File: serverless-application-model/latest/developerguide/prerequisites.md

Summary

Updated URLs and added new section recommending temporary credentials for IAM users with implementation guides

Security assessment

The changes emphasize using temporary credentials (security best practice) and provide implementation links. While this promotes security hygiene, there's no evidence of addressing a specific vulnerability. The updates reinforce existing security documentation rather than introducing new vulnerabilities.
