Delivering Security on Your Terms: An Intro to Self-Hosted

Setting Up Secure Infrastructure

Building a secure foundation for self-hosted collaboration environments is essential. Below, we break down the key steps to establish a strong and secure infrastructure.

Selecting a Hosting Location

Where you host your system plays a major role in security and data control. Organizations should choose from these three deployment options based on their specific needs:

Network Protection Setup

A strong network defense involves multiple layers. Key steps include:

• Firewall Configuration: Set up strict firewall rules to allow access only to essential services and ports. Use both network- and application-level firewalls for layered protection.
• VPN Implementation: Use a VPN to secure and authenticate all remote connections.
• Network Segmentation: Divide your network into isolated segments to limit damage in case of a breach. This also allows for more precise access control with customizable permissions.

System Requirements

Your hardware setup must meet certain standards to ensure both security and performance. Focus on the following:

• Server Specifications: Use dedicated physical or virtual servers with enough processing power, redundant storage, sufficient memory, and backup power systems. Environmental controls are also important to maintain server integrity.
• Security Hardware:
  • Hardware security modules (HSMs) for encryption tasks
  • Tools for network monitoring
  • Intrusion detection systems
  • Physical access controls to secure server locations

Balancing security with operational efficiency is key when designing your infrastructure.

Installation Security Steps

Following a structured installation process is essential to avoid security risks. Here's how to safeguard your collaboration tools during setup.

Safe Download Sources

The first step to secure installation is verifying your download sources. Always get installation files from:

• Official project repositories
• Verified GitHub releases
• Organization-approved mirror sites
• Authenticated container registries

For container-based deployments, use official Docker images that come with verified digital signatures. After downloading, confirm the file's integrity using the methods outlined below.

File Authentication

Before proceeding with installation, ensure that downloaded files are genuine and intact. Use these verification methods:

Once you’ve authenticated the files, you’re ready to configure your system for security.

Security Configuration

Proper configuration during installation is a critical step. Here are some key measures to implement:

• Encryption Setup
  Activate end-to-end encryption using TLS/SSL protocols and establish secure key management practices.
• Access Control Configuration
  • Enforce strong password rules.
  • Set up session timeouts.
  • Enable IP-based access restrictions.
  • Create admin accounts with limited privileges.
• System Hardening
  • Disable unnecessary services.
  • Update all system packages.
  • Set secure file permissions.
  • Enable intrusion detection and security logging.

User Security Management

Protecting user data and preventing unauthorized access requires effective security management. Here are some key strategies to help secure user accounts and data.

Account Security Rules

A solid foundation for account security starts with clear policies that protect user credentials without sacrificing usability. Below are some critical components to consider:

In addition to these rules, using multi-factor authentication (MFA) adds another layer of security.

Multi-Factor Security

Strengthen account protection by enabling MFA, which requires users to verify their identity through multiple methods. Common MFA options include:

• Time-based one-time passwords (TOTP)
• Hardware security keys
• Biometric verification (e.g., fingerprints or facial recognition)
• SMS verification as a backup

Organizations widely recognize MFA as a critical tool for secure collaboration and data protection.

Permission Controls

Role-based access control (RBAC) ensures users only have access to the data and tools necessary for their responsibilities. Key steps include:

• Creating Custom Roles
  Define permissions tailored to specific job functions. Limit access to sensitive features or data and establish clear hierarchies for permissions.
• Setting Channel Access
  Control who can create channels, share files, and invite external users.
• Implementing Data Controls
  Configure policies for message retention, restrict file access, and enable audit logs to track sensitive actions.

For instance, a public agency successfully applied these strategies to manage secure communications across more than 1 million cases. Regular audits and quarterly reviews of permissions ensure access remains appropriate as roles and responsibilities change. Always document any adjustments to permissions for accountability and transparency.

Security Maintenance

Regularly monitor and manage your self-hosted tools to maintain system integrity and reduce the risk of breaches.

Update Management

Keeping your software up to date is essential for addressing vulnerabilities. Create a structured update plan that includes:

Always back up your system and test updates in a staging environment before rolling them out. Once updates are handled, continuous monitoring becomes your next layer of protection.

Security Tracking

Implementing effective tracking tools can help identify and resolve issues quickly. Focus on these key areas:

• System Logs: Record user actions, authentication attempts, and system changes.
• Performance Metrics: Keep an eye on resource usage and system health indicators.
• Access Reports: Review login patterns and permission changes for anomalies.
• Network Traffic: Analyze data flow to detect unusual activity.

By tracking these elements, you can speed up the resolution process when issues arise.

"We have a much shorter time to detection. When an issue comes up we can reach a solution much faster, because all of the external vendors and internal developers who are on those Rocket.Chat channels will already have seen it, and acted on it together." - Justin Hewitt, Senior Director of DevOps Platform Services

Emergency Response

A well-planned response process is key to minimizing damage during incidents. Here's how to approach it:

1. Detection and Analysis
   • Document suspicious activities.
   • Assign severity levels to incidents.
   • Enable automated alerts for critical issues.
2. Containment Strategy
   • Lock down affected systems.
   • Segment the network to limit spread.
   • Revoke compromised credentials.
3. Recovery Process
   • Restore data from secure backups.
   • Verify system integrity post-recovery.
   • Focus on restoring services as quickly as possible.

Regularly test these procedures to ensure they work effectively when needed.
