HashiCorp Vault 1.18: A Comprehensive Overview of New Features and Enhancements
HashiCorp has announced the general availability of Vault 1.18, introducing several enhancements that improve secure workflows, expand high availability capabilities, and support new Public Key Infrastructure (PKI) protocols. Vault is a critical tool for managing secrets, encrypting data, and handling identity for applications operating across hybrid and multi-cloud infrastructures. This release continues to build on Vault’s reputation for robust security and operational efficiency.
Key Features in Vault 1.18
Vault 1.18 comes with several notable features that enhance its functionality. These include:
- CMPv2 PKI Support: The introduction of the CMPv2 PKI enrollment automation protocol caters to the 5G telecom industry, ensuring adherence to the 3GPP standards. The protocol facilitates seamless certificate management, crucial for telecommunications networks.
- Adaptive Overload Protection: Enhancements in high availability through adaptive overload protection help mitigate downtime by managing API request loads more efficiently. This feature is particularly beneficial during periods of high traffic, ensuring stable performance.
- Password Rotation for Static PostgreSQL Database Accounts: This feature empowers database accounts with the capability to self-rotate credentials, reducing the reliance on privileged accounts and enhancing security.
- Raft Library Updates: Updates to the Raft protocol improve resilience during network outages, ensuring more stable operations.
- IPv6 Compliance: With validation against U.S. government mandates, Vault is positioned to meet federal IPv6 policy requirements, making it suitable for government and enterprise use.
- Improved User Experience for Security Teams: Enhancements in the user interface (UI) support management of AWS Workload Identity Federation (WIF) and KVv2 secrets path, streamlining operations for security teams.
Detailed Exploration of Key Features
CMPv2 PKI Protocol Support
With Vault Enterprise 1.18, certificate lifecycle management becomes more sophisticated through the integration of the CMPv2 protocol. This protocol is essential for the mobile telecommunications industry, supporting 5G infrastructure by meeting the 3GPP standards. CMPv2 supports various certificate formats like RSA, DSA, and ECDSA, along with X.509 templates.
The CMPv2 protocol facilitates critical processes such as:
- Initialization Registration: This process allows new devices to join the PKI by using pre-provisioned vendor certificates.
- Certificate Update: This ensures that issued certificates are acknowledged and confirmed by the requesting client, maintaining the integrity of the PKI.
- Key-Pair Update: It allows for the renewal or reissuance of certificates, ensuring that network devices remain authenticated and compliant.
This enhancement in Vault Enterprise makes it easier for organizations to automate the enrollment of network device certificates, thus aligning with 3GPP compliance for 5G services.
Adaptive Overload Protection
In response to the demand for high availability, Vault 1.18 introduces adaptive overload protection. This feature manages API requests by maintaining write replicas, thereby reducing the risk of downtime. Such functionality is crucial during high traffic periods, ensuring that storage updates do not lead to operational slowdowns. This protection is enabled by default in Vault’s integrated storage backend for Enterprise users.
Password Rotation for Static Database Credentials
Vault’s database secrets engine now supports PostgreSQL static database accounts with a self-rotation feature for credentials. This allows individual accounts to manage their credentials independently, reducing the need for highly privileged non-human identity accounts. This development enhances database security and streamlines the management of database credentials.
Raft Library Updates
The Raft protocol in Vault has been updated to include pre-vote operations, significantly improving the system’s stability during network outages. This update ensures that applications remain stable and operational, even in the event of network failures. Importantly, this enhancement does not require any additional configuration for users of Vault Enterprise 1.18 and later.
IPv6 Compliance
Vault 1.18 has been validated to comply with the U.S. government’s IPv6 mandates, including the OMB Mandate M-21-07 and Federal IPv6 policy requirements. This compliance is vital for organizations that require adherence to federal standards. HashiCorp is currently working with external agencies to achieve full compliance, ensuring Vault Enterprise meets all necessary IPv6 regulations.
Improved User Experience for Security Teams
Vault Enterprise 1.18 introduces improvements in user experience, specifically for security teams. The UI now supports AWS Workload Identity Federation (WIF) and KVv2 secrets path management, simplifying the management of security policies and practices.
UI Support for AWS WIF
Vault previously introduced support for Workload Identity Federation (WIF), which enables secretless configurations between Vault Enterprise and cloud providers like AWS, Azure, and Google Cloud. The new UI support allows security teams to configure AWS WIF directly through the interface, offering a more intuitive workflow for secrets management.
UI Support for KVv2 Secrets Path Management
The KVv2 secrets path management feature now has a UI-driven workflow. This enhancement allows security teams to set policies and manage secrets more effectively, ensuring that users have least-privileged access. By allowing users to see key names and update key-values without read access, Vault aligns with organizational security needs.
Additional Enhancements and Resources
The latest release of Vault also includes various other feature updates, workflow enhancements, and bug fixes. Users can find a comprehensive list of changes in the Vault 1.18 changelog. Additionally, step-by-step tutorials are available on the Vault release highlights page, providing users with guidance on how to leverage the new features effectively.
