How to migrate your EC2 Oracle Transparent Data Encryption (TDE) database encryption wallet to CloudHSM

Post Syndicated from Tracy Pierce original https://aws.amazon.com/blogs/security/how-to-migrate-your-ec2-oracle-transparent-data-encryption-tde-database-encryption-wallet-to-cloudhsm/

In this post, I’ll show you how to migrate an encryption wallet for an Oracle database installed on Amazon EC2 from using an outside HSM to using AWS CloudHSM. Transparent Data Encryption (TDE) for Oracle is a common use case for Hardware Security Module (HSM) devices like AWS CloudHSM. Oracle TDE uses what is called “envelope encryption.” Envelope encryption is when the encryption key used to encrypt the tables of your database is in turn encrypted by a master key that resides either in a software keystore or on a hardware keystore, like an HSM. This master key is non-exportable by design to protect the confidentiality and integrity of your database encryption. This gives you a more granular encryption scheme on your data.

An encryption wallet is an encrypted container used to store the TDE master key for your database. The encryption wallet needs to be opened manually after a database startup and prior to the TDE encrypted data being accessed, so the master key is available for data decryption. The process I talk about in this post can be used with any non-AWS hardware or software encryption wallet, or a hardware encryption wallet that utilizes AWS CloudHSM Classic. For my examples in this tutorial, I will be migrating from a CloudHSM Classic to a CloudHSM cluster. It is worth noting that Gemalto has announced the end-of-life for Luna 5 HSMs, which our CloudHSM Classic fleet uses.

Note: You cannot migrate from an Oracle instance in
Amazon Relational Database Service (Amazon RDS) to AWS CloudHSM. You must install the Oracle database on an Amazon EC2 instance. Amazon RDS is not currently integrated with AWS CloudHSM.

When you move from one type of encryption wallet to another, new TDE master keys are created inside the new wallet. To ensure that you have access to backups that rely on your old HSM, consider leaving the old HSM running for your normal recovery window period. The steps I discuss will perform the decryption of your TDE keys and then re-encrypt them with the new TDE master key for you.

Once you’ve migrated your Oracle databases to use AWS CloudHSM as your encryption wallet, it’s also a good idea to set up cross-region replication for disaster recovery efforts. With copies of your database and encryption wallet in another region, you can be back in production quickly should a disaster occur. I’ll show you how to take advantage of this by setting up cross-region snapshots of your Oracle database Amazon Elastic Block Store (EBS) volumes and copying backups of your CloudHSM cluster between regions.

Solution overview

For this solution, you will modify the Oracle database’s encryption wallet to use AWS CloudHSM. This is completed in three steps, which will be detailed below. First, you will switch from the current encryption wallet, which is your original HSM device, to a software wallet. This is done by reverse migrating to a local wallet. Second, you’ll replace the PKCS#11 provider of your original HSM with the CloudHSM PKCS#11 software library. Third, you’ll switch the encryption wallet for your database to your CloudHSM cluster. Once this process is complete, your database will automatically re-encrypt all data keys using the new master key.

To complete the disaster recovery (DR) preparation portion of this post, you will perform two more steps. These consist of copying over snapshots of your EC2 volumes and your CloudHSM cluster backups to your DR region. The following diagram illustrates the steps covered in this post.

Figure 1: Steps to migrate your EC2 Oracle TDE database encryption wallet to CloudHSM

  1. Switch the current encryption wallet for the Oracle database TDE from your original HSM to a software wallet via a reverse migration process.
  2. Replace the PKCS#11 provider of your original HSM with the AWS CloudHSM PKCS#11 software library.
  3. Switch your encryption wallet to point to your AWS CloudHSM cluster.
  4. (OPTIONAL) Set up cross-region copies of the EC2 instance housing your Oracle database
  5. (OPTIONAL) Set up a cross-region copy of your recent CloudHSM cluster backup

Prerequisites

This process assumes you have the below items already set up or configured:

Deploy the solution

Now that you have the basic steps, I’ll go into more detail on each of them. I’ll show you the steps to migrate your encryption wallet to a software wallet using a reverse migration command.

Step 1: Switching the current encryption wallet for the Oracle database TDE from your original HSM to a software wallet via a reverse migration process.

