but your knowledge is very little it seems
If your ONLY defense left is SELinux then one is quite naked to the world with only one last fig leaft to protect you :)
uneducated and wrong guess - SELinux is not your only defense - it is the last resort by design
Althought I think you answered this line too fast, taking that line out of context, given the explanation I gave in the next paragraph.
no my daily job is security based on knowledge and not on uneducated guesses
> Attackers should first have to breach the firewall and then obtain some sort of user access *what* has a firewall to do with a potential buffer overlow in running code resulting in execute inujected code on your system - that's what SElinux is about may i suggest to learn basics about the different layers of a operating system before read random completly unrelated articles and speard FUD based on them without understan dwhat they are talking about?Again, I think I am not explaining properly my thoughts. In this paragraph I am talking of the total security of the system and the different layers an attacker would have to peel before pawining the system, not of SELinux alone.
again: SElinux is the *last resort*
> then trick the system to scalate it to a root access before SELinux comes into play may i suggest to learn how SElinux works it is supposed to prevent exactly thisAnd that is my point exactly. If as the article has said, NSA is spending millions to compromise security systems, how sure are we that there isn't something in the code that allows them to bypass the protection that SELinux promises to confer? Before the article, I'd agree with you, "FUDmongering". After it, I wonder. BTW, thanks for the correction, I was forgetting once an attacker gets root, you are pawned. I was wondering at the wrong level :)
anything not proven by facts is FUD

But after reading it, I just wonder if there is any Achilles heel in the armor
if you only would understand how stupid your whole argumentation is
* SLinux is opensource * it is part of the kernel * it is reviewed by a lot of people outside the USA * if you do not trust these people you must not trust the rest of the kernel
well, and in this case use Windows or OSX but wait, both are closed source and US companies so who do you trust more - USA closed source, ot reviewed or opensource widely reviewed?
none of them? well than shut down your computer at all
