AWS S3 read-only roles are either a lifesaver or a bottleneck, and the difference is in how you design them.
A poorly scoped IAM policy can expose sensitive data or lock out teams who need access. A well-scoped one lets developers pull what they need, keeps data safe, and passes every audit. The problem is that AWS S3 read-only access sounds simpler than it is. The default permissions aren’t always enough. The wrong wildcard breaks security. The wrong action omission breaks workflows.
The best feature request for AWS S3 read-only roles is actually about precision. A true read-only role should let you:
- List buckets and objects without touching writes
- Read object data without metadata leaks beyond need
- Prevent version deletions, ACL changes, or accidental public exposure
- Support granular path-level access
- Work seamlessly across accounts and S3 Storage Classes
Today, AWS offers the AmazonS3ReadOnlyAccess managed policy, but it’s blunt. It grants ListAllMyBuckets, full object reads, and broad listing—sometimes too broad. Organizations want more control without building custom JSON policies from scratch every time.
A better AWS read-only role feature would:
- Allow simple scoping to prefixes without touching complex condition keys.
- Reduce policy length for compliance review.
- Provide templates tuned for common patterns—static site read, analytics dataset read, log archive read.
- Include optional audit logging flags without requiring separate CloudTrail configs.
Security teams push for least privilege. Engineers push for productivity. Both can agree on prebuilt, tested read-only role variants that map exactly to workload needs. This closes attack surfaces and speeds up onboarding.
This request isn’t about adding something exotic to AWS S3. It’s about refining what’s already there so that granting read-only doesn’t require hours of IAM tuning, Stack Overflow searches, and policy simulator tests.
