Hi All,
Today a friend of mine showed me a security feature in Windows XP, which to my knowledge is not available under Linux.(Please tell me I am wrong).
So here goes, he showed me a security feature in Windows XP wherein the user can setup a custom access to their own files and restrict access to others, including Adminstrators.
What he did not tell you is that Administrator is the 'baap' of the system and when annoyed, he can take ownership of any folder/file and throw the delinquent user out. These are security features of the NTFS file system, not Windows XP. The problem starts when you receive legitimate files from outsiders by email and you try to save them on these partitions over the LAN. It does not allow you to do it even when you become owner of the file and you have write permissions to the folder.
Is there a way to do so in GNU/Linux systems (for root)? As I am not aware of any means, I was not able to give him any answers. This feature came to light when we were discussing our Company's adoption of IS)-27001. He has also claimed that this is also the reason why Linux adoption in Enterprises is very low.
Linux does not believe in semi permissions. It is either yes or no for the user.
