How Does HashiCorp Vault Work?

Vault is a secure storage system for sensitive data, such as passwords, API keys, and certificates.

First, Vault uses encryption to ensure that secrets are stored securely. When you write a secret to Vault, it is encrypted using a unique key. 

The key decrypts the data when you later read that secret back from Vault. This means that even if an attacker gains access to your Vault instance, they won't be able to read your secrets without the encryption key.

But encryption is just the beginning. Vault also provides a variety of access controls to ensure that only authorized users and services can access sensitive data. 

These controls include fine-grained policies that can be tailored to specific use cases and authentication mechanisms that integrate with existing identity providers.

Vault also provides auditing capabilities to track all access to secrets. This makes it easy to see who accessed what secret and when. This can be useful for compliance purposes or investigating security incidents.

What is HashiCorp Vault Used for?

Now that we know what HashiCorp Vault is and how it works let's look at its use cases. 

Employee Credential Storage

Storing and managing large numbers of usernames and passwords can be challenging for any organization. Vault provides a secure, centralized location for storing and managing employee credentials. 

With access controls, you can ensure that only authorized users can access sensitive data, reducing the risk of passwords being stored insecurely or leaked.

Data Encryption

Vault can be used to encrypt sensitive data, making it unreadable to anyone who doesn't have the proper encryption keys. 

This can be particularly useful for storing data in cloud environments or other untrusted locations. 

With Vault, you can be confident that your data is secure, even if it falls into the wrong hands.

API Key Generation for Scripts

Many scripts require API keys to interact with various services, and managing those keys can be a hassle. Vault can generate API keys on demand, making it easy to manage credentials for your scripts. 

With Vault's API key generation, you can ensure that only authorized scripts can access your services.

General Secret Storage

A vault can be used for general secret storage, providing a secure location for storing sensitive data. This could include anything from SSH keys to database credentials. 

With Vault, you can store all your secrets in one secure location, with access controls to ensure that only authorized users can access them.

Pros & Cons of HashiCorp Vault

HashiCorp Vault is a powerful tool for securely managing secrets and sensitive data. However, like any technology, it has its pros and cons. Here are some of the main ones to consider:

Pros of HashiCorp Vault

All this while maintaining strong security and compliance standards. This can help you reduce the risk of data breaches, improve operational efficiency, and simplify your security workflows.

Robust Security Features

Regarding storing sensitive data, security is always a top priority. And that's where HashiCorp Vault shines. It has a wide range of security features that help keep your secrets safe from prying eyes.

Here are some of the key security features of HashiCorp Vault:

  • Encryption: Vault uses industry-standard encryption to protect your secrets while they're at rest and in transit.

  • Access control: Vault lets you set up fine-grained access controls to ensure that only authorized users and applications can access specific secrets.

  • Audit logging: Vault tracks all access and changes to secrets to easily see who did what and when.

  • Dynamic secrets: With Vault, you can generate short-lived dynamic secrets on-the-fly, which can help reduce the risk of credential theft and unauthorized access.

Faster Release Cycle

HashiCorp Vault is a versatile tool that offers several benefits to its users. One of the major advantages of using Vault is its faster release cycle. 

This means that it releases new features and improvements more frequently. Hence users can get access to the latest updates promptly. 

This also shows that HashiCorp is dedicated to continuously improving the product and providing users with the best experience possible.

This flexibility allows you to choose the deployment model that best suits your organization's requirements without sacrificing security or scalability.

Hassle-Free Self Hosting 

With HashiCorp Vault, you can easily manage your self-hosted environment. 

This gives you full control over your data and eliminates relying on third-party services, which can be expensive and time-consuming to manage.

Here are some of the benefits of self-hosting with HashiCorp Vault:

  • Greater flexibility: You can customize your setup to meet your needs and integrate with your existing infrastructure.

  • Improved performance: With self-hosting, you can optimize your system for speed and reduce latency.

Cons of HashiCorp Vault

It can be Complex

HashiCorp Vault can be complex, especially for users who are not familiar with the technology. Here are a few reasons why some users might find Vault challenging to use:

  • Vault has a steep learning curve: Because of its many features and capabilities, Vault can be difficult to learn for beginners. Becoming comfortable with its various components and the best practices for deploying and managing them might take some time.

  • Requires specialized knowledge: Vault requires specialized knowledge and expertise, especially when configuring its advanced security features. This can make it challenging for smaller teams or organizations with limited resources to use effectively.

  • Can be time-consuming: Setting up and configuring Vault can be time-consuming, especially for users who are new to the technology. This can make it difficult to quickly deploy and use in time-sensitive situations.

Ensuring Security at the Expense of Tedious Inspection

Vault's audit logs are an incredibly powerful tool for ensuring security by tracking who accesses which secret and when. This level of transparency can help you quickly detect and respond to any potential security threats. 

However, the downside of this feature is that it can sometimes be a little too heavy-handed with hashing sensitive information in the logs. That can make it difficult to inspect and extract the data you need.

Vault's hashing of sensitive information in audit logs is great for protecting the data. But it can also be a little confusing to work with, particularly when you need to inspect and extract the data for analysis. 

Unfortunately, there is no simple way to selectively disable hashing for certain values in the logs. This can make inspection and analysis a bit of a headache.

User Interface Limitations

Although it provides a good starting point for basic tasks, more advanced operations require additional API or command-line interface configuration.

For instance, the Vault UI lacks useful features, such as search functionality, making finding specific secrets within a large collection difficult.

In addition, the UI can be slow to load large data sets, making it cumbersome.

Users may also encounter issues accessing certain types of secrets, such as those stored in databases or generated dynamically. 

These limitations can be overcome with additional configuration and custom development, but they can add complexity to the setup process.

Lack of Search Functionality for Secret Keys

One downside of using HashiCorp Vault is the lack of built-in search functionality for secret keys. Searching for a specific key within Vault can be a tedious process. 

Unfortunately, the current version of Vault does not offer a search feature for secret keys.

Users have to manually navigate through the hierarchical structure of the Vault paths to find the desired key. 

This can be especially challenging in large organizations where many teams and applications use the same Vault instance. That can result in a complex and potentially confusing path structure.
