Network Security Checklist for SMEs

Why Network Security Matters

Your network is the gateway to all company data. A single misconfigured firewall rule or an open WiFi network can expose your entire organisation. This checklist ensures your network is locked down.

Firewall Security

• Review firewall rules quarterly
• Remove rules for decommissioned systems
• Verify logging is enabled
• Check firmware is current
• Document all rule changes

WiFi Security

• WPA3 or WPA2-Enterprise for corporate WiFi
• Separate guest WiFi network
• Change WiFi passwords quarterly
• Disable WPS
• Monitor connected devices

VPN Security

• MFA required for VPN access
• Split tunneling disabled
• VPN logs reviewed monthly
• Certificate-based authentication where possible
