What scope does an "Everyone" principal have in Amazon SQS permissions?

Question

When specifying permissions on an Amazon AWS SQS queue you can specify a principal or say Everyone. What does Everyone mean? This is not explicitly document anywhere I could find.

Does this mean "anyone in my AWS account" or "the whole world including evil hackers"?

Answer 1

Everyone means everyone, with or without an AWS account - so unless you want to be on the hook for potential abuse, probably not a good idea unless you restricted with appropriate conditions, i.e. by IP Address.
