PBX is an essential component that supports the critical functions of your organization. Failing to protect your PBX can expose your organization to toll fraud, theft of confidential information, and loss of revenue. So how can you minimize the risks and protect your business-crucial PBX system from potential attacks? Here are some tips.
Use Strong Passwords
Strong passwords should be used for every password required in your PBX: extension registrations, user web interface and more.
Block Unauthorized Access
Set up firewall rules to block suspicious access and enable the anti-hacking auto-detection mechanism on your PBX.
Separate Voice and Data Traffic
Secure your traffic by utilizing the NGN (Next Generation Network) service provided by VOIP ISPs or setting up VLAN on the PBX.
Keep Your PBX updated
Strong passwords should be used for every password required in your PBX: extension registrations, user web interface and more.
Secure the Trunks on PBX
Prevent toll fraud by restricting the use of outbound call from each vulnerable end-point and disallow anonymous incoming calls.
Avoid Port Forwarding
Port forwarding risks potential attacks by opening a hole in firewall. To offer remote access for your mobile workers, try securer alternatives like VPN.
