Here are some of the things we can learn from the Moris worm:

1) DO NOT CREATE PRODUCTS WITH DEFAULT PASSWORDS - I believe that the Moris worm spread because some versions of Unix had default passwords and users never changed the default password.

2) PROMPTLY INSTALL SECURITY PATCHES - I also believe the Moris worm spread by exploiting know security vulnerabilities.

Here are some other lessons: - Use strong random passwords - For best results, use a password with 20-24 characters (i.e. about 128 bits of entropy).

- Always change default passwords
