client can request temp. S3 credentials via the STS API. It can authenticate via a client certificate and obtain a access/secret key pair as well as a session token. These credentials are associated to an S3 policy at the MinIO server.

In case of certificate-based authentication, MinIO has to map the client-provided certificate to an S3 policy. MinIO does this via the subject common name field of the X.509 certificate. So, MinIO will associate a certificate with a subject `CN = foobar` to...

Using above tier, set up a lifecycle rule with transition:

```
 mc ilm add --expiry-days 365 --transition-days 45 --storage-class "AZURETIER" myminio/srcbucket
```

Note: In the case of S3, it is possible to create a tier from MinIO running in EC2 to S3 using AWS role attached to EC2 as credentials instead of accesskey/secretkey:

# Vulnerability Management Policy

This document formally describes the process of addressing and managing a
reported vulnerability that has been found in the MinIO server code base,
any directly connected ecosystem component or a direct / indirect dependency
of the code base.

## Scope

The vulnerability management policy described in this document covers the
process of investigating, assessing and resolving a vulnerability report

## Metrics Request Handling

Each endpoint below can be queried at different intervals as needed via a scrape configuration in Prometheus or a compatible metrics collection tool.

For ease of configuration, each (non-empty) parent of the path serves all metric endpoints that are at descendant paths. For example, to query all system metrics one needs to only scrape `/minio/metrics/v3/system/`.

## Overview

MinIO implements an S3 extension to list, stat and download files inside a ZIP file stored in any bucket. A perfect use case scenario is when you have a lot of small files archived in multiple ZIP files. Uploading them is faster than uploading small files individually. Besides, your S3 applications will be able to access to the data with little performance overhead.

NOTE:

- `timeToFirstByte` and `timeToResponse` will be expressed in Nanoseconds.
- Additionally in the case of the erasure coded setup `tags.objectErasureMap` provides per object details about
  - Pool number the object operation was performed on.
  - Set number the object operation was performed on.

```
mc admin service restart myminio
```

### Using WebIdentiy API

On another terminal run `web-identity.go` a sample client application which obtains JWT id_tokens from an identity provider, in our case its Keycloak. Uses the returned id_token response to get new temporary credentials from the MinIO server using the STS API call `AssumeRoleWithWebIdentity`.

```

## List of Amazon S3 API's not supported on MinIO

object or object version requested qualifies for replication and is missing on one site, but present on the other. This allows the applications to take full advantage of two-way replication even before the two sites get fully synced.

In the case of multi destination replication, the replication status shows `COMPLETED` only after the replication operation succeeds on each of the targets specified in the replication configuration. If multiple targets are configured to use active-active replication...

> Does this mean I need an enterprise KMS setup to run MinIO (securely)?

No, MinIO does not depend on any third-party KMS provider. You have three options here:

- Run MinIO without a KMS. In this case all IAM data will be stored in plain-text.
- Run MinIO with a single secret key. MinIO supports a static cryptographic key
  that can act as minimal KMS. With this method all IAM data will be stored
