What is the difference between Norton Internet Security and Norton Security?

The difference between Norton Internet Security and Norton Security is in the fact the later one has replaced the other one.

Since October 2014, Norton Internet Security has been moved to the Norton legacy products group (discontinued). This was due to the release of the new security product for consumers and small business: Norton Security.

Then, in 2019, Norton Security got replaced by Norton 360.
