AWS prescriptive-guidance documentation change

Service: prescriptive-guidance · 2026-07-10 · Documentation low

File: prescriptive-guidance/latest/hybrid-cloud-best-practices/security.md

Summary

Updated image paths, fixed markdown table formatting, corrected punctuation in URLs, and adjusted documentation about service link security configurations. Added line break in firewall port table and fixed footnote formatting.

Security assessment

Changes primarily focus on documentation formatting and image reorganization. While the content discusses security configurations, the changes themselves don't introduce new security information or address specific vulnerabilities. The firewall port table formatting change doesn't alter security guidance.

-For AWS Outposts, the service link is a necessary connection between your Outposts server and your chosen AWS Region (or home Region) and allows for the management of the Outpost and the exchange of traffic to and from the AWS Region. The service link uses an AWS managed VPN to communicate with the home Region. Each host inside AWS Outposts creates a set of VPN tunnels to split control plane traffic and VPC traffic. Depending on the service link connectivity (internet or Direct Connect) for AWS Outposts, those tunnels require firewall ports to be opened for the service link to create the overlay on top of it. For detailed technical information about the security of AWS Outposts and the service link, see [Connectivity through service link](https://docs.aws.amazon.com/outposts/latest/userguide/service-links.html) and [Infrastructure security in AWS Outposts](https://docs.aws.amazon.com/outposts/latest/server-userguide/infrastructure-security.html) in the AWS Outposts documentation.
