I use the below module as a layer of security between my database accessing perl scripts and potential trouble makers. I'm sure there are better ways to implement this, however this is what I use.

My question is regarding the directory and file permissions of the module and the directory containing the module. What settings would be the most secure. This will be hosted on a shared UNIX hosting provider. Currently both file and directory are set at 755.

Thanks. 
package DB;

use strict;
use DBI;

sub connect
{
my $db_name = "xxx";
my $host_name = "xxx";
my $user_name = "xxxxxx";
my $password = "xxxx";
my $dsn = "DBI:mysql:host=$host_name;database=$db_name";

return (DBI->connect ($dsn, $user_name, $password,
{ PrintError => 0, RaiseError => 1}));
}

If there are safer means of accomplishing this ( removing user and pass info out of the script ) please mention them.
