Secrets Management Playbook

Overview

Storing secrets such as passwords, API keys, and sensitive data in plain text poses significant risks to your organization. According to IBM’s Cost of a Data Breach Report 2024, stolen or compromised credentials were involved in 16% of all breaches, with an average cost of USD 4.81 million per incident, making them one of the most expensive types of security incidents.

The prevalence and impact of compromised secrets is further validated across multiple industry reports:

• The Verizon Data Breach Investigations Report (DBIR) 2024 found that credential theft was implicated in 19% of breaches.

• Accenture’s State of Cybersecurity Resilience 2023 indicates that poorly protected credentials – often stored in plaintext – significantly extend attacker dwell time, inflating remediation costs.

• Mandiant’s M-Trends 2024 highlights how attackers increasingly leverage compromised secrets to move laterally, especially in cloud environments.

• ENISA’s 2024 Threat Landscape flags inadequate secrets management as a key strategic vulnerability threatening critical services.

The impact of compromised secrets is particularly severe:

• On average, it takes organizations 292 days to identify and contain breaches involving stolen credentials.

• These incidents require extensive investigation and remediation due to the potential for lateral movement across systems.

• The ripple effects often extend beyond immediate systems as compromised credentials can be used to access multiple services and environments.

• Organizations frequently need to undertake costly exercises to identify all potentially impacted systems and revoke/rotate credentials across their infrastructure.

This guide outlines the dangers of plaintext secrets storage, best practices for implementing dedicated secrets management solutions, and practical guidance on incident response and remediation.

Secrets Definitions

What Are Secrets?

Secrets are sensitive credentials such as API tokens, database passwords, SSH keys, certificates, and encryption keys used by software applications, scripts, and infrastructure to establish trust and access control between services. These secrets act as authentication mechanisms, allowing applications to communicate securely without manual intervention. However, they’re often embedded in source code, configuration files, or environment variables, making them vulnerable to exposure if not managed properly.

Secrets Detection

Secrets Detection is the practice of identifying sensitive data points (e.g., hardcoded credentials or access keys) within code repositories, configuration files, CI/CD pipelines, and other environments. Through automated scanning tools and integrations, secrets detection finds potential exposures early in the development lifecycle.

Secrets Management

Secrets Management is the systematic process of storing, handling, rotating, and revoking secrets in a secure environment. It ensures secrets are not embedded directly in application code or configurations, but instead referenced using secure methods and tools – such as dedicated vaults or managed key stores. Effective secrets management enables teams to:

• Control who has access to which secrets.

• Rotate keys and credentials regularly.

• Monitor and audit secret usage.

• Maintain compliance with security regulations and best practices.

Root Causes of Insecure Secrets

Common paths for secrets entering codebases include:

• Developer convenience during local testing: Developers often hardcode credentials while debugging or testing locally, intending to remove them later but occasionally forgetting or accidentally committing them.

• Lack of clear alternatives for configuration management: Without established patterns or tooling for managing configuration and secrets, developers may resort to hardcoding as it appears to be the simplest immediate solution.

• Incomplete infrastructure-as-code practices: When infrastructure deployment is partially automated, sensitive credentials may be included in configuration files or scripts to bridge manual and automated processes.

• Absence of automated checks in CI/CD pipelines: Without pre-commit hooks or automated scanning in CI/CD pipelines, developers lack the immediate feedback needed to prevent secret exposure.

Secrets Detection and Management in Practice

Step 1: Identifying Key Problem Areas

The BlueOptima UI provides the ability to easily identify areas of the codebase with a high prevalence of vulnerable secrets. Start by navigating the BlueOptima UI dashboard to locate areas of high-risk secrets exposure. Apply filters to navigate to the required project or repository. Look for metrics such as frequency of secret exposure and patterns in secret types.

Step 2: Communication Strategies and Finding Champions

Identify security champions within each team to serve as points of contact for enforcing the strategy. Educate these champions on best practices and utilize automated alerts from CI/CD integrations to keep stakeholders informed.

Step 3: Reporting and Feedback Loops

Set up a UI dashboard for team leads and security champions to track progress. Provide summary reports to upper management to highlight the program’s impact on security metrics.

