# 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

`MINIO_BROWSER_REDIRECT_URL=https://console.minio.example.org`. This will ensure that the redirect URL is set to `https://console.minio.example.org/oauth_callback` and the login process should work correctly.

For deployments employing DNS round-robin on a single domain to all the MinIO servers, it is possible that after redirection the browser may land on a different MinIO server. For example, the domain `console.minio.example.org` may resolve to `console-X.minio.example.org`, where `X` is...

- MinIO verifies that the client certificate is valid.
- MinIO tries to find a policy that matches the `CN` of the client certificate.
- MinIO returns temp. S3 credentials associated to the found policy.

The returned credentials expiry after a certain period of time that can be configured via `&DurationSeconds=3600`. By default, the STS credentials are valid for 1 hour. The minimum expiration allowed is 15 minutes.

More details about supported KMS implementations and configuration can be found at the [KMS guide](https://github.com/minio/minio/blob/master/docs/kms/README.md).

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

It was found that the directory staging committer was the fastest among the three, S3A connector should be configured with the following parameters for optimal results:

```
cat ${HADOOP_CONF_DIR}/core-site.xml | kv-pairify | grep "s3a"

Once successfully set restart the MinIO instance.

```
mc admin service restart myminio
```

### Using WebIdentiy API

Client ID can be found by clicking any of the clients listed [here](http://localhost:8080/auth/admin/master/console/#/realms/minio/clients). If you have followed the above steps docs, the default Client ID will be `account`.

**In our tests we also found ext4 does not honor POSIX O_DIRECT/Fdatasync semantics, ext4 trades performance for consistency guarantees. Please avoid ext4 in your setup.**
