Ten checks that close the most common gaps in a small cloud estate.
Why a checklist beats a big project
Growing teams add servers, tools and people faster than they add rules. A short checklist that anyone can run closes the common gaps without a long security programme. The checks below apply to any major cloud provider.
The ten checks
- Turn on multi-factor login for every person, starting with administrators. Done when: nobody can sign in with a password alone.
- Lock away the owner (root) account. Use it only for rare account-level tasks, with a strong password, multi-factor login and no access keys. Done when: daily work uses named user accounts.
- Give least-privilege access. Start people with no access and add only what the job needs, through roles or groups rather than one-off permissions. Done when: nobody has full admin "just in case".
- Remove long-lived keys. Prefer short-lived credentials and service roles. Rotate any key you must keep. Done when: no key is older than your rotation limit.
- Keep secrets out of code and chat. Store passwords and API keys in a secrets manager, and scan repositories for leaked keys. Done when: no secret lives in a code file, a ticket or a message.
- Close what faces the internet. List every public address, open port and public storage bucket; shut anything that does not need to be public, especially remote-login ports. Done when: each public item has a named owner and a reason.
- Encrypt data in transit and at rest. Use HTTPS everywhere and switch on encryption for disks, databases and storage. Done when: an unencrypted store would fail your review.
- Patch and standardize. Turn on automatic operating-system updates, build servers from maintained base images and update dependencies on a schedule. Done when: you can name the oldest unpatched system and its date.
- Back up and prove you can restore. Keep backups in a separate account or location and test a restore every quarter. Done when: you have restored real data within a time you accept.
- Log, alert and review access. Turn on audit logs, store them somewhere separate and alert on risky events: a new administrator, a login from an unusual country, a public bucket created. Review who has access each quarter and remove leavers the same day. Done when: a risky change would reach a person within minutes.
Your first week
Which cloud provider does this apply to?
All of them. Names differ, but the ideas are the same.
Does this make us compliant?
No. It is a strong starting point, not a certification. Compliance needs policies, evidence and often an audit.
When should we bring in outside help?
When you hold sensitive customer data, have more than one environment, or cannot answer who has access to what within a day.
