I just found Justin Kestelyn's blog entry "Oracle Database 10g R2 Details
" about yesterdays keynote given on the new 10g Release 2. This gives a bit more details than the posts made earlier but not any fine detail on the security aspects. Point 2 about "Information Life Cycle Management" sounds very interesting, with data managed at the row level with highly accessed data being held on high performance media and low accessed data being held on low cost media. This sounds an interesting concept, data being stored according to its importance. In a performance, cost perspective this could save money, i.e. pay only for fast media for a subset of data but from a security perspective it could make an easier target for a hacker, get the important data in one place on the fast media. Is the data already sorted and placed for a hacker?
Interesting reading, let's wait for more details.
