat, and Sun Microsystems. I chose these vendors based on my own needs for the networks and systems I manage. I've also found that updates from these vendors tend to catch the major updates necessary for common software applications. If you have other vendors you would like me to provide updates for, send me a message.

If you have an interest in information security from both a technical and managerial level, check out Principles of Information Security. It does an excellent job of presenting material for both audiences.

As well as contributing to the CAOS research practice here at The 451 Group I am also part of the information management team, with a focus on databases, data caching, CEP, and - from the start of this year - data warehousing.

I’ve covered data warehousing before but taking a fresh look at this space in recent months it’s been fascinating to see the variety of technologies and strategies that vendors are applying to the data warehousing problem.