To begin, you must configure the sqlnet.ora file for the reverse migration. In Oracle databases, the sqlnet.ora file is a plain-text configuration file that contains information like encryption, route of connections, and naming parameters that determine how the Oracle server and client must use the capabilities for network database access. You will want to create a backup so you can roll back in the event of any errors. You can make a copy with the below command. Make sure to replace </path/to/> with the actual path to your sqlnet.ora file location. The standard location for this file is “$ORACLE_HOME/network/admin“, but check your setup to ensure this is correct.

cp </path/to/>sqlnet.ora </path/to/>sqlnet.ora.backup

The software wallet must be created before you edit this file, and it should preferably be empty. Then, using your favorite text editor, open the sqlnet.ora file and set the below configuration. If an entry already exists, replace it with the below text.


ENCRYPTION_WALLET_LOCATION=
  (SOURCE=(METHOD=FILE)(METHOD_DATA=
    (DIRECTORY=<path_to_keystore>)))

Make sure to replace the <path_to_keystore> with the directory location of your destination wallet. The destination wallet is the path you choose for the local software wallet. You will notice in Oracle the words “keystore” and “wallet” are interchangeable for this post. Next, you’ll configure the wallet for the reverse migration. For this, you will use the ADMINISTER KEY MANAGEMENT statement with the SET ENCRYPTION KEY and REVERSE MIGRATE clauses as shown in the example below.

By using the REVERSE MIGRATE USING clause in your statement, you ensure the existing TDE table keys and tablespace encryption keys are decrypted by the hardware wallet TDE master key and then re-encrypted with the software wallet TDE master key. You will need to log into the database instance as a user that has been granted the ADMINISTER KEY MANAGEMENT or SYSKM privileges to run this statement. An example of the login is below. Make sure to replace the <sec_admin> and <password> with your administrator user name and password for the database.


sqlplus c##<sec_admin> syskm
Enter password: <password> 
Connected.

Once you’re connected, you’ll run the SQL statement below. Make sure to replace <password> with your own existing wallet password and <username:password> with your own existing wallet user ID and password. We are going to run this statement with the WITH BACKUP parameter, as it’s always ideal to take a backup in case something goes incorrectly.

ADMINISTER KEY MANAGEMENT SET ENCRYPTION KEY IDENTIFIED BY <password> REVERSE MIGRATE USING “<username:password>” WITH BACKUP;

If successful, you will see the text keystore altered. When complete, you do not need to restart your database or manually re-open the local wallet as the migration process loads this into memory for you.

With the migration complete, you’ll now move onto the next step of replacing the PKCS#11 provider of your original HSM with the CloudHSM PKCS#11 software library. This library is a PKCS#11 standard implementation that communicates with the HSMs in your cluster and is compliant with PKCS#11 version 2.40.

Step 2: Replacing the PKCS#11 provider of your original HSM with the AWS CloudHSM PKCS#11 software library.

You’ll begin by installing the software library with the below two commands.

wget https://s3.amazonaws.com/cloudhsmv2-software/CloudHsmClient/EL6/cloudhsm-client-pkcs11-latest.el6.x86_64.rpm

sudo yum install -y ./cloudhsm-client-pkcs11-latest.el6.x86_64.rpm

When installation completes, you will be able to find the CloudHSM PKCS#11 software library files in the directory, the default directory for AWS CloudHSM’s software library installs. To ensure processing speed and throughput capabilities of the HSMs, I suggest installing a Redis cache as well. This cache stores key handles and attributes locally, so you may access them without making a call to the HSMs. As this step is optional and not required for this post, I will leave the link for installation instructions here. With the software library installed, you want to ensure the CloudHSM client is running. You can check this with the command below.

sudo start cloudhsm-client

Step 3: Switching your encryption wallet to point to your AWS CloudHSM cluster.

Once you’ve verified the client is running, you’re going to create another backup of the sqlnet.ora file. It’s always a good idea to take backups before making any changes. The command would be similar to below, replacing </path/to/> with the actual path to your sqlnet.ora file.

cp </path/to/>sqlnet.ora </path/to/>sqlnet.ora.backup2

With this done, again open the sqlnet.ora file with your favorite text editor. You are going to edit the line encryption_wallet_location to resemble the below text.


