Re: Debians security features: Which are active?

Thank you for all your replies.
I understand that the user is important for security, but it's a difference whether you start from scratch or you can work with somethink prebuilt. So, could you tell me, which of the following securit features are enabled in Debian by default and which I have to activate manually:

Stack Protector
Heap Protector
Pointer Obfuscation
Stack ASLR
Libs/mmap ASLR
brk ASLR
Built as PIE
Built with Fortify Source
Built with RELRO
Built with BIND_NOW
Non-Executable Memory
/proc/$pid/maps protection
Symlink restrictions
Hardlink restrictions
ptrace scope
0-address protection
/dev/mem protection
/dev/kmem disabled
Block module loading
Read-only data sections
Stack protector
Module RO/NX
Kernel Address Display Restriction
Blacklist Rare Protocols
Syscall Filtering
Block kexec

For further information go to https://wiki.ubuntu.com/Security/Features

Thank you very much!

Betreff: Debians security features in comparison to Ubuntu

Hello there,
I'm a new user of the great Debian distro for my Desktop. But when I talked to a friend and I told him, that I'm using Debian (Wheezy) for my desktop computer, he told me that I shoudn't use it because it is not secure. He told me to use Ubuntu instead. He explained that with the fact, that Ubuntu has more security features enabled than Debian (also more compiler flags for security) in a fresh install. He gave me a link to the following site:

So, I'm very happy with Debian but because my friend seems to be an expert for Linux, I don't know if I can use Debian. Can you tell me which of the security features promoted by Ubuntu are also enabled in Debian?

Thank you very much!
