status of introducing security mechanisms in Debian

[mircan@poczta.onet.pl]

Hi,
I'm writing with reference to security test performed by MWR Labs last
year. To avoid writing too much I'll just give links to the articles
describing the tests:
http://labs.mwrinfosecurity.com/notices/security_mechanisms_in_linux_environment__part_1___userspace_memory_protection/
http://labs.mwrinfosecurity.com/notices/assessing_the_tux_strength_part_2_into_the_kernel/
As stated in the articles in Debian Lenny there were very little of
available security mechanisms of the Linux environment included. I
just wanted to know what is the status of this in Squeeze and also
rise a release goal for Wheezy to enable some pro-active security
mechanisms mentioned in the articles. For example, I guess enabling
PIE in iceweasel, other web browsers and network daemons is worth
taking into consideration. I know my point is extremely general, I
just hope to start a discussion about this topic.
Thanks,
Marcin
