In this blog post, we will explore best practices for leveraging CloudHSM to enhance performance and avoid common configuration issues. This fully-managed hardware security module (HSM) service automates various management tasks, allowing you to focus on user management and application integration.
Administration of CloudHSM
Managing your CloudHSM cluster involves several key steps. First, you need to initialize your cluster with a customer key pair. Begin by generating a new RSA key pair, referred to as the customer key pair. After generating this, create a self-signed certificate and sign the cluster’s certificate using your customer private key. It’s imperative to securely generate and store this private key, as it is the binding secret between you and your cluster, which cannot be rotated. For added security, consider creating the customer private key in an offline HSM and storing it securely.
Key Management with Crypto User Accounts
Crypto users (CUs) are essential for generating, managing, and using keys within CloudHSM. It’s advisable to have multiple CUs with distinct scopes to facilitate better security management. For instance, you may allocate different CUs for various key classes or use one CU to create keys and share them with others. This strategy can simplify the process of rotating credentials in production.
Caution: When deleting CU accounts, ensure that you do not remove the owner CU of a key, as this will render the key unusable. Use the command cloudhsm_mgmt_util findAllKeys to identify keys owned by a specific CU and consider labeling keys for easier management.
Managing Crypto Officer Accounts
Crypto officers (COs) perform vital user management tasks. When modifying user accounts or passwords, it’s crucial to connect to all HSMs in the cluster to ensure synchronization. Utilizing the Configure tool with the –m option before making changes is a best practice to avoid inconsistencies. Additionally, keeping a secure record of passwords will prevent lockouts due to mismatched credentials.
Using quorum authentication is highly recommended to prevent a single CO from making unauthorized changes. This system requires a minimum number of COs to authorize any operation, ensuring that your cluster remains secure. Always maintain a minimum number of COs above your quorum requirement to avoid administrative lockouts.
Configuration Best Practices
While CloudHSM is a managed service, the configuration within an Amazon Virtual Private Cloud (VPC) is still your responsibility. Optimizing the number of HSMs and their deployment across multiple Availability Zones (AZs) enhances the resilience of your setup. An AZ consists of one or more physical data centers, ensuring redundancy in power, networking, and connectivity.
