The short and sweet answer:
1) Use the chmod tool to remove the "others read/write/execute" permission bits from the directories that you don't want others to be viewing. A command like
chmod 750 /path/to/directory/root
should do the trick. You might even want to consider the -R option for recursive application of these permissions.
Note: if you don't use the recursive option, you might be able to ls or cd into a subdirectory even if the parent directory has the permissions disabled.
2) For an explanation of why this works, just have a look at this site: http://www.perlfect.com/articles/chmod.shtml - the directory permissions section should make things clear.
A short synopsis is:
Read permission on a directory - Allows ls to list the files in the directory
Write permission on a directory - Allows files to be deleted
Execute permission on a directory - Allows a user to cd into the directory
Technically:
Read - Read the directory inode and hence list the files and related info
Write - Modify the directory inode
Execute - Allow a chdir(...) system call to succeed on the particular inode
Removing these permissions is akin to saying that you don't want anybody else messing around with this inode (that you own).
