How to Secure Your Network Using Synology SRM

Securing your network is no longer optional. With increasing cyber threats, businesses need advanced tools to protect data, control access, and monitor activity. Synology Router Manager (SRM) provides a powerful, user-friendly platform to build a secure and controlled network environment.

This guide explains how to use SRM to strengthen your network security step by step.

Enable the Built-In Firewall

The firewall is your first line of defense.

Steps:

  • Go to SRM Control Panel
  • Enable Firewall
  • Create rules to allow or block traffic

Best Practices:

  • Block unnecessary ports
  • Restrict access to critical services
  • Allow only trusted IP ranges

A properly configured firewall prevents unauthorized access.

Use Threat Prevention for Real-Time Protection

SRM includes a Threat Prevention package that monitors network traffic.

Key Features:

  • Detects malicious activity
  • Blocks suspicious connections
  • Provides detailed logs

This helps identify and stop threats before they impact your network.

Set Up Secure VPN Access

Remote access should always be encrypted.

Steps:

  • Install VPN Server package
  • Configure OpenVPN or IPsec
  • Create secure user profiles

Benefits:

  • Secure remote work access
  • Protects data over public networks
  • Prevents direct exposure of internal systems

VPN is the safest way to access your network remotely.

Building a Long-Term Security Strategy with SRM

Securing your network with Synology SRM should not be viewed as a one-time setup, but as an ongoing strategy that evolves with your business. As organizations grow, so do their network complexities, user access requirements, and exposure to cyber threats. SRM provides a flexible foundation that allows businesses to continuously refine their security posture through regular audits, policy updates, and performance monitoring. By periodically reviewing firewall rules, VPN access logs, and user permissions, administrators can identify outdated configurations or potential vulnerabilities before they are exploited.

Implement Strong Access Controls

Controlling who can access your network is critical.

Use Safe Access to:

  • Create user profiles
  • Set internet usage policies
  • Restrict access to harmful websites

Additional Tips:

  • Disable default admin accounts
  • Use strong passwords
  • Enable multi-factor authentication (MFA)

This ensures only authorized users can access your network.

Segment Your Network with VLANs

Network segmentation reduces risk.

Benefits:

  • Isolate sensitive systems
  • Separate guest and business networks
  • Limit lateral movement during attacks

Using VLANs improves both security and performance.

Monitor Network Activity

Continuous monitoring helps detect issues early.

Use SRM Tools to:

  • Track connected devices
  • Monitor bandwidth usage
  • Review security logs

This provides visibility into your network and helps identify unusual activity.

Enable Automatic Updates

Keeping your system updated is essential.

Why It Matters:

  • Fixes security vulnerabilities
  • Improves system stability
  • Enhances performance

Enable automatic updates to ensure your network stays protected.

Secure Remote Management

If you manage your network remotely:

  • Use HTTPS only
  • Restrict access to specific IP addresses
  • Avoid exposing management ports directly

This prevents attackers from targeting your router interface.

Backup Your Configuration

Always have a backup of your SRM settings.

Benefits:

  • Quick recovery after failure
  • Easy restoration of security policies
  • Reduced downtime

Regular backups ensure continuity.

Combine SRM with NAS Security

For complete protection, integrate SRM with Synology NAS systems.

This allows:

  • Secure data access
  • Controlled file sharing
  • Protected backup environments

A unified approach strengthens overall infrastructure security.
