Please Accept The Fact That Password Rotations Are A Security Issue

Welcome to this comprehensive guide where we delve into the often-debated practice of password rotations and its impact on security. Contrary to popular belief, enforcing regular password changes may not always be beneficial for your system’s security. This post focuses on understanding why and how to implement a better approach, particularly for homelab and self-hosted environments.

Introduction

For years, the mantra of “change your password regularly” has been drummed into our heads as a way to enhance security. However, recent findings from the National Institute of Standards and Technology (NIST) challenge this long-held belief. This post aims to help you understand why password rotations can pose issues, and what steps you can take to improve your system’s security without enforcing regular password changes.

Prerequisites

• Operating System: Ubuntu 20.04 LTS or later (recommended) with root access
• Hardware: Minimum 2GB RAM, 10GB disk space
• Software: Password Store (pwsafe) version 4.3.8+ and GnuPG version 2.2+
• Network: Stable internet connection and firewall rules to allow outgoing connections
• User Permissions: Standard user account with sudo privileges

Installation & Setup

1. Update your system:

   sudo apt update -y && sudo apt upgrade -y
   

2. Install Password Store and GnuPG:

   sudo apt install pwsafe gnupg -y
   

3. Create a new GnuPG key for your password store (optional but recommended):

   gpg --gen-key
   

4. Import the GnuPG public key to your Password Store:

   pwsafe importgpg ~/.gnupg/pubring.gpg
   

5. Configure Password Store to use your new GnuPG key (edit ~/.pwsafe/pwsafe.conf):

   [General]
   gnupg_path = /usr/bin/gpg
   gnupg_homedir = ~/.gnupg
   gnupg_keyid = YOUR_GPG_KEY_ID
   gnupg_passphrase_fd = 0
   

   Replace YOUR_GPG_KEY_ID with the ID of your new GnuPG key.

6. Start the Password Store service:

   systemctl start pwsafe && systemctl enable pwsafe
   

7. Verify the service is running and listening on port 12459 (default):

   ss -tulpn | grep 12459
   

Configuration

• Security Hardening: Use strong, unique passwords for your Password Store. Enable two-factor authentication for added security.
• Performance Optimization: Disable automatic updates and consider reducing the frequency of backup.
• Integration with Other Services: Configure Password Store to sync with your favorite password manager or use it in conjunction with LastPass, KeePass, etc.

Usage & Operations

• Common Commands: List available databases (pwsafe list), add a new entry (pwsafe add DB_NAME SECTION SECRET_NAME SECRET_VALUE), and retrieve secrets (pwsafe get DB_NAME SECTION SECRET_NAME).
• Monitoring & Maintenance: Regularly check for software updates, ensure the service is running correctly, and perform routine backups.
• Backup & Recovery: Use the built-in backup feature or create manual backups of your Password Store database.
• Scaling Considerations: Implement a distributed approach with multiple Password Store instances for larger environments.

Troubleshooting

• Common Issues: Connection errors, incorrect GnuPG key usage, and issues with the Password Store service itself.
• Debug Commands & Log Analysis: Use journalctl -u pwsafe to analyze system logs.
• Performance Tuning Tips: Optimize your Password Store configuration for better performance.
• Security Considerations: Implement strict access controls and ensure strong encryption methods are in place.

Conclusion

By following this guide, you have learned how to implement a secure, non-disruptive password management strategy that aligns with the latest security recommendations. As a next step, consider exploring advanced topics such as multi-factor authentication and distributed Password Store deployments for even greater system protection.