ENCRYPTION_WALLET_LOCATION=
  (SOURCE=(METHOD=HSM))

Save the file and exit. You will need to create the directory where your Oracle database will expect to find the library file for the AWS CloudHSM PKCS#11 software library. You do this with the command below.

sudo mkdir -p /opt/oracle/extapi/64/hsm

With the directory created, you next copy over the CloudHSM PKCS#11 software library from the original installation directory to this one. It is important this new directory only contain the one library file. Should any files exist in the directory that are not directly related to the way you installed the CloudHSM PKCS#11 software library, remove them. The command to copy is below.

sudo cp /opt/cloudhsm/lib/libcloudhsm_pkcs11_standard.so /opt/oracle/extapi/64/hsm

Now, modify the ownership of the directory and everything inside. The Oracle user must have access to these library files to run correctly. The command to do this is below.

sudo chown -R oracle:dba /opt/oracle

With that done, you can start your Oracle database. This completes the migration of your encryption wallet and TDE keys from your original encryption wallet to a local wallet, and finally to CloudHSM as the new encryption wallet. Should you decide you wish to create new TDE master encryption keys on CloudHSM, you can follow the steps here to do so.

These steps are optional, but helpful in the event you must restore your database to production quickly. For customers that leverage DR environments, we have two great blog posts here and here to walk you through each step of the cross-region replication process. The first uses a combination of AWS Step Functions and Amazon CloudWatch Events to copy your EBS snapshots to your DR region, and the second showcases how to copy your CloudHSM cluster backups to your DR region.

Summary

In this post, I walked you through how to migrate your Oracle TDE database encryption wallet to point it to CloudHSM for secure storage of your TDE. I showed you how to properly install the CloudHSM PKCS#11 software library and place it in the directory for Oracle to find and use. This process can be used to migrate most on-premisis encryption wallet to AWS CloudHSM to ensure security of your TDE keys and meet compliance requirements.

How to use AWS Secrets Manager to rotate credentials for all Amazon RDS database types, including Oracle

Post Syndicated from Apurv Awasthi original https://aws.amazon.com/blogs/security/how-to-use-aws-secrets-manager-rotate-credentials-amazon-rds-database-types-oracle/

You can now use AWS Secrets Manager to rotate credentials for Oracle, Microsoft SQL Server, or MariaDB databases hosted on Amazon Relational Database Service (Amazon RDS) automatically. Previously, I showed how to rotate credentials for a MySQL database hosted on Amazon RDS automatically with AWS Secrets Manager. With today’s launch, you can use Secrets Manager to automatically rotate credentials for all types of databases hosted on Amazon RDS.

In this post, I review the key features of Secrets Manager. You’ll then learn:

  1. How to store the database credential for the superuser of an Oracle database hosted on Amazon RDS
  2. How to store the Oracle database credential used by an application
  3. How to configure Secrets Manager to rotate both Oracle credentials automatically on a schedule that you define

Key features of Secrets Manager

AWS Secrets Manager makes it easier to rotate, manage, and retrieve database credentials, API keys, and other secrets throughout their lifecycle. The key features of this service include the ability to:

  1. Secure and manage secrets centrally. You can store, view, and manage all your secrets centrally. By default, Secrets Manager encrypts these secrets with encryption keys that you own and control. You can use fine-grained IAM policies or resource-based policies to control access to your secrets. You can also tag secrets to help you discover, organize, and control access to secrets used throughout your organization.
  2. Rotate secrets safely. You can configure Secrets Manager to rotate secrets automatically without disrupting your applications. Secrets Manager offers built-in integrations for rotating credentials for all Amazon RDS databases (MySQL, PostgreSQL, Oracle, Microsoft SQL Server, MariaDB, and Amazon Aurora.) You can also extend Secrets Manager to meet your custom rotation requirements by creating an AWS Lambda function to rotate other types of secrets.
  3. Transmit securely. Secrets are transmitted securely over Transport Layer Security (TLS) protocol 1.2. You can also use Secrets Manager with Amazon Virtual Private Cloud (Amazon VPC) endpoints powered by AWS Privatelink to keep this communication within the AWS network and help meet your compliance and regulatory requirements to limit public internet connectivity.
  4. Pay as you go. Pay for the secrets you store in Secrets Manager and for the use of these secrets; there are no long-term contracts, licensing fees, or infrastructure and personnel costs. For example, a typical production-scale web application will generate an estimated monthly bill of $6. If you follow along the instructions in this blog post, your estimated monthly bill for Secrets Manager will be $1. Note: you may incur additional charges for using Amazon RDS and Amazon Lambda, if you’ve already consumed the free tier for these services.

