Modern apps require hundreds of secrets to function (API keys, cloud credentials, etc.). However, poor management of these secrets can expose sensitive information publicly or to malicious actors.
Effective secrets management keeps sensitive information safe and avoids breaches. Here’s a guide to managing secrets, the most common challenges, and the best practices that keep systems secure.
What Is a Secret?
In cybersecurity, “secrets” refers to any confidential data that needs protection from unauthorized users. Secrets include the passwords and keys vital for authentication, encryption, and secure system communication. When compromised, they can lead to attacks or breaches, which is why it is so important to manage them properly.
Common types of secrets include:
- API keys: These codes confirm requests between applications.
- Passwords: Passwords are the most widely used method for authenticating both users and systems.
- Cloud credentials: These authentication keys provide access to cloud services like AWS, Azure, and Google Cloud.
- Encryption keys: Encryption protects data by making it unreadable to anyone without access.
- Tokens: These temporary credentials validate users or systems during a session.
- SSH keys: Secure shell (SSH) keys provide secure, encrypted access to remote servers.
What Is Secrets Management?
Secrets management is the process of storing, managing, and controlling access to sensitive information like passwords and encryption keys. The goal is to maintain secret security and minimize the risk of unauthorized access.
Secrets management has become even more critical as organizations shift to multi-cloud environments. In these complex environments, secrets spread across multiple services and systems, making them harder to track and secure.
Having a clear and organized system in place allows for more precise tracking. Plus, some security tools offer automated secrets management to reduce human error, enforce tighter security practices, and ensure compliance.
The Impact of Secrets Management
Secrets management is about more than just protecting passwords. It has a huge impact on a company’s operations and reputation. Many high-profile breaches have occurred due to improper management of secrets—usually when teams haven’t stored or hardcoded sensitive data with the right precautions.
In 2016, Uber suffered a major data breach that exposed the personal data of 57 million customers and drivers. The breach occurred because an attacker was able to access Uber’s private GitHub repository, where sensitive credentials—including AWS access keys—were hardcoded. Once the attackers had these credentials, they accessed Uber’s cloud infrastructure and stole the data. Uber's failure to properly secure these secrets led to a $148 million settlement and a significant hit to the company's reputation.
Exposed secrets could also lead to regulatory violations under the General Data Protection Regulation (GDPR), Health Insurance Portability and Accountability Act (HIPAA), or Payment Card Industry Data Security Standard (PCI DSS). For example, under GDPR, the exposure of personal data due to poor secrets management can result in hefty fines and legal repercussions.
Secrets Management Challenges
The complexity of modern software development makes it challenging to identify, track, and protect secrets. Here are some common roadblocks.
Secrets Sprawl
As your organization adopts more cloud services, containers, and microservices, it gets harder to manage everything. Secrets sprawl happens when secrets are scattered across different platforms and environments, making them difficult to track.
Without a centralized system, you risk duplicating secrets, leaving them in unmonitored locations, or forgetting them in older environments. This broadens the attack surface significantly. To control secrets sprawl, you need a system that offers complete visibility to rotate and manage secrets securely.
Hardcoded Secrets
When secrets are hardcoded into source code, anyone accessing the repository can see them. Teams may forget to protect, rotate, or remove secrets from the code, leaving them vulnerable and making it harder to adjust them down the line.
Instead of embedding secrets in code, use a centralized management system where you can update them without code changes. This way, secrets stay secure and the development process remains efficient.
Insufficient Awareness and Visibility
It’s difficult to secure what you can’t see. If you don’t have visibility into where and how you store secrets, you’re likely missing potential vulnerabilities. For effective secrets management, you need a clear understanding of where sensitive data exists across systems—and what measures are in place to protect it.
Manual Secrets Management
Relying on manual processes to manage secrets increases the chance of human error and slows development cycles. In fast-paced DevOps environments, for example, tracking secrets manually can create bottlenecks, exposing sensitive data longer than necessary. Automating secrets management minimizes these risks and consistently rotates and updates secrets without intervention.
Secrets Management Best Practices: 4 Tips
Here are a few tips for handling secrets effectively.
1. Centralize Secrets Management
Centralizing secrets means consolidating all processes into a single secrets management tool or vault. In this context, a vault represents a secure platform specifically designed for storing and managing secrets.
This approach enforces consistent security policies and streamlines access controls, reducing the chance of human error and avoiding storing secrets in insecure locations like configuration files or repositories.
2. Automate Secrets Rotation
Manually rotating secrets is inefficient and risky—not to mention time-consuming. Automating this process allows for more frequent and accurate updates, protecting data from unauthorized access without requiring manual intervention.
3. Implement Least Privilege Access
With the cybersecurity principle of least privilege, users and systems should only have the permissions they need to perform their roles. This approach minimizes the attack surface and limits damage if a secret is compromised.
4. Regularly Audit and Monitor Secrets
Regular audits and continuous monitoring catch unauthorized access and breaches early. A robust auditing process also lets you track who uses secrets and when, providing valuable insights into security gaps.
What Is a Secrets Management Tool?
A secrets manager helps you securely store, manage, and control access to sensitive information like passwords and cloud credentials. These systems provide a centralized solution for data protection, keeping vital information secure across the entire development lifecycle.
