The Network Yeses

by

Secure the Network Perimeter and Traffic

  • Use Business-Grade Firewalls: Replace standard ISP modems/routers with dedicated hardware firewalls to inspect incoming and outgoing traffic.
  • Segment the Network (VLANs): Split your network into virtual sub-networks. Keep corporate traffic, IoT devices (like smart TVs and security cameras), and guest Wi-Fi on isolated subnets so a compromise in one area doesn’t spread.
  • Require Zero-Trust Access for Remote Workers: Never expose internal servers directly to the open internet. Require a s Zero Trust Network Access (ZTNA) for remote connectivity.

Enforce Access Control and Authentication

  • Implement Least Privilege Access: Employees should only have access to the specific network drives, files, and applications required for their role.
  • Mandate Multi-Factor Authentication (MFA): Require MFA for network logins, cloud services, and email systems.
  • Separate Guest Wi-Fi: Always provide a dedicated, isolated guest network that cannot access internal company resources or local servers.

Maintain Network Health and Hygiene

  • Automate Patch Management: Keep network switches, routers, firewalls, and connected endpoints constantly updated with the latest security patches and firmware updates.
  • Monitor Traffic and Performance: Use Network Monitoring Systems (NMS) to track bandwidth usage, spot unusual traffic spikes, and identify failing hardware before it causes downtime.
  • Enforce the 3-2-1 Backup Rule: Keep 3 copies of your data on 2 different media types, with 1 copy stored off-site (or in immutable cloud storage) to recover quickly from ransomware or network failure.

Plan for Growth and Compliance

  • Standardize Hardware: Use consistent, business-grade networking equipment (like Cisco, Ubiquiti, or Aruba) rather than consumer-grade gear to ensure stability and centralized management.
  • Document Network Architecture: Maintain updated network topology diagrams, IP address maps, and vendor contact details to speed up troubleshooting.
  • Establish Acceptable Use Policies (AUP): Clear rules educate employees on proper network usage, preventing accidental exposure to malicious sites or bandwidth hogging.