Step 4: Quick-Win Mitigations

Implement an initial series of “quick wins” by scanning and remediating high-risk repositories, educating developers, and rolling out CLI and Pre-commit hook training.

Step 5: Prevent Secrets from Entering Code

Set up CI/CD pipelines to identify secrets and regularly monitor which project’s build fails more often. Setup metrics such as allowing only 1 high-priority secret in build failure per week for monitoring.

Secret Management Strategy

Organizations experience an average cost of $4.81M per breach involving stolen credentials. When evaluating solutions, consider that inadequate solutions often lead to even more expensive remediation efforts later.

A logical initial step is to take stock of current secrets management approaches through an organization-wide scan of the codebase. Requirements for a long-term solution should include:

• Integration Capabilities: Ability to integrate with existing infrastructure and development workflows.

• Security Features: Encryption, access controls, auditing capabilities, and secret leasing.

• Scalability/Uptime: Ability to handle volume and diversity of secrets.

• User Experience: Ease of use for administrators and developers.

• Cost/Maintenance: Costs for support, training, and future audits.

For interim management, the following principles apply: Separate secrets from code; Store as securely as you can; Ensure the same approach is used for all environments.

Industry Best Practices for Effective Secret Management

High Availability

• Redundancy: Ensure redundant components to minimize downtime.

• Disaster Recovery Planning: Develop and regularly test a plan for recovering secrets.

Backup and Recovery

• Backup Critical Secrets: Follow the 3-2-1 rule for critical secrets like cryptographic keys.

• Invalidate and Regenerate: Prefer issuing new secrets over recovering old ones if possible.

• Encryption: Ensure backups are encrypted.

Access Control

• RBAC: Assign permissions based on roles and responsibilities.

• Least Privilege: Grant users the minimum amount of access required.

Encryption at Rest

• Strong Algorithms: Choose algorithms resistant to attacks, such as AES-256.

• Key Rotation: Periodically rotate encryption keys.

Auditing and Monitoring

• Track Access: Record all successful and failed access attempts.

• Monitor Anomalies: Use analytics tools to detect unusual access patterns.

Interim Secret Management

Scanning

Integrating scanning into your development workflow – such as with pre-commit hooks – can greatly reduce the risk of accidental exposure. Even when a corporate solution is eventually implemented, scanning will remain an important component of your overall security strategy.

Separate and Manage

Separate the secrets from the application by storing them in an auditable and access-controlled place, encrypted at rest if possible. Environment variables are often a good starting point, but be aware of the risks of exposure through process listing.

Key interim steps:

1. Run periodic rotations.

1. Review the access audit trail.

1. Add .env files to .gitignore to prevent accidental commits.

1. Remove environment variables after they have been loaded initially.

1. Look at leasing credentials rather than static secrets.

1. Store secrets in an encrypted memory location.

Best Practices for Continuous Improvement

• Role-Based Access Control (RBAC): Grant access to secrets only on a need-to-know basis.

• Avoid exposing the secrets: Fetch secrets dynamically from secure vaults rather than storing them in code or plaintext.

• Regularly Rotate the Secrets: Modify secrets at the organizational level to minimize risk.

• Regularly Review and Update Policies: Align policies with evolving business needs.

• Encourage a Security-First Culture: Promote secure coding practices and provide training.

FAQ for Secrets Management

How Do I Mitigate A Leaked Secret?Identify the areas of impact, rotate the secret (revoke the exposed one and create a new one), and ensure the new secret is handled safely.

How Can I Remove A Secret From Git History?If a secret has been revoked or rotated, it’s generally not necessary to remove it from history. Rewriting history is often ineffective in distributed systems because clones may still contain the old commits.

What Should I Do If I Haven’t Pushed My Commit Yet?Use git commit --amend to modify your commit before it is shared.

Is It Acceptable To Store Secrets In The Codebase For Development?No. This poses significant risks, including the chance of leaking production data into development and creating inconsistent authentication practices.

How Can I Make Hardcoded Credentials Safer If I Cannot Use A Management Solution?Commit a template with no secrets and add the actual credential file to your .gitignore.
