What Is Vault?
The security of your organization relies on the integrity of passwords, tokens, encryption keys and permissions belonging to all the human employees and machine users you use everyday for daily operations. How do you ensure that only the users with the right privileged access are entitled to reach vital internal resources and data?
In the age of cybersecurity breaches impacting businesses and enterprises daily, there are steps every DevOps team should take to improving its secrets management. The key lies in a concept called the “vault.”
Why Do We Need Secrets Vaults?
Vaults are for more than just basic usernames and passwords. Enterprises everywhere use a wide variety of authentication tools, including tokens, SSH keys, and certificates to name a few. We refer to all these as “secrets.”
Traditional methods for dealing with the vast pool of secrets across the enterprise are risky and slow. What happens when a low-level user accidentally receives high-level permissions for too long? What if a cyberattack occurs and compromises your servers, some of which may have high-level permissions? How can you efficiently manage all your secrets securely?
The answer is keeping everything centralized in a vault. Vault secrets management not only helps you monitor and track all the secrets across your company but can also help with other cybersecurity-related tasks like password rotation and the removal of excessive standing privileges and adding just-in-time access.
How Is a Vault the Ultimate Secrets Management Tool?
In DevOps, a “vault” typically refers to the specific variant: the HashiCorp Vault. However, we’re going to use it as a generic term for any vault secret manager on the market. No matter what you use, vaults all have a common method for handling complicated enterprise-grade secrets.
Because secrets are so sensitive, you don’t want to keep a list of them anywhere without encryption. Vaults work by encrypting each secret to help prevent unauthorized users from gaining access. They function mostly as an active storage container for secrets as well as an account management system for dealing with multiple privileged accounts across the company.
But where will you keep the encryption keys for all your secrets? A vault is meant to be a centralized place to manage account permissions and secrets.
What Are Some Secrets Management Best Practices?
Adopting a vault platform is the best step towards proper enterprise-grade secrets management. Suitable platforms will always offer functionalities like:
- Dynamic secrets. If you’ve ever used 2-factor authentication, a dynamic secret essentially functions the same way. Instead of using a static password every time, the vault generates a temporary one on-demand to make sure that only authorized users have access.
- Secret rotation. For another layer of security, vaults commonly rotate credentials by changing them regularly. Should a cyberattack impact a privileged account, access is revoked in a short time.
- Privileged access management. Cybercriminals commonly target accounts with elevated permissions, as they have access to the most confidential information and controls. Vaults automatically keep track of granted access for all users and can revoke it whenever suspicious activity is detected.
- Cloud deployment. A vault-as-a-service system is far more efficient in the cloud. Deployment time is much faster, and maintenance is cheaper, especially if it’s outsourced to a third-party provider. The cloud also enables a dynamic approach to infrastructure instead of a static one.
To manage secrets on a growing scale, enterprise administrators are turning to automated vaults for the job.
What Are Some Other Benefits of a Secrets Vault?
DevOps secrets vaults are clearly the best solution for external cyberattacks, hacked accounts, and unnecessary privileged access, but what are some other reasons to adopt a vault platform for your enterprise?
- Centralized control. Secrets belong to hundreds of users across multiple departments in an organization. Instead of having to hunt down each one’s location, a vault keeps everything in the same place.
- More productivity. When employees spend less time looking up passwords and logging in, they can focus more on the task at hand.
- Legal compliance. You may have to audit your secrets at some point for regulatory purposes. Proper PAM tools allow you to audit, manage, and restrict accordingly to match up with data regulations like HIPAA, ICS CERT, FDCC, and FISMA to name a few.