Now that you’re familiar with Secrets Manager features, I’ll show you how to store and automatically rotate credentials for an Oracle database hosted on Amazon RDS. I divided these instructions into three phases:

  1. Phase 1: Store and configure rotation for the superuser credential
  2. Phase 2: Store and configure rotation for the application credential
  3. Phase 3: Retrieve the credential from Secrets Manager programmatically

Prerequisites

To follow along, your AWS Identity and Access Management (IAM) principal (user or role) requires the SecretsManagerReadWrite AWS managed policy to store the secrets. Your principal also requires the IAMFullAccess AWS managed policy to create and configure permissions for the IAM role used by Lambda for executing rotations. You can use IAM permissions boundaries to grant an employee the ability to configure rotation without also granting them full administrative access to your account.

Phase 1: Store and configure rotation for the superuser credential

From the Secrets Manager console, on the right side, select Store a new secret.

Since I’m storing credentials for database hosted on Amazon RDS, I select Credentials for RDS database. Next, I input the user name and password for the superuser. I start by securing the superuser because it’s the most powerful database credential and has full access to the database.
 

Figure 1: For "Select secret type," choose "Credentials for RDS database"

Figure 1: For “Select secret type,” choose “Credentials for RDS database”

For this example, I choose to use the default encryption settings. Secrets Manager will encrypt this secret using the Secrets Manager DefaultEncryptionKey in this account. Alternatively, I can choose to encrypt using a customer master key (CMK) that I have stored in AWS Key Management Service (AWS KMS). To learn more, read the Using Your AWS KMS CMK documentation.
 

Figure 2: Choose either DefaultEncryptionKey or use a CMK

Figure 2: Choose either DefaultEncryptionKey or use a CMK

Next, I view the list of Amazon RDS instances in my account and select the database this credential accesses. For this example, I select the DB instance oracle-rds-database from the list, and then I select Next.

I then specify values for Secret name and Description. For this example, I use Database/Development/Oracle-Superuser as the name and enter a description of this secret, and then select Next.
 

Figure 3: Provide values for "Secret name" and "Description"

Figure 3: Provide values for “Secret name” and “Description”

Since this database is not yet being used, I choose to enable rotation. To do so, I select Enable automatic rotation, and then set the rotation interval to 60 days. Remember, if this database credential is currently being used, first update the application (see phase 3) to use Secrets Manager APIs to retrieve secrets before enabling rotation.
 

Figure 4: Select "Enable automatic rotation"

Figure 4: Select “Enable automatic rotation”

Next, Secrets Manager requires permissions to rotate this secret on my behalf. Because I’m storing the credentials for the superuser, Secrets Manager can use this credential to perform rotations. Therefore, on the same screen, I select Use a secret that I have previously stored in AWS Secrets Manager, and then select Next.

Finally, I review the information on the next screen. Everything looks correct, so I select Store. I have now successfully stored a secret in Secrets Manager.

Note: Secrets Manager will now create a Lambda function in the same VPC as my Oracle database and trigger this function periodically to change the password for the superuser. I can view the name of the Lambda function on the Rotation configuration section of the Secret Details page.

The banner on the next screen confirms that I’ve successfully configured rotation and the first rotation is in progress, which enables me to verify that rotation is functioning as expected. Secrets Manager will rotate this credential automatically every 60 days.
 

Figure 5: The confirmation notification

Figure 5: The confirmation notification

Phase 2: Store and configure rotation for the application credential

The superuser is a powerful credential that should be used only for administrative tasks. To enable your applications to access a database, create a unique database credential per application and grant these credentials limited permissions. You can use these database credentials to read or write to database tables required by the application. As a security best practice, deny the ability to perform management actions, such as creating new credentials.

In this phase, I will store the credential that my application will use to connect to the Oracle database. To get started, from the Secrets Manager console, on the right side, select Store a new secret.

Next, I select Credentials for RDS database, and input the user name and password for the application credential.

