You wish to bring up concerns about security with brother. He asks you that if Internet is inherently not secure, then why are so many business, government, and military transactions processed online? Your brother thinks that security risks for Grandma's Treats are minimal to non-existent. You reply that security is still significant, even to business like his, and it should be approached in methodical way.
Educate brother by creating short research paper or presentation. Write some security concerns that Grandma's Treats must address as it considers how to create web presence. Write down the risks? How can they be decreased? Are you confident that Internet is, or can be, secure enough to tackle these transactions for Grandma's Treats or other more information-sensitive businesses?
