Hackers will try to use open ports to gain access to vulnerabilities on your network.

Use a business-class firewall that locks access to your network and mitigates the risk of firewallWe recommend replacing your basic router with a SonicWALL network appliance. These include a sophisticated firewall designed to protect your business network security.

2. Password protect your firewall

Router come preconfigured with basic login credentials, always change these and where possible, enable 2FA.

5. Use an Intrusion Protection System (IPS)

An IPS examines network traffic to detect and prevent vulnerability exploits.

Using rules and policies, this can provide an automatic barrier. If a packet is deemed malicious it will block traffic coming from that IP destination or port.

This used in conjunction with a decent firewall can help prevent malicious packets flowing around your network.

6. Use a Web Application Firewall (WAF)

Subscription based applications help protect business network security against web based threats.

A web application firewall can provide a dynamic database of known threats to ensure it is constantly updated.

Web application firewalls also help address compliance requirements for the Payment Card Industry Standard (PCI DSS).

7. Use VLAN’s

business computer securityMost business-class routers can be configured to provide VLANs (Virtual LANs).

VLAN’s can be used to segregate company networks depending on business needs.

VLANs can be configured to provide complete control and help prevent malicious attacks.
