==Part 2: Making sshd More Secure ==
Anytime you configure your computer to allow logins from the network you are leaving yourself '''vulnerable to potential unauthorized access''' by so called "hackers". Running the sshd service is a fairly common practice but '''care must be taken to make things more difficult for those hackers that attempt to use "brute force" attacks to gain access to your system. Hackers use their knowledge of your system and many password guesses to gain access'''. They know which port is likely open to attack (TCP:22), the administrative account name (root), all they need to do is to "guess" the password.<br><br> Making your root password (and all other accounts!) both quite complex but easy to remember is not hard. '''Passwords should be a minimum of 8 characters long''', preferably longer, contain upper and lower case letters, numbers, and special characters. A good example of a strong password might be "LotR3--RotK." This is not that hard to remember as it corresponds to a book title. "Lord of the Rings 3 Return of the King." The password "P@ssw0rd!" is not as good because it is quite obvious and common.
