Consider a computer system with three users, alice, bob and cindy. alice owns the file alicerc, and bob and cindy can read it. cindy can read the write the file bobrc, which bob owns, but alice can only read it. only cindy can read and write the file cyndyrc, which she owns. assume that the owner of each of these files can execute it. create the corresponding access control matrix cindy gives alice permission to read cyndyrc, and alice removes bob's ability to rad alicerc. show the new access control matrix.

The first access control matrix:

                   Alice       Bob      Cindy

alicerc          rwx            r            r

bobrc              r            rwx          rw

cyndyrc                                      rwx      

The access control matrix after the new permissions:

                    Alice       Bob      Cindy

alicerc           rwx                         r              

bobrc              r             rwx       rw

cyndyrc          r                          rwx      

well you could find somebody who doesn't want theirs and ask for it or possibly trick a dealer into giving it to you for free.

browsing like internet search? don't look at anything stupid. or set up restrictions on ur device's search engine. and if something suspicious comes up don't be dumb and click on it. i hope that's what ur question meant.