I continue to use the default encryption key. I select the DB instance oracle-rds-database, and then select Next.

I specify values for Secret Name and Description. For this example, I use Database/Development/Oracle-Application-User as the name and enter a description of this secret, and then select Next.

I now configure rotation. Once again, since my application is not using this database credential yet, I’ll configure rotation as part of storing this secret. I select Enable automatic rotation, and set the rotation interval to 60 days.

Next, Secrets Manager requires permissions to rotate this secret on behalf of my application. Earlier in the post, I mentioned that applications credentials have limited permissions and are unable to change their password. Therefore, I will use the superuser credential, Database/Development/Oracle-Superuser, that I stored in Phase 1 to rotate the application credential. With this configuration, Secrets Manager creates a clone application user.
 

Figure 6: Select the superuser credential

Figure 6: Select the superuser credential

Note: Creating a clone application user is the preferred mechanism of rotation because the old version of the secret continues to operate and handle service requests while the new version is prepared and tested. There’s no application downtime while changing between versions.

I review the information on the next screen. Everything looks correct, so I select Store. I have now successfully stored the application credential in Secrets Manager.

As mentioned in Phase 1, AWS Secrets Manager creates a Lambda function in the same VPC as the database and then triggers this function periodically to rotate the secret. Since I chose to use the existing superuser secret to rotate the application secret, I will grant the rotation Lambda function permissions to retrieve the superuser secret. To grant this permission, I first select role from the confirmation banner.
 

Figure 7: Select the "role" link that's in the confirmation notification

Figure 7: Select the “role” link that’s in the confirmation notification

Next, in the Permissions tab, I select SecretsManagerRDSMySQLRotationMultiUserRolePolicy0. Then I select Edit policy.
 

Figure 8: Edit the policy on the "Permissions" tab

Figure 8: Edit the policy on the “Permissions” tab

In this step, I update the policy (see below) and select Review policy. When following along, remember to replace the placeholder ARN-OF-SUPERUSER-SECRET with the ARN of the secret you stored in Phase 1.


{
  "Statement": [
    {
        "Effect": "Allow",
        "Action": [
            "ec2:CreateNetworkInterface",
			"ec2:DeleteNetworkInterface",
			"ec2:DescribeNetworkInterfaces",
			"ec2:DetachNetworkInterface"
		],
		"Resource": "*"
	},
	{
	    "Sid": "GrantPermissionToUse",
		"Effect": "Allow",
		"Action": [
            "secretsmanager:GetSecretValue"
        ],
		"Resource": "ARN-OF-SUPERUSER-SECRET"
	}
  ]
}

Here’s what it will look like:
 

Figure 9: Edit the policy

Figure 9: Edit the policy

Next, I select Save changes. I have now completed all the steps required to configure rotation for the application credential, Database/Development/Oracle-Application-User.

Phase 3: Retrieve the credential from Secrets Manager programmatically

Now that I have stored the secret in Secrets Manager, I add code to my application to retrieve the database credential from Secrets Manager. I use the sample code from Phase 2 above. This code sets up the client and retrieves and decrypts the secret Database/Development/Oracle-Application-User.

Remember, applications require permissions to retrieve the secret, Database/Development/Oracle-Application-User, from Secrets Manager. My application runs on Amazon EC2 and uses an IAM role to obtain access to AWS services. I attach the following policy to my IAM role. This policy uses the GetSecretValue action to grant my application permissions to read secret from Secrets Manager. This policy also uses the resource element to limit my application to read only the Database/Development/Oracle-Application-User secret from Secrets Manager. You can refer to the Secrets Manager Documentation to understand the minimum IAM permissions required to retrieve a secret.


{
 "Version": "2012-10-17",
 "Statement": {
    "Sid": "RetrieveDbCredentialFromSecretsManager",
    "Effect": "Allow",
    "Action": "secretsmanager:GetSecretValue",
    "Resource": "arn:aws:secretsmanager:<AWS-REGION>:<ACCOUNT-NUMBER>:secret: Database/Development/Oracle-Application-User     
 }
}

In the above policy, remember to replace the placeholder <AWS-REGION> with the AWS region that you’re using and the placeholder <ACCOUNT-NUMBER> with the number of your AWS account.

