Sean has let me know that he has just started a new Oracle blog called Oracle and Open Source. I took a look last night and whilst there is nothing specifically about Oracle security there yet it is still an interesting blog for me as I am always interested in open source tools especially related to Oracle. There are a number of Oracle security tools that are free and I am sure there will be more. Open source is a great way to develop new tools for Oracle and it will find particular uses in security.
I will be keeping an eye on Seans blog and needless to say, if he talks specifically about security and Oracle I will let you know here. Take a look at his new blog.