Summary

I explained the key benefits of Secrets Manager as they relate to RDS and showed you how to help meet your compliance requirements by configuring Secrets Manager to rotate database credentials automatically on your behalf. Secrets Manager helps you protect access to your applications, services, and IT resources without the upfront investment and on-going maintenance costs of operating your own secrets management infrastructure. To get started, visit the Secrets Manager console. To learn more, visit Secrets Manager documentation.

Build your own weather station with our new guide!

Post Syndicated from Richard Hayler original https://www.raspberrypi.org/blog/build-your-own-weather-station/

One of the most common enquiries I receive at Pi Towers is “How can I get my hands on a Raspberry Pi Oracle Weather Station?” Now the answer is: “Why not build your own version using our guide?”

Build Your Own weather station kit assembled

Tadaaaa! The BYO weather station fully assembled.

Our Oracle Weather Station

In 2016 we sent out nearly 1000 Raspberry Pi Oracle Weather Station kits to schools from around the world who had applied to be part of our weather station programme. In the original kit was a special HAT that allows the Pi to collect weather data with a set of sensors.

The original Raspberry Pi Oracle Weather Station HAT – Build Your Own Raspberry Pi weather station

The original Raspberry Pi Oracle Weather Station HAT

We designed the HAT to enable students to create their own weather stations and mount them at their schools. As part of the programme, we also provide an ever-growing range of supporting resources. We’ve seen Oracle Weather Stations in great locations with a huge differences in climate, and they’ve even recorded the effects of a solar eclipse.

Our new BYO weather station guide

We only had a single batch of HATs made, and unfortunately we’ve given nearly* all the Weather Station kits away. Not only are the kits really popular, we also receive lots of questions about how to add extra sensors or how to take more precise measurements of a particular weather phenomenon. So today, to satisfy your demand for a hackable weather station, we’re launching our Build your own weather station guide!

Build Your Own Raspberry Pi weather station

Fun with meteorological experiments!

Our guide suggests the use of many of the sensors from the Oracle Weather Station kit, so can build a station that’s as close as possible to the original. As you know, the Raspberry Pi is incredibly versatile, and we’ve made it easy to hack the design in case you want to use different sensors.

Many other tutorials for Pi-powered weather stations don’t explain how the various sensors work or how to store your data. Ours goes into more detail. It shows you how to put together a breadboard prototype, it describes how to write Python code to take readings in different ways, and it guides you through recording these readings in a database.

Build Your Own Raspberry Pi weather station on a breadboard

There’s also a section on how to make your station weatherproof. And in case you want to move past the breadboard stage, we also help you with that. The guide shows you how to solder together all the components, similar to the original Oracle Weather Station HAT.

Who should try this build

We think this is a great project to tackle at home, at a STEM club, Scout group, or CoderDojo, and we’re sure that many of you will be chomping at the bit to get started. Before you do, please note that we’ve designed the build to be as straight-forward as possible, but it’s still fairly advanced both in terms of electronics and programming. You should read through the whole guide before purchasing any components.

Build Your Own Raspberry Pi weather station – components

The sensors and components we’re suggesting balance cost, accuracy, and easy of use. Depending on what you want to use your station for, you may wish to use different components. Similarly, the final soldered design in the guide may not be the most elegant, but we think it is achievable for someone with modest soldering experience and basic equipment.

You can build a functioning weather station without soldering with our guide, but the build will be more durable if you do solder it. If you’ve never tried soldering before, that’s OK: we have a Getting started with soldering resource plus video tutorial that will walk you through how it works step by step.

Prototyping HAT for Raspberry Pi weather station sensors

For those of you who are more experienced makers, there are plenty of different ways to put the final build together. We always like to hear about alternative builds, so please post your designs in the Weather Station forum.

Our plans for the guide

Our next step is publishing supplementary guides for adding extra functionality to your weather station. We’d love to hear which enhancements you would most like to see! Our current ideas under development include adding a webcam, making a tweeting weather station, adding a light/UV meter, and incorporating a lightning sensor. Let us know which of these is your favourite, or suggest your own amazing ideas in the comments!

*We do have a very small number of kits reserved for interesting projects or locations: a particularly cool experiment, a novel idea for how the Oracle Weather Station could be used, or places with specific weather phenomena. If have such a project in mind, please send a brief outline to [email protected], and we’ll consider how we might be able to help you.
